Caracterização e gênese de solonetz solodizado do sertão central e do médio Jaguaribe - estado do Ceará

Foram estudados três perfis de solos localizados na região semi-árida do estado do Ceará, classificados como Solonetz Solodizado (Typic Natrustalf). São solos relativamente rasos, de variação textural abrupta. Os horizontes superficiais são constituídos por material arenoso, retrabalhado, sobre horizonte nátrico mais argiloso. Mineralogicamente, são solos pouco desenvolvidos, dominados por argilas 2:1 (micas, vermiculita e montmorilonita), ocorrendo ainda um pouco de caulinita e plagioclásios. Nas frações mais grosseiras ocorrem, além do quartzo, minerais intemperizáveis, como plagioclásios, calcita, micas, hornblenda, entre outros.

Dieta e comportamento de forrageamento de Suiriri affinis e S. islerorum (Aves, Tyrannidae) em um cerrado do Brasil central

Foi estudado o comportamento de forrageamento de Suiriri affinis (suiriri-do-cerrado) e S. islerorum (suiriri-da-chapada), duas espécies de Tyrannidae que ocorrem em sintopia nos cerrados do Brasil central. Durante o ano de 2003 foram registradas 188 observações de forrageamento para S. affinis e 150 para S. islerorum. Foram encontradas diferenças significativas entre as duas espécies em relação à altura e substrato de forrageamento, fitofisionomia utilizada e densidade da folhagem no local do ataque. O comportamento e a direção do ataque, a espécie de planta e a distância de vôo não diferiram entre as espécies. A análise de 26 conteúdos estomacais de membros do gênero revelou o consumo exclusivo de artrópodes. A baixa porcentagem de observações de forrageamento direcionadas a frutos (apenas 7% e 9%, respectivamente) confirmou o caráter insetívoro do gênero.

Breeding activity of Scinax centralis (Anura, Hylidae) in Central Brazil

From January, 1997 to April, 1998, we studied breeding activity in a population of Scinax centralis Pombal & Bastos, 1996, in the state of Goiás, inside the Cerrado Biome, Brazil. The behavior of males and females in the choruses, the relationships between environmental variables and the presence of individuals, the spatial distribution pattern, amplexus and clutches were analyzed. The breeding season occurred from November to May. The majority of males began to call when they entered the chorus; they were defending their calling sites against other males. We found a positive correlation between the number of females and males in the choruses, but no significant correlation was observed between the operational sexual ratio (OSR, number of reproducing females/number of reproducing males) and the number of calling males. OSR was highly male-biased; on average, there were 40 males for each female. The presence of individuals was positively correlated with air temperature of two previous days and negatively correlated with rainfall on the observation day. Generally, males were non-randomly distributed and satellite males were observed. Females were larger and heavier than males. Egg number, but not diameter of the egg, was correlated with the female size.
