“…From all collembolans found, only Sminthurides had been reported from aquatic environments, particularly neustonic (Folsom & Mills, 1938). Palacios-Vargas et al (2018) provide a more detailed analysis on the presence of collembolans in the Montebello Lakes.…”

“…The aim of the present study was to provide accurate data on the biodiversity of benthic communities of 18 tropical lakes in the Protected Natural Area and RAMSAR site "Lagunas de Montebello", Chiapas, southern Mexico. It should be noted that there are only 2 previous published studies (Guadarrama-Hernández et al, 2015;Palacios-Vargas et al, 2018) concerning benthic macroinvertebrates of this area.…”

Benthic macroinvertebrate community biodiversity of tropical lakes has been rarely addressed. The present study recognizes the taxonomic diversity of the deep benthic macroinvertebrate communities of 18 lakes of the Protected Natural Area "Lagunas de Montebello", Chiapas, Mexico. The lakes display different morphometric features and trophic states. Five sampling campaigns were carried out between 2013 and 2016. Forty-nine taxa (14 orders, 25 families, 40 identified genera, and 9 undetermined taxa) were recorded. Taxonomic richness varied between 0 and 19 taxa with a mean of 5 ± 6 taxa. The regional species richness was high compared to other tropical lakes in Mexico and worldwide; the richness per lake was similar to other tropical lakes. Chironomidae was the best-represented family with 17 genera. Even the studied lakes belong to the same lake district, low taxonomic similarity among them was found; 65.3% of genera were found in a single lake. Eutrophic shallow lakes had lower richness (2.5 ± 3.5, 0-5) compared to oligotrophic shallow lakes (5.0 ± 7.1, 0-10), and eutrophic deep lakes had lower richness (2.0 ± 1.8, 0-4) than oligotrophic deep lakes (7.0 ± 6.5, 0-19); nonetheless, we found no statistically significant differences. Eutrophication is reducing deep benthic community diversity, threatening these fragile ecosystems characterized by high taxonomic richness and singularity.

“…Groundwater connections (e.g., alluvial aquifers, epikarst systems) have been implicated as “interstitial highways” that can provide subsurface dispersal pathways for a wide range of subterranean arthropods (e.g., Lefébure et al., ; Ward & Palmer, ), but Collembola are not normally considered members of the interstitial groundwater community as they cannot complete life cycles while submerged (Deharveng, D'Haese, & Bedos, ). However, growing evidence suggests that they are not only present in these habitats, but can occur in abundance and comprise diverse communities (Bretschko & Christian, ; Deharveng et al., ; Palacios‐Vargas, Cortés‐Guzmán, & Alcocer, ; Shaw, Dunscombe, & Robertson, ).

At the confluence of vicariance and dispersal: Phylogeography of cavernicolous springtails (Collembola: Arrhopalitidae, Tomoceridae) codistributed across a geologically complex karst landscape in Illinois and Missouri

The processes of vicariance and dispersal are central to our understanding of diversification, yet determining the factors that influence these processes remains a significant challenge in evolutionary biology. Caves offer ideal systems for examining the mechanisms underlying isolation, divergence, and speciation. Intrinsic ecological differences among cavernicolous organisms, such as the degree of cave dependence, are thought to be major factors influencing patterns of genetic isolation in caves. Using a comparative phylogeographic approach, we employed mitochondrial and nuclear markers to assess the evolutionary history of two ecologically distinct groups of terrestrial cave‐dwelling springtails (Collembola) in the genera Pygmarrhopalites (Arrhopalitidae) and Pogonognathellus (Tomoceridae) that are codistributed in caves throughout the Salem Plateau—a once continuous karst region, now bisected by the Mississippi River Valley in Illinois and Missouri. Contrasting phylogeographic patterns recovered for troglobiotic Pygmarrhopalites sp. and eutroglophilic Pogonognathellus sp. suggests that obligate associations with cave habitats can restrict dispersal across major geographic barriers such as rivers and valleys, but may also facilitate subterranean dispersal between neighboring cave systems. Pygmarrhopalites sp. populations spanning the Mississippi River Valley were estimated to have diverged 2.9–4.8 Ma, which we attribute to vicariance resulting from climatic and geological processes involved in Mississippi River Valley formation beginning during the late Pliocene/early Pleistocene. Lastly, we conclude that the detection of many deeply divergent, morphologically cryptic, and microendemic lineages highlights our poor understanding of microarthropod diversity in caves and exposes potential conservation concerns.

Descriptions of chromosomal rearrangements, geographic distributions and frequencies of nine siblings and 28 cytotypes of the Simulium arcticum Malloch complex are presented. Findings are based on six data sets that include approximately 21,000 chromosomally analyzed larvae from throughout the known geographic range of S. arcticum. This is the largest chromosomal data set for any North American complex of black flies. This summary emphasizes the need to chromosomally analyze taxa of black flies since this type of analysis can result in, not only, a better understanding of the number of taxa in a complex and their relationships but also, it may help to understand the initial stages of reproductive isolation within otherwise morphologically identical groups. Geographically, the streams of eastern Alaska, the entire province of the Yukon and northern Mexico should be sampled. Taxonomically the many cytotypes should be tested for reproductive status when they occur in sympatry with other siblings and cytotypes of the complex. Finally, comparative multi-omic research would be useful.
