Ich biete Unterricht, Förderkurse, Vorträge und Fortbildungskurse zu den Themen Naturkunde, Naturschutz, Artenvielfalt, Ökologie, Klimaschutz und Evolution an sowie Unterricht oder Vorträge zur Naturfotografie oder der Naturfilmerei. All dies entweder auf Honarbasis oder via Anstellung. Bitte entnehmen Sie weitere Informationen meinem Menüpunkt zum Thema Unterricht und Lehre. Selbstverständlich verfüge ich über Qualifikationsnachweise zu meinen diversen bisherigen Lehrtätigkeiten sowie meine fachliche Kompetenz. Bitte beachten Sie hierzu auch meinen Menüpunkt Curriculum Vitae.

Doch was sind eigentlich meine Themengebiete? Im Folgenden finden Sie interessante Fragestellungen aus meinen Kompetenzbereichen.

Was ist ein Ökosystem? Welche Ökosysteme sind gut untersucht, welche eher nicht? Wie gut kennt man die Artenvielfalt von Mikro-Lebensstätten in Deutschland, und was ist über deren biologische (ökologische) Zusammenhänge bekannt? Was ist denn eigentlich eine Art, was sind denn dann Zwillingsarten, und was versteht man gar unter einem Artenkomplex (kryptische Artengruppe)? Ist das Aussterben von Arten ein normaler Bestandteil der Evolution oder ist das Aussterben einer Art immer zwingend ein alamierender Hinweis auf eine (evtl. menschengemachte) Naturkatastrophe? Wieviele Arten aus allen Organismengruppen weltweit kennen wir, und wieviele in etwa kennen wir noch nicht? Warum kennen wir viele Arten, sogar in Deutschland, noch immer nicht? Wie erkennt man neue Arten, und wie ist eine sogenannte Artbeschreibung aufgebaut? Ist der Mensch eine Tierart, und wo im Stammbaum der Tiere ist er dann anzusiedeln?

Warum sind ein Wald, ein Teich oder eine Wiese Orte für interessante Entdeckungen, und zwar insbesondere auch für Kinder? Was lebt denn da, und wie ist es an seinen Lebensraum angepasst? Was haben unterschiedliche Arten in solchen Lebensräumen eigentlich miteinander zu tun? Und wie beobachtet man Tierverhalten am besten? Wie dokumentiert man es aussagekräftig, um sein Wissen später mit Freunden oder über soziale Netzwerke teilen zu können?

Wie kommt es zum sogenannten Global Warming, der globalen Klimaerwärmung? Wie können wir sie nachweisen? Warum ist sie zu einem beträchtlichen Teil menschengemacht? Und welche Auswirkungen haben Klimaerwärmung und die Ausbeutung natürlicher Ressourcen (Energiespeicher, Rohstoffe, wie zum Beispiel Tropenholz) für die Zukunft der Menschheit und die Artenvielfalt auf unserer Erde. Welche Auswege erhofft man sich? Woran wird derzeit gearbeitet?

Was benötigt man zur Naturfotografie, was, wenn man zusätzlich oder alternativ auch noch auf gutem Niveau filmen möchte? Was ist grundsätzlich wichtiger: Das Equipment oder das Bild, das zuvor im Kopf des Fotografen oder Filmers entsteht? Muss taugliches Equipment immer ultra-teuer sein? Welche Software eignet sich am besten zum Editieren? Was genügt dabei den Ansprüchen von Anfängern, was benötigen Fortgeschrittene und Profis? Wie filme oder fotografiere ich draußen in der Natur? Wie hole ich stattdessen die Natur in mein Fotostudio und inszeniere sie dort so, dass es aussieht, als habe man im Freien gearbeitet?

Dies sind alles mögliche Themen, die in meinem Unterricht, meinen Kursen oder Vorträgen vertieft werden können. Beliebige weitere Fragestellungen aus den Bereichen Naturkunde, Biologie, Ökologie und Evolution arbeite ich gerne für Sie aus.

