MacLean1 Abstract Collections of aquatic invertebrates from the Grand Portage Indian Res- ervation (Cook County, Minnesota) during 2001 – 2012 resulted in 9 families, 43 genera and 112 species of aquatic and semiaquatic Coleoptera. The Dytisci- dae had the most species (53), followed by Hydrophilidae (20), Gyrinidae (14), Haliplidae (8), Chrysomelidae (7), Elmidae (3) and Curculionidae (5). The families Helodidae and Heteroceridae were each represented by a single spe- cies. Seventy seven percent of species were considered rare or uncommon (1 - 10 records), twenty percent common (11 - 100 records) and only three percent abundant (more than 100 records).

  • Coleoptera: Dytiscidae) Rasa Bukontaite1,2*, Kelly B Miller3 and Johannes Bergsten1
    Bukontaite et al. BMC Evolutionary Biology 2014, 14:5 http://www.biomedcentral.com/1471-2148/14/5 RESEARCH ARTICLE Open Access The utility of CAD in recovering Gondwanan vicariance events and the evolutionary history of Aciliini (Coleoptera: Dytiscidae) Rasa Bukontaite1,2*, Kelly B Miller3 and Johannes Bergsten1 Abstract Background: Aciliini presently includes 69 species of medium-sized water beetles distributed on all continents except Antarctica. The pattern of distribution with several genera confined to different continents of the Southern Hemisphere raises the yet untested hypothesis of a Gondwana vicariance origin. The monophyly of Aciliini has been questioned with regard to Eretini, and there are competing hypotheses about the intergeneric relationship in the tribe. This study is the first comprehensive phylogenetic analysis focused on the tribe Aciliini and it is based on eight gene fragments. The aims of the present study are: 1) to test the monophyly of Aciliini and clarify the position of the tribe Eretini and to resolve the relationship among genera within Aciliini, 2) to calibrate the divergence times within Aciliini and test different biogeographical scenarios, and 3) to evaluate the utility of the gene CAD for phylogenetic analysis in Dytiscidae. Results: Our analyses confirm monophyly of Aciliini with Eretini as its sister group. Each of six genera which have multiple species are also supported as monophyletic. The origin of the tribe is firmly based in the Southern Hemisphere with the arrangement of Neotropical and Afrotropical taxa as the most basal clades suggesting a Gondwana vicariance origin. However, the uncertainty as to whether a fossil can be used as a stem-or crowngroup calibration point for Acilius influenced the result: as crowngroup calibration, the 95% HPD interval for the basal nodes included the geological age estimate for the Gondwana break-up, but as a stem group calibration the basal nodes were too young.

This survey was to mirror the locations and methodology of a previous survey undertaken during autumn 2016 and spring 2017. Colin Plant Associates also undertook the aquatic invertebrate sampling of this previous survey. 1.1.2 The 2016-17 aquatic survey was commissioned with the primary objective of establishing a baseline aquatic invertebrate species inventory and to determine the quality of the aquatic habitats present across both the Nature Reserve and Southern Marsh areas of the Crossness Sewage Treatment Works. The surveyors were asked to sample at twenty-four, pre-selected sample station locations, twelve in each area. Aquatic Coleoptera and Heteroptera (beetles and true bugs) were selected as target groups. A report of the previous survey was submitted in Sept 2017 (Plant 2017). 1.1.3 During December 2017 a large-scale pollution event took place and untreated sewage escaped into a section of the Crossness Nature Reserve. The primary point of egress was Nature Reserve Sample Station 1 (NR1) though because of the connectivity of much of the waterbody network on the marsh other areas were affected.
