Data from: Cryptic diversity, high host specificity and reproductive synchronization in army ant-associated Vatesus beetles
Army ants and their arthropod symbionts represent one of the most species-rich animal associations on Earth, and constitute a fascinating example of diverse host-symbiont interaction networks. However, despite decades of research, our knowledge of army ant symbionts remains fragmentary due to taxonomic ambiguity and the inability to study army ants in the lab. Here we present an integrative approach that allows us to reliably determine species boundaries, assess biodiversity, match different developmental stages and sexes, and to study the life cycles of army ant symbionts. This approach is based on a combination of community sampling, DNA barcoding, morphology and physiology. As a test case, we applied this approach to the staphylinid beetle genus Vatesus and its different Eciton army ant host species at La Selva Biological Station, Costa Rica. DNA barcoding led to the discovery of cryptic biodiversity and, in combination with extensive community sampling, revealed strict host partitioning with no overlap in host range. Using DNA barcoding, we were also able to match the larval stages of all focal Vatesus species. In combination with studies of female reproductive physiology, this allowed us to reconstruct almost the complete life cycles of the different beetle species. We show that Vatesus beetles are highly adapted to the symbiosis with army ants, in that their reproduction and larval development are synchronized with the stereotypical reproductive and behavioral cycles of their host colonies. Our approach can now be used to study army ant-symbiont communities more broadly, and to obtain novel insights into co-evolutionary and ecological dynamics in species-rich host-symbiont systems.
Alpha-diversity, Beta-diversity and host-specificity of wood-boring longhorn beetle (Cerambycidea) in Asian tropical and subtropical forests
<p><span>A long-debated question in ecology is whether the hyper-diversity of tropical plant-feeding insects is a direct consequence of high tropical plant diversity and/or should be attributed to increases in host plant specialization. To address this debate, we used the longhorn beetle as a study system because their larval stages feed on the xylems of trees and lianas. We hypothesized that longhorn beetles show higher host-specificity in tropical forests than in other forests; alternatively, the high longhorn beetle diversity in the tropics may simply be owing to more diverse host plants. We therefore designed an investigation in tropical and subtropical forests to test these hypotheses. We adapted several analyses (i.e., non-metric multidimensional scaling analysis, alpha-diversity, beta-dissimilarity indices comparisons, and variation partitioning based on redundancy analysis) to compare the species diversity of plants and longhorn beetles in different forests. Our results show that both the plant and beetle species in the tropical and subtropical areas were well-stratified (non-metric multidimensional scaling analysis). The beetle alpha-diversity in the tropical forests was significantly higher than that in the subtropical forests, but the plant alpha-diversity in the two types of forests were not significantly different. The beta-dissimilarity comparison showed that the plant species exerted a significant influence on beetle compositional assemblage in the tropical forests, but not in the subtropical forests. Finally, the variation partitioning results showed that both plant species and plant phylogenetic beta-diversity possessed significant explanatory power for beetle assemblage composition in the tropical forests, but not in the subtropical forests. We conclude that wood-boring longhorn beetles show higher host-specificity in tropical forests than in subtropical forests, and the high diversity of wood-boring longhorn beetles in tropical forests might be explained to a large extent by their more finely partitioned diet-breadth.</span></p>
