Southern Israel’s Negev desert is famous for its ancient rock art. Since at least the third millennium BCE, the hunters, shepherds, and merchants who roamed the Negev have left thousands of carvings, known as ‘petroglyphs’, on the rocks. Many represent animals such as ibexes, goats, horses, donkeys, and domestic camels, although some also feature abstract forms. These petroglyphs are typically cut into ‘desert varnish’, a natural thin black coating that forms on limestone rock. Fungus culture: conidia of Alternaria sp. NS1. Credit: Laura Rabbachin, INTK, Academy of Fine Arts, Vienna Fungal Threats to Petroglyphs A study published in Frontiers in Fungal Biology has revealed that the petroglyphs are home to a community of uncommon specialist fungi and lichens. Unfortunately, these species may pose a serious threat to the rock art in the long term. “We show that these fungi and lichens could significantly contribute to the gradual erosion and damage of the petroglyphs,” said Laura Rabbachin, a PhD student at the Academy of Fine Arts Vienna in Austria, and the study’s first author. “They are able to secrete different types of acids that can dissolve the limestone in which the petroglyphs are carved. In addition, the fungi can penetrate and grow within the stone grains, causing an additional mechanical damage.” The landscape around the petroglyphs in the Negev desert. Credit: Laura Rabbachin, INTK, Academy of Fine Arts, Vienna Research Methodology and Findings Rabbachin and colleagues took samples from a petroglyph site in the central-western highlands of the Negev. Here, an average of just 87 mm (3.4 inches) of rain falls per year, and temperatures on rock surfaces can soar up to 56.3 °C (133 °F) in summer. The researchers scraped samples from desert varnish next to petroglyphs, from rocks without desert varnish, and from soil near the sampled rocks. They also left petri dishes open near the rocks to capture airborne spores. The authors identified collected fungi and lichens with two complementary methods. First, they repeatedly cultured fungal material or spores from rocks or soil on plates with one of two different growth media, until they obtained pure isolates for DNA barcoding. Second, they directly performed DNA sequencing of fungal material present in rock or soil samples, without culturing them first. The latter method can detect strains that don’t grow in culture.

Credit: Laura Rabbachin, INTK, Academy of Fine Arts, Vienna Both methods showed that the diversity and abundance of species on rocks bearing petroglyphs was low in comparison with the soil, which suggests that few species can withstand the local extremes of drought and temperature. DNA barcoding of cultured isolates revealed that the petroglyphs harbor multiple species of fungi within the genera Alternaria, Cladosporium, and Coniosporium, while direct sequencing further detected multiple species in the genera Vermiconidia, Knufia, Phaeotheca, and Devriesia. All except Alternaria and Cladosporium are so-called microcolonial fungi, known to thrive in hot and cold deserts around the world. Also abundant were lichens in the genus Flavoplaca.

For example, they have been implicated as a probable cause of the deterioration of stone cultural heritage in the Mediterranean,” said Rabbachin. “Lichens are also well known to cause rocks to deteriorate and thus to be a potential threat to stone cultural heritage.” In the surrounding soil and air, the researchers mainly found different, cosmopolitan fungi, which are known to be able to survive harsh desert conditions through the production of drought-resistant spores.

Credit: Dr Irit Nir, Ben Gurion University of the Negev Impact and Conservation Challenges Can anything be done to protect the petroglyphs from the slow but destructive work of the observed microcolonial fungi and lichens? This is unlikely, cautioned the authors. “These natural weathering processes cannot be stopped, but their speed of the weathering process depends heavily on whether and how the climate will change in the future. What we can do is to monitor the microbial communities over time and most importantly, document these valuable works of art in detail,” said Rabbachin’s academic supervisor Prof Katja Sterflinger, the study’s senior author.

