Environmental and spatial influences upon species composition of a termite assemblage across neotropical forest islands

et al. 2003

Patterns of species composition in a neotropical termite assemblage were studied in relation to early effects of forest fragmentation as well as other sources of environmental and spatial heterogeneity. Termite diversity surveys were carried out at three mainland forest sites, and 10 islands of varying size, in an area of lowland tropical forest that had been flooded 4 y earlier, during the creation of the Petit Saut hydroelectric project in French Guiana. The ‘ghost forest’ of dead emergent trees in the flooded zone was also studied for its influence on island termite assemblages. Results suggested that the effects of forest fragmentation upon the total assemblage, and upon soil-feeders in particular, were subordinate to the influence of forest understorey palm density, and the closely associated gradients of soil humus depth and soil pH. Moreover, gradients for these three variables were uncorrelated with forest fragmentation and probably reflected spatial environmental heterogeneity pre-dating inundation events. Nevertheless, factors associated with forest fragmentation appeared to have had a significant effect on changes in termite species composition across the study site, primarily in structuring the wood- and leaf-litter-feeder assemblage. Effects upon the latter were not apparently a result of influx of species from the ghost forest. Purely spatial variation also influenced β-diversity changes in species composition across the site. In conclusion, the effects of forest fragmentation upon termites appear to have been relatively mild compared with other faunal groups, 4 y after flooding. Nevertheless, we predict that the effects of fragmentation on termite assemblages will ultimately be negative. This study also points to the importance of Amazonian understorey palms in structuring a tropical forest termite assemblage.

The impact of social complexity on the efficacy of natural selection in termites

In eusocial species, reproduction is monopolized by a few reproductive individuals. From the perspective of population genetics, this implies that the effective population size (Ne) of these organisms is likely to be smaller compared to solitary species, as has been proposed in the literature for eusocial Hymenoptera. In this study, we investigate the genomic consequences of eusociality in termites (Isoptera) across two different timescales. First, by analyzing transcriptome data from 66 Blattodea species, we focus on the ratio of nonsynonymous to synonymous mutations (dN/dS) as a marker of natural selection efficiency and effective population size. Our results demonstrate an elevated dN/dS ratio in termites compared to other Blattodea members, which further generalizes the idea that convergent evolution toward eusociality strongly reduces effective population size and genome-wide efficiency of natural selection. Then, by comparing 68 termite transcriptomes, we show that this decrease in natural selection efficiency is even more pronounced in termites displaying high levels of social complexity. This study contributes to understanding the complex interplay between social structures and natural selection patterns, highlighting the genetic footprint of eusociality in shaping termite evolution.

Compendium of neotropical termite genera: morphology and ecology database, ontology and applicability

Biological databases are fundamental tools for modern research, offering a wide range of relevant data. Over the past two decades, the explosion of interconnected data has spurred the development and adoption of database technologies. Here we propose the ﬁrst termite morphology and ecology database model, coupled with a standard ontology, and apply the database in a speciﬁc study. With the database, it was possible to extract information about the internal and external morphology and ecology of the 108 genera that occur in the Neotropical region. We also created an ontology model based on the internal and external morphology of termites to support the integration between databases. Furthermore, we show that it is possible to apply the database to extract information that can be used in a speciﬁc study. Keywords: Isoptera. Catalogue. Graph. Entomology.
