Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris , across sympatric (Essequibo River) and allopatric (Rupununi and Rewa Rivers) populations in Guyana – visual...

Background and aims In mesic areas of Sub-Saharan Africa, grassland and soil degradation is widespread and accelerating through overgrazing, alien plant encroachment, and climate change. Selection of native plant species that help to regenerate soil fertility is needed. Here we used a plant functional trait-based approach to species selection aiming to identify traits of native grassland plants that may regenerate soil fertili...

Effective management of COVID-19 requires clinical tools to treat the disease in addition to preventive vaccines. Several recombinant mAbs and their cocktails have been developed to treat COVID-19 but these have limitations. Here, we evaluate small ankyrin repeat proteins called Ankyrons that were generated to bind with high affinity to the SARS-CoV-2 virus. Ankyrons are ankyrin repeat proteins comprised of repetitions a struc...