I offer lessons, remedial courses, lectures and advanced training courses on the subjects of natural history, nature conservation, biodiversity, ecology, climate protection and evolution, as well as lessons or lectures on nature photography or nature filming. All this either on a fee basis or via employment. Please see my menu item on the subject of teaching for further information. Of course, I have proofs of qualifications for my various previous teaching activities as well as my professional competence. Please also note my menu item Curriculum Vitae. 

But what are my topics? In the following you will find interesting questions from my areas of competence:

What is an ecosystem? Which ecosystems have been well studied and which not? How well do you know the biodiversity of micro habitats in Germany and what is known about their biological (ecological) relationships? What is actually a species, what are sibling species, and what is meant by a species complex (cryptic species group)? Is the extinction of species a normal part of evolution or is the extinction of a species always an alarming indicator of a (possibly human-made) natural disaster? How many species from all groups of organisms worldwide do we know, and roughly how many do we not yet know? Why do we still not know many species, even in Germany? How do we recognize new species and how is a so-called species description structured? Are humans an animal species, and if so, where do they belong in the animal tree?

Why are a forest, a pond or a meadow places for interesting discoveries, especially for children? What lives there and how is it adapted to its habitat? What do different species actually have to do with each other in such habitats? And what is the best way to observe animal behavior? How can you document it meaningfully so that you can later share your knowledge with friends or via social networks? 

How does the global warming come about? How can we prove its existence? Why is it largely human-made? And what are the effects of global warming and the exploitation of natural resources (energy stores, raw materials such as tropical wood) on the future of humanity and biodiversity on our planet? What exits to avoid emergency situations are we hoping for? What are scientists currently working on to ensure a healthy human future? 

What do we need for nature photography, what if we also want to film at a good level in addition or as an alternative? What is fundamentally more important: the equipment or the image that is created in the head of the photographer or filmmaker? Does suitable equipment always have to be ultra-expensive? Which software is best for editing? What meets the requirements of beginners, what do advanced and professionals need? How do we film or take photos outdoors in nature? Instead, how do we bring nature into our photo studio and stage it there in such a way that it looks as if we were working outdoors? 

These are all possible topics that can be deepened in my teaching, courses or lectures. I would be happy to work out any other questions from the fields of natural history, biology, ecology and evolution for you.

Mate guarding of a juvenile female in mites of the Histiostomatidae (Astigmata, Acariformes)

A strategy to avoid male competition for females

.

Some mites of the Histiostomatidae practice so-called mate guarding of subadult females in order to have an advantage in the intraspecific competition between males for adult females. My SEM image shows a male on top of a female, which is still inside its tritonymphal cuticle. Inside the tritonymphal cuticle, the adult female is already developed and shortly before hatching. Before hatching, the legs of the new instar are folded under the body side. The new second leg on the right side is visible in the SEM, because the weak cuticle of the old leg broke off. This strategy to avoid sexual competition is quite common with Histiostomatidae. Due to insufficient mite material and not longer available clear ecological data, I determine the long haired adults of my old SEM series with caution as Histiostoma sp., it seemingly was found around sap flux on a tree trunk in Berlin. The species is not identical with Seliea pulchrum (= Histiostoma pulchrum), typically known from sap flux. The distance between the male legs 1 and 2 in the photo is about 0.1 mm. These SEM objects were seemingly chemically dried for the scanning electron microscopic procedure. The photos were taken around 2005 with an older SEM at FU Berlin. © Stefan F. Wirth Berlin 2022

Mites, Biodiversity, evolution, species extinction, new species

More Specialists are needed to study our biodiversity: recognizing and describing new species, redescribing known ones, mapping their distribution and understanding their ecological role in an ecosystem.Thus we have to support our children and students to become fascinated by nature.

Also interested laypeople, hobby researchers and nature lovers can contribute to species preservation and nature conservation (and thus climate protection) and encourage their children or relatives to study biology or a similar subject.

Es werden mehr Spezialisten benötigt, um unsere Biodiversität zu studieren: neue Arten zu erkennen und zu beschreiben, schon bekannte Arten neu zu beschreiben, ihre Verbreitung zu kartieren und ihre ökologische Rolle in einem Ökosystem zu verstehen. Daher müssen wir unsere Kinder und Schüler dabei unterstützen, sich für die Natur zu begeistern.

