Article
Full-text available
Context Connectivity between habitat patches is a recognized conservation action to conserve biodiversity in a rapidly changing world. Resistance surfaces, a spatial representation of cost of movement across the landscape, are often the foundation for connectivity analyses but working with them can be daunting due to the diversity and complexity of...

As ecological data and associated analyses become more widely available, synthesizing results for effective communication with stakeholders is essential. In the case of wildlife corridors, managers in human-dominated landscapes need to identify both the locations of corridors and multiple stakeholders for effective oversight. We synthesized 5 indep...

Abstract Rapid impact assessment of cyclones on coastal ecosystems is critical for timely rescue and rehabilitation operations in highly human‐dominated landscapes. Such assessments should also include damage assessments of vegetation for restoration planning in impacted natural landscapes. Our objective is to develop a remote sensing‐based approac...
Article
Maintaining or restoring connectivity among wildlife populations is a primary strategy to overcome the negative impacts of habitat fragmentation. Yet, current connectivity planning efforts typically assess landscape resistance, the ability of organisms to cross various biophysical elements in a landscape, while overlooking the various ways in which...

Article impact statement: Combining native and non‐native species to evaluate biodiversity is overly simplistic and may undermine the conservation of ecosystems.
Article
Zoonosis-based epidemics are inevitable unless we revisit our relationship with the natural world, protect habitats and regulate wildlife trade, including live animals and non-sustenance products. To prevent future zoonoses, governments must establish effective legislation addressing wildlife trade, protection of habitats and reduction of the wildl...

Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including t...

Article
Linear infrastructure development is an important driver of forest fragmentation leading to habitat and biodiversity loss as well as disruption of critical ecosystem processes. The tropical forests of India are increasingly impacted by infrastructure development. Little quantitative information is available on the extent of fragmentation due to lin...
Article
Full-text available
Background Maintaining and restoring connectivity between source populations is essential for the long term viability of wide-ranging species, many of which occur in landscapes that are under pressure to meet increasing infrastructure needs. Identifying barriers in corridors can help inform conservation and infrastructure development agencies so th...
Article
Full-text available
Large connected landscapes are paramount to maintain top predator populations. Across their range, tiger (Panthera tigris) populations occur in small fragmented patches of habitat, often isolated by large distances in human-dominated landscapes. We assessed connectivity between 16 protected areas (PAs) in central India, a global priority landscape...

Sloth bears (Melursus ursinus) are endemic to the Indian subcontinent. As a result of continued habitat loss and degradation over the past century, sloth bear populations have been in steady decline and now exist only in isolated or fragmented habitat across the entire range. We investigated the genetic connectivity of the sloth bear meta-populatio...
Article
Full-text available
The sloth bear (Melursus ursinus) is a threatened species endemic to the Indian subcontinent. To date, no reliable method has been developed for identifying individuals or monitoring their populations. Here we describe a non-invasive genetic monitoring technique for individual identification of sloth bears. After testing 18 microsatellites develope...

The jungle cat (Felis chaus), a small-sized felid, is distributed across Southeast and South Asia to Egypt in Africa. In India, it is one of the most common small cat species but no reliable methods are available to monitor its population status. We describe a non-invasive genetic monitoring technique using fecal samples for individual identificati...
Article

Gene flow is a critical ecological process that must be maintained in order to counteract the detrimental effects of genetic drift in subdivided populations, with conservation benefits ranging from promoting the persistence of small populations to spreading adaptive traits in changing environments. We evaluated historical and contemporary gene flow...
Article
Full-text available
Understanding the patterns of gene flow of an endangered species metapopulation occupying a fragmented habitat is crucial for landscape-level conservation planning and devising effective conservation strategies. Tigers (Panthera tigris) are globally endangered and their populations are highly fragmented and exist in a few isolated metapopulations a...
Article
Full-text available
We investigated the spatial genetic structure of the tiger meta-population in the Satpura-Maikal landscape of central India using population- and individual-based genetic clustering methods on multilocus genotypic data from 273 individuals. The Satpura-Maikal landscape is classified as a global-priority Tiger Conservation Landscape (TCL) due to its...
Article
Full-text available
We describe a highly polymorphic microsatellite panel for identifying individual leopards using DNA from scat. After successfully screening 16 published microsatellites, we optimized a panel of 7 microsatellites that yields a Probability of Identity between siblings value of 5.24E-04. We used this panel to identify 217 individuals from 287 leopard...
Article
Full-text available
Aim Habitat loss and fragmentation can influence the genetic structure of biological populations. Large terrestrial predators can often avoid genetic subdivision due to fragmentation because they have high rates of dispersal-mediated gene flow. Leopards (Panthera pardus) are found in a variety of habitats and are the most widely distributed of the...

Question
Hi all,
I have a large set of polygons. I want to
(1) calculate pairwise distances between polygons (so one polygon should be connected to several others). I can do this using the generate table in ArcMap.
and
(2) set of lines connecting these polygons, and this pairwise distance file can link to.
The only way I can think of doing this is through linkage mapper, but I dont want all the least-cost etc analysis.
Is there a simpler way to do this?
Thanks
