, 2015
We perform a statistical study of the distances between successive occurrencies of a given dinucleotide in the DNA sequence for a number of organisms of different complexity.

Balancing benefits and burdens: Tourist camps and lion conservation in the Maasai Mara

Conservation Science and Practice, EarlyView.
Wildlife tourism supports conservation and economies, but its rapid expansion can negatively impact ecosystems. Using spatially explicit lion density data from the Maasai Mara (2014–2022), we found that higher densities of tourist camps significantly reduce lion presence, independent of prey or vegetation, and that newly established camps displace ...

Global late Quaternary megafauna extinctions linked to humans, not climate change [PDF]

, 2014
The late Quaternary megafauna extinction was a severe global-scale event. Two factors, climate change and modern humans, have received broad support as the primary drivers, but their absolute and relative importance remains controversial.

Aural plaques: Considerations on autohaemotherapy treatment in four Mangalarga Marchador crossbred horses

Equine Veterinary Education, EarlyView.
Summary The occurrence of Aural Plaques (AP) in horses, attributed to infection with Equus caballus Papillomavirus (EcPV), has become increasingly prevalent in equine breeding populations. Major challenges in managing this condition include genetic susceptibility to the virus, significant variability in individual immune responses among horses and the ...

The proteomic differences and expression of fatty acid‐binding protein 6 (FABP6) associated with gastrointestinal injury in horses with oral administration of a clinical dose of phenylbutazone

Equine Veterinary Journal, EarlyView.
Abstract Background Phenylbutazone (PBZ) can potentially induce gastrointestinal ulceration, and early detection of PBZ‐induced gastroenteropathy will be useful for the diagnosis, treatment, and prevention of PBZ toxicity. Objectives To identify putative proteins associated with equine gastric ulcer syndrome after clinical dose (4.4 mg/kg ...

Tracheal collapse rates in Kenyan working cart and pack donkeys

Equine Veterinary Journal, EarlyView.
Abstract Background Donkeys (Equus asinus) in East Africa are recognised as working with poorly designed harnesses and carts. The donkey cart used in regions of Africa, specifically Meru County, Kenya, appears to place the cart's weight solely on the donkey's mid‐cervical region.

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Equine trypanosomiasis, a systematic review and meta‐analyses: Prevalence, morbidity and mortality

Equine Veterinary Journal, EarlyView.
Abstract Background Equine trypanosomiasis is a neglected protozoal disease. Objectives To perform a systematic search of literature to explore: (1) In equines what is the global geographical distribution and prevalence of trypanosomiasis? In low and middle‐income countries (LMICs) is trypanosomiasis more prevalent than in higher‐income countries (HICs)

Prelude to the Anthropocene: Two new North American Land Mammal Ages (NALMAs) [PDF]

, 2014
Human impacts have left and are leaving distinctive imprints in the geological record. Here we show that in North America, the human-caused changes evident in the mammalian fossil record since c.
