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...
Surveys to identify sources of blackleg-causing soft rot Pectobacteriaceae responsible for initial infection of potato cropsNARA Subscribed
Surveys were conducted at two locations in the Netherlands during the growing seasons of 2022 and 2023, to identify sources of blackleg-causing soft rot Pectobacteriaceae (BL-SRP) responsible for initial infections of potato crops. For this, a TaqMan assay for a Pectobacterium brasiliense variant was developed, to allow detection of all BL-SRP variants prevalent in the Netherlands. Leaves of second and third generation prebasi...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Fossil traces of Osedax in dense whale ear bones and thoughts on potential further food sourcesNARA Subscribed
An Oligocene whale ear bone (tympanic bulla) from western Washington State, USA, preserves traces made by the bone-eating marine annelid Osedax . The tympanic bullae of whales are comprised of super-dense, glassy bone and had earlier been hypothesized as being too solid and nutrient poor to attract or sustain Osedax . Computed tomography of the specimen, from an undetermined species of mysticete (baleen whale) and found in the...
Turnover in species composition often lags behind the pace of climate change, resulting in mismatches between climate and communities. However, the impact of these community‐climate disequilibria on ecosystem functions is rarely considered, and current methods for measuring disequilibria assume that species ranges were, until recently, in equilibrium with climate. Here, we develop a simple theoretical model to address both of...
The proportion of individuals that are found to have empty stomachs during a survey of a predator population's diet has been used as an indicator of the average individual's state of energy balance and of the degree to which its feeding rate (i.e., its functional response) is saturated with respect to prey availability. As such, the proportion of empty stomachs provides insights into the effects of prey on predators and vice v...
A synopsis of the genus Maesa (Primulaceae) in New GuineaNARA Subscribed
Summary The genus Maesa in New Guinea is revised. Thirty-nine species are accepted in this study and a key to species (including incompletely known taxa) is presented; four new species, M. begoniifolia, M. pilosopapuana, M. serratifolia, and M. tagulensis are described, and a neotype is selected for the widespread Indonesian species M. tetrandra . Distribution, habitat, phenology and detailed taxonomic notes are provided, and...
