Recovery of the Florida panther (Puma concolor coryi) depends on habitat conservation on private rangelands. However, cattlemen-panther conflicts and lack of trust in wildlife agencies is undermining panther conservation efforts.
In a greenhouse study, the effects of vermicompost and arbuscular mycorrhizal fungi (AM fungi) bio fertilizers on soil properties and Medicago polymorpha growth were studied. The experiment was set up in a completely randomized design in a factorial layout with five replications. The vemicompost treatment was applied in six different levels, including 0, 15, 30, 45, 60 and 75% fertilizer.
In a study of the traditional livelihoods of 12 Monpa and Brokpa villages in Arunachal Pradesh, India using social–ecological and participatory rural appraisal techniques, we found that the forest tree species paisang (Quercus griffithii, a species of oak) is vital to agroecosystem sustainability.
A number of previous studies have emphasized the determinants of land-use change, as well as the management of communal lands in the pastoral systems, without assessing the effects of such changes on pastoralists/agro-pastoralists’ food security.
CONTEXT: Grasshoppers are a dominant herbivore assemblage globally and play an important role for ecosystem nutrient cycling. Yet, we lack a strong understanding of the relationship between grasshopper diversity and plant community composition at the landscape scale. OBJECTIVE: Our aim was to test landscape scale relationships between plant and grasshopper communities.
An estimated 110 Mt of dust is eroded by wind from the Australian land surface each year, most of which originates from the arid and semi-arid rangelands. Livestock production is thought to increase the susceptibility of the rangelands to wind erosion by reducing vegetation cover and modifying surface soil stability.
Previous studies in drylands have shown that while gender roles are becoming more flexible, privatization and formalization of land tenure tends to marginalize women in drylands while environmental degradation leads to differential changes in gender workload.
QUESTION: Increasing population pressure, socio‐economic development and associated natural resource use in savannas are resulting in large‐scale land cover changes, which can be mapped using remote sensing.
Desertification is an escalating concern in global drylands, yet assessments to guide management and policy responses are limited by ambiguity concerning what this term means and what processes are involved. In order to provide greater clarity, we propose that desertification assessments be placed within a state change-land use change (SC-LUC) framework.
CONTEXT: In addition to biodiversity conservation, California rangelands generate multiple ecosystem services including livestock production, drinking and irrigation water, and carbon sequestration. California rangeland ecosystems have experienced substantial conversion to residential land use and more intensive agriculture.
We present quantitative reconstructions of regional vegetation cover in north‐western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k calendar years before present (bp)] at a 1° × 1° spatial scale with the objective of producing vegetation descriptions suitable for climate modelling.
Soil erosion by water is considered a major cause for land degradation in Jordan, where 0.14 cm of productive top soil is eroded annually. This investigation is intended to estimate the annual soil loss in Wadi Kerak watershed, and to examine the spatial patterns of soil loss and intensity, as an essential procedure for proper planning of conservation measures.
