Smallholder households across rural sub-Saharan Africa often rely on goats to support their livelihoods, food security, and financial security, and as a risk mitigation strategy. Across the region, goat health and performance outcomes vary greatly, and it is often difficult to quantify the impact of the animal health-nutrition nexus on livelihood outcomes. Two socio-economic surveys were conducted to this end in Botswana. Firs...
Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load curves, particularly under conditions of intermittent zero flow, is a critical chall...

Free Falling: Fizzing Wild‐Caught Smallmouth Bass Results in the Inability to Control Buoyancy in Deep WaterNARA Subscribed
Fizzing, a somewhat controversial technique for mitigating barotrauma, uses hollow hypodermic needles to release gas from the swim bladder of fish. To isolate effects of fizzing, 106 smallmouth bass ( Micropterus dolomieu ) were caught from shallow water without barotrauma and tested to determine if they could effectively control their buoyancy after having their swim bladder fizzed or punctured by releasing them over shallow...
Hook removal devices have been developed to enable rapid release of angled fish, yet little research has evaluated their effectiveness and potential for injury among hook types. We compared the performance of hook removal tools and bare hands with four hook types on freshwater Lepomid sunfish. Dehooking performance was assessed using hook removal time, unhooking difficulty, degree of tissue damage at the hooking location, and...
Effects of Recreational Fishing Gear Type on Reflex Impairment and Post‐Release Swimming Activity of Smallmouth BassNARA Subscribed
Recreational anglers have access to a diverse range of rod and line strengths that enable them to choose equipment that can enhance their ability to effectively target and capture specific fish of a given body size. However, anglers may not always select the appropriate gear type for the targeted species. Here, we assessed the effect of gear setup on immediate reflex impairment and short‐term post‐release swimming behavior of...
The nutritional feed gap: Seasonal variations in ruminant nutrition and knowledge gaps in relation to food security in Southern AfricaNARA Subscribed
Livestock production is critical to food security and rural livelihoods across Southern Africa. Despite progress in livestock science research in recent years, the seasonal availability and quality of feed remains one of the key challenges to livestock productivity in Southern Africa. In particular, dry weather conditions, the lack of rain and lower temperatures in the dry season cause herbaceous plants to die back and browse...
Circumpolar and Regional Seascape Drivers of Genomic Variation in a Southern Ocean OctopusNARA Subscribed
Understanding how ecological, environmental and geographic features influence population genetic patterns provides crucial insights into a species' evolutionary history, as well as their vulnerability or resilience under climate change. In the Southern Ocean, population genetic variation is influenced across multiple spatial scales ranging from circum‐Antarctic, which encompasses the entire continent, to regional, with varying...
