They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live in subterranean habitats. Using 30 m2 transects, the invertebrate fauna was collected and the substrate features were measured. The results showed that community responded to the presence of guano, cobbles, boulders, and substrate heterogeneity. The positive relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for structuring invertebrate cave communities in Guatemalan caves. -

ITE contributes to, and draws upon, the collective knowledge of the 13 sister institutes which make up the Natural Environment Research Council, spanning all the environmental sciences. The Institute studies the factors determining the structure, composition and processes of land and freshwater systems, and of individual plant and animal species. It is developing a sounder scientific basis for predicting and modelling environmental trends arising from natural or man- made change. The results of this research are available to those responsible for the protection, management and wise use of our natural resources. One quarter of ITE's work is research commissioned by customers, such as the Department of Environment, the European Economic Community, the Nature Conservancy Council and the Overseas Development Administration. The remainder is fundamental research supported by NERC. ITE's expertise is widely used by international organizations in overseas projects and programmes of research. -

Avda. Francisca Millán Serrano, 37; 50012 Zaragoza [email protected] 1. Breve definición del grupo y principales caracteres diagnósticos El orden Poecilostomatoida Thorell, 1859 tiene una posición sistemática discutida. Tradicionalmente ha sido considerado un orden independiente, dentro de los 10 que conforman la subclase Copepoda; no obstante, algunos autores consideran que no existen diferencias suficientes respeto al orden Cyclopoida, del que vendrían a ser un suborden (Stock, 1986 o Boxshall & Halsey, 2004, entre otros). No obstante, en el presente volumen se ha considerado un orden independiente y válido. Antes de entrar en las singularidades del orden es preciso tratar sucintamente la morfología, ecolo- gía y biología de Copepoda, lo que se realiza en los párrafos siguientes. 1.1. Introducción a Copepoda Los copépodos se encuentran entre los animales más abundantes en número de individuos del planeta. El plancton marino puede alcanzar proporciones de un 90 por ciento de copépodos respecto a la fauna total presente. Precisamente por su número y a pesar de su modesto tamaño (forman parte de la micro y meiofauna) los copépodos representan una papel fundamental en el funcionamiento de los ecosistemas marinos. En su mayor parte son especies herbívoras –u omnívoras– y por lo tanto transformadoras de fito- plancton en proteína animal que, a su vez, sirve de alimento a todo un ejército de especies animales, inclu- yendo gran número de larvas de peces. -

Zusammenfassung Die vorliegende Arbeit hat sich zum Ziel gesetzt, den Populationskomplex der hawai’ischen Höhlenzikade Oliarus polyphemus als Modellsystem für das Stu- dium schneller Artenbildungsprozesse zu erschließen. Dazu wurde ein theoretischer Rahmen aus Konzepten und daraus abgeleiteten Hypothesen zur Interpretation be- kannter Fakten und Erhebung neuer Daten entwickelt. Im Laufe der Studie wurde zur Erfassung geografischer Muster ein GIS (Geographical Information System) erstellt, das durch Einbeziehung der historischen Geologie eine präzise zeitliche Einordnung von Prozessen der Habitatsukzession erlaubt. Die Muster der biologi- schen Differenzierung der Populationen wurden durch morphometrische, etho- metrische (bioakustische) und molekulargenetische Methoden erfasst. -
APPENDIX 1 Classified List of Fishes Mentioned in the Text, with Scientific and Common Names
APPENDIX 1 Classified list of fishes mentioned in the text, with scientific and common names. ___________________________________________________________ Scientific names and classification are from Nelson (1994). Families are listed in the same order as in Nelson (1994), with species names following in alphabetical order. The common names of British fishes mostly follow Wheeler (1978). Common names of foreign fishes are taken from Froese & Pauly (2002). Species in square brackets are referred to in the text but are not found in British waters. Fishes restricted to fresh water are shown in bold type. Fishes ranging from fresh water through brackish water to the sea are underlined; this category includes diadromous fishes that regularly migrate between marine and freshwater environments, spawning either in the sea (catadromous fishes) or in fresh water (anadromous fishes). Not indicated are marine or freshwater fishes that occasionally venture into brackish water.

