Contrasting effects of pine plantations on two skinks: results from a large‐scale ‘natural experiment’ in Australia

Journal Articles & Books

The conversion of agricultural land to forest plantations is a major driver of global land‐use change, and considering that large portions of the planet are covered by forest plantations, understanding their impact on biodiversity is a research priority. The aim of our study was to quantify the long‐term response of two lizard species to the transformation of the matrix surrounding remnant habitat patches (from agricultural land to pine plantations).

The western prairie fringed-orchid is a rare North American orchid restricted to a few remnants of wet to mesic tallgrass prairie. It is federally listed in both Canada and the United States and both countries have developed a recovery plan for the species. Two key management objectives are to monitor population trends and identify beneficial management practices. We used 21 y of data from the Manitoba metapopulation to assess effects of weather and land management on this species. Our results suggest the metapopulation in Manitoba is relatively stable.

Northern Great Basin: A Region of Continual Change

Journal Articles & Books
Décembre, 2015

There are many controversies and conflicts surrounding land management in the Great Basin. The conflicts often revolve around the maintenance of native plant and animal communities. This paper outlines some of the historical aspects of plant community change and some of the unanticipated impacts of policies applied to the Great Basin during Euro-American exploration and settlement. This narrative provides readers with some background on the turbulent history of the Great Basin, and suggests the need for a coordinated vision for future Great Basin land management.

The enclosure system is an increasingly popular approach for land rehabilitation among communities inhabiting the arid and semi-arid lands in Africa. However, the mixed results associated with its adoption by households call for an in-depth understanding of the management regimes.

Land Change in Eastern Mediterranean Wood-Pasture Landscapes: The Case of Deciduous Oak Woodlands in Lesvos (Greece)

In Mediterranean Europe, wood-pasture landscapes with oak woodlands as emblematic ecosystems are undergoing rapid land-use change, which may threaten their legacy as hotspots of biodiversity, ecosystem services, and cultural heritage. The objective of this study was to quantify land cover changes and transitions as well as the dynamics of oak woodland patterns and densities over 50 years in two municipalities at the center and edges of Quercus macrolepis distribution in Northern Lesvos (Greece).

BACKGROUND AND AIMS: The Karoo biomes of South Africa are major feed resources for livestock farming, yet soil nutrient depletion and degradation is a major problem. The objective of this study was to assess impacts of long-term (>75 years) grazing during spring (SPG), summer (SUG), winter (WG) and exclosure (non-grazed control) treatments on soil nutrients, penetration resistance and infiltration tests.

Evaluating pasture and soil allowance of manganese for Kajli rams grazing in semi-arid environment

Journal Articles & Books
Décembre, 2015

The current research on the manganese (Mn) transfer from soil to plant as well as to grazing Kajli rams in the form of sampling periods was carried out under semi-arid environmental conditions. Forage, soil and blood plasma samples were collected during 4 months of the year after a 1-month interval, and Mn concentrations were assessed after wet digestion using an atomic absorption spectrophotometer.

Conflicts between Cattlemen and the Florida Panther: Insights and Policy Recommendations from Interviews with Florida Cattlemen

Journal Articles & Books
Décembre, 2015

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. Based on semi-structured interviews and group meetings with Florida cattlemen, we examine how cattlemen’s land stewardship practices support panther conservation, and causes of conflicts with the panther and wildlife agencies.

Effects of Vermicompost and Arbuscular Mycorrhizal Fungi on Soil Properties and Growth of Medicago polymorpha L

Journal Articles & Books
Décembre, 2015

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. Further, AM fungi treatment was applied in two levels (inoculating with and without AM fungi).

Paisang (Quercus griffithii): A Keystone Tree Species in Sustainable Agroecosystem Management and Livelihoods in Arunachal Pradesh, India

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. Paisang trees are conserved both by individuals and through community governance, because their leaves play a crucial role in sustaining 11 traditional cropping systems of the Monpa peoples.

Determinants of food security under changing land-use systems among pastoral and agro-pastoral households in eastern Ethiopia

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. Therefore, the objective of this paper was to assess the determinants of food security under changing land use and land management systems—from communal to private investment—using household survey data collected from pastoral and agro-pastoral communities. The data were analyzed using ordinary least-square econometric analysis.
