“…The negative impact of fence density on gazelle distribution is consistent with those reported for pronghorns in North America, which also avoid areas with greater fence density within their home range (Sheldon ). Unlike Tibetan antelope ( Pantholops hodgsoni ), which cannot cross even low barriers (Fox and Dorji ), we have observed Przewalski's gazelles to jump over, or squeeze through, fences and fence height was not a significant covariate in any of the final models. A single fence may not be an obstacle, but when fence density increases, access of an area to gazelles may be reduced for 2 potential reasons.…”

The impact of fencing on the distribution of Przewalski's gazelle

The endangered Przewalski's gazelle (Procapra przewalskii) experienced severe habitat loss and population decline over the last century. Illegal hunting of gazelles has been largely prevented since 2002, leaving fencing of pastures as one of the main threats to the gazelle. We conducted surveys on 810 km of parallel transects on 8 gazelle‐occupied sites and 4 nearby control sites where no gazelles were found, and evaluated the impact of fencing on gazelle distribution. A comparison of gazelle‐occupied and control sites showed the former had a lower fence density and height, lower aboveground biomass (EVI), and a longer distance to houses. Logistic regression indicated that the presence of gazelle feces on the 1‐km segment of transect was negatively affected by the density of fences and the proportion of fences with barbed wire both in spring and summer. In addition, we found a negative effect from distance to houses in spring and from EVI in summer. Gazelles did not occur more on grasslands with greater vegetation biomass, possibly because of the association of greater vegetation biomass with greater fence density and proportion of barbed wires. Although removing fences can be costly, lowering the top barbed wire, as well as constructing special gates and seasonal use of existing gates, may be beneficial for this endangered species at minimal disruption to local people. © 2014 The Wildlife Society.

“…The state space represented here is meant to depict model outcomes over a wide range of theoretically possible parameter conditions, without implying that all locations in the state space are attainable (e.g., prey rate of movement) or desirable (forager velocity). wait strategies have been replaced with active-search using motorcycles and guns (Fox and Dorji, 2009). It is interesting to note that before the introduction of rapid transportation technology, sit-and-wait hunting in blinds was often the preferred hunting strategy for antelope, deer, and other ungulates, even though intuition would suggest that such animals are typically fast-moving prey items.…”

Sit-and-wait versus active-search hunting: A behavioral ecological model of optimal search mode

We model the behavioral ecology of search mode for randomly moving predator and prey. Active-search is favored at low prey movement velocity, ambush at high prey velocity. Sit-and-wait mode is favored if predator movement is energetically costly. Ambush is favored if faster predator velocity alerts prey or impedes their detection. Optimal predator velocity in active-search mode balances costs against prey movement. a r t i c l e i n f o b s t r a c tDrawing on Skellam's (1958) work on sampling animal populations using transects, we derive a behavioral ecological model of the choice between sit-and-wait and active-search hunting. Using simple, biologically based assumptions about the characteristics of predator and prey, we show how an empirically definable parameter space favoring active-search hunting expands as: (1) the average rate of movement of prey decreases, or (2) the energetic costs of hunter locomotion decline. The same parameter space narrows as: (3) prey skittishness increases as a function of a hunter's velocity, or (4) prey become less detectable as a function of a hunter's velocity. Under either search tactic, encounter rate increases as a function of increasing prey velocity and increasing detection zone radius. Additionally, we investigate the roles of habitat heterogeneity and spatial auto-correlation or grouping of prey on the optimal search mode of a hunter, finding that habitat heterogeneity has the potential to complicate application of the model to some empirical examples, while the effects of prey grouping lead to relatively similar model outcomes. As predicted by the model, the introduction of the horse to the Great Plains and the introduction of the snowmobile to Arctic foraging communities decreased the metabolic costs of active-search and led to a change in normative hunting strategies that favored active-search in place of sit-and-wait hunting.

Desert kites in Jordan – a new appraisal

The desert kites of Jordan, usually stone‐built enclosures with long trailing walls, are part of a broader phenomenon found throughout specific parts of the Middle East, with similar types of structures known widely across the world. Most commonly, the enclosures are used for trapping large herds of ungulates. Those found in Jordan are more densely packed and of much greater variety than those elsewhere in the Middle East. This paper offers a review of the current state of knowledge concerning desert kites in Jordan, including new data on patterns of orientation and recent studies that help to strengthen the case for a Neolithic date for some of the kite systems.
