01. August 2018
Publication date: August 2018 Source:Ecological Indicators, Volume 91 Author(s): Ashleigh Marshall, Henrike Schulte to Bühne, Lucie Bland, Nathalie Pettorelli Ecosystem collapse, i.e. the endpoint of ecosystem decline, is a central concept of IUCN Red List of Ecosystems (RLE) assessments and the identification of ecosystems most vulnerable to global environmental change. Estimating collapse risk can be challenging for ecosystems reliant on a few dominant species to perform most of their functions because the range of suitable and feasible indicators is small. This study...
At which spatial and temporal scales can fungi indicate habitat connectivity?
01. August 2018
Publication date: August 2018 Source:Ecological Indicators, Volume 91 Author(s): Jenni Nordén, Jens Åström, Torbjörn Josefsson, Stefan Blumentrath, Otso Ovaskainen, Anne Sverdrup-Thygeson, Björn Nordén Isolation of habitats in space and time affects species globally and in a multitude of ecosystems. It is however often difficult to assess the level of isolation from the point of view of the focal species. Indicator species are often used to assess ‘conservation value’ of habitats. One such approach involves the use of wood-decaying fungal species as indicators...
