  • Aquatic Insects Are Dramatically Underrepresented in Genomic Research
    insects Communication Aquatic Insects Are Dramatically Underrepresented in Genomic Research Scott Hotaling 1,* , Joanna L. Kelley 1 and Paul B. Frandsen 2,3,* 1 School of Biological Sciences, Washington State University, Pullman, WA 99164, USA; [email protected] 2 Department of Plant and Wildlife Sciences, Brigham Young University, Provo, UT 84062, USA 3 Data Science Lab, Smithsonian Institution, Washington, DC 20002, USA * Correspondence: [email protected] (S.H.); [email protected] (P.B.F.); Tel.: +1-(828)-507-9950 (S.H.); +1-(801)-422-2283 (P.B.F.) Received: 20 August 2020; Accepted: 3 September 2020; Published: 5 September 2020 Simple Summary: The genome is the basic evolutionary unit underpinning life on Earth. Knowing its sequence, including the many thousands of genes coding for proteins in an organism, empowers scientific discovery for both the focal organism and related species. Aquatic insects represent 10% of all insect diversity, can be found on every continent except Antarctica, and are key components of freshwater ecosystems. However, aquatic insect genome biology lags dramatically behind that of terrestrial insects. If genomic effort was spread evenly, one aquatic insect genome would be sequenced for every ~9 terrestrial insect genomes. Instead, ~24 terrestrial insect genomes have been sequenced for every aquatic insect genome. A lack of aquatic genomes is limiting research progress in the field at both fundamental and applied scales. We argue that the limited availability of aquatic insect genomes is not due to practical limitations—small body sizes or overly complex genomes—but instead reflects a lack of research interest. We call for targeted efforts to expand the availability of aquatic insect genomic resources to empower future research.

Nat. Croat., Vol. 26, No. 2., 197-204, Zagreb, 2017. We collected adult caddisfly specimens with entomological nets and ultraviolet light traps monthly from May to November 2012 in Brezne Lake situated in Dragash Municipality. During this investigation we found the Leptocerid species Triaenodes bicolor for the first time in Kosovo; it is also the first record for Ecoregion 6, Hellenic Western Balkans. Additionally, this is the first record of the genus Triaenodes from Kosovo. In total seven males and three females of this species were found. Triaenodes bicolor is present all over the European continent but has been rarely sampled in southeastern Europe. Other taxa sympatric with Triaenodes bicolor in the investigated locality are: Hydropsyche instabilis, Hydropsyche spp., Plectrocnemia conspersa, Plectrocnemia spp., Micropterna nycterobia, Micropterna sequax, Limnephilus vittatus, Limnephilus auricula and Thremma anomalum.

  • In Memory of Tomáš Soldán (9 November 1951 – 13 August 2018)
    Published December 27, 2018 Klapalekiana, 54: 303–323, 2018 ISSN 1210-6100 Vzpomínka na Tomáše Soldána (9. listopadu 1951 – 13. srpna 2018) In memory of Tomáš Soldán (9 November 1951 – 13 August 2018) V pondělí 13. srpna 2018 odešla výrazná osobnost české entomologie, profesor Tomáš Soldán. Zemřel po krátké nemoci ve věku nedožitých 67 let. Tomáše Soldána zajímala zoologie, respekti- ve entomologie, již od dětství. Po absolvování Gymnázia Botičská směřovaly jeho kroky na Přírodovědeckou fakultu Univerzity Kar- lovy. V té době zde působili vynikající učitelé a entomologové, jako Karel Hůrka, Milan Chvála nebo Pavel Štys. Možná právě jejich přístup k vedení studentů a skvělé přednášky Pavla Štyse o morfologii hmyzu ovlivnily i bu- doucí směřování Tomáše Soldána. Po ukončení studia a absolvování povinné vojenské služby nastoupil Tomáš v létě 1975 na Oddělení morfologie hmyzu Entomolo- gického ústavu ČSAV, který v té době sídlil ve Viničné ulici v Praze.

  • THE CONTRIBUTION of HEADWATER STREAMS to BIODIVERSITY in RIVER Networksl
    JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION Vol. 43, No.1 AMERICAN WATER RESOURCES ASSOCIATION February 2007 THE CONTRIBUTION OF HEADWATER STREAMS TO BIODIVERSITY IN RIVER NETWORKSl Judy L. Meyer, David L. Strayer, J. Bruce Wallace, Sue L. Eggert, Gene S. Helfman, and Norman E. Leonard2 ABSTRACT: The diversity of life in headwater streams (intermittent, first and second order) contributes to the biodiversity of a river system and its riparian network. Small streams differ widely in physical, chemical, and biotic attributes, thus providing habitats for a range of unique species. Headwater species include permanent residents as well as migrants that travel to headwaters at particular seasons or life stages. Movement by migrants links headwaters with downstream and terrestrial ecosystems, as do exports such as emerging and drifting insects. We review the diversity of taxa dependent on headwaters. Exemplifying this diversity are three unmapped headwaters that support over 290 taxa. Even intermittent streams may support rich and distinctive biological communities, in part because of the predictability of dry periods. The influence of headwaters on downstream systems emerges from their attributes that meet unique habitat requirements of residents and migrants by: offering a refuge from temperature and flow extremes, competitors, predators, and introduced spe­ cies; serving as a source of colonists; providing spawning sites and rearing areas; being a rich source of food; and creating migration corridors throughout the landscape. Degradation and loss of headwaters and their con­ nectivity to ecosystems downstream threaten the biological integrity of entire river networks. (KEY TERMS: biotic integrity; intermittent; first-order streams; small streams; invertebrates; fish.) Meyer, Judy L., David L.

Editors in charge: Gavin Svenson & Klaus-Dieter Klass Abstract Within the genus Leuctra (Plecoptera: Leuctridae) the L. inermis species group comprises 17 – 18 species in which males lack the char- acteristic tergal abdominal ornamentation of many Leuctra species, and females have an accessory receptacle in the dorsal portion of the vagina. Taxonomically the group is challenging, and congruence of existing morphological species concepts and phylogenetic relationships of taxa is hitherto not assessed. Here, we estimate phylogenetic relations of morphologically defined species by concatenated maximum likelihood (ML) and Bayesian combined species tree and species delimitation analysis. We aim to clarify the status of 15 European species of the L.
