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...

The Toxicology Investigators Consortium 2022 Annual ReportNARA Subscribed
Productivity in the Arctic is expected to increase as temperatures and the number of open water days rise. With this increased productivity, the coastal shelves of the Arctic Ocean may act as a sink for atmospheric carbon. However, this storage is dependent on a sufficient nitrogen (N) supply and current literature on biogeochemical rates of N uptake in this region is severely limited. Here, we report the spatial extent and ra...
A new family of transcriptional regulators of tungstoenzymes and molybdate/tungstate transportNARA Subscribed
Summary Bacterial genes for molybdenum‐containing and tungsten‐containing enzymes are often differentially regulated depending on the metal availability in the environment. Here, we describe a new family of transcription factors with an unusual DNA‐binding domain related to excisionases of bacteriophages. These transcription factors are associated with genes for various molybdate and tungstate‐specific transporting systems as...
Iron‐ and aluminium‐induced depletion of molybdenum in acidic environments impedes the nitrogen cycleNARA Subscribed
Summary Anthropogenic nitrate contamination is a serious problem in many natural environments. Nitrate removal by microbial action is dependent on the metal molybdenum (Mo), which is required by nitrate reductase for denitrification and dissimilatory nitrate reduction to ammonium. The soluble form of Mo, molybdate (MoO 4 2− ), is incorporated into and adsorbed by iron (Fe) and aluminium (Al) (oxy) hydroxide minerals. Herein we...
Size, growth, and density data for shallow‐water sea urchins from Mexico to the Aleutian Islands, Alaska, 1956–2016NARA Subscribed
Size, growth, and density have been studied for North American Pacific coast sea urchins Strongylocentrotus purpuratus , S. droebachiensis, S. polyacanthus , Mesocentrotus (Strongylocentrotus) franciscanus , Lytechinus pictus , Centrostephanus coronatus , and Arbacia stellata by various workers at diverse sites and for varying lengths of time from 1956 to present. Numerous peer‐reviewed publications have used some of these dat...
Understanding the distribution of genetic diversity in the light of past demographic events linked with climatic shifts will help to forecast evolutionary trajectories of ecosystems within the current context of climate change. In this study, mitochondrial sequences and microsatellite loci were analysed using traditional population genetic approaches together with Bayesian dating and the more recent approximate Bayesian comput...
Temporal changes in allele frequencies in a small marble trout Salmo marmoratus population threatened by extreme flood eventsNARA Subscribed
The effect of extreme floods on the genetic composition of marble trout Salmo marmoratus living in Lipovscek, a tributary of the Soca River in Slovenia, which has been affected by multiple destructive flood events for centuries was investigated. By monitoring genetic variability during the period 2004–2011, apparent signatures of genetic erosion including a decline in observed and expected heterozygosities and allelic richness...
Matching oceanography and genetics at the basin scale. Seascape connectivity of the Mediterranean shore crab in the Adriatic SeaNARA Subscribed
Investigating the interactions between the physical environment and early life history is crucial to understand the mechanisms that shape the genetic structure of marine populations. Here, we assessed the genetic differentiation in a species with larval dispersal, the Mediterranean shore crab ( Carcinus aestuarii ) in the Adriatic Sea (central Mediterranean), and we investigated the role of oceanic circulation in shaping popul...
A study on relationships between large‐scale climate indices and estimates of N orth P acific albacore tuna productivityNARA Subscribed
A logistic production model was used to examine potential relationships between three climate indices, the North Pacific Gyre Oscillation ( NPGO ), the Pacific Decadal Oscillation ( PDO ), and the Multivariate El Niño‐Southern Oscillation Index ( MEI ), and productivity estimates of the North Pacific albacore tuna ( Thunnus alalunga ) population. Catch and standardized catch‐per‐unit‐effort data from three longline fisheries (...
Evidence for past and present hybridization in three A ntarctic icefish species provides new perspectives on an evolutionary radiationNARA Subscribed
Determining the timing, extent and underlying causes of interspecific gene exchange during or following speciation is central to understanding species' evolution. Antarctic notothenioid fish, thanks to the acquisition of antifreeze glycoproteins during Oligocene transition to polar conditions, experienced a spectacular radiation to >100 species during Late Miocene cooling events. The impact of recent glacial cycles on this gro...
