Indigenous cattle account for approximately 80% of Uganda’s cattle population. These animals are well adapted to the country’s ten agroecological zones and are mainly kept under pastoral and agropastoral systems. Unlike commercial breeds, they thrive on low-quality feeds, while tolerating major tropical diseases and parasites including tsetse flies, ticks, and vector-borne infections. Whole-genome sequence (WGS) analysis offer...

Efforts have been underway over 40 years to reduce nutrient pollution of the Chesapeake Bay, USA, in one of the world’s most sustained and studied campaigns to abate coastal eutrophication. Nitrogen and phosphorus loads have been reduced predominantly from advanced wastewater treatment and diminished atmospheric deposition of nitrogen. Reductions from nonpoint sources, including agricultural activities and stormwater, continue...

Species interactions among multiple invasive species can present hidden challenges for management and eradication efforts. Bighead and Silver carp ( Hypophthalmichthys nobilis and H. molitrix , respectively) are closely related species that have co-invaded the Mississippi River and many of its tributaries, including the Illinois River. We used a combination of causal inference and dynamic models to test for interspecific inter...

The Kulanaokuaiki Tephra Unit 3 (900 C.E.) was a subplinian basaltic scoria eruption, the largest known to have occurred at Kīlauea’s summit. The initiation mechanism and cause(s) of this highly hazardous eruption remain poorly understood, particularly as this style of activity has not been observed in the modern period. We use olivine diffusion timescales from Fe-Mg and lithium zoning to assess magma storage timescales and ev...

Co-production is increasingly recognized as a transformative approach to addressing environmental and societal challenges; however, key questions remain about how academic and Indigenous partnerships adapt and endure. Existing co-production frameworks offer insights on how to establish new relationships and suggest that long-term partnership may be key to climate adaptation efforts, yet few studies report on the application of...

Guyana, and the Guianas more generally, exhibit some of the highest examples of biodiversity and regional endemism in the Neotropics. However, much of this diversity is still unknown, with the first modern list of freshwater fishes from Guyana compiled only in 2022. We continue to build on prior efforts in Guyana and provide an annotated list of fishes collected from the Canje River, a lowland tributary of the Berbice River. T...

Coenzyme Q10 (CoQ 10 ) is an integral component of the mitochondrial electron transfer system. Most studies have administered the oxidised form of CoQ 10 (ubiquinone) and observed no effects on mitochondrial respiratory function or endurance exercise performance. The reduced form of CoQ 10 , ubiquinol (UQH 2 ), has greater bioavailability than ubiquinone, but the effects of UQH 2 supplementation on mitochondrial respiratory fu...
