Digests on the science of corridors

Unpaved roads as seed corridors

May 13th, 2013|

Roads are often seen as barriers to movement and dispersal.  However, not all roads are created equal, and new research suggests that some types of human developed roads can in fact be beneficial to species [...]

The dangers of narrow corridors

April 19th, 2013|

Corridors are envisioned to benefit biodiversity -- re-connecting landscapes that have become fragmented, and providing safe passage for plants and animals across landscapes that are increasingly dominated by humans.  Yet, corridors could cause harm to [...]

New methods to calculate wildlife corridors

January 11th, 2013|

A common method for identifying potential corridor paths is to use least-cost modeling, which uses a resistance surface to calculate different paths with the lowest cumulative resistance between source and destination locations. However, this type [...]

Issues in Ecology series: connectivity

October 22nd, 2012|

The Ecological Society of America released the sixteenth installment of their Issues in Ecology series, which focuses on using landscape connectivity in conservation planning. In these papers, experts summarize an area of ecological research for [...]

Assessing connectivity using stress hormones

October 14th, 2012|

Assessing the resistance a landscape imposes on movement between habitat fragments is critical for estimating landscape connectivity. While several methods have been used to estimate landscape resistance, many of these methods are time consuming and [...]

Connectivity across the United States

August 29th, 2012|

A key issue in connectivity is determining which areas are priorities for management actions. Since not all fragmented habitat can or should be of high concern for conservation, it is critical for scientists and managers [...]

Measuring functional connectivity with long-term data

August 29th, 2012|

Functional connectivity refers to the landscape's role in allowing organisms to move between habitat fragments. Traditionally, researchers estimated movement between patches directly using capture-recapture models, or indirectly by estimating genetic divergence between populations. In a [...]

Connectivity for a diversity of species

August 29th, 2012|

Figure 3C from Cushman & Landguth 2012 An ideal in conservation planning is to create connected habitat that will simultaneously benefit as many species as possible. However, little is known about whether it is [...]
