This study aimed to identify risk factors related to management practices, environmental conditions, and infrastructure characteristics in nursery and growing–finishing pig farms located in the state of Santa Catarina, Brazil, and their association with the rate ratio of pleuritis at slaughter. A prospective observational study was conducted using a structured survey on 159 growing–finishing farms, totaling 162,252 slaughtered...
Evaluation of alternative antimicrobial strategies in high-performance pigs for managing endemic Mycoplasma hyopneumoniae populationsNARA Subscribed
This study evaluated pig production performance in herds with M. hyopneumoniae by replacing in-feed antimicrobials with the herbal extract carvacrol during nursery and finishing phases. A total of 324 piglets were allocated across three treatments: ATM-Free (without antimicrobial); HE (carvacrol); and ATM (antimicrobial). They were housed in the nursery from 21 to 63 days of age (doa), then transferred to finishing and slaught...
Stranding of a Hector's Beaked Whale ( Mesoplodon hectori ) (Gray 1871) From South Australia Unearths Novel Additional TeethNARA Subscribed
Most extant beaked whales have reduced dentition of one or two pairs of tusk‐like, mandibular teeth that erupt through the gum only in adult males. Additional teeth have been recorded in several species and genera. A juvenile Hector's beaked whale (SAMA M26434) having additional teeth was collected in South Australia and its skeleton and tissues examined. Ultrastructural and chemical data of one additional tooth were obtained...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Effects of snake fungal disease (ophidiomycosis) on the skin microbiome across two major experimental scalesNARA Subscribed
Emerging infectious diseases are increasingly recognized as a significant threat to global biodiversity conservation. Elucidating the relationship between pathogens and the host microbiome could lead to novel approaches for mitigating disease impacts. Pathogens can alter the host microbiome by inducing dysbiosis, an ecological state characterized by a reduction in bacterial alpha diversity, an increase in pathobionts, or a shi...

Future land-use change predictions using Dyna-Clue to support mosquito-borne disease risk assessmentNARA Subscribed
Mosquitoes are known vectors for viral diseases in Canada, and their distribution is driven by climate and land use. Despite that, future land-use changes have not yet been used as a driver in mosquito distribution models in North America. In this paper, we developed land-use change projections designed to address mosquito-borne disease (MBD) prediction in a 38 761 km 2 area of Eastern Ontario. The landscape in the study area...
The CORDEX Flagship Pilot Study ELVIC (climate Extremes in the Lake VICtoria basin) was recently established to investigate how extreme weather events will evolve in this region of the world and to provide improved information for the climate impact community. Here we assess the added value of the convection-permitting scale simulations on the representation of moist convective systems over and around Lake Victoria. With this...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Small freshwater ecosystems with dissimilar microbial communities exhibit similar temporal patternsNARA Subscribed
Despite small freshwater ecosystems being biodiversity reservoirs and contributing significantly to greenhouse fluxes, their microbial communities remain largely understudied. Yet, microorganisms intervene in biogeochemical cycling and impact water quality. Because of their small size, these ecosystems are in principle more sensitive to disturbances, seasonal variation and pluri‐annual climate change. However, how microbial co...
Summary Identifying which abiotic and biotic factors determine microbial community assembly is crucial to understand ecological processes and predict how communities will respond to environmental change. While global surveys aim at addressing this question in the world's oceans, equivalent studies in large freshwater systems are virtually lacking. Being the oldest, deepest and most voluminous freshwater lake on Earth, Lake Bai...
