Recent research illuminates the complex dietary strategies of desert isopods, showing how they balance nutrient intake and rely on environmental microorganisms to optimize digestion and growth. Credit: Moshe Zaguri New insights into the dietary habits of desert isopods unveil the multifaceted elements guiding their food selection. The study reveals that these creatures carefully balance their nutrient intake, favoring biological soil crusts over plant litter, which illuminates the complex web of trophic interactions. By examining the specific eating patterns of desert isopods, this research enhances our comprehension of the delicate relationships among organisms and their habitats, providing valuable implications for ecosystem management and conservation efforts. A new study published in Ecology Letters illuminates the intricate nutritional and functional dynamics influencing the dietary choices of desert isopods (Hemilepistus reaumuri). The research, led by Prof. Dror Hawlena from the Hebrew University’s Institute of Life Sciences and conducted by Dr. Moshe Zaguri (formerly a Ph.D. student at the Hebrew University, now at the Volcani Institute) in collaboration with Prof. David Raubenheimer from the University of Sydney, reveals the complex factors that shape food selection among these fascinating creatures. Foods are complex mixtures of chemical compounds provided in various levels of digestibility that humans and animals ingest for nutritional support. Often, animals need to ingest several food types in order to fulfill their multidimensional nutritional needs and may suffer health consequences by not eating the needed nutrients in specific quantities and ratios. Understanding what considerations influence dietary choices is, thus, a very important but extremely challenging question to study. The authors addressed this challenge by focusing on the simple but mysterious diet of the desert isopods- an interesting species of pill-bug that eats dry leaves and large quantities of nutritionally poor biological soil crust (the upper lair of desert soils that harbor many microorganisms). Isopod siblings start the day by cleaning the burrow before foraging. Credit: Moshe Zaguri The researcher fed isopods with natural and artificial foods and found that when allowing a choice, isopods can tightly regulate their food consumption to meet a very specific ratio of proteins, sugars, and calcium. Isopods receive most of their proteins and sugars from dry leaves and eat soil crust to meet their very high calcium needs. The exoskeleton of isopods is made of calcium carbonates that they must consume in large quantities to grow. However, when isopods could supplement leaf litter with artificial sources of calcium, they successfully met their exact calcium needs, but suffered reduced growth. The authors used gamma-radiation to kill the microorganisms of the soil crust while maintaining its nutritional value and measured the isopods’ food assimilation efficiency and growth rate in comparison to isopods that ate the untreated crust. The authors found that isopods eat the crust to incorporate live microorganisms to their digestive system. Those microbes assist in improving the digestion of the fibrous plant litter. The authors concluded that isopods eat foods that allow them to meet their nutritional needs by providing the nutrients but also by helping them to digest. These revolutionary findings may shed new light on how different animals and humans choose their diet by considering both the foods’ nutrients and the existence of digestive assisting agents. Humans do not eat soil crust but may think about the general insights of this interesting study during their next visit to the local grocery shop. Insights into Isopod Dietary Preferences and Nutrient Optimization Animals optimize their fitness by assimilating specific quantities and ratios of macronutrients and mineral nutrients. To understand this phenomenon, the team conducted extensive field and laboratory experiments focusing on the dietary preferences of desert isopods. Contrary to expectations, wild isopods exhibited a preference for macronutrient-poor biological soil crust (BSC) over plant litter, consuming three times more of the former. The research revealed that desert isopods rigorously regulate their intake of macronutrients and calcium, with phosphorus intake remaining unaffected. Moreover, the team observed that despite equivalent calcium ingestion, isopods thrived better when consuming BSC compared to artificial foods. Notably, isopods consuming gamma-radiation-sterilized BSC exhibited increased consumption but slower growth rates compared to those consuming live BSC, suggesting the crucial role of ingested microorganisms in facilitating litter digestion. Dr. Moshe Zaguri, lead researcher of the study, commented, “Our findings underscore the complexity of dietary decision-making among desert isopods and highlight the importance of considering multifaceted factors in understanding trophic interactions.” Understanding the complex nutritional and functional considerations driving the dietary choices of desert isopods is crucial for advancing our knowledge of ecological dynamics. This research sheds light on how these animals optimize their fitness by regulating nutrient intake and preferring specific food sources. By uncovering the role of ingested microorganisms in facilitating digestion and growth, the study emphasizes the interconnectedness of organisms and their environment. Moreover, it highlights the broader implications for ecosystem management and conservation efforts, underscoring the need for interdisciplinary approaches in ecological research to address the multifaceted factors influencing trophic interactions and ecosystem functioning.

