| The reproductive system of male Phrynops geoffroanus adults is macroscopically described and the variation in testicular biometry is evaluated. A pair of oval testes is connected by the efferent ductules to the epididymis, which continue as deferent ducts, which emerge in the penis. The volume of the gonads showed the highest averages during spring and summer months. GSI varied significantly throughout the year, with the highest averages observed in the months that correspond to the end of spring and the beginning of summer, when the reproduction of the species takes place, and the lowest averages were seen in winter, suggesting a cyclical testicular activity. |

| O presente trabalho teve por objetivo estudar a biologia e distribuição de Imparfinis minutus na microbacia do Ribeirão Grande (22º47´08´´S, 45º28´17´´W), serra da Mantiqueira oriental, nos períodos de julho e outubro de 2001 e janeiro e abril de 2002. Dentre as 37 espécies amostradas, I. minutus (Siluriformes, Heptapteridae) distribuiu-se desde o pediplano, até a planície do Vale do Paraíba, e esteve associada a ambientes pouco profundos, com substrato constituído principalmente por pedra, cascalho e matacão. O comprimento total dos indivíduos na população variou de 4,75 a 12,75 cm. A curva ajustada da relação peso-comprimento para a população foi p = 0,0052 C3,13. Os fatores de condição alométrico (Ka) e relativo (Kr) apresentaram tendências semelhantes,... |

| Insects are important environmental bioindicators, due to the species diversity and wide range of habitats occupied. The present study evaluated the temporal variation in composition and abundance of soil insects in an urban forest fragment in the municipality of Toledo, in the state of Paraná, by analyzing their abundance and seasonality. Monthly samplings were conducted between August 2011 and July 2012 at four sampling sites within the fragment. At each site, three pitfall traps remained exposed for 48 hours. Captured insects were fixed in alcohol, sorted and identified. Throughout the study period, we captured 11,568 insects from 11 orders and 35 families. Coleoptera was the richest order (12 families), followed by Diptera and Hemiptera (5),... |

| Inventories are the basis of every work with biodiversity, with increased importance due to the current environmental crisis. Bats are one of the most diverse groups of mammals, with high ecologic versatility and are good bioindicators to monitor environmental impacts. We performed a two-stage survey at an Atlantic Forest reserve in the State of Paraíba, the first stage registering 187 individuals of 24 species and the second stage, 1073 individuals of 11 species; the second stage’s richness being a subset of the first as pointed by the Mann-Whitney test. The second stage was more efficient in accumulating individuals, while the first accumulated species more efficiently. The diversity estimation (Chao 1) pointed that the survey was efficient in... |
