A phylogenetic study of the subtribe Dicrepidiina (Elateridae, Elaterinae, Ampedini)

It is presented a cladistic analysis of the Dicrepidiina aiming to test the monophyletism of the subtribe and to establish the relationships among the genera. The subtribe is composed by 36 genera and all of them, except Asebis, Lamononia, Neopsephus, Semiotopsis and Spilomorphus were included in the analysis. Fifty two species, especially the type-species of each genus were studied: Achrestus flavocinctus (Cand��ze, 1859), A. venustus Champion, 1895, Adiaphorus gracilis Schwarz, 1901, A. ponticerianus Cand��ze, 1859, Anoplischiopsis bivittatus Champion, 1895, Anoplischius bicarinatus Cand��ze, 1859, A. conicus Cand��ze, 1900, A. haematopus Cand��ze, 1859, A. pyronotus Cand��ze, 1859, Atractosomus flavescens (Germar, 1839), Blauta cribraria (Germar, 1844), Calopsephus apicalis (Schwarz, 1903), Catalamprus angustus (Fleutiaux, 1902), Crepidius flabellifer (Erichson, 1847), C. resectus Cand��ze, 1859, Cyathodera auripilosus Costa, 1968, C. lanugicollis (Cand��ze, 1859), C. longicornis Blanchard, 1843, Dayakus angularis Cand��ze, 1893, Dicrepidius ramicornis (Palisot de Beauvois, 1805), Dipropus brasilianus (Germar, 1824), D. factuellus Cand��ze, 1859, D. laticollis (Eschscholtz, 1829), D. pinguis (Cand��ze, 1859), D. schwarzi (Becker, 1961), Elius birmanicus Cand��ze, 1893, E. dilatatus Cand��ze, 1878, Heterocrepidius gilvellus Cand��ze, 1859, H. ventralis Gu��rin-M��neville, 1838, Lampropsephus cyaneus (Cand��ze, 1878), Loboederus appendiculatus (Perty, 1830), Olophoeus gibbus Cand��ze, 1859, Ovipalpus pubescens Solier, 1851, Pantolamprus ligneus Cand��ze, 1896, P. mirabilis Cand��ze, 1896, P. perpulcher Westwood, 1842, Paraloboderus glaber Golbach, 1990, Proloboderus crassipes Fleutiaux, 1912, Propsephus beniensis (Cand��ze, 1859), P. cavifrons (Erichson, 1843), Pseudolophoeus guineensis (Cand��ze, 1881), Rhinopsephus apicalis (Schwarz, 1903), Sephilus formosanus Schwarz, 1912, S. frontalis Cand��ze, 1878, Singhalenus gibbus Cand��ze, 1892, S. taprobanicus Cand��ze, 1859, Sphenomerus antennalis Cand��ze, 1859, S. brunneus Cand��ze, 1865, Spilus atractomorphus Cand��ze, 1859, S. nitidus Cand��ze, 1859, Stenocrepidius simonii Fleutiaux, 1891 and Trielasmus varians Blanchard, 1846. Chalcolepidius zonatus (Hemirhipini, Agrypninae), Ctenicera silvatica (Prosternini, Prosterninae), and species of the other subtribes of Ampedini (Elaterinae): Ampedus sanguineus (Ampedina), Melanotus spernendus (Melanotina) and Anchastus digittatus and Physorhinus xanthocephalus (Physorhinina) were used as outgroups. The results of the phylogenetic analysis demonstrated that Dicrepidiina, as formerly defined, does not form a monophyletic group. One genus, represented by Ovipalpus pubescens, was removed from the subtribe. The subtribe is characterized by presence of lamella under 2nd and 3rd tarsomeres of all legs. Also, it was revealed that the genera Achrestus, Anoplischius, Dipropus and Propsephus are not monophyletic. Due to the scarcity of information, all the studied species are redescribed and illustrated.

An��lise colorim��trica e espectrosc��pica do muco de carac��is terrestres Achatina sp alimentados com ra����o diferenciada

Foram estudados os efeitos da adi����o de plantas medicinais de princ��pios cicatrizantes (Centelha asi��tica, Papa��na e Confrei) na ra����o controle de carac��is terrestres, para se avaliar a interfer��ncia destas plantas na composi����o do muco glicoprot��ico. Foram utilizados 80 carac��is terrestres Achatina sp, baseados em um peso homog��neo (49 e 40 g e idade m��dia de 10 e 19 meses para Achatina fulica e Achatina monochromatica, respectivamente). Os animais foram distribu��dos aleatoriamente em oito grupos experimentais: controle Achatina fulica (FC) e Achatina monochromatica (MC), centelha asi��tica Achatina fulica (FCe) e Achatina monochromatica (MCe), papa��na Achatina fulica (FPa) e Achatina monochromatica (MPa) e confrei Achatina fulica (FCo) e Achatina monochromatica (MCo). ��gua e ra����o foram fornecidos ad libitum. Ao final de 150 dias de tratamento, os animais foram submetidos �� t��cnica de extra����o do muco glicoprot��ico, por meio do est��mulo manual da gl��ndula podal, respons��vel pela secre����o deste muco. Esta metodologia considerou o bem-estar dos animais, uma vez que os mesmos n��o foram sacrificados e retornaram ao seu sistema de cria����o. Os mucos foram analisados por meio de testes colorim��tricos e espectrosc��picos, que constataram altera����es semelhantes, por��m apresentaram varia����o significativa em sua composi����o glicoprot��ica.

Patterns of distribution of the hermit crab Loxopagurus loxochelis (Moreira, 1901) (Decapoda, Diogenidae) in two coastal areas of southern Brazil

The present study determined the distribution pattern of the hermit crab Loxopagurus loxochelis by a comparison of catch, depth and environmental factors at two separate bays (Caraguatatuba and Ubatuba) of Sao Paulo State, Brazil. The influence of these parameters on the distribution of males, non- ovigerous females and ovigerous females was also evaluated. Crabs were collected monthly, over a period of one year (from July/2002 to June/2003), in seven depths, from 5 to 35 m. Abiotic factors were monitored as follows: superficial and bottom salinity (psu), superficial and bottom temperature (C), organic matter content (%) and sediment composition (%). In total, 366 hermit crabs were sampled in Caraguatatuba and 126 in Ubatuba. The highest frequency of occurrence was verified at 20 m during winter (July) in Caraguatatuba and 25 m during summer (January) in Ubatuba. The highest occurrences were recorded in the regions with bottom salinities ranging from 34 to 36 psu, bottom temperatures from 18 to 24 C and, low percentages of organic matter, gravel and mud; and large proportion of sand in the substrate. There was no significant correlation between the total frequency of organisms and the environmental factors analyzed in both regions. This evidence suggests that other variables as biotic interactions can influence the pattern of distribution of L. loxochelis in the analyzed region, which is considered the limit of the northern distribution of this species.

The Cramer-Rao bound for initial conditions estimation of chaotic orbits

We derive the Cramer-Rao Lower Bound (CRLB) for the estimation of initial conditions of noise-embedded orbits produced by general one-dimensional maps. We relate this bound`s asymptotic behavior to the attractor`s Lyapunov number and show numerical examples. These results pave the way for more suitable choices for the chaotic signal generator in some chaotic digital communication systems. (c) 2006 Published by Elsevier Ltd.