Auch interessierte Laien, Hobbyforscher und Naturfreunde können einen Beitrag zum Arten- und Naturschutz (und damit zum Klimaschutz) leisten und ihre Kinder oder Angehörigen für ein Studium der Biologie oder eines ähnlichen Faches animieren.

RAW Berlin as a cultural center in Germany’s capital

The RAW

The RAW (Reichsbahnausbesserungswerk) extends between Warschauer Strasse, Revaler Strasse and Modersonstrasse in the Berlin district of Friedrichshain. The former railway area, which was closed in 1995, is considered to be the largest contiguous and culturally used fallow area in Germany.

Today the ruins are used culturally in a variety of ways. In addition to several clubs and art galleries, there are sports facilities, art studios and various take-out stands.

Self-government and graffiti art

The area is under grassroots self-government.

You can already see art without having to enter galleries, namely in the form of graffiti art, which blends harmoniously and inspiringly into the partly crumbling terrain.

Skate hall and mosaic of architecture, daily life remnants and graffiti

Sports activities are also revealed to the visitor very quickly when entering the area. For example, the skate hall, which opened in 2004/2005, is the only indoor skating facility in Berlin and is internationally well known in that sports scene.

But during my short visit on a summer day afternoon in end of June 2021, I was most impressed by the mosaic of architecture elements, Graffiti and signs of daily life.

Biodiversity research in the US, is the so called American Way always a good basis?

A collegue from the field of entomology recently wrote me his impressions about the situation of scientific fundings in the western world, as he travels around and stays with each of his feet in another country. He said that everybody knows about the importance of the biodiversity on earth and that consequently everybody agrees that research on the biodiversity deserves to be funded. But he continued that this does not mean that the same people would agree that biodiversity research requires experts and that experts would even need to be paid. Thus many of his former students in the US or Germany need to survive with temporary jobs other than their expertises would require.

But also an international unbalance of financial resources, available for fundamental research in entomology or for example acarology (my discipline) can lead to experts being sorted out, although they would be urgently needed. The focus, based on the considered eligibility of research, changed withing the last 25 years. As before Germany was a hotspot for high-quality research in the fields of evolutionary biology, systematics and biodiversity research, that focus of interest is now located in the USA. They invest more money into these sciences than all European countries together.

This can additionally have consequences for the quality of such kinds of research. It is no secret that the general educational level in the US is at least in some areas comparably low, many people don’t speak foreign languages, they often don’t travel abroad, and they live in midst of a mentality, which says „America first“. Biodiversity research would in the old German world of science regularly be connected with many „but consider that…“ conditions. The American way, in some cases, might want to have it easier. They might say: what’s the problem? What do they want to have? Yes, right, they want the numbers of all discovered species. They ask for numbers, thus we do our best to give them numbers, as fast as possible.

Some privileged US-researchers might even misuse their financial power to decide, who in other countries is and who is not. But I say in a rhetoric „you“: Use your fundings to involve as many suffering experts from abroad as possible, instead of center too much work and responsibility on yourself, you won’t have enough time due to too many species, which still need to be discovered and described.  Don’t work too fast and don’t risk to become too superficial. Each species deserves time. Share the work with others and make science benefit from the different kinds of backgrounds in different areas of the world.

Personal aversion or competitor – common reasons for bullying

Bullying is a major weapon in modern times to eliminate competitors or people, which do not fit into the herd of other people or against whom somebody shows a personal aversion. Generally people with individualistic attitudes are endangered to become victims of bullying. The mechanism is often simple: As many people use to follow group dynamics and are open for dogmata, the ability for an independent enquiry is often limited. A „Don’t talk to that Person!“, means for streamlined people frequently „ok, I should not talk to that person“. Why? They don’t ask why.

As bullying is surely a still not fully recognized hidden violence that appears in all kinds of communities, unfortunately even in academic circles, I decided to point out this phenomenon herewith again.  Especially in my fields of fundamental research in systematics and evolutionary biology/ zoology, elbow mentalities are quite common. We need to learn to cooperate, especially when for example financial resources are limited, it’s about our future, and in cases of natural sciences it’s about the future of these sciences.

