Auswirkungen von Mikroplastik auf die Grünlippmuschel Perna by Sinja Rist

By Sinja Rist

Sinja
Rist untersucht die Auswirkungen von Mikroplastik, das in marinen Sedimenten
weltweit verbreitet ist, auf die Grünlippmuschel Perna viridis. Sie zeigt, dass
nach einer 6-wöchigen Exposition im exertions mit steigender Partikelzahl starke
Einschränkungen physiologischer Funktionen wie Filtration, Atmung, Bewegung und
Byssusproduktion sowie eine erhöhte Mortalität auftreten. Signifikante Effekte
waren dabei schon bei geringen Partikelmengen messbar. Insgesamt lassen die
Ergebnisse dieser Studie auf eine deutliche Dezimierung der Energiereserven der
Muscheln schließen. Die Kontamination der Partikel mit dem organischen
Schadstoff Fluoranthen hatte dagegen keinen eindeutig messbaren Effekt auf die
Tiere. Diese Studie verdeutlicht, dass im Angesicht einer steigenden
Mikroplastikbelastung benthischer Habitate mit diversen Auswirkungen auf die
Organismen gerechnet werden muss.

The Evolution of Exudativory in Primates (Developments in by Anne M. Burrows,Leanne T Nash

By Anne M. Burrows,Leanne T Nash

I first turned curious about study into primate habit and ecology in 1968, over forty years in the past, pushed via a quest for a greater realizing of the average context of primate evolution. at the moment, it used to be almost unknown that primates can take advantage of exudates as an immense nutrition resource. i used to be definitely blind to this myself. by means of success, i used to be presented a postdoctoral furnish to paintings on lemurs with Jean-Jacques Petter within the normal ecology department of the Muséum nationwide d’Histoire Naturelle in Brunoy, France. This supplied the launching-pad for my first box research of lesser mouse lemurs in Madagascar, in which I received my preliminary inklings of exudate feeding. It used to be additionally in Brunoy that I met up with Pierre Charles- Dominique, who brought me to pioneering observations of exudate feeding he had made in the course of his box research of 5 lorisiform species in Gabon. This opened my eyes to a key feeding edition that has now been stated for a minimum of sixty nine primate species in 12 households (Smith, Chap. three) – virtually 20% of extant primate species. So exudativory is now firmly validated as a nutritional classification for p- associates, along the long-recognized sessions of faunivory (including insectivory), frugivory, and folivory. quickly after I encountered Charles-Dominique, he released the 1st artificial account of his Gabon box learn in a French language magazine (Charles-Dominique 1971).

Macrophytes in Aquatic Ecosystems: From Biology to by J.M. Caffrey,A. Dutartre,J. Haury,K.M. Murphy,P.M. Wade

By J.M. Caffrey,A. Dutartre,J. Haury,K.M. Murphy,P.M. Wade

Macrophytes and macrophytes ecology have received an additional significance with the creation of, and criminal requirement to enforce, the ecu Water Framework Directive. This displays the precious function that aquatic plant groups play in assessing the ecological prestige of water our bodies. major alterations within the prestige and basic abundance of those groups has been recorded within the final 3 a long time, consequent on such elements as international warming and, more and more, at the unfold of competitive alien species. those adjustments were such a lot felt in these waters which are exploited for amenity and leisure targets. The elevated biomass of aquatic crops in water our bodies has adversely impacted on relaxation use of those structures but additionally on their use for agricultural, flood aid, municipal and family reasons. The loss to nationwide economies due to this over the top plant biomass has been considerable and has placed strain on water managers to strengthen weed keep an eye on systems which are effective, environmentally delicate and low-budget. the consequences from the main up to date learn actions and box trials of best aquatic plant scientists and executives in all 5 continents, geared toward resolving those weed difficulties, has been drawn jointly during this quantity. The identify of this distinctive factor, 'Macrophytes in aquatic ecosystems: from biology to management', is wide-ranging and displays the vast scope and scale of the papers awarded therein. It additional recognises the previous paradigm: 'knowledge to accomplish administration and administration to accomplish knowledge'.
