The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20%
The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20% Ben Rowson1*, Roy Anderson2, James A. Turner1, William O. C. Symondson3 1 National Museum of Wales, Cardiff, Wales, United Kingdom, 2 Conchological Society of Great Britain & Ireland, Belfast, Northern Ireland, United Kingdom, 3 Cardiff School of Biosciences, Cardiff University, Cardiff, Wales, United Kingdom Abstract The slugs of Britain and Ireland form a well-studied fauna of economic importance. They include many widespread European species that are introduced elsewhere (at least half of the 36 currently recorded British species are established in North America, for example). To test the contention that the British and Irish fauna consists of 36 species, and to verify the identity of each, a species delimitation study was conducted based on a geographically wide survey. Comparisons between mitochondrial DNA (COI, 16S), nuclear DNA (ITS-1) and morphology were investigated with reference to interspecific hybridisation. Species delimitation of the fauna produced a primary species hypothesis of 47 putative species. This was refined to a secondary species hypothesis of 44 species by integration with morphological and other data. Thirty six of these correspond to the known fauna (two species in Arion subgenus Carinarion were scarcely distinct and Arion (Mesarion) subfuscus consisted of two near-cryptic species). However, by the same criteria a further eight previously undetected species (22% of the fauna) are established in Britain and/or Ireland. Although overlooked, none are strictly morphologically cryptic, and some appear previously undescribed. Most of the additional species are probably accidentally introduced, and several are already widespread in Britain and Ireland (and thus perhaps elsewhere). -

AN ABSTRACT OF THE THESIS OF Nilton Eduardo Deza Arroyo for the degree of Master of Science in Fisheries Science presented on November 8. 1996. Title: Mercury Accumulation in Fish from Madre de Dios. a Goidmining Area in the Amazon Basin. Peru Redacted for Privacy Abstract approved: I. Weber Redacted for Privacy Wayne K. Seim In this study mercury contamination from goldmining was measured in tissues of fish from Madre de Dios, Amazonia, Peru.Bioaccumulation, biomagnification, the difference in mercury burden among residential and migratory species, and comparison between fish from Puerto Maldonado (a goidmining area) and Manu (a pristine area) were examined. Samples of dorsal-epaxial muscle of dorado (Brachyplatystoma flavicans); fasaco (Hoplias malabaricus),bothcarnivores;boquichico(Prochilodusnigricans),a detritivore;mojarita (Bryconopsaffmelanurus),an insectivore;and carachama (Hypostomus sp.), an detntivore; were analyzed by using the flameless cold vapor atomic absorption spectrophotometry technique. Dorado, a top predator, displayed the highest values of total mercury (699 ugfKg ± 296).Six out of ten dorados showed an average higher than safe values of 0.5 ug/g (WHO, 1991). Lower values reported in this study in the other species suggest that dorado may have gained its mercury burden downstream of Madre de Dios River, in the Madeira River, where goidmining activities are several times greater than that in the Madre de Dios area. Fasaco from Puerto Maldonado displayed higher levels than fasaco from Manu; however, mercury contamination in Puerto Maldonado is lower than values reported for fish from areas with higher quantities of mercury released into the environment. Positive correlation between mercury content and weight of fish for dorado, fasaco and boquichico served to explain bioaccumulation processes in the area of study. -
On the Distribution and Food Preferences of Arion Subfuscus (Draparnaud, 1805)
Vol. 16(2): 61–67 ON THE DISTRIBUTION AND FOOD PREFERENCES OF ARION SUBFUSCUS (DRAPARNAUD, 1805) JAN KOZ£OWSKI Institute of Plant Protection, National Research Institute, W³adys³awa Wêgorka 20, 60-318 Poznañ, Poland (e-mail: [email protected]) ABSTRACT: In recent years Arion subfuscus (Drap.) is increasingly often observed in agricultural crops. Its abun- dance and effect on winter oilseed rape crops were studied. Its abundance was found to be much lower than that of Deroceras reticulatum (O. F. Müll.). Preferences of A. subfuscus to oilseed rape and 19 other herbaceous plants were determined based on multiple choice tests in the laboratory. Indices of acceptance (A.I.), palat- ability (P.I.) and consumption (C.I.) were calculated for the studied plant species; accepted and not accepted plant species were identified. A. subfuscus was found to prefer seedlings of Brassica napus, while Chelidonium maius, Euphorbia helioscopia and Plantago lanceolata were not accepted.

They are often described as flower pest (“Rose chafers, flower beetles”), and are thought not to be significant as fruit pests. However, during the last ten years some serious damage to fruit has been observed. Since this damage occurs when the fruits are ripening, insecticides cannot be used. There are no literature data about the amount of the damage or how to monitor the damage. This paper describes our monitoring of the population dynamics of the Cetonia aurata and Potosia cuprea, and the method for calculating the damage to fruit suitable for the orchards in this area. The study was conducted during the spring and summer of the year 2005, 2006 and 2007 in the Ravni kotari region, near the villages of Prkos and Smilčić. We used Csalomon® VARb3k funnel traps. -

Capacity building for carbon- and biodiversity-based payments for ecosystem services in the Peruvian Amazon: Case for Support Part 1 - Previous track record This proposal brings together a new consortium of UK universities and Peruvian research organisations and NGOs. The wide expertise of the team incorporates individuals involved in the measurement of forest carbon stocks and biodiversity, remote sensing of land-use change, development of payment systems for ecosystem services and the management of conservation and rural development projects. The School of Geography, University of Leeds, UK is a leading geography department in the UK. Tropical forest ecology is a major research focus and the Ecology and Global Change research cluster leads an international network of forest inventory plots (RAINFOR) to monitor patterns of C cycling in Amazonia funded by NERC, EU, Royal Geographical Society and Moore Foundation grants. Tim Baker (PI) has worked throughout Amazonia since 2001 with research interests at the interface of community and ecosystem ecology, with a focus on C cycling in tropical forests: quantifying regional-scale patterns of C stocks and long-term changes in forest structure and dynamics. His second focus is the processes that maintain the high diversity of these forests, particularly the role of disturbance, and thirdly, how the results of ecological studies can be applied to land- and resource-management in the tropics. He held a NERC research fellowship from 2005–7 and currently holds a Research Council Academic Fellowship at the University of Leeds. Relevant publications: 1. Reed, M., Dougil, A. and Baker, T.R.

