Spatially explicit capture–recapture (SECR) methods are used widely to estimate animal population density and related parameters. Maximum likelihood has been applied to two flavors of the SECR model—a full model that includes absolute density as a spatially varying parameter, and a model conditional on the number of detected individuals that assumes uniform density. We show how the conditional model may be extended to estimate...
Endophytic Fungi Associated with Seaweeds as Potential Producers of Antimicrobial CompoundsNARA Subscribed
The urgent need for new molecules capable of targeting multidrug-resistant microorganisms has redirected bioprospecting efforts toward less explored marine environments and their associated communities, such as marine mycobiota. This study aimed to evaluate the antimicrobial potential of endophytic fungi isolated from various seaweed species and infer the mechanisms of action and chemical profile of most potent fungal extracts...
Few published studies of moth mating behavior provide adequate details about the lighting conditions under which observations are optimal whilst not disturbing the insects. Fewer than 32% ( n =420) of publications detailed specifics about the light type, color or the output used, and of those that did ( n =133) more than half reported on only one of these aspects. Eueupithecia vollonoides moths are exceptionally sensitive to h...
The cherry barb (Puntius titteya) is a staple of the ornamental aquaculture industry, with an estimated 60,000 individuals produced monthly in Florida, USA. On a commercial scale, small improvements in efficiency may yield considerable economic and operational benefits. This study investigated first-feeding protocols aimed at reducing the use of live Artemia spp. nauplii by evaluating microdiets (MDs) top-dressed with feed att...
Decomposing Frequency Dependence on Selection and Population Growth: Implications for Carrying Capacity and MaladaptationNARA Subscribed
The phenotypes of individuals within a population create a dynamic social environment that influences phenotypic selection and population growth. Fluctuations in the frequencies of these phenotypes can influence population mean fitness and the relative fitness of phenotypes, and thus impact both population dynamics and phenotypic evolution. Various theoretical frameworks have been used to study the impact of frequency dependen...
This study investigates the hygrothermal aging behavior and thermomechanical properties of as-manufactured glass fiber-reinforced epoxy and thermoplastic composite tidal turbine blades. The blades were previously deployed in a marine environment and subsequently analyzed through a comprehensive suite of material characterization techniques, including hygrothermal aging, dynamic mechanical analysis (DMA), tensile testing and X-...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Remotely Sensed Fire Heterogeneity and Biomass Recovery Predicts Empirical Biodiversity ResponsesNARA Subscribed
Aim To compare field‐based evidence of plant and animal responses to fire with remotely sensed signals of fire heterogeneity and post‐fire biomass recovery. Location South‐eastern Australia; New South Wales. Time Period 2019–2022. Major Taxa Studied A total of 982 species of plants and animals, in eight taxonomic groups: amphibians, birds, fish, insects, mammals, molluscs, plants and reptiles. Methods We collated 545,223 plant...
Spatial confinement to a home range is theorized to be a more energetically efficient method of acquiring resources than random searching due to spatial memory. Intraspecific studies that have compared home range size at different population densities have found that home ranges shrink as population density increases. This negative trend could be due to increased conspecific competition via population density increase or due t...
Diabetes mellitus is a major risk factor for frailty in older adults, and studies suggest that frailty risk may differ by diabetes treatment regimen. To investigate the association between diabetes medication use and frailty, we conducted an observational cohort analysis of older adults with diabetes enrolled in the ASPirin in Reducing Events in the Elderly (ASPREE) study. Diabetes at baseline ( N = 2045) was defined as self-r...
