Shelters of Necessity: Exploring the Geoheritage of Dugout Architecture in Early Northwest Texas SettlementNARA Subscribed
This study explores the geoheritage significance of dugouts constructed by early Anglo-American settlers across the Southern High Plains and Rolling Plains of Texas. Geoheritage, which in this study emphasizes the relationship between geodiversity and cultural adaptation, provides a framework to examine how settlers used locally available geological resources for shelter in response to environmental challenges. Fieldwork and a...
Population Genomics and the Environmental Drivers of Population Structure in a Cosmopolitan Marine Predator, Tursiops truncatusNARA Subscribed
The marine environment comprises vast regions without physical barriers to movement, making the understanding of population isolation and the evolution of diversity challenging. This is especially the case for highly mobile marine species. Here we investigate populations of the common bottlenose dolphin ( Tursiops truncatus ) across the Mediterranean Sea and adjacent North Atlantic using high‐resolution genomic markers (RADseq...
Minimising bycatch is a pervasive challenge for sustainable fisheries management, the importance of which is amplified for non‐target species or populations that are in decline. In the eastern Bering Sea (EBS) walleye pollock ( Gadus chalcogrammus ) fishery, salmon—most notably Chinook ( Oncorhynchus tshawytscha ) and chum ( O. keta )—are encountered as bycatch. Salmon bycatch in the EBS pollock fishery has become an issue of...
Brain anatomy of a clonal fish, the Amazon Molly (Poecilia formosa): effects of early-life environmentNARA Subscribed
During ontogeny, environmental factors can shape trait development and resource allocation to aid survival, reflecting adaptive plasticity. This may include differential investment in brain regions in response to cognitive challenges. Especially the brain anatomy of fish seems to respond readily to biotic and abiotic factors. However, we currently lack sufficient data to determine the extent to which such changes are consisten...
Rationale and objectives Overdose fatalities involving cocaine continue to rise with over 5.3 million cocaine users reported in the United States in 2022. The abuse liability of cocaine is reliant upon inhibition of dopamine ( DA ) reuptake and consequent increase in DA efflux in meso-corticolimbic circuitry that controls reward and motivation. Cocaine also increases serotonin ( 5-HT ) efflux which is integral in cocaine abuse...
A Conceptual Framework for Measuring Ecological NoveltyNARA Subscribed
Background Human pressures are driving the emergence of unprecedented, ‘novel’, ecological and environmental systems. The concept of novel (eco)systems is well accepted by the scientific community, but the use and measurement of novelty has outgrown initial definitions and critiques. There are still unresolved methodological and conceptual differences in quantifying novelty that prevent a unified research approach. Framework H...
The use of biological samples from museum and/or archive collections is common in stable isotope research, particularly for marine mammals. Yet, the temporal stability of isotopic values across various tissue types and the influence of different preservatives on these values are not fully understood, posing significant challenges for accurate data interpretation. Here we examine the impact of three different tissue preservatio...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
Russian olive distribution and invasion dynamics along the Powder River, Montana and Wyoming, USANARA Subscribed
The invasive shrub, Russian olive ( Elaeagnus augustifolia ), is widely established within riparian areas across North America and eastern Europe. Limited information on its distribution and invasion dynamics in northern regions has hampered understanding and management efforts. Given this lack of spatial and ecological information we worked with local stakeholders and developed two main objectives: (1) map the distribution of...
Body size and early marine conditions drive changes in Chinook salmon productivity across northern latitude ecosystemsNARA Subscribed
Disentangling the influences of climate change from other stressors affecting the population dynamics of aquatic species is particularly pressing for northern latitude ecosystems, where climate‐driven warming is occurring faster than the global average. Chinook salmon ( Oncorhynchus tshawytscha ) in the Yukon‐Kuskokwim (YK) region occupy the northern extent of their species' range and are experiencing prolonged declines in abu...
