Salivary Cortisol as a Measure of Acute Stress and Diurnal Adrenal Activity in Bottlenose DolphinsNARA Subscribed
Monitoring changes to animals' physiological states in managed settings is critical in modern animal welfare assessment. Under human care, marine mammals can be conditioned for voluntary biological sample collection, reducing effects of handling stress on physiological state, thus better reflecting normal physiology. This study validated the use of salivary cortisol in bottlenose dolphins as an alternative to blood cortisol fo...
Ocean acidification can negatively affect a broad range of physiological processes in marine shelled molluscs. Marine bioeroding organisms could, in contrast, benefit from ocean acidification due to reduced energetic costs of bioerosion. Ocean acidification could thus exacerbate negative effects (e.g. reduced growth) of ocean acidification and shell borers on oysters. The aim of this study was to assess the impact of ocean aci...
Regional invasion history and land use shape the prevalence of non‐native species in local assemblagesNARA Subscribed
The ecological impact of non‐native species arises from their establishment in local assemblages. However, the rates of non‐native spread in new regions and their determinants have not been comprehensively studied. Here, we combined global databases documenting the occurrence of non‐native species and residence of non‐native birds, mammals, and vascular plants at regional and local scales to describe how the likelihood of non‐...
Demographic history shapes North American gray wolf genomic diversity and informs species' conservationNARA Subscribed
Effective population size estimates are critical information needed for evolutionary predictions and conservation decisions. This is particularly true for species with social factors that restrict access to breeding or experience repeated fluctuations in population size across generations. We investigated the genomic estimates of effective population size along with diversity, subdivision, and inbreeding from 162,109 minimally...
Subtropical systems experience occasional severe floods, dramatically altering the phytoplankton community structure, in response to changes in salinity, nutrients, and light. This study examined the effects of a 1:100 year summer flood on the phytoplankton community in an Australian subtropical bay – Moreton Bay – over 48 weeks, from January to December 2011. Immediately after maximum flood levels were reached on the rivers f...
A review of inclusive business models and their application in aquaculture developmentNARA Subscribed
For aquaculture to continue along its current growth trajectory and contribute towards achieving the Sustainable Development Goals, value chains must become more inclusive. Smallholders and other local value chain actors are often constrained by circumstances and market failures in the global aquaculture industry. Integrating these actors into aquaculture value chains through inclusive business models (IBMs) is often touted as...
Reconstruction of the demographic and evolutionary history of populations assuming a consensus tree‐like relationship can mask more complex scenarios, which are prevalent in nature. An emerging genomic toolset, which has been most comprehensively harnessed in the reconstruction of human evolutionary history, enables molecular ecologists to elucidate complex population histories. Killer whales have limited extrinsic barriers to...
Heterosis of juncea canola under terminal drought conditionsNARA Subscribed
We measured benthic denitrification (DN) and dissimilatory reduction of nitrate to ammonium (DNRA) using the isotope‐pairing technique in three tropical estuaries in Thailand (Mae Klong), Indonesia (Cisadane), and Fiji (Vunidawa‐Rewa) during rainy, dry, and intermediate seasons along the salinity gradient of each estuary. DNRA dominated. Anammox (AN) was measured initially but neither AN activity nor AN bacteria‐related 16S ri...
Physiological and environmental regulation of interannual variability in CO 2 exchange on rangelands in the western United StatesNARA Subscribed
For most ecosystems, net ecosystem exchange of CO 2 (NEE) varies within and among years in response to environmental change. We analyzed measurements of CO 2 exchange from eight native rangeland ecosystems in the western United States (58 site‐years of data) in order to determine the contributions of photosynthetic and respiratory (physiological) components of CO 2 exchange to environmentally caused variation in NEE. Rangeland...
Physiographically sensitive mapping of climatological temperature and precipitation across the conterminous United StatesNARA Subscribed
Spatial climate data sets of 1971–2000 mean monthly precipitation and minimum and maximum temperature were developed for the conterminous United States. These 30‐arcsec (∼800‐m) grids are the official spatial climate data sets of the U.S. Department of Agriculture. The PRISM (Parameter‐elevation Relationships on Independent Slopes Model) interpolation method was used to develop data sets that reflected, as closely as possible,...
Interannual variability in carbon dioxide fluxes and flux–climate relationships on grazed and ungrazed northern mixed‐grass prairieNARA Subscribed
The annual carbon (C) budget of grasslands is highly dynamic, dependent on grazing history and on effects of interannual variability (IAV) in climate on carbon dioxide (CO 2 ) fluxes. Variability in climatic drivers may directly affect fluxes, but also may indirectly affect fluxes by altering the response of the biota to the environment, an effect termed ‘functional change’. We measured net ecosystem exchange of CO 2 (NEE) and...