Mite Histiostoma piceae

The mite Histiostoma piceae Scheucher, 1957 is a member of the mite family Histiostomatidae (Astigmata, Acariformes). Scheucher discovered the mite based on all instars from spruce, infected by the bark beetle Ips typographus. She collected her samples in Regensburg, Höbing (bei Roth) and Harz. Scheucher reared her specimens on potatoes and bran, but describes that her cultures did grow well only to some degree.

According to her findings,  phoretic carrier (hosts) is the bark beetle species Ips typographus, she also found deutonymphs rarely on some staphylinids. She discovered that free living non-deutonymphal stages develop on fresh detritus, while deutonymphs appear only on old detritus („after it was for a longer time removed from the trees“, „wenn der Mulm einige Zeit aus den Bäumen entfernt ist“). I could like Scheucher culture the mites on potato, but a bit better in their original gallery substrate. Under laboratory conditions, they indeed did not rear very well in both kinds of cultures.

I collected H. piceae between 2000 and 2004 once from a wooden log infested by I. typographus in Berlin, then got access to microscopic slides from Europe in the collection of John C. Moser (Louisiana, USA) in 2007 and 2009, then I collected samples from Ips typographus and I. cembrae in Central Croatia (publication Wirth, Weis and Pernek, 2016) and found out that H. piceae is not restricted to I. typographus, but also to its sibling species I. cembrae. I finally collected the mite from I. typographus galleries between 2015 and 2016 in Western-Siberia near the city Tyumen.

I repeatedly observed deutonymphs of H. piceae under natural conditions (bark samples directly after the excursions) to develop in very high numbers, then attaching to all available arthropods nearby, smaller bark beetle species and numerous bigger mites of different groups, such as for example oribatids.

Published recordings of H. piceae from other bark beetles than I. typographus and I. cembrae are doubtful and need to be named Histiostoma cf. piceae. In some cases with I. typographus additionally present, I interpret the mites to have switched from their regular carrier (host) to an adjacent gallery of e.g. another smaller bark beetle species. In other cases, the existence of similar looking species new to science needs to be tested. In cases of determinations by non specialists from bark beetles other than the above mentioned two beetle species, it needs to be assumed that these people could not differ between similar mite species, such as Histiostoma trichophorum Oudemans, 1912, Histiostoma ulmi Scheucher, 1957 or Histiostoma crypturgi Scheucher, 1957.

 

I never before published the full set of SEM and light microscopic photos from these  times (except of my article about host specificity). In this explicite photo publication here on my homepage, I herewith publish SEM-photographs, objects sputtered with gold, which might be not unique to science, but very rare.

Any subsequent research on this mite in Europe is not happening (a few not too relevant findings are published by a former Russian colleague). Reason is that modern science does not understand, especially not in Germany, that fundamental research in applied fields is worth to be funded. It is for example known that deutonymphs of different mite species on bark beetles regularly carry fungus spores (different fungus species, just sticking on the mite’s cuticle), discovered by John C. Moser and confirmed by several of my own publications. This phenomenon is still not closer studied. Fungus transport into bark beetle galleries can influence the micro climate there.

Systematics: Histiostoma piceae is according to my phd thesis from 2004 and according to my more recent research findings a member of a clade (monophylum) within Histiostomatidae with most species associated with bark beetles (Scolytinae) or other bark inhabiting coleopterans; these phylogenetic findings are based on morphological characters.

Mite Histiostoma maritimum

The mite Histiostoma maritimum Oudemans 1914 is a member of the mite family Histiostomatidae (Astigmata, Acariformes). Oudemans discovered the mite based on its deutonymph only from a Dutch island. The German acarologist R. Scheucher found the species in 1957 in mud at the riverside of Regnitz and for the first time could rear H. maritimum and was able to redescribe it by its adult stages, especially females look morphologically conspicuous due to a sclerotized cuticula shield around its copulation opening. She reared her specimens on potatoes, mud and bran, but describes that her cultures did not grow well.

Phoretic carrieres (hosts) are beetles of genus Heterocerus, some carabids and according her findings also rarely some staphylinids.

