High‐Throughput Sequencing in Aquaculture Disease Investigations: Challenges and Opportunities for ImplementationNARA Subscribed
The current generation of sequencing technologies can produce terabases of data with exceptional accuracy and speed, at a fraction of the cost of older methods. Despite this unprecedented power, adoption into aquaculture health management presents several challenges, including identifying where such capability may be optimally deployed. Here we synthesise discussions from a structured expert workshop held at the 2025 Aotearoa...
Lymphocystis Disease in Endemic Aotearoa New Zealand Bully ( Gobiomorphus cotidianus )NARA Subscribed
We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae , and Kaharore bully, Gobiomorphus mataraerore , also exhibited gross nodular lesions on the fins but were not sampled. Histopathology of G. cotidianus nodular lesions revealed hypertrophic lymphocysti...
Background and aims Agricultural soils in semi-arid sub-Saharan Africa are often low in soil organic carbon (SOC) and nitrogen (N), making them vulnerable to degradation and threatening food security of smallholder farmers. Conservation agriculture practices such as mulching are promoted as climate-resilient strategies to improve soil fertility, but it remains unclear whether these practices improve soil biogeochemical propert...
Predictors and consequences of diet composition in a declining generalist aerial insectivoreNARA Subscribed
For generalist animals that have a broad range of food choices, the specific diet characteristics that are important for health and fitness are often unclear. Here, we examine whether individual variation in diet composition predicts nestling mass and fledge success, and we identify potential drivers of variation in diet composition, in a declining generalist aerial insectivore, the tree swallow ( Tachycineta bicolor ). We col...
Ecology of community reassembly: Movements and diets of megafauna during a decade of restoration in MozambiqueNARA Subscribed
The last decade has brought a worldwide surge of interest in rewilding—the repopulation of large herbivores and carnivores—as a strategy for conserving species and reviving ecosystem functions. Rewilding initiatives, if closely monitored, can provide unique insights into the ecology of the world's largest animals at otherwise impossible spatial and temporal scales. Capitalizing on these opportunities, and developing a knowledg...
The influence of aquaculture translocations and escapees on the genetics of wild stocks of Lates calcarifer in Taiwan and Sri LankaNARA Subscribed
Advances in aquaculture have significantly enhanced food production and contributed to global food security. However, the selective pressures for aquaculture are strong and divergent compared to those occurring in natural systems, and displacement of standing genetic backgrounds by aquaculture backgrounds is a conservation concern across various species. The Asian sea bass or barramundi ( Lates calcarifer ) is a widely propaga...
A general framework for modeling pathogen transmission in co‐roosting host communitiesNARA Subscribed
Cross‐species transmission of pathogens can be facilitated by frequent contact among wildlife. Cross‐species transmission is often driven by phylogenetic similarity between host species, but the role this plays when multiple host species co‐roost is unknown. We developed a generalizable framework for understanding how cross‐species transmission is driven by contact among co‐roosting species spanning evolutionary similarities a...
Contaminants can harm wildlife. However, measuring wildlife exposure to contaminants can be challenging due to accessibility of species and/or sampling tissue matrices needed to assess wildlife health risks. For example, in bats and other taxa that use roosts, collecting feces under colonies minimizes disturbance to species of conservation concern, but fecal contaminant concentrations may not directly correlate with tissue con...
Resilience and vulnerability of the stonefly Nemoura cinerea to increased temperature and droughtNARA Subscribed
Aquatic ecosystems worldwide are under severe pressure from climate change. However, studies on climate change effects on stream biota mainly focus on indicator or vulnerable species, leaving unanswered how more resilient species cope with elevated temperatures and drought, and the long-term consequences for these populations. This study therefore aims to determine the long-term population responses of a common, apparently les...
Simultaneous Detection of Missing Amphibians and Their Fungal Pathogen in a Biodiversity Hotspot Using eDNANARA Subscribed
Since the 1970s, striking amphibian declines in population abundances and presumed extinctions have been recorded globally. The chytrid fungus Batrachochytrium dendrobatidis ( Bd ) is one of the key drivers of these declines. To investigate the potential role of Bd in the decline of Brazil's amphibians, we first used eDNA metabarcoding to survey for DNA traces of 10 threatened amphibian species from the Southern Brazilian Atla...
The effects of global climate change on biodiversity and ecosystem functioning are unevenly distributed in the geographic space. Identifying sites more suitable to sustain biodiversity in a changing climate is essential to both species conservation and restoration strategies at different scales. Here, we map terrestrial climate‐resilient sites for biodiversity across Brazil to identify sites with greater chances of providing s...
Signatures of Polar Vortex Weakening in the MLTI: A ReviewNARA Subscribed
This paper is a collaborative effort that originated at the International Space Science Institute Workshop on “Physical links between Weather and Climate in Space and the Lower Atmosphere” held 22–26 January 2024. Many scientists attended that workshop and contributed their expertise related to polar vortex impacts on upper atmosphere variability. This paper summarizes well-known and newly reported signatures of polar vortex w...
Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin MicrobiomeNARA Subscribed
Shifting precipitation regimes driven by global climate change can alter vertebrate behavior and host‐symbiont relationships, potentially compromising host resistance to pathogen invasion. In Brazil's Atlantic Forest, a biodiversity hotspot, prior research identified drought as a key factor disrupting the skin microbiome, contributing to a die‐off of pumpkin toadlets due to the invasive waterborne fungal pathogen Batrachochytr...
