A Comprehensive Database of Expert‐Curated Occurrences for the Genus Carex L. (Cyperaceae)NARA Subscribed
Motivation Geographic occurrences are essential for biodiversity studies, but publicly available repositories like GBIF often contain errors and biases, especially for taxonomically complex groups like Carex L. (Cyperaceae). This work provides an expert‐curated global dataset of occurrences compiled from different sources to enhance data accuracy and usability. The final dataset includes 384,067 occurrences of 1790 Carex speci...
Fitness costs of pyrethroid resistance in the polyphagous pest mite, Halotydeus destructor, under field conditionsNARA Subscribed
The redlegged earth mite, Halotydeus destructor , is an economically important pest of winter field crops and pastures in Australia, and has evolved field resistance to pyrethroid chemicals through a polymorphism in the voltage-gated parasodium channel leading to knockdown resistance ( kdr) . In this study, we quantified the rate of reversion to susceptibility of partially resistant H. destructor populations under field condit...
Credibility dilemmas under the Paris agreement: explaining fossil fuel subsidy reform references in INDCsNARA Subscribed
Fossil fuel subsidies are a market distortion commonly identified as an obstacle to decarbonization. Yet due to trenchant political economic risks, reform attempts can be fraught for governments. Despite these concerns, an institutionally and economically diverse group of states included references to fossil fuel subsidy reform (FFSR) in their Intended Nationally Determined Contributions (INDCs) under the Paris Agreement. What...
Testing a global standard for quantifying species recovery and assessing conservation impactNARA Subscribed
Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement aga...
Drying microclimates threaten persistence of natural and translocated populations of threatened frogsNARA Subscribed
Defining species habitat requirements is essential for effective conservation management through revealing agents of population decline and identifying critical habitat for conservation actions, such as translocations. Here we studied the habitat-associations of two threatened terrestrial-breeding frog species from southwestern Australia, Geocrinia alba and Geocrinia vitellina , to investigate if fine-scale habitat variables e...
Homogeneous environmental selection dominates microbial community assembly in the oligotrophic South Pacific GyreNARA Subscribed
Oligotrophic subtropical gyres are the largest continuous biomes on Earth and play a key role in global biogeochemical cycles. Microbial communities govern primary production and carbon cycling in the oligotrophic South Pacific Gyre, yet the ecological processes which underpin microbial biogeography in the region remain understudied. We investigated microbial biogeography and community assembly processes at three depths over a...
Fire controls tree cover in many savannas by suppressing saplings through repeated topkill and resprouting, causing a demographic bottleneck. Tree cover can increase dramatically if even a small fraction of saplings escape this fire trap, so modeling and management of savanna vegetation should account for occasional individuals that escape the fire trap because they are “better” (i.e., they grow faster than average) or because...
As landscapes continue to fall under human influence through habitat loss and fragmentation, fencing is increasingly being used to mitigate anthropogenic threats and enhance the commercial value of wildlife. Subsequent intensification of management potentially erodes wildness by disembodying populations from landscape‐level processes, thereby disconnecting species from natural selection. Tools are needed to measure the degree...
The relationship between levels of dominance and species richness is highly contentious, especially in ant communities. The dominance‐impoverishment rule states that high levels of dominance only occur in species‐poor communities, but there appear to be many cases of high levels of dominance in highly diverse communities. The extent to which dominant species limit local richness through competitive exclusion remains unclear, b...
A global database of ant species abundancesNARA Subscribed
What forces structure ecological assemblages? A key limitation to general insights about assemblage structure is the availability of data that are collected at a small spatial grain (local assemblages) and a large spatial extent (global coverage). Here, we present published and unpublished data from 51 ,388 ant abundance and occurrence records of more than 2,693 species and 7,953 morphospecies from local assemblages collected...
A predicted niche shift corresponds with increased thermal resistance in an invasive mite, H alotydeus destructorNARA Subscribed
Aim Predicted distributions of invasive species are often not congruent between their realized native and introduced ranges, but the reasons for this are rarely investigated empirically. We tested for niche shift in an invasive species using a simple framework combining environmental niche models ( ENMs ) and niche‐limiting thermal tolerance traits. Location A ustralia and S outh A frica. Methods The red‐legged earth mite, H a...
Establishing the phylogenetic and demographic history of rare plants improves our understanding of mechanisms that have led to their origin and can lead to valuable insights that inform conservation decisions. The Atlantic coastal plain of eastern North America harbours many rare and endemic species, yet their evolution is poorly understood. We investigate the rare Sandhills lily ( Lilium pyrophilum ), which is endemic to seep...
