Rapid expansion of insecticide resistance in Acyrthosiphon kondoi and opportunities to improve chemical and biological controlNARA Subscribed
The bluegreen aphid ( Acyrthosiphon kondoi ) is a global pest of pasture and legume crops, damaging plants through feeding and the transmission of plant viruses. Since 2018, Australian growers have reported insecticide control failures involving A. kondoi , with subsequent bioassays confirming the first cases of insecticide resistance in this species worldwide. To better inform management strategies, we conducted a surveillanc...
The impact of acidification on resource competition between native (Faxonius virilis) and non-native (Faxonius rusticus) crayfishNARA Subscribed
One of the most prevalent changes that aquatic ecosystems face due to climate change is the increase of atmospheric carbon dioxide levels resulting in acidification. This study was aimed at understanding how acidification alters behavioral characteristics and competition of two keystone species of crayfish: virile (Faxonius virilis) which were considered native and rusty (Faxonius rusticus) which were considered non-native. Si...
The future of how we understand and manage ecosystems largely depends on direct and continuous observations that connect local territories to planetary processes. Latin America (LATAM: Mexico, Central and South America, and the Caribbean) hosts ecosystems critical for regulating global carbon, water, and energy cycles. However, persistent underinvestment in science and technology hampers the long‐term monitoring capacity neede...
An experimental approach to assess the combined effects of multiple stressors on a large vertebrate speciesNARA Subscribed
The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure. The population of bottlenose dolphins in Barataria Bay, Louisiana, experienced long...
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...
Global patterns and regional insights into kelp forest protection, restoration, and stewardshipNARA Subscribed
Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
Ecological seasonality describes the dynamic adaptation of species to changes in the biotic community and suggests predators should alter space use synchronously with seasonal prey availability. We assessed seasonal space use states (i.e., periods of similar movement and resource use) of mainland gray wolves ( Canis lupus ), moose ( Alces alces ), and white-tailed deer ( Odocoileus virginianus ) on the Grand Portage Indian Res...
The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research NeedsNARA Subscribed
Wildfires, unplanned fires that start and spread under the influence of weather and fuel composition, are increasing in frequency, duration, and severity across North America. While wildfires are one component of wildland fire, a broader natural process in many ecosystems, their changing behavior poses growing ecological and management challenges. Although wildfire is widely recognized as an important disturbance, empirical re...
Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture ManagementNARA Subscribed
Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and management under the ecosystem approach to aquaculture (EAA). Using a focused literat...
Population Genomics of a Cosmopolitan Weed Provides Insights Into Its Local Adaptation and Recent Demographic HistoryNARA Subscribed
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...
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...
