Balanço hídrico de Guarea trichilioides L., na estação seca, em São José do Rio Preto

Guarea trichilioides L.4, (= Guarea guara (N.J. Jacquin) P. Wilson) é uma meliácea arbórea silvestre, fornecedora de madeira vermelha e conhecida, na região de São José do Rio Preto, pelo nome de "Marinheiro". Foi estudado o balanço hídrico desta planta na estação seca, pelo método das pesagens rápidas de folíolos destacados, verificando-se que, nas condições consideradas, não houve, praticamente, restrição acentuada da transpiração nas horas mais desfavoráveis do dia. A transpiração relativa foi bastante elevada, comparável aquela de outras árvores da mesma formação e bem superior à das árvores da floresta pluvial tropical. A transpiração cuticular foi baixa, comparável à da maioria das árvores da citada floresta pluvial e bem inferior àquela de muitas plantas permanentes do cerrado. O movimento hidroativo dos estômatos foi relativamente rápido na fase inicial, tornando-se, porem, bastante vagaroso antes de atingir o valor da transpiração cuticular. O deficit de saturação foi pequeno, comparável ao das árvores da floresta pluvial. O estudo do balanço hídrico e da estrutura foliar levam a considerar Guarea trichilioides como uma árvore da floresta tropical não adaptada a suportar condições de seca intensa.

Age and growth parameters of cachara Pseudoplastystoma reticulatum (Siluriformes, Pimelodidae) from the Cuiabá River, Brazil

Age and growth parameters of cachara Pseudoplatystoma reticulatum (Eigenmann & Eigenmann, 1889) (Siluriformes, Pimelodidae) (males and females) were estimated through the analysis of growth rings in spines of pectoral fins. Fish were collected from January to December 2007, in the area directly influenced by the Aproveitamento Múltiplo de Manso (APM Manso) and in the Cuiabá River (upper parts of the Pantanal). The maximum number of growth rings was seven for males, and eight, for females. The analysis of temporal variations in mean marginal increment showed that rings found in the spines were formed annually, in December. Growth rings were associated to spawning (in the study region from November to March) of the species. The growth curve in length was obtained by the von Bertalanffy model adjusted by the Ford-Walford transformation. The equations are: Ls = 72.7*[1-e-0.44(t+1.5974)] for males, and Ls = 84.5*[1-e-0.33(t+2.0943)] for females. The equations that describe the growth curve in weight are: Wt = 4991.61*[1-e-0.44 (t+1.5974] 2.70 for males and Wt = 7503.17*[1-e-0.33 (t+2.0943] 2.99 for females.

Comparative morphology of the type-species of Isotes and Synbrotica(Coleoptera, Chrysomelidae, Galerucinae), with a new synonymy of species

ABSTRACT In order to solve the affinities of the species of Isotes Weise, 1922, a detailed morphological comparative study was carried out based on type-species of Isotes and its junior synonym,Synbrotica Bechyné, 1956. Isotes tetraspilota (Baly, 1865) and Isotes borrei (Baly, 1889) had their morphology of mouthparts, endosternites, wings and both male and female genitalia compared by the first time. A new synonymy is established between Isotes borrei (Baly, 1889) and Isotes crucigera (Weise, 1916) syn. nov. based on external and genitalia morphology. New structures for Section Diabroticites Chapuis, 1875 are presented and discussed.
