Genetic identification of gastrointestinal parasites in the world's most endangered ungulate, the hirola (Beatragus hunteri)

open access: yesVeterinary Record, Volume 196, Issue 12, 21/28 June 2025.
Abstract Background The hirola (Beatragus hunteri) is the world's most critically endangered antelope. Its parasitic fauna has never been genetically characterised, raising questions about its possible role in the species' population decline. This study aimed to assess the presence of gastrointestinal parasites in hirolas and their transmission ...

Is the American Zebu really Bos indicus?

open access: yesGenetics and Molecular Biology, 1999
The American continent was colonized in the 16th century by Europeans who first introduced cattle of Bos taurus origin. Accounts register introduction of Bos indicus cattle into South America in the 19th and continuing through the 20th century, and most ...

Grazing Affects Soil Organic Carbon Stocks Directly and Indirectly Through Herbaceous Species Diversity in Sahelian Savanna Ecosystems

open access: yesLand Degradation &Development, Volume 36, Issue 10, Page 3490-3498, June 2025.
ABSTRACT The impact of livestock grazing on soil organic carbon (SOC) stocks in the Sahel has been poorly documented due to a lack of data from different grazing intensities. This study evaluated SOC stocks under four grazing intensities within 0–30 cm soil depth in dry savanna ecosystems of Senegal.

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population

open access: yesGenetics and Molecular Biology, 2005
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2

The Lost Large Mammals of Arabia

open access: yesJournal of Biogeography, Volume 52, Issue 6, June 2025.
ABSTRACT Aim If successful, plans to restore the vegetation of the Arabian Peninsula (AP) as announced by the Middle East and Saudi Green Initiatives will see the greatest increase in vegetation cover since the beginning of the Holocene Humid Phase (HHP), roughly 9–10,000 years ago.

Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations

open access: yesGenetics and Molecular Biology, 2005
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in ...

Zebra Risk Perception in a Landscape of Fear

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We examined how zebras (Equus quagga) in northern Tanzania respond to predation risk from lions (Panthera leo) and humans using behavioral observations, lion roar playbacks, and flight initiation distance (FID) assays. Vigilance decreased with group size and central herd positioning, while FID increased with heterospecific associations, but neither was

Carcass Characteristics, Chemical Composition and Fatty Acid Profile of the Longissimus Muscle of Bulls (Bos taurus indicus vs. Bos taurus taurus) Finished in Pasture Systems

open access: yes, 2008
This experiment was carried out to evaluate the carcass characteristics, chemical composition and fatty acid profile of the Longissimus muscle (LM) of three cattle genetic groups (Puruna, PUR, 11; 1/2 Puruna vs.
