“…Specimens of L. altamirae have not been collected in more than 100 years and this species may have suffered a reduction in distribution similar to or greater than experienced by L. flavigularis (Lorenzo et al, 2008) and L. callotis, the latter species having been replaced over much of its range by L. californicus (Anderson, 1972;Brown et al, 2018).…”

“…The increase of human settlements, the bad land management, and lack of control of productive activities, such as extensive ranching and the burning of pastures for seasonal agriculture have resulted in habitat loss and fragmentation in the study area (Lorenzo et al, 2008;Rioja et al, 2011;Carrillo-Reyes et al, 2012). Although porcupines are not hunted, their habitat (semi-deciduous forest and palms and tropical dry forest) is disappearing at an accelerated rate due to excessive logging to expand the sorghum planting land area (J.…”

Abstract:Land use changes by human activities have been the main causes of habitats and wildlife population degradation. In the Tehuantepec Isthmus in Oaxaca, the tropical habitat of the porcupine Sphiggurus mexicanus has been subject to vegetation and land use changes, causing its reduction and fragmentation. In this study, we estimated vegetation cover and land use (d n ) change rates and assessed habitat availability and potential corridors for possible porcupine movements to avoid its isolation. In the study area, the type of vegetation with the most change rate value was the savanna (d n =-2.9), transformed into induced grasslands. Additionally, we have observed the porcupine (since 2011) in semi-deciduous (d n =-0.87) and tropical dry (d n =-0.89) forests that have been transformed in temporal agriculture and mesquite and induced grasslands. The vegetation inhabited by the porcupine resulted in recording a total of 64 plant species (44 trees, nine vines, seven herbs, four shrubs), of which the vine Bunchosia lanceolata showed the highest importance value (41.85) followed by the trees Guazuma ulmifolia (22.71), Dalbergia glabra (18.05), and Enterolobium cyclocarpum (17.02). The habitat evaluation and potential corridor analysis showed that only 1 501.93ha could be considered as suitable habitats with optimum structural conditions (coverage, surface, and distances to transformed areas) to maintain viable populations of S. mexicanus, and 293.6ha as corridors. An increasing destruction of the porcupines' habitat has been observed in the study area due to excessive logging, and actions for this species and its habitat conservation and management have to be taken urgently.

Epub 2014 December 01.Key words: Sphiggurus mexicanus, corridors, habitat availability, selection, Tehuantepec Isthmus, tropical porcupines, use, plant associations.The tropical forest ecosystems are strategically important areas because of the great species diversity they harbor, and the environmental services they offer (soil stabilization and potential for carbon capture, water cycle, and climate regulation). Unfortunately, they are the most deforested; it has been documented that 650 000ha of tropical forest in Mexico are lost each year, and about 2% have been lost annually since the beginning of the eighties (Galicia et al., 2007). Mexico has 104 023km 2 of tropical forests, and the Tehuantepec Isthmus in the State of Oaxaca has approximately 12 163.5km 2 of tropical forests (INEGI, 2012), which is historically a region of anthropogenic use (Gómez-Martínez, 2005). The main causes of destruction of vast areas of forests and arid zones in the Tehuantepec Isthmus are due to changes in land use because of agricultural activities and forest fires (González et al., 2004;INEGI, 2005).Despite the ecological and economic importance of forest ecosystems, a monitoring system of land use changes, its causes, explanations, and predictions is not available (Galicia et al., 2007). It is essential to carry out studies ...

“…Rioja et al (2008) recently reported that the Tehuantepec jackrabbit has a polygamous mating behavior in which a male mate with several females. It is likely that, due to a higher population density found in our study area than for other populations, males of Santa María del Mar need to travel shorter distances to fi nd mates, an assumption supported by information on population density: Santa María del Mar is the Tehuantepec jackrabbit population with the highest density values ever recorded for this species (12 ind/km 2 ; Vargas 2000), while other populations range from 0.76 to 9.5 ind/km 2 at Montecillo Santa Cruz, and 8.9 ind/km 2 at San Francisco del Mar (Sántiz, 2002;Sántiz, 2005;Lorenzo et al, 2008). Nelson (1995) found that at high densities of females, M. agtestis males have smaller home ranges than they do at lower female densities.…”

Information on the spatial ecology of the Tehuantepec jackrabbit (Lepus fl avigularis) is important for developing management strategies to preserve it in its habitat. We radio-collared and monitored 60 jackrabbits from May 2006 to April 2008. We estimated annual and seasonal home ranges and core areas by using the fi xed-kernel isopleth to 95% and 50% of confi dence, respectively. This jackrabbit showed a highly variable seasonal home range: 1.13 ha to 152.61 ha for females and 0.20 ha to 71.87 ha for males. Annual and seasonal home ranges and core areas of females were signifi cantly wider than male home ranges. There was considerable overlap of ranges within and between sexes, with the home range of each jackrabbit overlapping with the ranges of 1 to 46 other individuals. Home range and overlap analysis confi rms that the Tehuantepec jackrabbit is a polygamous and non-territorial species. Conservation of savannas and grassy dunes is indispensable to assure the survival of the species.
