Understanding population structure and connectivity is essential for effective fisheries management, particularly for wide-ranging marine species like permit ( Trachinotus falcatus ). We investigated the genetic structure and diversity of permit at ecologically important locations (e.g., nursery habitats and spawning sites) in South Florida and Southern Belize using mitochondrial Cytochrome Oxidase C Subunit I (COI) sequences....
Diet of juvenile skipjack herring Alosa chrysochloris : Ontogenetic shifts, predator–prey size ratios and mouth gape allometryNARA Subscribed
The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi River (fish n = 6), Illinois River (fish n = 181) and Ohio River (fish n = 255) and t...
Dryland ecosystems cover 41% of Earth's land surfaces, account for 44% of cultivated lands and 60% of food sources, and make large contributions to the global water and carbon cycles. However, these ecosystems are experiencing unprecedented extremes including heatwaves, floods, and droughts as well as hotter temperatures and often declining water resource availability. These ecosystems are some of the most challenging to monit...
From Points to Landscapes: Measuring and Scaling Up Methane Emissions From Mound‐Building TermitesNARA Subscribed
Termites represent a critical but poorly constrained source in the global methane (CH4) budget. This commentary addresses the “scaling paradox” highlighted by Yatsko et al. (2026), demonstrating that the primary drivers of CH4 emissions shift dramatically between individual species, single mounds, and broader landscapes. We expand on this framework using field data from massive Macrotermes mounds in South Africa, which reveals...
The hyperiid amphipod Brachyscelus rapacoides is a warm-water species associated with gelatinous zooplankton. In the Mediterranean it has been reported in association with Rhopilema nomadica in both Israel and Turkey. Here, we document the first record of B. rapacoides in Greek waters, representing the first confirmed record for Europe, based on both morphological examination and DNA barcoding of the mitochondrial COI gene. Sp...
Estimating spatial patchiness of a threatened marine snail based on movement behaviorNARA Subscribed
Normally diffuse animals may group together in patches to facilitate reproduction and enhance survival in the ocean. However, consideration of spatial patchiness is not common in management frameworks, which often use mean abundances instead. Animals, such as queen conch ( Aliger gigas ), that congregate in patches at high density are often heavily harvested, resulting in overexploitation. To better understand the drivers of s...
Ecology and mechanisms of brood raiding of Iridomyrmex by the thermophilic ant, Melophorus anderseniNARA Subscribed
Melophorus anderseni is a thermophilic ant species that nests near colonies of Iridomyrmex on which it conducts brood raids. We examined its colony founding behavior and foraging ecology to evaluate possible mechanisms that may facilitate interspecific nest raiding, as well as determine if it is a parasite or specialist predator. Specifically, we (1) examined colony establishment and survival, (2) patterns of worker activity (...
Advances in near-real-time forecasts of lava flow advance rates, final travel distance, and areal coverage are transforming hazard response, particularly in locations such as Hawaiʻi that experience frequent lava flow activity. The most severe threats are posed by rapidly advancing channelized ʻaʻā flows, such as those that characterized the November–December 2022 eruption of Mauna Loa volcano. To constrain rheological inputs...

Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Methane is a potent greenhouse gas, which traps significantly more heat than carbon dioxide over short timescales, but remains underrepresented in models used for projecting future climate scenarios, particularly in permafrost landscapes. Understanding methane dynamics in northern wetlands is critical for improving projections of high‐latitude carbon feedbacks to the global climate system. To address this, we integrated ecolog...
