A toolkit for the dynamic study of air sacs in siamang and other elastic circular structures
Published: 2023-10-15
Subjects: Animal Sciences, Biology, Neuroscience and Neurobiology
Biological structures are defined by rigid elements, such as bones, and elastic elements, like muscles and membranes. Computer vision advances have enabled automatic tracking of moving animal skeletal poses. Such developments provide insights into complex time-varying dynamics of biological motion. Conversely, the elastic soft-tissues of organisms, like the nose of elephant seals, or the buccal [...]

Best practices for genetic and genomic data archiving
Published: 2023-09-25
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Genetic and genomic data are collected for a vast array of scientific and applied purposes. Despite mandates for public archiving, data are typically used only by the generating authors. The reuse of genetic and genomic datasets remains uncommon because it is difficult, if not impossible, due to non-standard archiving practices and lack of contextual metadata. But as the new field of [...]

Diversity and function of fluorescent molecules in marine animals
Published: 2023-09-05
Subjects: Biology, Life Sciences, Marine Biology
Fluorescence in marine animals has mainly been studied in Cnidaria but is found in many different phyla such as Annelida, Crustacea, Mollusca, and Chordata. While many fluorescent proteins and molecules have been identified, very little information is available about the biological function of fluorescence. In this review, we focus on describing the occurrence of fluorescence in marine animals [...]
Tick-tock, racing the clock: Parasitism is associated with decreased sprint performance in the Eastern Fence Lizard
Published: 2023-08-27
Subjects: Biology, Life Sciences, Physiology
Host-parasite relationships are important components of ecological systems that influence the evolution of both hosts and parasites. High levels of ectoparasitic infections can disrupt host homeostasis, causing adverse effects on health and performance. However, the effects of natural ectoparasitic levels on host physiology are less understood, with most research designs implementing experimental [...]
Gardens as drivers of native plant dispersal and conservation
Published: 2023-08-25
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
1. Gardens hold untapped potential for participatory biodiversity conservation. Conservation gardening has recently emerged as a way to foster declining native plant species in urban and rural green spaces. But the impact of cultivating these species on population trends in the broader landscape remains underexplored. 2. Here, I study the effects of cultivating herbaceous native plants on [...]
The need of decoding life for taking care of biodiversity and the sustainable use of nature in the Anthropocene - a Faroese perspective
Published: 2023-07-29
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Biodiversity is under pressure, mainly due to human activities and climate change. At the international policy level, it is now recognised that genetic diversity is an important part of biodiversity. The availability of high-quality reference genomes gives the best basis for using genetics and genetic diversity towards the global aims of (i) protection of species, biodiversity, and nature, and [...]
The untapped potential of phage model systems as therapeutic agents
Published: 2023-07-28
Subjects: Biology, Evolution, Life Sciences, Medical Microbiology, Microbiology
With the emergence of widespread antibiotic resistance, phages are an appealing alternative to antibiotics in the fight against multidrug-resistant bacteria. Over the past few years, many phages have been isolated from various environments to treat bacterial pathogens. While isolating novel phages for treatment has had some success for compassionate use, developing novel phages into a general [...]
Recent human-bear conflicts in Northern Italy: a review, with considerations of future perspectives
Published: 2023-07-17
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Zoology
The killing of a runner in Northern Italy by a brown bear (Ursus arctos arctos) and the subsequent investigation of such matter highlighted a Human-Wildlife Conflict (HWC) that has been present in Trentino since the introduction of bears for conservation during the Life Ursus Project. Such conflict may be exacerbated as both human and bear populations get bigger. In this paper, I summarize the [...]
Lipid Metabolism in Parasitoids and Parasitized Hosts
Published: 2023-06-30
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Physiology
Parasitoids have an exceptional lifestyle where juvenile development is spent on or in a single host insect, but the adults are free-living. Unlike parasites, parasitoids kill the host. How parasitoids use such a limiting resource, particularly lipids, can affect chances to survive and reproduce. In part 1, we describe the parasitoid lifestyle, including typical developmental strategies. Lipid [...]
Hypotheses on the extended phenotype of the mitochondrion: sex, mortality, and aging
Published: 2023-06-19
Subjects: Biology, Evolution
How did sex evolve, how is sex evolutionary stable, and why do eukaryotes appear mortal. This paper presents a mitochondrial perspective on the evolution of the eukaryotic cell that appears capable of answering these questions. Rather than viewing a mitochondrion as a passive entity taken up by an archaeal host that remains in the driving seat, mitochondria are viewed as the key force [...]
Academic publishing requires linguistically inclusive policies
Published: 2023-06-05
Subjects: Biology, International and Intercultural Communication, Scholarly Publishing
Scientific knowledge is produced in multiple languages but is predominantly published in English. This academic publishing practice creates a language barrier to the generation and transfer of scientific knowledge between communities with diverse linguistic backgrounds, hindering the ability of scholars and communities to address global challenges and achieve diversity and equity in science, [...]
Trophic interaction models predict interactions across space, not food webs
Published: 2023-05-30
Subjects: Biology
Aim: Trophic interactions are central to our understanding of essential ecosystem functions as well as their stability. Predicting these interactions has become increasingly common due to the lack of empirical data on trophic interactions for most taxa in most ecosystems. We aim to determine whether and how accurately we can extrapolate to new communities both in terms of pairwise predator-prey [...]
Breaking the Ice: A Review of Phages in Polar Ecosystems
Published: 2023-05-28
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Microbiology
Bacteriophages, or phages, are viruses that infect and replicate within bacterial hosts, playing a significant role in regulating microbial populations and ecosystem dynamics. However, phages from extreme environments such as polar regions remain relatively understudied due to challenges like restricted ecosystem access and low biomass. Understanding the diversity, structure, and functions of [...]