Researchers have discovered a unique microbiome in domestic and laboratory microwaves, with varying microbial communities influenced by food interactions and user habits. This study reveals the potential for biotechnological applications of these microbes, which are similar to those found on kitchen surfaces and industrial environments like solar panels. The microbiome inside microwaves, which is resistant to radiation, is similar to that found on solar panels. Since the Industrial Revolution, microbes have steadily adapted to and colonized a range of new environments, such as marine oil spills, plastic debris in the oceans, industrial brownfields, and even the interior of the International Space Station. However, it turns out that one extreme environment harboring a specialized community of highly adapted microbes is much closer to home: inside microwaves. This finding has now been reported for the first time in a study in Frontiers in Microbiology by researchers from Spain. It’s not only important from the perspective of hygiene, but could also inspire biotechnological applications – if the strains found inside microwaves can be put to good use in industrial processes that require especially hardy bacteria. “Our results reveal that domestic microwaves have a more ‘anthropized’ microbiome, similar to kitchen surfaces, while laboratory microwaves harbor bacteria that are more resistant to radiation,” said Daniel Torrent, one of the authors, and a researcher at the start-up Darwin Bioprospecting Excellence SL in Paterna, Spain. Torrent and colleagues sampled microbes from inside 30 microwaves: 10 each from single-household kitchens, another 10 from shared domestic spaces, for example, corporate centers, scientific institutes, and cafeteria, and 10 from molecular biology and microbiology laboratories. The aim behind this sampling scheme was to see if these microbial communities are influenced by food interactions and user habits. They used two complementary methods to inventorize the microbial diversity: next-generation sequencing and cultivation of 101 strains on five different media. A biodiverse microbiome right at home In total, the researchers found 747 different genera within 25 bacterial phyla. The most frequently encountered phyla were Firmicutes, Actinobacteria, and especially Proteobacteria. They found that the composition of the typical microbial community partly overlapped between shared domestic and single-household domestic microwaves, while laboratory microwaves were quite different. The diversity was lowest in single-household microwaves, and highest in laboratory ones. Members of genera Acinetobacter, Bhargavaea, Brevibacterium, Brevundimonas, Dermacoccus, Klebsiella, Pantoea, Pseudoxanthomonas, and Rhizobium were found only in domestic microwaves, whereas Arthrobacter, Enterobacter, Janibacter, Methylobacterium, Neobacillus, Nocardioides, Novosphingobium, Paenibacillus, Peribacillus, Planococcus, Rothia, Sporosarcina, and Terribacillus were found only in shared-domestic ones. Nonomuraea bacteria were isolated exclusively from laboratory microwaves. There, Delftia, Micrococcus, Deinocococcus, and one unidentified genus of the phylum Cyanobacteria were also common, found in significantly greater frequencies than in domestic ones. The authors also compared the observed diversity with that in specialized habitats reported in the literature. As expected, the microbiome in microwaves resembled that found on typical kitchen surfaces. “Some species of genera found in domestic microwaves, such as Klebsiella, Enterococcus, and Aeromonas, may pose a risk to human health. However, it is important to note that the microbial population found in microwaves does not present a unique or increased risk compared to other common kitchen surfaces,” said Torrent. Parallel evolution However, it was also similar to the microbiome in an industrial habitat: namely, on solar panels. The authors proposed that the constant thermal shock, electromagnetic radiation, and desiccation in such highly irradiated environments have repeatedly selected for highly resistant microbes, in the same manner as in microwaves. “For both the general public and laboratory personnel, we recommend regularly disinfecting microwaves with a diluted bleach solution or a commercially available disinfectant spray. In addition, it is important to wipe down the interior surfaces with a damp cloth after each use to remove any residue and to clean up spills immediately to prevent the growth of bacteria,” recommended Torrent.

