Gulf sturgeon are federally listed as “threatened” and are native to seven rivers along the northern Gulf of Mexico. Populations natal to the Pascagoula River have one verified spawning reach in the lower Bouie River, near Hattiesburg, MS. This reach is modified by four aggregate mining areas, referred to as pits. Researchers observed post-spawn Gulf sturgeon over-summering in pits rather than migrating to downstream holding a...

Granitic pegmatites are a significant source of critical metals including tin, tantalum, and most notably lithium. To meet future demand, a comprehensive exploration model is required to assist in the discovery of new hard rock deposits. Whereas recent work has largely focused on understanding the source and mineralization processes of pegmatites, the structural controls on the distribution and size of individual deposits rema...

Water pollution from agricultural, industrial, and urban activities threatens aquatic ecosystems and the essential services they provide. Excess nitrogen has been identified as a key driver of water quality degradation, impacting biodiversity, food security, and human health. One approach to mitigating nitrogen pollution is water quality offsetting, compensating for pollution impacts by implementing nitrogen reduction measures...

Invasive plant species present a growing ecological and economic challenge, and often adapt rapidly to their novel environments through complex demographic and evolutionary processes. Invasion genomics offers powerful tools to disentangle these processes, but most studies rely on geographically narrow sampling across native and non‐native ranges. Erigeron canadensis is a cosmopolitan weed native to North America that has succe...

Rationale Polysubstance use, defined as the consumption of more than one addictive substance either simultaneously or sequentially, is an established contributing factor to drug overdose deaths. Almost 80% of opioid-related overdose deaths involve a second substance and 21.6% of these deaths involve cocaine. Beyond increased overdose risk, polysubstance use is also linked to poorer treatment outcomes as well as higher relapse...

While sociality is considered an important factor influencing female reproductive success, it is unclear how temporal social dynamics relate to it. We address this by evaluating the influence of social integration and its stability over time on offspring production and survival in Geoffroy’s spider monkeys ( Ateles geoffroyi ). Using 52,670 subgroup scan samples collected every 20 min for a mean (± SD) of 15 ± 7 scans per day...

Chronic alcohol drinking increases susceptibility to cognitive impairment; however, the underlying mechanisms remain unclear. In this study, we investigated the effects of chronic alcohol drinking on working and recognition memory in a Marchigian Sardinian alcohol-preferring (msP) rat line. Due to interest in insulin-based medications for alcohol use disorder, we examined insulin/insulin-like growth factor 1 (IGF-1) genes in t...
