fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major causes of fragmentation in forest landscapes. present investigation aims to trace landscape fragmentation in dense forests of golestan national park in northeast of iran betwe...

A total of 114 elk faecal samples from the Polesie National Park and adjacent forest districts were examined in 2013 and 2014. Three samples were positive. The positive samples were from the village of Wereszczyn, the Sobibor forest district, and the Polesie National Park and Forest district, Parczew. Morphometric examination revealed that the oocysts belong to the species Eimeria alces. This i...

evaluating the population density and spatial pattern of infected trees are one of the important criteria for selecting the management method and epidemiology of forest diseases. this study aimed at assessing the damage intensity and spatial-temporal mortality patterns of oak in qoroq forest park, golestan province. the health of oak trees was evaluated in seven transects by using quarter-point...

Extensive outbreaks of tree-killing insects are increasing across forests in Europe and North America due to climate change and other factors. Yet, little recent research examines visitor response to visual changes in conifer forest recreation settings resulting from forest insect infestations, how visitors weigh trade-offs between physical and social forest environment factors, or how visitor ...

The cooling effects of urban parks, which form “Park Cool Island” (PCI), can help decrease land surface temperature (LST) and mitigate urban heat island (UHI) effects. PCI intensity largely depends on the characteristics of urban parks. The relationship between PCI intensity and urban park characteristics such as urban park size has been well documented. However, it is still unclear how urban f...

The responses of urban park woodlands to large disturbances provide the opportunity to identify and examine linkages in social-ecological systems in urban landscapes.We propose that the Panarchy model consisting of hierarchically nested adaptive cycles provides a useful framework to evaluate those linkages. We use two case studies as examples – Cherokee Park in Louisville, Kentucky, USA and Tij...

Monitoring changes in landscape cover types has been a great concern for forest and wildlife managers. Both managers find it very important to know how much area is suitable for wildlife species and what areas are affected due to anthropogenic pressure. To address these concerns, evaluation of Chandoli National Park was done to see the changes that have taken place over the past 28 years. The N...

Kyasanur Forest disease (KFD), a tick-borne viral hemorrhagic fever, is endemic in five districts of Karnataka state, India. Recent reports of the spread of disease to neighboring districts of the Western Ghats, namely Chamarajanagar district in Karnataka, Nilgiri district in Tamil Nadu, Wayanad and Malappuram districts in Kerala, and Pali village in Goa are a cause for concern. Besides vaccina...
