    Thoughts on Water Beetles in a Mediterranean Environment

    The chapter provides data from a survey carried out on water beetles in various freshwater ecosystems in Tunisia as a Mediterranean country of considerable diversity. Studies dealing with these insects are fragmentary not only in comparison with the European fauna but also in comparison to other zoogeographical areas. A compiled checklist of beetle species collected from Tunisia is given with an insight on new recorded species. Diversity, altitudinal distribution, and geographical pattern of water beetles in Northern Tunisia are discussed with regard to other Mediterranean areas. They include various chorotypes related to the history of the Mediterranean basin. Several species are threatened and require conservation. According to the criteria of the IUCN, several water beetle species can be included in the list of threatened species

    Effect of Heavy Metal Pollution on Invertebrates

    Get PDF
    Metal pollutants are widespread in air, soil and water causing a decline in invertebrates worldwide. The increase of environmental pollution by heavy metals has a negative impact to organisms and influence their diversity, distribution, physiology and behavior. Contrary to other pollutants, metals are non-degradable and can potentially bio-accumulate and be biomagnified in the trophic chain. Because soil invertebrates tend to be strongly affected by environmental disturbances, high concentrations of these metals can become hazardous to invertebrates. Noxious effects can affect all biological levels, and toxins affect all ecological interactions. In this brief chapter, we have tried to develop a comprehensive understanding of the influence of metal contamination on ecosystem disturbance. We give examples of studies on the effects of pollutants on invertebrates

    The family Carabidae (Coleoptera) is one of the largest families of beetles. In Tunisia it has not been studied thoroughly. In the following paper, the material of Carabidae collected during expeditions to some regions of Tunisia between 2012 and 2013 was studied. Species belonging to 15 genera and 3 subfamilies were collected in seven different localities.La familia Carabidae (Coleoptera) es una de las mayores familias de escarabajos. En Túnez no se ha estudiado a fondo. En el siguiente documento es ha estudiado el material de Carabidae recogido durante las expediciones a algunas regiones de Túnez entre 2012 y 2013. Se capturaron especies pertenecientes a 15 géneros y 3 subfamilias en siete localidades diferentes

    In this study, Hydrochus species known from Tunisia are presented with their distribution in Tunisia and in the rest of the world. Of these, Hydrochus smaragdineus Faimaire, 1879, is recorded in Tunisia for the first time and all species were identified according to our specimens captured in some streams located in the north of Tunisia. A key of species and some ecological data are included.Etude des Hydrochus Leach, 1817, de Tunisie (Coleoptera, Hydrochidae).

    New data on the family Hydraenidae Mulsant, 1844, from Tunisia (Coleoptera). The present paper on the Hydraenidae Mulsant, 1844, deals with a checklist of the collected species from the streams of the northern Tunisia with their distribution in the study area and their biogeography. This list includes four species recorded for the first time in Tunisia : Hydraena (H.) atrata Desbrochers des Loges, Hydraena (H.) scabrosa d''Orchymont, Ochthebius (O.) mauretanicus Jäch and Ochthebius (O.) mediterraneus Ienistea. According to the criteria of the IUCN (2006), we suggest the inclusion of H. kroumiriana in the national red list of protected species.Le présent travail sur la famille des Hydraenidae Mulsant, 1844, comporte une liste des espèces collectées dans les cours d'eau de Tunisie septentrionale, avec leur distribution dans la zone d''étude et leur biogéographie.
