Aging is a complex biological process characterized by molecular changes across multiple biological scales. While these alterations have been extensively studied in humans and rodents, the molecular changes associated with aging in dogs remain underexplored despite their relevance as a model for human aging. In this study, we profiled gene expression ( n = 16,273 genes) and protein abundance ( n = 2041 proteins) in whole blood...
Reborn from the ashes: revision of Beurlenia araripensis Martins-Neto and Mezzalira, 1991 (Crustacea: Decapoda)NARA Subscribed
Beurlenia araripensis was described in 1991 based on a single specimen recovered from the Crato Formation, Araripe Basin, with the type specimen deposited in the Museu Nacional, Rio de Janeiro in 2001. Following the 2018 fire at the museum the holotype was presumed lost, but it was recovered during rescue operations between 2018 and 2022, and fortuitously recognized in 2024. The original description, based on an almost complet...
High rates of dispersal can breakdown coadapted gene complexes. However, concentrated genomic architecture (i.e., genomic islands of divergence) can suppress recombination to allow evolution of local adaptations despite high gene flow. Pacific lamprey ( Entosphenus tridentatus ) is a highly dispersive anadromous fish. Observed trait diversity and evidence for genetic basis of traits suggests it may be locally adapted. We addre...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Trade‐offs and efficiencies in optimal budget‐constrained multispecies corridor networksNARA Subscribed
Conservation biologists recognize that a system of isolated protected areas will be necessary but insufficient to meet biodiversity objectives. Current approaches to connecting core conservation areas through corridors consider optimal corridor placement based on a single optimization goal: commonly, maximizing the movement for a target species across a network of protected areas. We show that designing corridors for single sp...
Microsatellites were used to investigate fine‐scale spatial and temporal genetic structure of a gray seal breeding colony, using samples collected throughout the colony (1997) and more extensive local sampling (2000–2002). Previous behavior of breeding seals on North Rona, including philopatry and high breeding site fidelity, suggested female kin may cluster together. However, low F ST scores indicated no genetic differentiati...
