“…Chironomids were separated from the remainder and identified up to the genus-or species level with established keys (Smith & Distler, 1981;Wiederholm, 1983;Pillot, 1984aPillot, , b, 2009Vallenduuk & Pillot, 2007). The taxonomy used here is that of Spies & Saether (2004), with adjustments following H. M. Pillot (personal communication).…”

Chironomid faunal composition represented by taxonomic distinctness index reveals environmental change in a lotic system over three decades

The widely distributed family of the Chironomidae represents the most diverse and abundant group of macroinvertebrate fauna and potentially provides information on stream water quality and the effect of anthropogenic disturbances. Change in the chironomid faunal composition in the Southern Morava River basin (Serbia) was examined by comparing data from 1981 and 2010. We tested the performance of the parameter ''taxonomic distinctness'' (delta ? ) as an indicator of water quality and examined the possible relationship between delta ? and water quality using PCA. The 2010 survey yielded 96 taxa in 28 localities over three seasons. In total, 10,179 specimens represented the five subfamilies. Chironomid diversity was captured with the index delta ? that is based upon taxonomic distinctiveness and purported to be independent of sampling effort. Delta ? was correlated to total species richness and is significantly higher now than it was in 1981. In keeping with PCA results, delta ? was increasing in accordance with water quality increase. We conclude that delta ? is a useful measure for estimating anthropogenic disturbance over time. The linear relationship between delta ? and the water quality gradient gives rise to a novel metric, independent of sampling effort, in the multimetric approaches of analyzing macroinvertebrate assemblage data for bioassessments.

“…Having this in mind, one could expect that the abundance-distribution relationship would also occur at higher taxonomic levels other than species, which would be desirable bearing in mind the limited knowledge available for Neotropical fauna. This seems especially suitable for chironomids, in which there are a high number of synonyms and unclear descriptions (Spies & Saether, 2004) that create problems associated with differing species validity (Ferrington, 2008).…”

The role of niche measures in explaining the abundance–distribution relationship in tropical lotic chironomids

et al. 2009

The positive relationship between species regional distribution and local abundance is one of the most ubiquitous patterns in ecology. Among the hypotheses proposed to explain the relationship, the niche breadth and the niche position (or habitat availability) hypothesis are the most investigated. An unappreciated issue, but that is likely to be important for the understanding the relationship is the nature of variables used to estimate niche measures. Here, we analyzed the form of this relationship in lotic chironomid genera and tested whether niche measures estimated from local and landscape variables explain the observed pattern. Analyses were based in 47 forested streams within Southeastern Brazil. From our data set, we randomly partitioned the data in two non-overlapping sets to estimate taxa distribution and abundance (Distribution Data; n = 23 sites) and to generate niche measures (Niche Data; n = 24). We repeated that process 1,000 times, and for each one, we generated niche breadth and position measures using in-stream and landscape variables and estimated abundance and distribution for each taxa. With these, we estimated the relationship between both abundance and distribution and niche measures using ordinary least-squares regressions. We found no relationship between niche position estimated from local variables and local abundance nor regional distribution. There was a negative relationship between niche position estimated from landscape and local abundance, and regional distribution. We found a positive relationship between niche breadth (local and landscape) and both local abundance and regional distribution. When the relationship was significant, both niche position and niche breadth explained less than a half of total variation in abundance and distribution. This suggests that not only niche-based processes, but also other mechanisms may be responsible for the abundance-distribution relationship in lotic chironomids. A novel finding of this study was that although there was much unexplained variability around the relationships, niche breadth was a better predictor of abundance and distribution than niche position. We suggest that future studies should investigate if spatial

“…As mentioned above, Kieffer's personal collection is presumably lost (Gagné 1994;Spies and Saether 2004) so we cannot confirm the identification of our specimens based on direct comparisons with the type material. Nevertheless, a detailed examination of our collected specimens and their galls revealed that B. mendocinus Kieffer and Jö rgensen actually represents an odd form of Allorhogas, with an extremely rugose cuticule in most of the head and mesosoma (see below).…”

One of the first reported gall-associated braconids, from 1910, Bracon mendocinus Kieffer and Jö rgensen, is removed from the subfamily Braconinae and transferred to the doryctine genus Allorhogas, A. mendocinus (Kieffer and Jö rgensen) comb. nov. A new species morphologically similar to A. mendocinus, A. joergenseni Martinez and Zaldivar-Riveró n sp. nov., is also described. Additionally a neotype is designated for B. mendocinus Kieffer and Jö rgensen. We base our conclusions on the morphological examination of recently collected specimens from central Argentina associated with galls on Lycium chilense (Solanaceae), as well as on the DNA variation at 28S ribosomal RNA and cytochrome oxidase subunit I (COI) mitochondrial DNA genes.