I discovered H. maritimum between 2000 and 2004 repeatedly in sapropel around ponds in an old gravel pit area in Berlin, forest Grunewald, named „im Jagen 86“. They were mainly attached to the beetles Heterocerus fenestratus and Heterocerus fusculus, but could regularly also be found on the carabids Elaphrus cupreus and Bembidion sp.. I could several times rear the mites, like Scheucher almost unsuccessfully on potatoes, but well on cadavers of their carriers. I thus reconstructed a so called necromenic life-strategy for H. maritium. This means that a phoretic stage ascends a carrier, but never leaves, instead it awaits the carrier’s natural dead to develop on its cadaver (published in my phd thesis, online, 2004).

I will not publish my full set of SEM photos from earlier times here. Some photos will be saved for one of my upcoming paper submissions in scientific and peer-reviewed journals. In this photo publication here on my homepage, I at least publish some interesting SEM-photographs, based on objects sputtered with gold and a subsequent critical-point-drying procedure.

Adults of Histiostoma maritimum: A left male, right female, B, C, copulation opening, D dorsal view to female with mouthparts and copulation opening

Systematics: H. maritimum shares morphological characters of deutonymph (setation, apodemes) and adults (mouthpart details, shape of Digitus fixus) with species like Histiostoma feroniarum, H. insulare, H. litorale, H. palustre, H. polypori, H. myrmicarum. This might indicate a separate clade, but according to the old findings in my phd thesis, also a paraphyletic grouping including these species is thinkable.

Male-Gender discrimination in the natural sciences – unacceptable?

When I was a little child, we used to play all kinds of common child’s plays, such as touch and go or even football, under the motto: boys against girls. But only a few years later in the primary school, such a motto did not exist any more at all. Our teachers wore weird beards, flared trousers or turtleneck pullovers, knitted by themselves, and were pipe smokers, women almost looked the same. They were children of the 1968s, a kind of late hippies in a catholic primary school. Regarding discipline, they were not too tolerant, but there was no separation between genders. We learned that in friendships, the personality of somebody counts, not the gender. I did not differ between male or female school friends. As a young child, you expect this modern and tolerant spirit even growing with the time, but it did seemingly not, times today instead sometimes show a harsh backwards orientation unfortunately.

Everybody talks about gender. They say the female gender is on purpose suppressed by power-hungry men. When I search in social networks for tags, such as #Berlin, #forest, #city or #flowers, I see mostly half naked women, promoting themselves in a tight bikini or by literally simply presenting their breasts. Simple minded neutral observers, may be aliens, would think: ah, interesting, different strategies! While men fight with diligence for their succeeding in life, females choose the more simple way by just showing off.

But I am not simple minded, and I do not know any simple minded people, that’s why I of course analyze such observations and conclude: no, no, no, these are all misconceptions, when it seems that women might use their sexual attraction on men, when they need attention or want to continue their career, then the reality is that they just prove self-determination and independence. When we read in the news that again an almost forgotten Hollywood-star showed off for the Playboy, then we exactly know that she wants to emphasize her feminist ethos by presenting herself like that for the male readers of the journal, simply to set a signal against sexual subjugation to men. Easy to understand! And when unsuccessful actresses accuse famous film directors of sexual harassment from 40 years ago, then this does not indicate a cheap effort to catch public attention at the expense of somebody else. No, no, no, they were just cruelly intimidated in these times decades ago, felt menaced and helpless in a world dominated by powerful and unscrupulous dominant males. It needed so much time to come out in public about what happened, as the today spirit of time finally allows public condemnation without any official trial. So, we learn that feminism did not reach its final peak in the 1970s and 80s, no its going on, and needs to go on and even must be more powerful than ever before, as males still instinctively feel a pressure to suppress women. I support and accept this fight for equality of genders. Viva ultra feminism!