It is with humbleness, then, that I must refer to the Kichwa people of Sarayaku, the large indigenous territory on the banks of the Bobonaza river in Ecuador and cite their words as the most appro- priate ethical definition of what Amazonia has been and still is for thousands of lineages of indigenous people living in harmony – in Sumak Kawsay – in this immense territory now threatened by neo- imperialist destruction. -
Matses Indian Rainforest Habitat Classification and Mammalian Diversity in Amazonian Peru
Journal of Ethnobiology 20(1): 1-36 Summer 2000 MATSES INDIAN RAINFOREST HABITAT CLASSIFICATION AND MAMMALIAN DIVERSITY IN AMAZONIAN PERU DAVID W. FLECK! Department ofEveilltioll, Ecology, alld Organismal Biology Tile Ohio State University Columbus, Ohio 43210-1293 JOHN D. HARDER Oepartmeut ofEvolution, Ecology, and Organismnl Biology Tile Ohio State University Columbus, Ohio 43210-1293 ABSTRACT.- The Matses Indians of northeastern Peru recognize 47 named rainforest habitat types within the G61vez River drainage basin. By combining named vegetative and geomorphological habitat designations, the Matses can distinguish 178 rainforest habitat types. The biological basis of their habitat classification system was evaluated by documenting vegetative ch<lracteristics and mammalian species composition by plot sampling, trapping, and hunting in habitats near the Matses village of Nuevo San Juan. Highly significant (p<:O.OOI) differences in measured vegetation structure parameters were found among 16 sampled Matses-recognized habitat types. Homogeneity of the distribution of palm species (n=20) over the 16 sampled habitat types was rejected. Captures of small mammals in 10 Matses-rc<:ognized habitats revealed a non-random distribution in species of marsupials (n=6) and small rodents (n=13). Mammal sighlings and signs recorded while hunting with the Matses suggest that some species of mammals have a sufficiently strong preference for certain habitat types so as to make hunting more efficient by concentrating search effort for these species in specific habitat types. Differences in vegetation structure, palm species composition, and occurrence of small mammals demonstrate the ecological relevance of Matses-rccognized habitat types. Key words: Amazonia, habitat classification, mammals, Matses, rainforest.

Dear Denver Zoo Supporters The role of zoos in the global conservation effort intensifies with each passing year as animals face growing pressure in their natural habitats, and experience an alarming increase in those classified as vulnerable, threatened and endangered. Zoos, particularly those accredited by the Association of Zoos & Aquariums (AZA), are called upon to help save and protect species, both within their gates and beyond. Denver Zoo has answered that call. Since 1896, we have established ourselves as a leader in the protection of wildlife, dedicating staff and funding to more than 600 conservation projects in 62 countries on six continents. -
Karyotypic Characterization of Prochilodus Mariae, Semaprochilodus Kneri Ands. Laticeps (Teleostei: Prochilodontidae) from Caica
Neotropical Ichthyology, 1(1):47-52, 2003 Copyright © 2003 Sociedade Brasileira de Ictiologia Karyotypic characterization of Prochilodus mariae, Semaprochilodus kneri and S. laticeps (Teleostei: Prochilodontidae) from Caicara del Orinoco, Venezuela Claudio Oliveira*, Mauro Nirchio**, Ángel Granado*** and Sara Levy** Fish of the family Prochilodontidae are considered one of the most important components of commercial and subsistence fishery in freshwater environments in South America. This family consists of 21 species and three genera. In the present study, the karyotypes of Prochilodus mariae, Semaprochilodus kneri, and S. laticeps from Caicara del Orinoco, Bolivar State, Venezuela were studied. The species P. mariae, S. kneri and S. laticeps exhibited 2n=54 chromosomes (40 metacentric and 14 submetacentric), a single chromosome pair with nucleolus organizer regions, and a large amount of heterochromatin found at centromeric and pericentromeric positions in almost all chromosomes. The P. mariae specimens studied displayed 0 to 3 supernumerary microchromosomes. The data obtained here confirm the conservative nature of the chromosome number and morphology of Prochilodontidae and reinforce the hypothesis that small structural chromosome rearrangements were the main cause of the karyotypic diversification seen in this group. Os peixes da família Prochilodontidae são considerados um dos componentes mais importantes da pesca comercial e de subsistência em ambientes de água doce na América do Sul. Essa família compreende 21 espécies e três gêneros. No presente estudo foram analisados os cariótipos de Prochilodus mariae, Semaprochilodus kneri e S. laticeps provenientes de Caicara del Orinoco, Estado Bolivar, Venezuela. As espécies P. mariae, S. kneri e S. laticeps apresentaram 2n=54 cromossomos (40 metacêntricos e 14 submetacêntricos), um único par de cromossomos com regiões organizadoras de nucléolo e uma grande quantidade de heterocromatina em posição centromérica e pericentromérica de quase todos os cromossomos.