Recent research has upended traditional views on Baird’s beaked whales by discovering a population that thrives in shallow, coastal waters near the Commander Islands. This adaptation highlights the importance of understanding the diverse behaviors and habitats of whale species for effective conservation efforts. Credit: Olga Filatova, University of Southern Denmark Certain creatures inhabit regions of the world so secluded and unreachable that researching them in their natural environments is almost unattainable. Among these are the beaked whales, with 24 identified species to date. These mammals reside far from the coast, in the deep waters of the ocean, diving to depths of over 500 meters in search of food. The record holder for the deepest dive by a mammal is a Cuvier’s beaked whale, which in 2014 was measured to dive at least 2992 meters. A beaked whale also holds the mammalian record for the longest dive; 222 minutes. Now, the world gets a new and surprising insight into the world of distant beaked whales through a scientific study of a population of Baird’s beaked whales. The population has unexpectedly been found near the coast and in shallower waters than previously observed. The study is led by whale biologists Olga Filatova and Ivan Fedutin from the University of Southern Denmark/Fjord&Bælt, and it is published in the journal Animal Behaviour. Filatova and Fedutin have many years of whale studies in the northern Pacific behind them, and it was during an expedition to the Commander Islands in 2008 that they first saw a group of Baird’s beaked whales near the coast. “We were there to look for killer whales and humpback whales, so we just noted that we had seen a group of Baird’s beaked whales and didn’t do much about it. But we also saw them in the following years, and after five years, we suspected that it was a stable community frequently visiting the same area. We saw them every year until 2020, when Covid-19 prevented us from going back to the Commander Islands,” explains Olga Filatova, a whale expert and postdoc at the Department of Biology and SDU Climate Cluster, University of Southern Denmark.

Coastal Habitats and Whale Behavior The studied population of Baird’s beaked whales came close to the coast – within four km of land, and they were observed in shallow water; less than 300 meters. “It is uncharacteristic for this species,” says Olga Filatova, who also points out that the population likely has adapted to this particular habitat and thus deviates from the established perception that all beaked whales roam far out at sea and in deep waters. “It means that you cannot expect all individuals within a specific species to behave the same way. This makes it difficult to plan species protection – in this case, for example, you cannot plan based on the assumption that beaked whales only live far out in deep sea. We have shown that they can also live in shallow and coastal waters. There may be other different habitats that we are not aware of yet,” says Olga Filatova. There are many examples of individuals from the same whale species not behaving the same. In the whale world, it is common to find groups of the same species living in different places, eating different prey, communicating differently, and not liking to mingle with fellow species in other groups.

Some humpback whales migrate between the tropics and the Arctic, others are residents in certain areas. Some sperm whale groups develop their own dialects for internal communication and do not like to communicate with others outside the group. According to Olga Filatova, social learning is at play when groups develop preferences for, for example, habitats and prey. There are many forms of social learning in the animal world. Imitation is the most complex form; the animal sees what others do and understands the motivation and reasoning behind it. Then there is “local enhancement,” where an animal sees another animal heading to a specific place, follows, and learns that the place has value. This has been observed in many animals, including fish. Cultural Traditions Among Beaked Whales Olga Filatova believes that the population of Baird’s beaked whales at the Commander Islands learns through “local enhancement”: They see that some peers go to the shallow water near the coast, follow, and discover that it is a good place, probably because there are many fish. “It becomes a cultural tradition, and it is the first time a cultural tradition has been observed among beaked whales,” she says. Other examples of cultural traditions in whales include when they develop specific hunting traditions: some slap their tails to stun fish, some generate waves to wash seals off ice floes, and some chase fish onto the beach. The researchers observed a total of 186 individuals of the Baird’s beaked whale species at the Commander Islands from 2008-2019. 107 were only observed once and thus assessed to be transient whales. 79 individuals were spotted for more than one year and were thus assessed to be residents. 61 of the transient whales were seen interacting with the residents, and seven of them were seen in shallow water. “The transients are not as familiar with local conditions as the residents, and therefore, they usually seek food at the depths that are normal for their species. But we actually observed some transients in the shallow area. These were individuals who had some form of social contact with the residents. It must be in that contact that they learned about the shallow water and its advantages,” says Olga Filatova. It is unclear how many Baird’s beaked whales exist in the world.

