Biotic Mechanisms Strengthen Functional and Phylogenetic Convergence of Reef Fish Assemblages at Higher LatitudesNARA Subscribed
Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion of competitively inferior species, but most macroecological studies attribute the la...
Ecohydrological Response of a Tropical Peatland to Rainfall Changes Driven by Intertropical Convergence Zone VariabilityNARA Subscribed
Aim Tropical peatlands are globally significant carbon stores, increasingly threatened by human activities and climate change. However, their ecohydrological responses to shifting water availability remain poorly understood. In this study, we investigate the connections between climate change, hydrology and vegetation dynamics in a coastal tropical peatland in Panama, aiming to understand the effects of future drying on peatla...
The gut microbiome holds an important role in the health and homeostasis of fishes. However, despite the large diversity and distribution of this vertebrate group, only the intestinal microbiome of a limited number of freshwater and marine fish species has been well characterized to date. In this study, we characterize the gut mucosal microbial communities of three commercially valuable Scorpaena spp. (n=125) by using a compre...
Acid treatment of Atlantic salmon ( Salmo salar ) scales prior to analysis has negligible effects on δ 13 C and δ 15 N isotope ratiosNARA Subscribed
There is debate in the literature as to whether scales of fishes require acidification to remove inorganic carbonates prior to stable isotope analysis. Acid‐treated and untreated scales from 208 Atlantic salmon from nine locations on both sides of the Atlantic were analysed for δ 13 C and δ 15 N. Linear mixed‐effect models determined the effect of acid treatment to be statistically significant. However, the mean difference was...
Density-dependent growth in ‘catch-and-wait’ fisheries has implications for fisheries management and Marine Protected AreasNARA Subscribed
Stock enhancement activities provide an opportunity to examine density-dependent suppression of population biomass which is a fundamental issue for resource management and design of no-take-zones. We document ‘catch-and-wait’ fisheries enhancement where all but the largest lobsters are thrown back, recapturing them later after they have grown to a larger size. The residency, rate of return, and potential negative density-depen...
Improving predictions of ecological responses to climate change requires understanding how local abundance relates to temperature gradients, yet many factors influence local abundance in wild populations. We evaluated the shape of thermal‐abundance distributions using 98 422 abundance estimates of 702 reef fish species worldwide. We found that curved ceilings in local abundance related to sea temperatures for most species, whe...
Stable‐isotope analysis reveals the importance of soft‐bodied prey in the diet of lesser spotted dogfish Scyliorhinus caniculaNARA Subscribed
This study examines the diet of lesser spotted dogfish Scyliorhinus canicula , one of the most ubiquitous predators of European coastal waters. This species is of increasing ecological significance as other large predatory fish decline as it has known interactions with fisheries. Scyliorhinus canicula diet was investigated in Irish coastal waters during June and July 2014 using both stomach‐content analysis and δ 13 C and δ 15...
Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal...
Pacific Rim Forestry / Silviculture and Forest EcologyNARA Subscribed
Leucaena leucocephala (leucaena) is an important agroforestry tree of tropics and subtropics due to its protein rich foliages, ability to grow on poor soils, and high level of tolerance to various stresses including drought and diseases. We hypothesized that leucaena have a unique set of genes which confer tolerance to various abiotic and biotic stresses and these genes are either absent or not expressed in other legumes that...
