“…The Bell hacienda was divided in the late 1960s, forming several private ranches and the ejido of San Juan de Michis. Contemporary livestock numbers are somewhat lower, but grazing has been identified as a contemporary management problem in buffer zones of the reserve ( Galindo‐Leal et al 1993). Gallina et al (1978) compared photographs of forest openings in the dry and wet seasons, showing that the herbaceous biomass produced in summer was absent by the following spring.…”

The ability of reserves to maintain natural ecosystem processes such as fire disturbance regimes is central to long‐term conservation. Fire‐scarred tree samples were used to reconstruct fire regimes at five study sites totaling approximately 230 ha in pine ( Pinus spp.) and oak (Quercus spp.) forests of La Michilía Biosphere Reserve on the dry east slope of the Sierra Madre Occidental, Durango, Mexico. Study sites covered a 20‐km environmental gradient of elevation, topography, and human land uses. Plant communities ranged from oak‐pine to mixed conifer forests. Fires were frequent at all sites prior to 1930, when large‐scale grazing of domestic livestock was initiated. Widespread fires have been excluded from four of the five sites since 1945, with an essentially uninterrupted regime of frequent fires continuing only in the reserve core. Xeric sites had many, smaller fires, whereas mesic sites had fewer but larger fires. On a reserve‐wide scale, a fire burned on at least one site nearly every year, usually in the dry spring or early summer season, but fire years were rarely synchronous among the sites. Fire occurrence was weakly related to the Southern Oscillation climate pattern; major reserve‐wide fire years almost never coincided with wet Southern Oscillation extremes but only occasionally matched dry extremes. Maintenance of the long‐term frequent‐fire regime in the reserve core is one indicator that the biosphere reserve model has been successful in conserving natural processes, but the protected area is small ( 7000 ha). Because of the key role of frequent‐fire regimes in regulating ecosystem structure and function, restoration of the ecological role of fire disturbance is a desirable conservation strategy.

“…Particularly, only 5.5 % of the reports were greater than 15 deer/km 2 . In a previous study, Galindo-Leal (1993) reported that 51 % of the estimates analyzed were less than 10 deer/km 2 ; finding low variation between habitat types. Population density and biomass could vary depending on climatic factors such as the rain pattern and temperature (Mandujano and Naranjo 2010;Yáñez-Arenas et al 2012a), ecological variables such as vegetation type, topographic features, and human factors such as habitat transformation, presence of livestock and illegal hunting (López-Téllez et al 2007;Coronel-Arellano et al 2008;Ramos-Robles et al 2013).…”

“…The estimations of white-tailed deer densities in the template forest are variable in the different regions. For example, at La Michilía in Durango (Galindo-Leal et al 1993;Gallina 1994) (Mandujano et al 2016b. In these tropical regions, the estimations have been obtained principally through indirect methods such as counts of tracks in dirt roads (Mandujano 2005), and the pellet-groups (Camargo and Mandujano 2011) counts and data suggest that this type of habitat has a higher potential for deer production (Mandujano 2007(Mandujano , 2010.…”

“…The white-tailed deer Odocoileus virginianus is a highly ecological and economically-valued species (Ortega-S. et al 2011), and is the most studied deer species in México (Mandujano 2004). Published books on this deer species have been generated in the northeast region dominated by semiarid scrubs lands (Villarreal-González 1999;Ramírez-Lozano 2004;Fulbright and Ortega-S. 2006), in temperate forests in the Sierra Madre Occidental in Durango (Folliot and Gal-lina 1981;Galindo-Leal and Weber 1997), the region of central México in the Mixteca Poblana (Villarreal-Espino 2006), and in Oaxaca (Mandujano 2016). Monographs have also been published on the natural history of this species in México and Latin America (Méndez 1984;Gallina et al 2010;Ortega-S. et al 2011;Mandujano et al 2014;Gallina et al 2019).…”