Bdelloid rotifer Feeding A new epigenetic mark has been discovered in bdelloid rotifers, involving a horizontally transferred bacterial gene. This gene helps control harmful transposons, protecting the rotifer genome. The discovery introduces a novel gene regulatory system not previously seen in animals. Your DNA holds the blueprint to build your body, but it’s a living document: Adjustments to the design can be made by epigenetic marks. Epigenetic marks are modifications to DNA bases that don’t change the underlying genetic code, but “write” extra information on top of it that can be inherited along with your genome. Epigenetic marks usually regulate gene expression — turn genes on or off — particularly during early development or when your body is under stress. They can also suppress “jumping genes” — transposable elements that threaten the integrity of your genome. In humans and other eukaryotes, two principal epigenetic marks are known. A team from the Marine Biological Laboratory (MBL) has discovered a third, novel epigenetic mark – one formerly known only in bacteria — in bdelloid rotifers, small freshwater animals. This fundamental and surprising discovery is reported this week in Nature Communications. Bdelloid rotifer (Adineta vaga) under polychromatic polarization microscope. Credit: M. Shribak and I. Yushenova Horizontal Gene Transfer “We discovered back in 2008 that bdelloid rotifers are very good at capturing foreign genes,” said senior author Irina Arkhipova, senior scientist in the MBL’s Josephine Bay Paul Center. “What we’ve found here is that rotifers, about 60 million years ago, accidentally captured a bacterial gene that allowed them to introduce a new epigenetic mark that was not there before.” This is the first time that a horizontally transferred gene has been shown to reshape the gene regulatory system in a eukaryote. “This is very unusual and has not been previously reported,” Arkhipova said. “Horizontally transferred genes are thought to preferentially be operational genes, not regulatory genes. It is hard to imagine how a single, horizontally transferred gene would form a new regulatory system, because the existing regulatory systems are already very complicated.” “It’s almost unbelievable,” said co-first author Irina Yushenova, a research scientist in Arkhipova’s lab. “Just try to picture, somewhere back in time, a piece of bacterial DNA happened to be fused to a piece of eukaryotic DNA. Both of them became joined in the rotifer’s genome and they formed a functional enzyme. That’s not so easy to do, even in the lab, and it happened naturally. And then this composite enzyme created this amazing regulatory system, and bdelloid rotifers were able to start using it to control all these jumping transposons. It’s like magic.” A feeding bdelloid rotifer (Adineta vaga) under polychromatic polarization microscope. Credit: M. Shribak and I. Yushenova “You don’t want transposons jumping around in your genome,” said first author Fernando Rodriguez, also a research scientist in Arkhipova’s lab. “They will mess things up, so you want to keep them in check. And the epigenetic system to accomplish that is different in different animals. In this case, a horizontal gene transfer from bacteria into bdelloid rotifers created a new epigenetic system in animals that hasn’t been described before.” “Bdelloid rotifers, especially, have to keep their transposons in check because they primarily reproduce asexually,” Arkhipova said. “Asexual lineages have fewer means for suppressing proliferation of deleterious transposons, so adding an extra layer of protection could prevent a mutational meltdown. Indeed, transposon content is much lower in bdelloids than it is in sexual eukaryotes that don’t have this extra epigenetic layer in their genome defense system.” In the two previously known epigenetic marks in eukaryotes, a methyl group is added to a DNA base, either cytosine or adenine. The team’s newly discovered mark is also a cytosine modification, but with a distinct bacterial-like positioning of the methyl group — essentially recapitulating evolutionary events of over two billion years ago, when the conventional epigenetic marks in early eukaryotes emerged. Resilience of Bdelloid Rotifers Bdelloid rotifers are extremely resilient animals, as the Arkhipova and David Mark Welch labs at MBL have discovered over the years. They can completely dry up (desiccate) for weeks or months at a time, and then spring back to life when water becomes available. During their desiccation phases, their DNA breaks up into many pieces. “When they rehydrate or otherwise render their DNA ends accessible, this might be an opportunity for foreign DNA fragments from ingested bacteria, fungi, or microalgae to transfer into the rotifer genome,” Arkhipova said. About 10 percent of the rotifer genome comes from non-metazoan sources, they have found. Still, the Arkhipova lab was surprised to find a gene in the rotifer genome that resembled a bacterial methyltransferase (a methyltransferase catalyzes the transfer of a methyl group to DNA). “We hypothesized that this gene conferred this new function of suppressing transposons, and we spent the last six years proving that, indeed, it does,” Arkhipova said. It’s too early to know what the implications may be of discovering this new epigenetic system in rotifers. “A good comparison is the CRISPR-Cas system in bacteria, which started out as a basic research discovery. Now CRISPR-Cas9 is used everywhere as a tool for gene editing in other organisms,” Rodriguez said. “This is a new system. Will it have applications and implications for future research? It’s hard to tell.” These discoveries open the door to new tools and research directions to investigate genome function and resilience in this rotifer system. In the future, such knowledge may be applied in creative ways to impact society during this time of rapid environmental change.
