Cape lions were genetically diverse prior to extinction, researchers find
Cape lions used to roam the Cape Flats grassland plains of South Africa, in what is now known as Western Cape Providence. When Europeans arrived in South Africa in the mid-1600s, Cape lions, along with many other African carnivores and herbivores, we.....»»
Female mosquitoes rely on one another to choose the best breeding sites, and they"re already on the hunt
Aedes aegypti mosquitoes, one of the most common species in the U.S., love everything about humans. They love our body heat and odors, which enable them to find us. They love to feed on our blood to make their eggs mature. They even love all the stan.....»»

Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences (VMBS) collaborated with Australian geneticists to determine whether the country's population of Timor ponies are genetically diverse enough to support a designated bree.....»»
High-resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter.....»»
Rope entanglement found to be a cause of low breeding rates in right whales

The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers at the University of Bristol and Stellenbosch University in South Africa have found......»»
Migration of hominins out of Africa may have been driven by the first major glaciation of the Pleistocene
A pair of planetary scientists, one with the University of Milan, the other with Columbia University, has found evidence that the exodus of hominins out of Africa approximately 1 million years ago may have been driven by the first major glaciation of.....»»
East Africa must prepare for more extreme rainfall during the short rainy season, says study

Early experiments show Ebola-fighting potential of engineered bacteria
Since its 1976 emergence in Africa, the Ebola virus has proven an especially lethal contagion, killing roughly 50% of the people who contract it. The 2019 FDA approval of a vaccine, combined with the subsequent development of two antibody-based drugs.....»»
Integrating non-additive GWAS with historical dissemination to illuminate nut traits and blooming time in almonds
Modern breeding focuses on genetic analyses and germplasm management and dominates in altering crop genomes, but often neglects non-additive genetic effects that are essential for understanding traits. Almond [Prunus dulcis Miller (D.A. Webb)] has si.....»»

Enhancing sweet cherry breeding: Insights from genotyping-by-sequencing and genome-wide association studies
Sweet cherry (Prunus avium L.) is one of the most economically important perennial fruit species growing in temperate regions. However, partly due to climate change and biological pressures from pathogens, sweet cherry production in France has been d.....»»
Honey bees are surprisingly abundant, research shows—but most are wild, not managed in hives
There are roughly 100 million managed western honey bee (Apis mellifera) colonies in hives worldwide, with about half in Europe, Africa and western Asia, where the species is native, and the rest in the Americas, Oceania and eastern Asia, where it is.....»»
