“…Given their patterns of high allopatric diversity (Solem, 1984;Tattersfield, 1996), and the persistence of shells that facilitate relatively easy sampling and species identification (Emberton et al, 1999), land snails are a suitable taxon to address the abovementioned questions. Here, we use land snail data from 16 different karsts in Malaysia to identify correlates of endemism from a set of factors (i.e., karst area, isolation, surrounding soil type and geological age) hypothesized to affect species endemism using generalized linear mixed-effect models.…”

“…In particular, we contrast the levels of diversity and abundance and the composition of the land snail faunas in lowland and montane forest types in several African countries. We also refer to other research that has been undertaken recently elsewhere in Africa, especially in Cameroon (de Winter and Gittenberger, 1998) and Madagascar (Emberton, 1995a, b;Emberton et al, 1999).…”

We report on studies in Tanzania, Kenya, Uganda and South Africa over the past 22 years that have yielded estimates of land-snail diversity in the main forest types occurring in East and eastern southern Africa. When supplemented with the results of similar research in Madagascar and West Africa by other workers, the information provides a more detailed picture of the patterns of land-snail diversity on the continent than was available to Solem (1984). We describe our field methods, reexamine Solem's (1984) assessments of sympatric, allopatric and mosaic diversity patterns in African forests and provide a review of overall species number at continental, regional and country-wide scales, and in the main African forest biomes that have been studied.

“…Esses dados apontam a importância da manutenção da integridade da Mata Atlântica para a preservação das comunidades nativas de invertebrados de serapilheira. Trabalhos recentes vêm demonstrando a importância dos gastrópodes de serapilheira como componentes da biodiversidade e como integrantes da teia alimentar de florestas tropicais (Emberton et al 1999, Hylander et al 2005. Alves et al (1999) relataram a presença de moluscos no conteúdo estomacal da ave Baryphtengus ruficapillus (Vieillot, 1818); Nunes & Santos (2004) Megalobulimus oblongus (Müller, 1774), o aruá-do-mato, espécie rara na Ilha Grande, como já observado por Maciel et al (1984), está incluída na Lista de Animais Ameaçados de Extinção do Estado do Rio de Janeiro (Otero et al 2000).…”

RESUMOA Ilha Grande, situada ao sul do Estado do Rio de Janeiro, possui importantes remanescentes de Floresta Atlântica. Entretanto, o conhecimento sobre sua fauna de invertebrados não-marinhos ainda é restrito, tanto em abrangência de grupos taxonômicos como em áreas geográficas. Devido à importância de inventários de biodiversidade para a conservação e tendo em vista a falta de informação organizada sobre os registros disponíveis, elaboramos uma lista dos táxons citados e suas respectivas localidades, utilizando dados primários de projetos em andamento e as fontes bibliográficas disponíveis. O resultado consiste em uma lista com 465 táxons de invertebrados não-marinhos, a grande maioria do Filo Arthropoda (72,9%) seguido do filo Mollusca (22,15%). Dos táxons citados 27,2% estão na categoria específica e 60% na categoria gênero. A análise dos dados mostrou que houve um incremento de informação a partir de 1999, e que essa informação está concentrada no entorno da Vila Dois Rios. Os resultados apresentados demonstram a necessidade de realização de inventários de fauna, com ampliação dos grupos taxonômicos e das áreas estudadas, no sentido de completar as imensas lacunas detectadas. Palavras-chave: Banco de dados; diversidade; Floresta Atlântica; lista faunística; Rio de Janeiro. ABSTRACT CURRENT KNOWLEDGE OF THE NON-MARINE INVERTEBRATES FAUNA OF ILHA GRANDE (ANGRA DOS REIS, RJ). Ilha Grande, a continental island located at Southern of Rio deJaneiro state, has important remnants of Atlantic Rainforest. However, the knowledge of the non-marine invertebrate fauna is not sufficiently well known, concerning not only taxonomic groups but also geographic areas. Considering the relevance of biodiversity inventories to conservation, allied to the absence of organized information about the existing data, we prepared a taxonomic list of the non-marine invertebrates reported to Ilha Grande, including distributional data, based on primary data of ongoing research projects and literature. The list is composed of 465 taxa of non-marine invertebrates, mainly Arthropoda (72.9%), followed by Mollusca (22.15%). Among cited taxa 25.52% are in the species category and 60% are in the genus category. The data analysis revealed an information increase since 1999 and that this information are concentrated at Vila Dois Rios region. Results show the need for improving Ilha Grande faunistic inventories, focusing taxonomic groups and areas, in order to fill the huge existing gaps.
