Environmental Predictability in Phylogenetic Comparative Analysis: How to Measure It and Does It Matter?NARA Subscribed
Aim Abiotic environmental conditions shape ecological and evolutionary processes, yet quantifying their influence on organisms remains challenging due to variation among metrics and their intercorrelations. This study evaluates the utility of temporal environmental predictability measures and assesses their explanatory power in phylogenetic comparative analyses. Innovation We systematically compare widely used metrics of predi...
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...
Pond methane dynamics, from microbial communities to ecosystem budget, during summer in AlaskaNARA Subscribed
Ponds play a larger role in the global freshwater methane (CH 4 ) budget than predicted from surface area alone. To improve our understanding of pond CH 4 dynamics, we measured summer CH 4 production, concentrations, and emissions to the atmosphere in nine Alaskan wetland ponds along with potential physical, chemical, and biological regulators. Pond CH 4 production (0.64, 0.086–1.3 mmol m −2 d −1 ; median, interquartile range)...
The Australian National Rabbit Database: 50 yr of population monitoring of an invasive speciesNARA Subscribed
With ongoing introductions into Australia since the 1700s, the European rabbit ( Oryctolagus cuniculus ) has become one of the most widely distributed and abundant vertebrate pests, adversely impacting Australia's biodiversity and agroeconomy. To understand the population and range dynamics of the species and its impacts better, occurrence and abundance data have been collected by researchers and citizens from sites covering a...
Despite significant contributions of inland lakes to the global methane cycle, we lack a process‐based understanding of what regulates inter‐lake variation in methane emissions. Previous comparative work has identified a potential link between lake primary productivity and methane emissions; also, lab‐scale experiments suggest that the addition of algal substrate to anoxic sediments rapidly enhances rates of methanogenesis. Th...
