TLDR
For Jeriquara, the diversity of mites on surface of leaves, as well as in domatia, and on branches and fruits was higher than for Garca, and Brevipalpus phoenicis and Oligonychus ilicis were the most abundant and frequent phytophagous mite species.Abstract:
O presente estudo teve como objetivo caracterizar a diversidade de acaros em cafeeiros da cultivar Mundo Novo em duas importantes regioes produtoras (Jeriquara e Garca) do Estado de Sao Paulo. Para tanto, foram coletadas amostras quinzenais de folhas, ramos e frutos, entre abril de 2001 e junho de 2003, do terco medio de 10 plantas tomadas ao acaso em cada campo. De cada planta foram tomadas 12 folhas (cada uma do terceiro ou quarto par a partir da extremidade distal de um ramo), 12 ramos (25 cm apicais) e 100 frutos. Foram coletados no total 13.052 acaros nos dois locais estudados, sendo 7.155 em Jeriquara e 5.897 em Garca. De um total de 108 especies de acaros coletados de plantas de cafe neste estudo, 45 especies foram observadas em ambos os locais estudados, que apresentaram similaridade de 56%. O numero de especies encontradas exclusivamente em Jeriquara (47) foi aproximadamente tres vezes superior ao numero de especies observadas somente em Garca (16). Em Jeriquara, a diversidade foi maior tanto na superficie das folhas, quanto nas domacias, ramos e frutos. Nos dois locais estudados, Brevipalpus phoenicis (Geijskes, 1939) e Oligonychus ilicis (McGregor 1919) foram as especies de fitofagos mais abundantes e frequentes. Os estigmeideos e fitoseideos foram os acaros predadores mais abundantes e frequentes em ambos locais. As especies mais abundantes e frequentes de predadores foram Agistemus brasiliensis Matioli, Ueckermann & Oliveira, 2002, Zetzellia malvinae Matioli, Ueckermann & Oliveira, 2002, Euseius citrifolius Denmark & Muma, 1970 e Euseius concordis (Chant 1959) em Jeriquara; e Z. malvinae, E. citrifolius e E. concordis em Garca.read more

TL;DR: The results suggest a highly complex mosaic of phylogeographical patterns in South America, which is suggestive of high levels of undocumented species diversity.

Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy
TL;DR: Taxonomic implications of the proposed classification and the position of the incertae sedis genera within Characidae are discussed, and a discussion of the phylogenetic information of the characters used in the classical systematics of theCharacidae is provided.

TL;DR: This paper presents a subdivision of Brazil into phytogeographic domains, and cites studies that have explored the detection of biogeographic units (areas of endemism) and how they are historically related among those domains.

Modeling landscape dynamics in an Atlantic Rainforest region: Implications for conservation
Ana Maria G. Teixeira,Britaldo Soares-Filho,Simone R. Freitas,Simone R. Freitas,Jean Paul Metzger +4 more
TL;DR: In this article, the authors investigated changes in an Atlantic Rainforest region due to major biophysical and human proximate causes, including land cover and land-use changes from 1962 to 2000, including deforestation and forest regrowth, and thereby simulated future landscape trajectories to assess their possible effects on the conservation of forest species of the Ibiuna Plateau.

Plants, mites and mutualism: leaf domatia and the abundance and reproduction of mites on Viburnum tinus (Caprifoliaceae).
TL;DR: By directly aiding and abetting the third trophic level, plants with leaf domatia may increase the efficiency of some predaceous and microbivorous mites in consuming plant enemies.
Journal ArticleDOI
Occurrence of predatory and fungivorous mites in leaf domatia
TL;DR: It is hypothesized that leaf domatia serve as shelters and nurseries for mites which in turn eat phytophagous arthropods and pathogens using the plants, which could be of importance to agriculture since domatias are known to occur in some crop plants, including coffee, grape, and walnut.

Biotic interactions of mites, plants and leaf domatia.
TL;DR: By providing refuges for herbivores, however, domatia may stabilize interactions between predator and their mite prey and thereby reduce the chances of herbivore outbreaks.
