Unlabelled: Hunting wild animals for food and income, which is pervasive across tropical regions, drives biodiversity loss. Interventions to promote sustainable wild meat harvesting require information on hunter behavior. Here we monitored the hunting activities of 33 hunters in SE Nigeria over three years (1,106 hunter-months) to identify correlates of (a) the probability of initiating a hunting trip on any given day; (b) trip success - whether an animal was caught, and if so, how many; and (c) carcass price. We found a higher probability of initiating a trip during periods with bright moon phases and in peak agriculture season. Hunters were more likely to catch at least one animal when there was less rainfall and on shorter hunting trips. However, among successful trips, the number of animals caught increased with trip duration. Taken together, these results suggest hunters set themselves a minimum target of not returning empty-handed rather than optimally adjusting their hunting effort. Lastly, the carcass price per kilogram of a species' meat increased with its palatability but decreased with mass, with the fall in price observed to be greater for rarely caught, smaller-bodied animals than more frequently caught animals. Our results provide deeper insights into the behavioral plasticity of wild meat hunters.

The absence of reliable identification technologies limits the authentication of geographical origin and growth conditions in large yellow croakers (LYCs). This study addressed this issue by analyzing odor and taste-active compounds to enable effective differentiation and quality evaluation. The findings revealed that inorganic sulfides, alcohols, aldehydes, ketones, nitrogen-containing oxides, and methyl compounds served as potential odor markers for the rapid discrimination of LYC meat from various origins, with 3-methyl-1-butanol and hexanal identified as key distinguishing odor compounds.

Accumulated evidence supports the critical role of migratory wild birds in highly pathogenic avian influenza virus (HPAIV) spread and evolution. An effective surveillance strategy to study HPAIV dispersal in wild birds and identify critical interfaces between wild birds and poultry on the landscape for potential interspecies transmission and virus evolution will be essential. This study integrates conditional likelihood with epidemiological research designs to investigate the risk of poultry farm outbreaks due to the introduction of HPAIV by migratory birds from the Taiwan citizen scientist dataset.

The demand for wild animal meat, popularly called "bushmeat", serves as a driving force behind the emergence of infectious diseases, potentially transmitting a variety of pathogenic bacteria to humans through handling and consumption. This study investigated the microbial load and bacterial diversity in bushmeat sourced from a prominent bushmeat market in Kumasi, Ghana. Carcasses of 61 wild animals, including rodents (44), antelopes (14), and African civets (3), were sampled for microbiological analysis.

The cytosine base editor (CBE) enables precise C-to-T substitution without inducing DNA double-strand breaks, which offering a promising tool for editing livestock genomes to enhance economically valuable traits. In this study, using Hu sheep, characterized by high reproductive performance but suboptimal meat production as the research subject, two CBE-editing sgRNAs (sgM1 and sgM2) targeting the negative regulator Myostatin (MSTN) gene were designed. The results revealed a 75% editing efficiency of sgM2 at the parthenogenetically activated embryonic level with no detectable off-target effects.

Highly pathogenic avian influenza viruses (HPAIV) persistently threaten wild waterfowl, domestic poultry, and public health. The East Asian-Australasian Flyway plays a crucial role in HPAIV dynamics due to its large populations of migratory waterfowl and poultry. Over recent decades, this flyway has undergone substantial landscape changes, including both losses and gains of waterfowl habitats.
