Data from: Isolated trees support lower bird taxonomic richness than trees within habitat patches but similar functional diversity
<p><span>Large isolated trees are keystone structures that can help maintain biodiversity in fragmented landscapes, with evidence that open areas with isolated trees may support similar levels of taxonomic diversity to nearby patches of habitat. However, it is not clear if isolated trees can support the same diversity of ecological functions as trees in habitat patches. We compared species richness, community composition and functional diversity of birds in trees at forest edges and isolated trees. Twenty isolated trees and ten edge trees of American muskwood (<i>Guarea guidonia</i>) were selected, and sampled on 11 occasions, each of 20 minutes, over four months. All individual birds that landed at trees were recorded using a standardized protocol. Species richness was, on average, almost twice as high at edge trees than at isolated trees. Taxonomic composition differed between edge and isolated trees, with many forest-dependent birds restricted to edge trees, and some open-area birds restricted to isolated trees. Overall functional diversity was similar at edge and isolated trees, but some ecological functions (e.g. frugivory) were less frequent, while others (e.g. granivory) were more frequent at isolated compared to edge trees. Isolated trees are important for supporting many ecological functions in modified areas. However, the maintenance of forest patches is essential to complement the provision of such functions in modified landscapes. </span></p>
Data from: Impacts of habitat on butterfly dispersal in tropical forests, parks and grassland patches embedded in an urban landscape
<p>Dispersal distances of 17 species of butterflies in tropical Singapore were significantly greater in forest than in urban habitat. Butterflies in urban plots frequently moved within suitable habitat (park/grassland) patches but rarely crossed non-habitat patches suggesting potential isolation and a need for urban corridors.</p>
Data from: Habitat patch use by fishers in the deciduous forest-dominated landscape of the central Appalachian Mountains, USA
Fishers (Pekania pennanti) are often associated with the coniferous and mixed forests of the northern United States and central Canada, and their ecology has been studied extensively in portions of their distributional range. Recently, natural range expansion and reintroductions have led to recolonization by fishers of portions of the central Appalachian Mountains, USA, where deciduous forest is the dominant vegetation type. We used noninvasive hair snare surveys and microsatellite genetic analysis to detect fishers in the central Appalachian Mountains of Pennsylvania, USA. We used these detections within an occupancy modeling framework to explore habitat patch use by fishers and the forest characteristics and land use features that influenced it. We found that the likelihood of patch use by fishers was related to forests with higher proportions of low-density residential areas. Our results also suggested lower road densities might be related to higher likelihood of fisher patch use. Fishers in Pennsylvania tolerated some forms of land development. Patch use was not driven by forest type or canopy cover, at least within our deciduous forest-dominated study areas. Future research identifying the threshold values at which forest cover and land development affect patch use by fishers in the central Appalachian Mountains will better inform management decisions with respect to sites for future reintroduction of fishers.

Data from: Habitat amount, not patch size and isolation, drives species richness of macro‐moth communities in countryside landscapes
Aim: Our aim is to test whether species richness patterns are best explained by the effect of the total amount of habitat within the landscape, or instead by a combination of patch size and patch isolation effects. To this end, we jointly contrast the habitat amount hypothesis and countryside biogeography with patch size and isolation concepts from island biogeography. Location: Three multi-habitat landscapes in Peneda-Gerês National Park, NW Portugal. Taxon: Macro-moths (Lepidoptera). Methods: Light-trapping using a semi-nested design at 84 fixed sites which were each repeatedly sampled six times. Results: Autocovariate models show that sampling sites with a higher number of forest and meadow macro-moth species (alpha diversity) were surrounded by a higher amount of forest and meadow habitat, respectively within a 160 and 320 m radius (scale of effect). These top-ranked models, containing only habitat amount as a significant variable, had lower AIC than models (only) containing patch size and/or isolation. Complementary to this, the countryside species-area relationship (SAR) model outperforms the classic SAR model, so that the effective area of habitat explains landscape species richness (gamma diversity) across spatial scales (beta diversity) better than the classic SAR. Specifically, we show that forest macro-moths have a higher spatial turnover than meadow macro-moths and that, on average, there are more species in forest than in meadow habitat. Main conclusions: The habitat amount hypothesis predicts alpha species richness in multi-habitat landscapes better than do patch size and isolation while the countryside SAR predicts beta and gamma diversity better than the classic SAR. We suggest that evidence is mounting to revise the application of the classical approaches of island biogeography and metapopulation theory to conservation biogeography.
Fig. 8 in A comparative exploration of the inquiline and prey species of Nepenthes rafflesiana pitchers in contiguous and fragmented habitat patches in Singapore
Fig. 8. First and second (a) and second and third (b) dimensions of the three-dimensional NMDS of pitcher prey assemblages. Points represent prey assemblages of individual pitchers, being coloured according to pitcher type (with green points representing lower pitchers and beige ones representing upper ones) and are filled for pitchers found within the Central Catchment Nature Reserve (CCNR) and unfilled for those outside of it. Texts denote prey taxon centroids and are sized proportionally with the frequency of occurrence of the taxa they denote. Points found close to species centroids are more likely to contain the corresponding prey taxon. Stress = 0.174.
