Adaptive potential in the face of a transmissible cancer in Tasmanian devils
Published: 2024-04-09
Subjects: Life Sciences
Emerging infectious diseases (EIDs) cause catastrophic declines in wildlife populations, but 2 also generate selective pressures that may result in rapid evolutionary responses. One such EID 3 is devil facial tumour disease (DFTD) in the Tasmanian devil. DFTD is almost always fatal, 4 which likely causes strong selection for traits that reduce susceptibility to the disease, but 5 population [...]
Functional team selection: a framework for local adaptation in plants and their belowground microbiomes
Published: 2024-04-09
Subjects: Life Sciences
Plants and their microbiomes are complex adaptive systems consisting of host plants and a dynamic network of associated microorganisms inside and around plant tissues. This article introduces Functional Team Selection (FTS) as a framework to help envision and study the movement of matter, energy, and information within plant-microbiome systems. FTS embraces the fact that belowground, plants are [...]
The destructive sampling conundrum and guidelines for effective and ethical sampling of herbaria
Published: 2024-04-09
Subjects: Biodiversity, Life Sciences
The use of herbaria for science and conservation is revolutionizing the discovery, exploration, and protection of biodiversity at unprecedented scopes and scales. The Global Metaherbarium—a digitally interlinked, open-access resource—is stimulating these efforts and helping to facilitate massive investigations that utilize aggregated digital derivatives of physical herbarium specimens.

Searching for and Monitoring the Nests of Imperiled Grassland Birds: Recommendations from the Grand River Grasslands of Iowa
Published: 2024-04-05
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Grassland birds are the most imperiled avian group in North America, with greater than 50% abundance declines since 1970. Studies examining factors that impact habitat preferences, habitat selection, and reproductive success are critical to developing effective conservation and management plans for these species. These studies often involve searching for and monitoring nests in grasslands, which [...]
Interplay of abiotic conditions, density, and body size in shaping demography in a high-elevation toad population
Published: 2024-04-05
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
In natural populations, vital rates such as survival and reproduction are influenced by a complex interplay of abiotic conditions (e.g., environment), density dependence, and individual factors (e.g., phenotypic traits). Studies at the extremes of species distributions, particularly high elevations, offer unique insights due to the intensified effects of abiotic stressors, which can amplify both [...]
Beyond the buzz: A review of the prospects of replacing meat consumption with insect-based foods
Published: 2024-04-05
Subjects: Agriculture, Food Science, Nutrition
The substantial environmental footprint of meat production means that dietary shifts are needed to reduce greenhouse gas emissions. Insects may offer one alternative. However, to deliver genuine benefits for sustainability of the food system, insects must first be widely accepted and consumed by the general public. In this review, we examine the necessary stages that need to be fulfilled before [...]
Have the environmental benefits of insect farming been overstated? A critical review
Published: 2024-04-05
Subjects: Agricultural and Resource Economics, Agriculture, Food Science
Though insect farming is widely cited as a potential contributor to a sustainable food transition, many of the benefits commonly mentioned by companies and proponents of insect farming are challenged by current evidence. This review examines the evidence used to assess insect farming's environmental benefits and drawbacks for both human food and animal feed. Significant knowledge gaps remain. [...]
Datathons: fostering equitability in data reuse in ecology
Published: 2024-04-05
Subjects: Biodiversity, Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Genetics, Genetics and Genomics, Genomics, Life Sciences, Microbiology
Approaches to rapidly collect global biodiversity data are increasingly important, but biodiversity blindspots persist. We organized a three-day Datathon event to improve the openness of local biodiversity data, and facilitate data reuse by local researchers. The first Datathon, organized among microbial ecologists in Uruguay and Argentina assembled the largest microbiome dataset in the region to [...]
Hotspots of acceleration and demographic processes behind decline of North American birds
Published: 2024-04-04
Subjects: Ecology and Evolutionary Biology, Life Sciences
Human activities might have accelerated declines of population abundances, but this acceleration remains underexplored. Using the North American Breeding Bird Survey, we analyze abundance changes, acceleration, and demographic processes of recruitment and loss across 234 bird species from 1987 to 2021. We show a continent-wide decline of bird abundance, with hotspots of acceleration in the [...]
Ecology and Conservation of Diospyros crumenata (Ebenaceae), a Critically Endangered Tree of the Western Ghats biodiversity hotspot
Published: 2024-04-04
Subjects: Life Sciences
Diospyros crumenata is an IUCN- critically endangered tree species that belongs to the Ebenaceae family and is found in the Western Ghats region. There is limited information about this tree in floristic literature and herbaria, so we conducted extensive forest trips to the Western Ghats to locate its population and study its ecology. Unfortunately, this threatened tree is facing severe threats [...]
No place for phylogeny in structuring a sandy coastal plain community
Published: 2024-04-04
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
Although inference of assembly processes from phylogenetic patterns has become ubiquitous in community ecology, surprisingly few studies simultaneously test assumptions of such an approach and integrate over spatial scales and plant life stages. Here we investigate the roles of phylogeny, functional traits, and abiotic conditions in the spatial structuring of a sandy coastal plain community using [...]
Cladistic species definitions can lead to under-representation of biodiversity from adaptive radiations.
Published: 2024-03-29
Subjects: Life Sciences
Many species are paraphyletic, but current taxonomic practices often do not recognise this, and attempts are made to apply a monophyletic species concept. While allowing the recognition of ecomorphologically equivalent, or even phenotypically indistinguishable allopatric taxa as species, this often leads to combining distinctive local forms (such as cave-adapted populations) or even whole [...]

Children adjust behavior in novel social environments to reflect local cooperative norms inferred from brief exposure
Published: 2024-03-29
Subjects: Anthropology, Social and Behavioral Sciences
Stark intergroup variation in prosocial behavior, as elicited with economic experiments, is evident even though humans are highly mobile. Conformity to local norms has been posited to play an integral role in the maintenance of this variation. Experiments suggest that adults indeed rapidly infer pro- and antisocial norms in a new or changed social environment and adjust their behavior to reflect [...]
Pollination across the diel cycle: a global meta-analysis
Published: 2024-03-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Yet, despite over six decades of research into whether plant reproductive success varies between day and night, consensus remains elusive. We compiled and analysed the [...]
