V2 - Space use of invertebrates in terrestrial habitats: phylogenetic, functional and environmental drivers of interspecific variations
<p>VERSION 2</p>
Data from: Differences in sibling cooperation in presence and absence of parental care in a genus with interspecific variation in offspring dependence
<p>The widely spread evolutionary strategy of parental care is considered an important driver of social evolution. While offspring were long thought to primarily interact competitively, recent studies revealed the potential importance of sibling cooperation. Theories suggest that the degree of cooperation in offspring interactions depends on the degree of offspring dependence on parental care: offspring unable to forage on their own should compete more, whereas more independent juveniles may increase the degree of cooperation. In this study, we tested the occurrence of sibling cooperation in the absence of post-hatching care in several burying beetle species exhibiting varying degrees of offspring dependence. To this end, we measured larval growth rate and survival in the presence and absence of pre-hatching care using different brood sizes. We found that sibling cooperation cannot be exclusively explained by offspring dependence on parental care. While only species with more independent larvae cooperated when receiving pre-hatching care, larval cooperation occurred across species in the absence of care. The latter result suggests that sibling cooperation was already present in an early ancestor of the genus <em>Nicrophorus</em>. Overall, these findings give important insights into the transition from facultative to obligate family life.</p>

Dispersal ability and niche breadth influence interspecific variation in spider abundance and occupancy
<p><span>The relationship between species local abundance and their regional distribution (occupancy) is one of the most extensively recognised and investigated patterns in ecology. While exceptions exist, the generally held model is that locally abundant species also tend to be more widespread geographically. However, there is only a limited understanding of both the mechanisms driving this relationship, and their scale dependency. Here we use occupancy and abundance data for 123 species of spider from across the Canary Islands to understand how both dispersal ability and niche breadth might mediate variation among species for local abundance and occupancy. We test the predictions that (i) dispersal ability explains variation among species for both abundance and occupancy, and (ii) species with a higher degree of habitat specialisation, reflecting more limited niche breadth, will have both higher occupancy and abundance. We find no evidence within habitat patches for an effect of dispersal ability on either local abundance or site occupancy, while across all patches species with higher dispersal ability tend to occupy more sites. Species largely restricted to laurel forests have higher abundance than species with broader niche breadth, but similar occupancy. </span><span>The study revealed that dispersal ability and niche breadth were significant predictors of the abundance-occupancy relationship, highlighting the importance of both factors for understating patterns of abundance and occupancy among spider species.</span></p>
