In a rapidly warming Arctic, genetic variation might serve to buffer organisms against the effects of environmental change, such as sea ice loss and ocean warming. Yet, this concept remains largely unexplored because comprehensive genome‐wide studies across the full ranges of Arctic marine taxa are rare. Bowhead whales ( Balaena mysticetus ) have a strong association with sea ice and polar water masses, a long history of human...
Evaluating MPA success for Caribbean reef fish: the role of design, habitat, and managementNARA Subscribed
Marine protected areas (MPAs) are essential tools for protecting marine ecosystems; yet, their effectiveness varies across regions. In the Caribbean, home to some of the world’s most degraded reefs, evaluating MPA performance requires consistent ecological data and information on management practices. To address this, we conducted standardised reef fish surveys of small (< 20 cm) and large (≥ 20 cm) fish across 83 sites in ten...
Integrated Reanalysis of Global Riverine Fish eDNA Datasets Shows Robustness and Congruence of Biodiversity ConclusionsNARA Subscribed
The analysis of environmental DNA (eDNA) has revolutionized biodiversity assessments in aquatic ecosystems, enabling non‐invasive monitoring of fish communities across diverse regions. However, the global comparability of these eDNA datasets remains ambiguous due to heterogeneous sampling protocols and bioinformatic workflows across studies, making it difficult to assess how robust and comparable the biodiversity patterns infe...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Haploid embryogenic cultures of maize (Zea mays L.): stability, doubling efficiency, and use in gene editingNARA Subscribed
Embryogenic cultures were initiated from haploid and diploid seedlings of maize inbred LH244 and monitored for ploidy stability by flow cytometry over the course of six mo. Both culture types were transformed with three different constructs using Agrobacterium tumefaciens to compare transformation and gene editing frequencies. Paromomycin resistant cell lines were split prior to plant regeneration, and half of the tissue was t...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Mangroves are one of the most important Blue Carbon ecosystems within the tropics and subtropics, capturing and storing more atmospheric carbon dioxide per unit area than terrestrial forest systems. There is large variation in estimates of carbon stocks of mangroves in Central America, due to differences in underlying geomorphology, localised environmental conditions, and species composition, which also vary between the Pacifi...

Clarifying the Taxonomy of the Finch Louse Fly Ornithomya Fringillina (Curtis) (Diptera: Hippoboscidae) – An Analysis of MorphotypesNARA Subscribed
Background The louse flies in the genus Ornithomya Latreille are avian ectoparasites. The patterns of alar microtrichia on the wings of the Ornithomyae are commonly used to help distinguish the various species, with the patterns in most species found to be constant between individuals. The Finch Louse Fly Ornithomya fringillina (Curtis) in the United Kingdom, Ireland and the Isle of Man, is unusual in that the several patterns...
Gopher Tortoise (Gopherus polyphemus) burrow associate communities are depauperate in modified landscapesNARA Subscribed
The Gopher Tortoise ( Gopherus polyphemus ) is considered a keystone species because its burrows provide refuge for an entire suite of other species (hereafter burrow associates) that occupy the habitats in which it resides. The Gopher Tortoise has declined across its range in large part due to habitat loss and land use change resulting in burrow abandonment or reduced burrow density, and the concomitant negative effects on bu...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