Matt Longshaw & Stephen Feist Cefas Weymouth Laboratory Barrack Road, The Nothe, Weymouth, Dorset DT4 8UB 1. Introduction This review provides a summary of the parasites, pathogens and contaminant related impacts on deep sea fish normally found at depths greater than about 200m There is a clear focus on worldwide commercial species but has an emphasis on records and reports from the north east Atlantic. In particular, the focus of species following discussion were as follows: deep-water squalid sharks (e.g. Centrophorus squamosus and Centroscymnus coelolepis), black scabbardfish (Aphanopus carbo) (except in ICES area IX – fielded by Portuguese), roundnose grenadier (Coryphaenoides rupestris), orange roughy (Hoplostethus atlanticus), blue ling (Molva dypterygia), torsk (Brosme brosme), greater silver smelt (Argentina silus), Greenland halibut (Reinhardtius hippoglossoides), deep-sea redfish (Sebastes mentella), alfonsino (Beryx spp.), red blackspot seabream (Pagellus bogaraveo). However, it should be noted that in some cases no disease or contaminant data exists for these species. -

Invertebrate Monitoring As Measure of Ecosystem Change Mélissa Jane
Invertebrate monitoring as measure of ecosystem change Mélissa Jane Houghton B. Arts and Sciences M. Environmental Management A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2020 School of Biological Sciences Centre for Biodiversity and Conservation Science Abstract Islands and their biodiversity have high conservation value globally. Non-native species are largely responsible for island extinctions and island ecosystem disruption and are one of the major drivers of global biodiversity loss. Developing tools to effectively measure and understand island ecosystem change is therefore vital to future island conservation management, specifically island communities and the threatened species within them. One increasing utilised island conservation management tool is invasive mammal eradication. Such programs are increasing in number and success, with high biodiversity gains. Typically, it is assumed that the removal of target non-native species equates to management success and in some instances, recovery of a key threatened or charismatic species affected by the pest species are monitored. Yet to date, there are few published studies quantifying post- eradication ecosystem responses. Such monitoring helps to calculate return-on-investment, understand the conservation benefits of management and inform conservation decision- making associated with current and future restoration programs. Not only are there few studies providing empirical evidence of whole-of-ecosystem recovery following mammal eradications, -

They live in association with par ticular hosts and exhibit various reductive tendencies (Gotto, 1979; Kabata, 1979). The reductive tendencies often appear as simplification and/or reduction of adult appendages, which have been considered as important key characters in their tax onomy and phylogeny (notably Wilson, op. cit.; Kabata, op. cit.). Larval morpholo gy has not been taken into taxonomic and phylogenetic consideration. This is par ticularly unfortunate when dealing with the poecilostome Cyclopoida, which include many species with transformed adults. Our knowledge on the ontogeny of the Copepoda have been accumulated through the efforts of many workers (see refer ences), but still it covers only a small part of the Copepoda. History of study on the nauplii of parasitic copepods goes back to the 1830's, as seen in the description of a nauplius of Lernaea (see Nordmann, 1832). I have been studying the ontogeny of the parasitic and semi-parasitic Copepoda since 1969 and have reported larval stages of various species (Izawa, 1969; 1973; 1975; 1986a, b). -
Checklist of the Terrestrial Isopods of the New World (Crustacea, Isopoda, Oniscidea)
Checklist of the terrestrial isopods of the new world (Crustacea, Isopoda, Oniscidea) Andreas Leistikow 1,2 Johann Wolfgang Wagele 2 ABSTRACT. A check-list of all the American Oniscidea known to the authors and their quotation in literature is presented. The species account comprises notes on species' distribution and a revise d synonymy. As far as possible comments on taxonomic problems are given. The species are ascribed to the families which are commonly recognised, despite many of them are paraphyletic constructions. This check-list should support the work of both ecologists and ta xonomist when dealing with New World Oniscidea. KEY WORDS. Tsopoda, American Oniscidea, taxonomy, biodiversity, check-list The suborder Oniscidea is one of the most important within the Isopoda with almost half of all known species of Isopoda belonging to it. The members of Oniscidea play an important role in terrestrial ecosystems, especially in the tropics. They are destruents occurring in great numbers and so me we re able to adapt to man. Therefore, they became anthropophilous and are cosmopolitically di stributed like Porcellionides pruinosus (Brandt, 1833) and Cubaris //'Iurina Brandt, 1833. A first attempt to review the distributional patterns of Oniscidea had been made by VANDEL (1945), but until thi s time the knowledge on the distribution and diversity of terrestrial isopoda has increased considerably in the last decades. Unfortunately, there are no new monographic works on the suborder. At least, there are check- li sts on Oniscidea from Oceania (JACKSON 1941) and Ati'ica south of the Sahara (FERRARA & TAITI 1978). For the Americas, the last review on fresh water and terrestrial iso pods was undertaken by V AN NAME (\936, 1940, 1942).
