  • Crossness Sewage Treatment Works Nature Reserve & Southern Marsh Aquatic Invertebrate Survey
    Commissioned by Thames Water Utilities Limited Clearwater Court Vastern Road Reading RG1 8DB CROSSNESS SEWAGE TREATMENT WORKS NATURE RESERVE & SOUTHERN MARSH AQUATIC INVERTEBRATE SURVEY Report number: CPA18054 JULY 2019 Prepared by Colin Plant Associates (UK) Consultant Entomologists 30a Alexandra Rd London N8 0PP 1 1 INTRODUCTION, BACKGROUND AND METHODOLOGY 1.1 Introduction and background 1.1.1 On 30th May 2018 Colin Plant Associates (UK) were commissioned by Biodiversity Team Manager, Karen Sutton on behalf of Thames Water Utilities Ltd. to undertake aquatic invertebrate sampling at Crossness Sewage Treatment Works on Erith Marshes, Kent. 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.

  • An Interspecific Test of Bergmann's Rule Reveals Inconsistent Body Size
    Ecological Entomology (2019), 44,249–254 DOI:10.1111/een.12701 An interspecific test of Bergmann’s rule reveals inconsistent body size patterns across several lineages of water beetles (Coleoptera: Dytiscidae) SUSANA PALLARÉS,1 MICHELE LAI,2 PEDRO ABELLÁN,3 IGNACIO RIBERA4 and D AV I D S Á N C H E Z - F E R N Á N D E Z 1 1Instituto de Ciencias Ambientales, Universidad de Castilla-La Mancha, Toledo, Spain, 2Università degli Studi di Cagliari, Cagliari, Italy, 3Departmento de Zoología, Universidad de Sevilla, Sevilla, Spain and 4Institut de Biologia Evolutiva (CSIC-Universitat Pompeu Fabra), Barcelona, Spain Abstract. 1. Bergmann’s rule sensu lato,theecogeographicpatternrelatinganimals’ body size with environmental temperature (or latitude), has been shown to be inconsis- tent among insect taxa. Body size clines remain largely unexplored in aquatic insects, which may show contrasting patterns to those found in terrestrial groups because of the physiological or mechanical constraints of the aquatic environment. 2. Bergmann’s rule was tested using data on body size, phylogeny and distribution for 93 species belonging to four lineages of dytiscid water beetles. The relationship between size and latitude was explored at two taxonomic resolutions – within each independent lineage, and for the whole dataset – employing phylogenetic generalised least-squares to control for phylogenetic inertia. The potential infuence of habitat preference (lotic versus lentic) on body size clines was also considered. 3. Within-lineage analyses showed negative relationships (i.e. converse Bergmann’s rule), but only in two lineages (specifcally in those that included both lotic and lentic species). By contrast, no relationship was found between body size and latitude for the whole dataset.

This pool is shown in Fig 4 on p 25 of Latissimus 29. When I removed the abdomen, in colchicine solution in insect saline (for chromosome preparation) what appeared to a mass of tiny bubbles appeared. My first thought was that I had foolishly opened the beetle in alcoholic fixative, but this was disproved when the “bubbles” began swimming around in a manner characteristic of ciliary locomotion. At the time I was not able to do anything with them, but it was something the like of which I had never seen before. Then, as luck would have it, on Tuesday Max Barclay brought back from the Moscow region of Russia a single living male Hydrobius rottenbergii Gerhardt. This time I injected the beetle with colchicine solution and did not open it up (remove the abdomen) till I had transferred it to ½-isotonic potassium chloride. And at this stage again I was confronted with a mass of the same self-propelled “bubbles”.

ZooKeys 813: 21–38. https://doi.org/10.3897/zookeys.813.29765 Abstract Iberoporus pluto sp. n., the first stygobiont beetle from Portugal (Dytiscidae, Hydroporinae), is described from a single female from the cave Soprador do Carvalho (Coimbra). The species is highly troglomorphic, depigmented, blind, and with elongated appendages not adapted for swimming. A molecular phylogeny based on a combination of three mitochondrial and two nuclear genes showed the new species to be sister to I. cermenius Castro & Delgado, 2001 from Córdoba (south of Spain), within the subtribe Siettitiina of the tribe Hydroporini. Both species are included in a clade with Siettitia avenionensis Guignot, 1925 (south of France) and Rhithrodytes agnus Foster, 1992 and R.

Ent. Zool. Vol. 10, No. 1, January 2015___________ Scope: Munis Entomology & Zoology publishes a wide variety of papers on all aspects of Entomology and Zoology from all of the world, including mainly studies on systematics, taxonomy, nomenclature, fauna, biogeography, biodiversity, ecology, morphology, behavior, conservation, paleobiology and other aspects are appropriate topics for papers submitted to Munis Entomology & Zoology. Submission of Manuscripts: Works published or under consideration elsewhere (including on the internet) will not be accepted. At first submission, one double spaced hard copy (text and tables) with figures (may not be original) must be sent to the Editors, Dr. Hüseyin Özdikmen for publication in MEZ. All manuscripts should be submitted as Word file or PDF file in an e-mail attachment. If electronic submission is not possible due to limitations of electronic space at the sending or receiving ends, unavailability of e-mail, etc., we will accept “hard” versions, in triplicate, accompanied by an electronic version stored in a floppy disk, a CD-ROM. Review Process: When submitting manuscripts, all authors provides the name, of at least three qualified experts (they also provide their address, subject fields and e-mails). Then, the editors send to experts to review the papers. The review process should normally be completed within 45-60 days. After reviewing papers by reviwers: Rejected papers are discarded. For accepted papers, authors are asked to modify their papers according to suggestions of the reviewers and editors.

Assemblages of Coleoptera, shallow lakes, environmental variables, Iberian Peninsula, multivariate analysis. Abstract. Aquatic Coleoptera in shallow lakes associated with the Canal de Castilla (Palencia Province, Spain) in the northern Ibe­ rian Meseta were sampled over the course of a year (spring 1998-winter 1999). These waterbodies are typical plateau wetlands with dense vegetation and vary in permanence and area (from 3.3 ha to 29.35 ha). Oxygen concentration, conductivity and pH were recorded at the time of sampling. Lake area, depth, water permanence and type of vegetation were also taken into account. Ninety two species were collected. Species richness was high in comparison with other wetlands in Spain. The assemblage structure was assessed in terms of three community parameters: richness, abundance and diversity (Shannon index). Their relationships with envi­ ronmental variables were explored using correlation coefficients. The assemblage composition was analysed by multivariate tech­ niques. First, the sites were classified by means of TWINSPAN. The presence of each species in the different TWINSPAN groups was used to assess their habitat preferences.
