Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...

Physical disturbance of plants or plant parts results in a mechanical stress response from the plant. Mechanical stress applied naturally or under controlled conditions inhibits growth in mass and dimensions of major plant parts. Wind and precipitation are important natural sources of mechanical stress. Under field conditions, cultivated plants experience these natural mechanical stresses plus ...

Mitchell et al. present a lucid and provocative challenge to the claim that links between mental representations are formed automatically. However, the propositional approach they offer requires clearer specification, especially with regard to how propositions and memories interact. A definition of a system would also clarify the debate, as might an alternative technique for assessing task

Much research effort in the GA community has been directed at identifying what, if anything, GA’s are good for ([Forrest & Mitchell, 1993], [Goldberg, 1994], [Mitchell et al., 1995]). The building-block hypothesis ([Holland, 1975], [Goldberg, 1989]) directs our attention to problems which exhibit a decomposable structure, and the Royal-Road problems [Mitchell et al. 1992] were a first attempt a...

Three new species of the spider genus Philoponella Mello-Leitão, 1917 are described: Philoponella opelli n. sp. from Brazil and Ecuador, and Philoponella fluviidulcifis n. sp. , and Philoponella duopunctata n. sp. from Brazil. New records for Philoponella vittata (Keyserling, 1881), P. republicana (Simon, 1891), P. fasciata (Mello-Leitão, 1917) and P. divisa Opell, 1979 are provided for Brazil ...

Bovine mastitis is very common in cows of both developed and developing countries. The prevalence of clinical and subclinical mastitis (SCM) varies from region to region. Hence, the present study was carried out to determine the prevalence of mastitis using three diagnostic tests by considering different risk factors like age, lactation, breed, season, quarters, and herd. The results showed tha...

BACKGROUND Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history and diversification through time are largely unknown. METHODOLOGY AND RESULTS We employed sequences of two chloroplast regions (trnL-trnF, rbcL) and the nuclear ribosomal ITS region of 3...
