A Geographic Information System (GIS)-based model, using presence-only data, was used to predict suitability of habitat for large grazing ungulates on a Zimbabwean wildlife reserve. The management-driven study focused on rare and economically valuable herbivores during the resource-limited hot-dry season. The modelling software Biomapper was used to quantify species–habitat association and deri...
In the eastern U.S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these con...
Over time, community forests (CFs) have been established across the globe to meet various social, economic, and ecological needs. Benefits of CFs include conserving resilient natural resources ecosystem services, enhancing social economic capital, leveraging local indigenous knowledge in forest resource management decision-making. Research on U.S. is quite limited, cases that assessed show a wi...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
The decline in coastal environmental quality is a major global conservation problem (Bell et al. 1993; Short et al. 2001). Efforts to restore coastal environmental quality have been rapidly increasing. Restoration success is not simple to measure, especially when records on the original habitat condition are absent or scarce (Short et al. 2001). Ecological indicators and restoration goals need ...
Persian gazelle, Gazella subgutturosa, exists throughout arid and semiarid regions of Iran and has a key role in these frail ecosystems. Habitat degradation and population decline has placed it on the list of vulnerable species in 2008. The phylogenetic relationships of three Persian gazelle populations in the central part of Iran (i.e. Ghamishlou National Park and Wildlife Refuge, Mouteh Wildl...
Presence–absence data are used widely in analysis of wildlife–habitat relationships. Failure to detect a species’ presence in an occupied habitat patch is a common sampling problem when the population size is small, individuals are difficult to sample, or sampling effort is limited. In this paper, the influence of non-detection of occurrence on parameter estimates of logistic regression models ...
Purdue University Cooperative Extension Service • West Lafayette, Indiana The establishment and maintenance of food plots can be a component of any wildlife management plan. When used in conjunction with other habitat management techniques, food plots are useful for attracting wildlife. However, landowners may have unrealistic expectations about the utility and function of food plots. Food plot...
Beyond grazing, managed grasslands provide ecological services that may offer economic incentives for multifunctional use. Increasing biodiversity of plant communities may maximize net primary production by optimizing utilization of available light, water, and nutrient resources; enhance production stability in response to climatic stress; reduce invasion of exotic species; increase soil OM; re...
We read Borges et al. [1] and Goodin et al. [2] articles with interest in the context of considering the factors that effect speciality choice. Goodin et al. conclude that enriching a student’s calling in relation to speciality choice is vital to those who struggle with choosing a speciality. With certain specialities currently facing shortages, such as psychiatry, care of the elderly and emerg...