The white-tailed deer Odocoileus virginianus is the wildlife species with the greatest geographic distribution and economic importance in Mexico. This article presents a biogeographic analysis of the population density of this deer species by federal states, vegetation types, biogeographic provinces, and field methods, based on 200 selected studies. Estimates are highly variable and potentially biased due to the different field designs and statistical analyses. The national average density was estimated at 6.9 deer/km2 (SD = 5.1); specifically, 75.5 % of the estimates were less than 10 deer/km2, and only 5.5 % were greater than 15 deer/km2. The highest densities were obtained in the northern region by applying the strip transect counts; while estimations using the fecal group count method were more variable and were the most used method in temperate and tropical dry forest regions. The states with the highest densities were Coahuila, Tamaulipas, Jalisco, Morelos, Michoacán, and Durango. The highest densities were estimated in the xerophilous scrublands of the northeast, intermediate for temperate, tropical dry, and sub-deciduous forests; and the lowest in the tropical wet forest. The highest densities were reported for the Tamaulipeca province followed by the Altiplano Chihuahuense, Sierra Madre Occidental, Costa Pacífica, and Depresión del Balsas. The results of this analysis could guide management strategies for the conservation and sustainable use of this species in extensive UMAs and ANPs, and also to test ecological hypotheses. However, applying more rigorous field design and statistical analysis is important to obtain confident estimates of population density and other demographic parameters to monitor population dynamics.

“…Our response variable to establish habitat use is based on fecal pellet-group counts in transects which were placed in different vegetation communities (Cransac & Hewison 1997, Galindo et al 1993, Guillet et al 1995, Harkonen & Heikkila 1999, Hemami et al 2004, Hernandez et al 1998, Homolka & Matous 1999, Kearney & Gilbert 1976, Koenen & Krausman 2002, Lawes & Nanni 1993, Loft & Kie 1988, McCorquodale 1987, Morellet et al 1996, Ogurlu 1996, Palmer & Truscott 2003, Rollins et al 1984, Secord et al 1999, Suring & Vohs 1979, Takatsuki 1991, Weckerly & Ricca 2000, Welch et al 1990, Zejda & Homolka 1980). The fecal pellet-group counts were carried out during Autumn and Winter, because of declining food resources in cold seasons.…”

RESUMENComo una especie amenazada, las poblaciones de gacela Iraní han disminuido durante las décadas pasadas. El conocimiento de la ecología de la gacela que incluye sus hábitos alimentarios y las asociaciones del habitat que utiliza son centrales para cualquier tipo de esfuerzo de conservación. La ecología de gacelas es pobremente conocida y las asociaciones del habitat de ésta y otras especies de gacelas no se han estudiado en Irán. La gacela Iraní en el habitat de 6000 ha (en el Parque Nacional de Bamoo ) se estudió durante el periodo de Otoño e Invierno. El uso del habitat fue relacionado con las comunidades de vegetación y su composición, por medio del conteo de los grupos fecales cada dos meses: de septiembre/ octubre 2004 a marzo/abril 2005, en 15 transectos permanentes de 2.5 x 200 metros que se localizaron al azar. La densidad de los grupos fecales fue muy similar en cuatro comunidades vegetales, mientras en la comunidad vegetal 1 en la que Scariola orientalis era dominante, fue significativamente menor. La densidad de gacelas está positivamente asociada con tres especies de arbustos (especie: Astragalus spp., Ebenus stellata , Achillea eriophora con P <0.01, P <0.05, P<0.05, respectivamente) y dos especies de pasto (Poa bulbosa y Aegilops umbellulata, P <0.05) y negativamente asociada con Helichrysum leucocephalum (P <0.01), Scariola orientalis (P <0.01) y Centaurea virgata (P <0.01). Las observaciones acerca de la conducta alimentaria mostraron que las gacelas consumían Bromus danthoniae y Stipa barbata durante el otoño y Astragalus spp., Poa bulbosa, Aegilops umbellulata y Bromus danthoniae durante el invierno. Palabras Clave: Uso del habitat, gacela Iraní, hábitos alimentarios, Parque Nacional de Bamoo . ABSTRACTAs a threatened species populations of Persian gazelle have been declining within the country over the last few decades. The knowledge of gazelle ecology including their feeding habits and habitat associations is central to any kind of conservation effort. The ecology of gazelles in Iran is poorly known and habitat associations of this or other species of gazelles have not been studied in Iran. Habitat use by Persian gazelle was studied over autumn-winter period in its 6000 ha habitat in Bamoo National Park. Habitat use was related to plant communities and vegetation composition by clearance transect pellet group counts carried out every 2 months from September/October 2004 to March/April 2005 using 15 randomly placed 2.5 x 200 m permanent transects. The density of pellet groups was similar in 4 out of 5 Nowzari et al.:Habitad use by persian gazelle 110 plant communities, while in plant community 1, in which Scariola orientalis was the dominant species, it was significantly lower. The density of gazelles was positively associated with three species of bushes (Astragalus spp., Ebenus stellata, Achillea eriophora, P<0.01, P<0.05, P<0.05 respectively) and two species of grass (Poa bulbosa and Aegilops umbellulata, P<0.05) and negatively associated with trichomic Helichrysum leucocephalum (P<0....
