Is the future female for turtles? Climate change and wetland configuration predict sex ratios of a freshwater speciesNARA Subscribed
Climate change and land‐use change are leading drivers of biodiversity decline, affecting demographic parameters that are important for population persistence. For example, scientists have speculated for decades that climate change may skew adult sex ratios in taxa that express temperature‐dependent sex determination (TSD), but limited evidence exists that this phenomenon is occurring in natural settings. For species that are...
Sport-related concussions can result from a single high magnitude impact that generates concussive symptoms, repeated subconcussive head impacts aggregating to generate concussive symptoms, or a combined effect from the two mechanisms. The array of symptoms produced by these mechanisms may be clinically interpreted as a sport-related concussion. It was hypothesized that head impact exposure resulting in concussion is influence...
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...
Aquaculture currently accounts for approximately half of all seafood produced and is the fastest growing farmed food sector globally. Marine bivalve aquaculture, the farming of oysters, mussels and clams, represents a highly sustainable component of this industry and has major potential for global expansion via increased efficiency, and numbers of, production systems. Artificial spat propagation (i.e. settled juveniles) in hat...
The fate of genes that cross species boundaries after a major hybridization event in a natural mosquito populationNARA Subscribed
Animal species are able to acquire new genetic material via hybridization and subsequent introgression. However, little is known about how foreign genomic material is incorporated into a population over time and what genes are susceptible to introgression. Here, we follow the closely related mosquito sister species Anopheles coluzzii and Anopheles gambiae in a sympatric natural population in Mali at multiple time points spanni...
Lecanora kohu , a new species of Lecanora (lichenised Ascomycota: Lecanoraceae) from the Chatham Islands, New ZealandNARA Subscribed
Lecanora kohu Printzen, Blanchon, Fryday et de Lange is described as new to science from Rangatira (South East Island), Chatham Islands. It is morphologically similar to L. symmicta (Ach.) Ach., from which it is distinguished by the continuous, areolate thallus, immersed apothecia with pale pink to pink‐brown discs, and by the presence of atranorin and psoromic acid rather than usnic acid, zeorin and xanthones in the thallus....
Technical pre‐analytical effects on the clinical biochemistry of Atlantic salmon ( Salmo salar L.)NARA Subscribed
Clinical biochemistry has long been utilized in human and veterinary medicine as a vital diagnostic tool, but despite occasional studies showing its usefulness in monitoring health status in Atlantic salmon ( Salmo salar L.), it has not yet been widely utilized within the aquaculture industry. This is due, in part, to a lack of an agreed protocol for collection and processing of blood prior to analysis. Moreover, while the ana...
Effective management and conservation of biodiversity requires understanding of predator–prey relationships to ensure the continued existence of both predator and prey populations. Gathering dietary data from predatory species, such as insectivorous bats, often presents logistical challenges, further exacerbated in biodiversity hot spots because prey items are highly speciose, yet their taxonomy is largely undescribed. We used...
Antioxidants, showy males and sperm qualityNARA Subscribed
The fertility of males sometimes correlates with their ornamental display, but we do not have a mechanistic explanation to universally link these traits. We suggest that both sperm quality (fertility; integrity of DNA), and the substrates responsible for male ornamentation, may be vulnerable to free radical attack, which can be mitigated by antioxidants. Support for these ideas is at present weak, and requires validation in ec...
