At which spatial and temporal scales can fungi indicate habitat connectivity?
2018
Isolation of habitats in space and time affects species globally and in a multitude of ecosystems [1]. It is however often difficult to assess the level of isolation from the point of view of the focal species [2]. Wood-decaying fungal species have been used as indicators of 'conservation value' in Europe [3] and North America. The indicator species were commonly assigned based on expert opinions, but few scientific evaluations have been performed of what these species actually indicate. Building on previous classifications of wood-decaying fungal indicator species on Norway spruce, we hypothesized that indicator species would differ from non-indicator species in how they respond to local t…
Linking conservation biology to community assembly processes with hierarchical modelling of species communities
2018
Applications in conservation biology require a profound understanding of community ecology, in particular of the processes that determine the assembly and dynamics of species assemblages at different spatiotemporal scales. To facilitate the integration between conceptual and statistical approaches in community ecology and conservation biology, we have developed Hierarchical Modelling of Species Communities (HMSC) as a general, flexible framework for modern analysis of community data (1,2,3). HMSC belongs to the class of joint species distribution models, and it makes it possible to derive simultaneously species- and community level inference from data on species occurrences, environmental c…
Predicting the future for endangered birds
2018
Predicting the future for endangered birds Climate and habitat explain to a large extent the distribution and abundance of species but nowadays climate change and increasing pressure on land use are causing notable declines in various species populations, and even extinctions [1]. From the cost-efficient conservation management point-of-view it is important to know which (currently common) species are in risk to become endangered in the future. To prevent species from becoming endangered we should also understand which factors are causing population declines. Here we use presence-absence data on 265 bird species to model their future breeding distribution areas. We use species which were ob…