BUT: I would like to draw a line, which should not be crossed. The world of sciences, especially natural sciences, needs to be rid of all kinds of absurd gender discrimination in both directions. My generation of males was obliged to complete either a military service or a civil service. My civil service took me 15 months of my life time. All in all, I lost two years until I could begin studying at a university. Females of my generation finished their studies about two years earlier, which offered them already enough advantage in proceeding with their academic careers and in finding positions. While males in the natural sciences need to prove their work-power permanently by publishing one paper after another, even when unemployed, females go in maternal leave, after they gave birth to their children, and years later of course get in the easiest way a position, without having learned to publish and perform research even without any salaries at all. This goes on costs of the quality of science itself, it thus is fully unacceptable.

But let’s continue: A male with thirty peer-review publications and a woman without any peer-review publications at all apply for the same scientific position. What happens today is in such a situation that based on the so called gender-equality rules, based on woman’s officers and women’s quota, the female applicant needs to be preferred regardless of her qualification and diligence. I had rejected applications, where they officially argued with a necessary preference for a female candidate, based on gender-equality rules. In other cases, they argued to have already decided for another candidate, which was in such cases always a woman. I know a former colleague, who I visited for a short research stay and who had introduced me to his girl friend, who was the same time his official diploma student. A desaster! I heard about a male biologist, who officially criticized the male-gender discrimination in the scientific world in Germany. He was bullied throughout Germany and even Europe so much that he needed to leave the continent, performing now his research in Mexico or Australia, I do not remember. A scandal!

Male gender discrimination in the word of sciences harms the future of science at all!

Christian hate preachers in Germany? The dubious case of a hardliner

He is 53 years old, a hunter and a strength athlete, but Olaf Latzel is unfortunately also an evangelical pastor of the St.-Martini church municipality in the German city Bremen. Livestreams of his church services during times of the corona-crisis since February 2020 had up to 30000 clicks. He and his work are well liked not only in his own municipality. But fortunately, there is also much and harsh criticism against his preaching.

His style of sermonizing is, according to what I saw on his Youtube-Channel, very passionate. His sermons have a very dominant and commanding pitch, and when he talks against homosexuals and other religions, his emotions force his significant nasolabial wrinkles downwards to a grim face, and his eyes peer to the ceiling, when he emphasizes that we had one lord only, and he often shouts an almost hysteric „hallelujah“, when he subsequently continues with statements like „ein Knecht, ein Sklave, hat nur einen Herrn (a servant, a slave, has only one lord)“ and later „kein Knecht kann zwei Herren dienen…(no servant can serve two gods)“. He accordingly is strictly against mixed church services, wants Buddha statues or amulets in households to be destroyed and is such focused on details of ancient text details of the bible that female pastors in his church are not allowed to wear a talar (robe of an evangelical priest) or to preach from the pulpit. Homosexuals are welcome in his municipality only according to the principle „against sins, but for sinners“. Muslims can be treated with mercy, again only following the same principle. But I say: It is a sin to create sinners based o the natural diversity of life!

Apart from discriminating statements against Islam, Buddhism or homosexuals, the slave and servant idea is one of his main topics. According to his preaching, the believers represent nothing else than slaves or servants of god, who even paid for this slave service due to the blood of Jesus Christ. Olaf Latzel is a hardliner, and he does not try to hide this. But the distinct reduction of believers to slaves, to a herd of sheep in the full sense of this term, is also a very clever gambit against individualism, independent free thoughts and criticism. Stupid sheep are easy to control, they ask no critical questions, they even don’t express doubts about statements, written in a thousands of years old ancient book. But there is no god, who demands for thoughtless sheep, there are only very secular authorities in the disguise of religious leaders, who need sheep to fulfill their very secular motivations, namely to live a privileged life on the costs of their slavish subjects. If god preferred sheep instead of humans, he would have appeared as sheep among sheep.

Jesus Christ was the historical human being Jesus from Nazareth. He was an individualist with free thoughts and represented a critic of old and traditional religious attitudes. He considered the stupid human sheep in the Temple in Jerusalem his opponents, and his major aim was to teach and practice charity. His followers were women, who he met as equals, and unmarried men with unknown erotic preferences  (Who knows, may be some considered themselves even as non-binaries!). The disciples of Jesus from Nazareth had a subversive and creative power to modernize the communities, they did not look back to their ancient past, but instead invested their energy in a more human future (at least originally). They today would not find any of their ideals in municipalities with Christian hate preachers.
