“…Small reptiles and invertebrates would be differentially affected by water point-centered, trampling-induced disturbances because habitat alteration occurs at scales much smaller than that of piospheres, but at a scale that corresponds to the body size and therefore home range of these organisms (e.g. Jackson et al, 2002;Whitehouse et al, 2002). Changes in animal populations could arise from reductions in the cover of grasses, or reductions in soil surface roughness or litter depth, which are known to affect small reptile populations (James, 2003).…”

“…The categories were: disturbance by ants, ejecta including all soil discharged by digging or foraging, foraging including all pits dug by rodents, rodent burrows, and termite constructed galleries and sheeting. Detailed descriptions of biopedoturbation types, the species which produce them and their biological feedbacks are in Jackson et al (2003). Data were collected during the months of March, May, July, September and November.…”

“…The CHD is influenced by severe natural and anthropogenic disturbances (Table S6). Livestock practices have replaced significant portions of the native vegetation and cattle ranching have damaged the area with several cycles of sheepherding, which exerts major stress on physiologically sensitive bushes and pasturelands (Jackson et al 2003). The loss of river streams and increase in flooding due to dam construction has impacted wildlife dynamics and reduced suitable habitat.…”

An assessment of natural and human disturbance effects on Mexican ecosystems: current trends and research gaps

Mexico harbors more than 10% of the planet's endemic species. However, the integrity and biodiversity of many ecosystems is experiencing rapid transformation under the influence of a wide array of human and natural disturbances. In order to disentangle the effects of human and natural disturbance regimes at different spatial and temporal scales, we selected six terrestrial (temperate montane forests, montane cloud forests, tropical rain forests, tropical semi-deciduous forests, tropical dry forests, and deserts) and four aquatic (coral reefs, mangrove forests, kelp forests and saline lakes) ecosystems. We used semiquantitative statistical methods to assess (1) the most important agents of disturbance Electronic supplementary material The online version of this article (affecting the ecosystems, (2) the vulnerability of each ecosystem to anthropogenic and natural disturbance, and (3) the differences in ecosystem disturbance regimes and their resilience. Our analysis indicates a significant variation in ecological responses, recovery capacity, and resilience among ecosystems. The constant and widespread presence of human impacts on both terrestrial and aquatic ecosystems is reflected either in reduced area coverage for most systems, or reduced productivity and biodiversity, particularly in the case of fragile ecosystems (e.g., rain forests, coral reefs). In all cases, the interaction between historical human impacts and episodic high intensity natural disturbance (e.g., hurricanes, fires) has triggered a reduction in species diversity and induced significant changes in habitat distribution or species dominance. The lack of monitoring programs assessing before/after effects of major disturbances in Mexico is one of the major limitations to quantifying the commonalities and differences of disturbance effects on ecosystem properties.
