This paper utilizes economic valuation to offer a new perspective on livestock rancher-predator conflicts. While most studies have considered losses to the species directly involved, i.e., cattle and wolves (Canis lupus), we take into account other species that are threatened by efforts to protect livestock. In this case, vultures (Gyps fulvus) and gazelles (Gazella gazella), both endangered sp...

The male and the tritonymph of Ioanella mimon are described for the first time parasitizing to Mimon cozumelae from Yucatan, Mexico. Male of Ioanella mimon is characterized by the presence of legs I with the tibia and tarsus fused forming a small complex devoided of apical claws, legs II-IV with two claws, setae vi at level of anterior end of genital plate, genital plate rounded with an anterio...

This study was conducted at the Bukhara breeding centre (Ouzbekistan, Central Asia) on Persian gazelles (Gazella subgutturosa subgutturosa) and at Thumammah (Saudi Arabia) on sand gazelles (Gazella subgutturosa marica). Plasma prolactin (PRL) and progesterone were determined in groups of females. Because these females were under two different photoperiods (20 degrees N in Saudi Arabia and 40 de...

Selective brain cooling is a thermoregulatory effector proposed to conserve body water and, as such, may help artiodactyls cope with aridity. We measured brain and carotid blood temperature, using implanted data loggers, in five Arabian oryx (Oryx leucoryx) in the desert of Saudi Arabia. On average, brain temperature was 0.24±0.05°C lower than carotid blood temperature for four oryx in April. S...

Understanding the behavioral adaptations and subsistence strategies of Middle Paleolithic humans is critical in the debate over the evolution and manifestations of modern human behavior. The study of faunal remains plays a central role in this context. Until now, the majority of Levantine archaeofaunal evidence was derived from late Middle Paleolithic sites. The discovery of faunal remains from...

We carried out a detailed taphonomic study of the faunal remains from Nahal Hadera V (NHV), a large Kebaran open-air site on the northern coastal plain, Israel. Faunal remains were previously identified to bone element and species (Saxon, Martin & Bar-Yosef, 1978). However, NISP and MNI values were calculated based on teeth and epiphyses only. In this study we identified the maximum number of s...

Herbivores are major drivers of ecosystem structure, diversity, and function. Resilient ecosystems therefore require viable herbivore populations in a sustainable balance with environmental resource availability. This balance is becoming harder to achieve, with increasingly threatened species reliant on small protected areas in increasingly harsh and unpredictable environments. Arid environment...