The horseradish flea beetle Phyllotreta armoraciae is capable of accumulating large amounts of mustard oil glucosides (glucosinolates) in its body, making itself unpalatable to predators. Glucosinolates are defense substances of mustard, rapeseed, horseradish, and other plants of the cabbage family. Crucial to the sequestration of glucosinolates in the beetle are special transporters localized in the excretory organ. These transporters prevent glucosinolates that have been absorbed into the body from being excreted. Credit: Anna Schroll Researchers elucidate how the insect regulates the accumulation of plant toxins via special transporters. When horseradish flea beetles feed on their host plants, they take up not only nutrients but also mustard oil glucosides, the characteristic defense compounds of horseradish and other brassicaceous plants. Using these mustard oil glucosides, the beetles turn themselves into a “mustard oil bomb” and so deter predators. A team of researchers from the Max Planck Institute for Chemical Ecology in Jena, Germany, has now been able to demonstrate how the beetle regulates the accumulation of mustard oil glucosides in its body. The beetles have special transporters in the excretory system that prevent the excretion of mustard oil glucosides. This mechanism enables the horseradish flea beetle to accumulate high amounts of the plant toxins in its body, which it uses for its own defense. (Study published today, May 11, 2021, in the journal Nature Communications.) Sequestration: Well-armed with the weapons of others Many animals use chemical defense compounds to deter predators. These defense compounds are either produced by the animal itself or by symbionts of the animal, or they are acquired from the diet. The ability to acquire defense compounds from the diet is particularly widespread in insects that feed on toxic plants. One example is the horseradish flea beetle (Phyllotreta armoraciae), which can sequester mustard oil glucosides, also known as glucosinolates, in its body. “The horseradish flea beetle belongs to an economically important group of insects, because several Phyllotreta species are crop pests. This beetle, which can accumulate vast amounts of host plant glucosinolates, regulates the levels and composition of glucosinolates in the body at least partially by excretion. This suggested that Phyllotreta armoraciae possesses very efficient transport and storage mechanisms, which we wanted to uncover,” says first author Zhi-Ling Yang, explaining the goal of the new study. The team led by Franziska Beran, head of the Sequestration and Detoxification in Insects Research Group at the Max Planck Institute, has already been able to demonstrate how the horseradish flea beetle effectively uses glucosinolates from its host plant to defend itself against a predatory ladybug (see press release, “Whether horseradish flea beetles can deter predators depends on their food plant and their life stage,” March 2, 2020). Special transporters for plant toxins in the excretory system of the beetles Although it has long been known that horseradish flea beetles and related species can accumulate glucosinolates, how the beetle absorb and store high amounts of these substances in the body was unknown. The research team’s goal, therefore, was to identify glucosinolate transporters in this insect. “The search for these transporters was literally like looking for a needle in a haystack,” recalls Beran, “We found 1401 putative membrane transporters in the gut and excretory system of this beetle. Narrowing down our search to transporters that are specific for the horseradish flea beetle helped us to identify a group of glucosinolate-specific transporters.” These glucosinolate transporters are located in the excretory system, the so-called Malpighian tubules. The function of the Malpighian tubules in insects is similar to the function of the kidneys in vertebrates. The scientists determined the function of the identified transporters by using RNA interference, an approach in which the expression of a gene of interest is reduced in order to determine its function in the organism: “We silenced the expression of several transporter genes that are localized in the Malpighian tubules and found that the beetles excreted more glucosinolates than a control group of beetles with normal gene expression. Because of the higher excretion rate, the levels of defense compounds in the beetle body went down. Our study is the first to identify transporters in the Malpighian tubules that enable an insect to accumulate plant defense compounds,” Yang summarizes. With their study, the researchers show that sequestration is a complex process and much more than just the uptake of plant metabolites into the animal’s body. The sequestering insect must adapt its entire physiology to use plant defense compounds for its own defense. These adaptations are driven by challenges in its environment: predators, parasites, and pathogens. “Sequestration is probably one of the most complex adaptations that herbivorous insects have evolved. It most certainly also contributes to the evolutionary success of insects that specialize in certain host plants, such as the horseradish flea beetle,” says Beran. Beran’s team now wants to identify other transporters involved in sequestration. The scientists also want to know which natural enemies of the horseradish flea beetle the glucosinolates are providing protection from. Increased knowledge of how the horseradish flea beetle sequesters toxins and the effects on its ecological interactions with other organisms in the environment, will improve understanding of this pest and may lead eventually to better strategies for its control.
