“…Trichoptera, Hemiptera, and freshwater molluscs were among the most diverse groups. This observation is in line with rivers of the Mekong Basin, known to host one of the highest diversity of these groups (Bogan, 2008;De Moor & Ivanov, 2008;Polhemus & Polhemus, 2008;Strong et al, 2008). On the other hand, the low representation of Plecoptera and Crustacean was predictable.…”

-In order to assess the impact of water release in the downstream area of the Nam Theun 2 Reservoir (Lao PDR), the spatial and temporal variation of benthic macroinvertebrates was explored. Between 2010 and 2012, five sites were monitored in the Nam Gnom Basin, a tributary of the Xe Bangfai River, receiving the turbinated waters. Repeatedtime collections revealed the presence of 109 taxa mainly identified to the family level, attesting to a rich biota. Preliminary results did not show shifts in diversity, population composition, and feeding metrics. Redundancy Analysis indicated that the altitudinal gradient (i.e. altitude and altitude-related variables) remained the major environmental factor influencing the macroinvertebrates distribution before water discharge. The presence of a tributary downstream of the release point, and the respect of the natural river inflow can explain the preservation of natural conditions. More samples and a strengthened ecological knowledge of Southeast Asian macroinvertebrates are still required to confirm these preliminary results.Key words -freshwater invertebrates, Southeast Asia, biomonitoring, hydropower, downstream section Résumé -Afin d'évaluer l'impact du relâcher des eaux dans la zone aval du Réservoir Nam Theun 2 (RDP du Laos), la variabilité spatio-temporelle des invertébrés aquatiques a été étudiée.

“…Two climatic biotic provinces are recognized within Gondwana: the northern Tropical Gondwana, which includes northern South America, Africa, Madagascar, India, New Guinea, and northern Australia; and the southern Temperate Gondwana, which includes southern South America, South Africa, Australia, Antarctica, New Caledonia, and New Zealand (Sanmartín and Ronquist 2004). In the Neotropical Trichoptera, some of these affinities are discussed by de Moor and Ivanov (2008) and Holzenthal and Blahnik (2010).…”

Whole genome sequencing for generating SNP data is increasingly used in population genetic studies. However, obtaining genomes for massive numbers of samples is still not within the budgets of many researchers. It is thus imperative to select an appropriate reference genome and sequencing depth to ensure the accuracy of the results for a specific research question, while balancing cost and feasibility. To evaluate the effect of the choice of the reference genome and sequencing depth on downstream analyses, we used five confamilial reference genomes of variable relatedness and three levels of sequencing depth (3.5×, 7.5× and 12×) in a population genomic study on two caddisfly species: Himalopsyche digitata and H. tibetana . Using these 30 datasets (five reference genomes × three depths × two target species), we estimated population genetic indices (inbreeding coefficient, nucleotide diversity, pairwise F ST , and genome‐wide distribution of F ST ) based on variants and population structure (PCA and admixture) based on genotype likelihood estimates. The results showed that both distantly related reference genomes and lower sequencing depth lead to degradation of resolution. In addition, choosing a more closely related reference genome may significantly remedy the defects caused by low depth. Therefore, we conclude that population genetic studies would benefit from closely related reference genomes, especially as the costs of obtaining a high‐quality reference genome continue to decrease. However, to determine a cost‐efficient strategy for a specific population genomic study, a trade‐off between reference genome relatedness and sequencing depth can be considered.
