“…In Mojave, kit foxes were the most photographed carnivore at water developments and one of the most commonly photographed mammals [21]. The intensity of visitation to water developments by kit foxes in Mojave indicates that arid-adapted species may use water developments more frequently than previously believed [50].…”

Water Developments and Canids in Two North American Deserts: A Test of the Indirect Effect of Water Hypothesis

Anthropogenic modifications to landscapes intended to benefit wildlife may negatively influence wildlife communities. Anthropogenic provisioning of free water (water developments) to enhance abundance and distribution of wildlife is a common management practice in arid regions where water is limiting. Despite the long-term and widespread use of water developments, little is known about how they influence native species. Water developments may negatively influence arid-adapted species (e.g., kit fox, Vulpes macrotis) by enabling water-dependent competitors (e.g., coyote, Canis latrans) to expand distribution in arid landscapes (i.e., indirect effect of water hypothesis). We tested the two predictions of the indirect effect of water hypothesis (i.e., coyotes will visit areas with free water more frequently and kit foxes will spatially and temporally avoid coyotes) and evaluated relative use of free water by canids in the Great Basin and Mojave Deserts from 2010 to 2012. We established scent stations in areas with (wet) and without (dry) free water and monitored visitation by canids to these sites and visitation to water sources using infrared-triggered cameras. There was no difference in the proportions of visits to scent stations in wet or dry areas by coyotes or kit foxes at either study area. We did not detect spatial (no negative correlation between visits to scent stations) or temporal (no difference between times when stations were visited) segregation between coyotes and kit foxes. Visitation to water sources was not different for coyotes between study areas, but kit foxes visited water sources more in Mojave than Great Basin. Our results did not support the indirect effect of water hypothesis in the Great Basin or Mojave Deserts for these two canids.

“…Whether large mammals in desert ecosystems can meet water requirements with preformed or metabolic water during all seasons is unclear, but is unlikely in the hot, dry season (Mogart et al, 2005;Cain et al, 2006;Larsen et al, 2012). Turner (1973) noted that if the water content of forage consumed by desert bighorn sheep was sufficiently high, those ruminants could meet their exogenous water needs with preformed water in their food; such is the case during winter.…”

“…Certainly, tradeoffs associated with forage quality and water content have been documented in desert ungulates. Sonoran pronghorn were reported to select forage with high preformed water content but of low nutritional value when availability of water was low, with the overall effect of lowered population performance and high adult mortality (Fox et al, 2000;Mogart et al, 2005).…”

“…Los patrones de actividad, el desplazamiento y el uso del hábitat en varios mamíferos son influenciados por la variación espacial y temporal de la disponibilidad del agua (Rautenstrauch y Krausman 1989; Mandujano y Gallina 1995, Morgart et al 2005;Marshal et al 2006;Briceño-Méndez et al 2014).

Water holes formed by precipitation in Calakmul region southern Mexico are of high importance for the conservation of many endangered species, such is the case of the Central American Tapir (Tapirus bairdii). These water holes locally named "aguadas" are the only source of water for wildlife in the dry season. The purpose of this study was to estimate the relative abundance and the use of these "aguadas" by Tapirus bairdii in two sites with different conditions: the Calakmul Biosphere Reserve (RBC) a protected area, and the ejido Nuevo Becal (NB) a perturbed site where hunting and other non-timber resources extraction take place. It is expected that in RBC the relative abundance of tapirs and the use of the water holes are higher than in NB. Camera traps were set in nine water holes in NB and nine in RBC in 2014. In addition, in RBC six water holes were monitored since December 2012 until 2013. The relative abundance was calculated as the number of independent photographs divided by the sampling effort per 1,000 traps / night. For the use of water holes analysis, the variables evaluated were: latency (the lapse of time for the tapirs to return to a water hole) and the visit frequency per month. We compare the use of the water holes between seasons and between sites. Relative abundance of tapirs in 2014 was of 37.0 and 6.2 registers/1,000 camera-traps in NB and RBC, respectively (sampling effort: 2,268 days per site). The water holes in NB were significantly more visited than the ones in the RBC (P < 0.05). The latency time was of 9.6 days in NB, and 10.8 days in RBC during the dry season, and 39.0 days in NB and 38.5 days in RBC during the wet season. The water holes were visited 1.8 times in NB and 0.3 times in RBC per month in the dry season, and 0.37 times in NB and 0.16 times in RBC in the rainy season. The fact of finding a higher abundance of tapirs in a place where antropogenic perturbation exists and with a higher abundance of water, indicated that water bodies are one of the most important attribute for the conservation of tapirs' population in the region of Calakmul. Moreover, the high index of relative abundance found in an area where human perturbation exists, means that human activities in places where tapir is not hunted, does not have a significant detrimental effect in the tapir´s populations. Therefore, the ejido NB is highlighted as a priority area for the conservation of the Centroamerican tapir in Mexico.En la región de Calakmul en el sur de México, las aguadas (cuerpos de agua formados por la precipitación) son de gran importancia para la conservación de muchas especies que se encuentran en peligro de extinción, como el tapir centroamericano (Tapirus bairdii). Estos reservorios constituyen la única fuente de agua para la fauna silvestre durante la estación seca. Los objetivos de este estudio fueron: estimar la abundancia relativa del tapir y la intensidad de uso de las aguadas por Tapirus bairdii en en dos sitios contrastantes en cuanto a su disponibilidad de agua, la Reserva de la Biosfera ...
