River Ribble sheep dip incident September 1997. Electric-fishing survey report

This report summarises the findings of a series of electric-fishing surveys carried out at four sites on the River Ribble from September 1997 to September 1998. The aims of these surveys were to assess the impact on juvenile salmonids of a pollution incident involving Synthetic Pyrethrin (SP) that occurred near High Birkwith I (SD 802 767) in September 1997.One of these sites was 2.65km upstream of the pollution whilst the remaining three were at varying distances downstream. Data was collected during surveys of the River Ribble in 1992, 97 and 98. The 1997 and 1998 surveys were carried out specifically to monitor for any possible effects of the SP discharge. Data are shown as grades derived from the National Fisheries Classification scheme (NFC). Results are given for the four salmonid life stages; 0+ trout, >0+ trout, 0+ salmon, >0+ salmon and also Total Salmonids.

Ancient DNA from South-East Europe Reveals Different Events during Early and Middle Neolithic Influencing the European Genetic Heritage

The importance of the process of Neolithization for the genetic make-up of European populations has been hotly debated, with shifting hypotheses from a demic diffusion (DD) to a cultural diffusion (CD) model. In this regard, ancient DNA data from the Balkan Peninsula, which is an important source of information to assess the process of Neolithization in Europe, is however missing. In the present study we show genetic information on ancient populations of the South-East of Europe. We assessed mtDNA from ten sites from the current territory of Romania, spanning a time-period from the Early Neolithic to the Late Bronze Age. mtDNA data from Early Neolithic farmers of the Starcevo Cris culture in Romania (Carcea, Gura Baciului and Negrilesti sites), confirm their genetic relationship with those of the LBK culture (Linienbandkeramik Kultur) in Central Europe, and they show little genetic continuity with modern European populations. On the other hand, populations of the Middle-Late Neolithic (Boian, Zau and Gumelnita cultures), supposedly a second wave of Neolithic migration from Anatolia, had a much stronger effect on the genetic heritage of the European populations. In contrast, we find a smaller contribution of Late Bronze Age migrations to the genetic composition of Europeans. Based on these findings, we propose that permeation of mtDNA lineages from a second wave of Middle-Late Neolithic migration from North-West Anatolia into the Balkan Peninsula and Central Europe represent an important contribution to the genetic shift between Early and Late Neolithic populations in Europe, and consequently to the genetic make-up of modern European populations.

Variações cranianas em Tursiops truncatus (Mammalia: Certartiodactyla) em diferentes localidades dos oceanos, com ênfase na costa sul-americana: uma abordagem pela técnica de morfometria geométrica

Os delfinídeos são os cetáceos mais ecologicamente diversos, ocorrendo numa ampla faixa de latitudes, em águas oceânicas e costeiras, incluindo regiões estuarinas e dulcícolas. O cenário taxonômico é especialmente confuso no gênero Tursiops, uma vez que grande parte das formas tem sido sinonimizadas na espécie Tursiopstruncatus. No entanto, estudos recentes sugerem que o gênero Tursiops seja polifilético. O golfinho-nariz-de-garrafa,T.truncatus, ocorre tanto em águas costeiras quanto oceânicas, em todas as regiões tropicais e temperadas. A espécie T. truncatus é tida como polimórfica e tal característica a torna alvo de acirradas discussões acerca do que são variações regionais ou diferentes entidades taxonômicas. O objetivo do presente estudo foi analisar a variabilidade morfológica de T. truncatus em distintas regiões oceânicas, buscando fornecer informações que permitam embasar os argumentos para futuras discussões taxonômicas que envolvem o gênero. Para isso, foi feita análise de Morfometria Geométrica em 2-D de crânios em vistas dorsal e lateral de espécimes que ocorrem nos oceanos Pacífico Norte Oriental, Atlântico Norte Ocidental, Atlântico Sul Ocidental, Atlântico Norte Oriental, Atlântico Sul Oriental e Índico. Foram encontradas diferenças significativas em todo o material analisado, incluindo diferenças entre exemplares reconhecidos como T. gephyreus e T. truncatus na costa Atlântica da América do Sul. As variações cranianas encontradas possuem relação com o tipo de ambiente em que os diferentes grupos ocorrem e podem estar relacionadas com a forma de forrageio, captura de presa e ao sistema de ecolocalização. Além disso, as variações na costa Atlântica da América do Sul podem ser explicadas pelo possível reconhecimento de duas espécies nessa região
