Cook Inlet beluga whale calling varies by group characteristics, behavior, and tidal stateNARA Subscribed
Communication allows social species to exchange information among group members. In aquatic environments, acoustic signals are among the most effective forms of communication and are important for many species, including cetaceans. Beluga whales ( Delphinapterus leucas ) are highly social and vocal, yet little is known about the functionality of their social calls. To examine context-dependent vocal behavior in belugas, we col...
Evolution of research on global amphibian declinesNARA Subscribed
In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on amphibian declines. We sought to provide an example of scientific inquiry in action, from...
There is an urgent need for improved monitoring approaches to rapidly and accurately assess sea cucumber populations at ecologically relevant scales. Timely surveys are critical for informing effective fisheries management and decision-making. Traditional surveys, undertaken via snorkelling, manta tows, or SCUBA, are limited to shallow and accessible areas; however, sea cucumbers inhabit a broad range of depths, including area...
Eutrophication and Warming Drive Algal Community Shifts in Synchronised Time Series of Experimental LakesNARA Subscribed
Lake ecosystems are increasingly impacted by eutrophication and climate change. Whole‐lake experiments have provided ecosystem‐scale insights into the effects of freshwater stressors, yet these are constrained to the duration of monitoring programmes. Here, we leveraged multidecadal monitoring records and century‐scale paleogenetic reconstructions for experimentally fertilised and unmanipulated lakes in the IISD Experimental L...
Plant Responses to a Re‐emergence of Cultural Burning in Long‐Unburnt, Threatened Temperate WoodlandsNARA Subscribed
For tens of thousands of years, Indigenous Peoples have shaped the structure and function of ecosystems through cultural burning, which has many important cultural, ecological, and societal values. In recent years, public interest in cultural burning has increased in response to more severe wildfires globally, and alongside greater calls from Indigenous Peoples for cultural revitalization, as well as generations of Indigenous...
Predicting the invasiveness of alpine newts in the UKNARA Subscribed
Predicting invasion risk to novel environments is essential for risk management and conservation decision making but the evolutionary lineage at which to make these predictions is often unclear. Here we predict the current suitability across the United Kingdom (UK) for the alpine newt Ichthyosaura alpestris , a species with a complex evolutionary history, a broad native range, a growing number of introduced populations and ane...
Phylogenetic origin of an insect fauna at the boundary of the Palaearctic and Oriental realms: Evidence from ‘site‐based’ mitogenomicsNARA Subscribed
Aim Knowledge of taxonomy and species distributions in highly diverse lineages of invertebrates remains too incomplete for the study of biogeographical patterns at the global scale. This limits the understanding of processes leading to the formation and maintenance of boundaries between major biogeographical realms. Site‐based metagenomic approaches may provide an alternative source of data for inference of historical processe...
Cook Inlet beluga (CIB), Delphinapterus leucas , have not recovered from subsistence overharvest despite conservation efforts initiated in 2000. Reasons for this lack of recovery are still unclear with anthropogenic noise identified as a high threat in this population’s recovery plan. Baseline information on CIB habitat use and soundscape characterization is crucial in evaluating impacts from anthropogenic activities. Using pa...
