Diversity patterns and community structure of the macrofauna along the beach-inland transition zone of small tropical islands: supporting raw data and code
<p>Biodiversity follows distinct and observable patterns. Where to systems meet, biodiversity is often increased, due to overlapping occurrence ranges and the presence of specialized species that can tolerate the dynamic conditions of the transition zones. One of the most pronounced transition zones occurs at shores, where oceans and terrestrial habitat collide, forming the shore-inland transition zone. The relevance of this transition zone in shaping a system's community structure is particularly pronounced on small islands due to their high shore-to-inland-area ratio. However, the community structure of insular faunas along this transition zone is unknown. Here, we investigated the diversity patterns along the beach-inland transition zone of small islands and tested the hypothesis that species diversity increases towards the transition zone where beach and interior habitat meet. By measuring environmental parameters, resource availability, and macrofauna diversity along transects running across the beach-inland transition zone, we show that a gradual change in species composition from beach to the inland exists, but neither taxa richness, Shannon diversity, nor overall abundance change significantly. These findings give important insight into insular community structure at the transition zone from sea to land that are relevant to better understand the dynamic and unique characteristics of insular ecosystems.</p>

Data from: Interactions between C:N:P stoichiometry and soil macrofauna control dung decomposition of savanna herbivores
1. Although dung of mammalian herbivores is an important pathway for nutrient return in savanna ecosystems, differences in dung decomposition rates among species have been little studied. 2. We measured rates of dung deposition and decomposition for various herbivores in a moist Tanzanian savanna, and related differences among species to nutrient concentrations and the activities of soil macrofauna (e.g., different mesh sizes of decomposition bags, or presence and absence of dung beetles). 3. Dung C:N:P stoichiometry varied widely among species, which could in part be explained by differences in feeding strategy (browsers vs. grazers) and digestive physiology (ruminants vs. non-ruminants). Rates of both decomposition and nutrient release were influenced by the C:N:P stoichiometry of dung, with lower relative losses of the least abundant nutrient. Surprisingly, soil macrofauna increased relative losses of the least abundant nutrient, thereby stabilizing the ratio of N loss to P loss. Dung beetles increased rates of N and P release from wildebeest dung significantly and also increased N availability in the soil. 4. We conclude that rates of nutrient return in dung depend not only on where herbivores deposit their dung, but also on its C:N:P stoichiometry, the activity of soil macrofauna, and interactions between these factors. These factors may therefore influence the relative availabilities of N and P in the soil and hence the functioning of savanna ecosystems.

The pink dots represent each dependent (marine debris on ghost crab burrow) and independent variables (distance from urban settlements). Blue shaded area indicates 95% confidence intervals and pink line is the distribution of residuals. Blue line is the regression straight. Only significant (p < 0.05) predictors were considered in the effects plot.
