1. Reproductive phenology of the American Bullfrog in subtropical Brazil: photoperiod as a main determinant of seasonal activity
RESUMO A rã-touro americana continua invadindo ecossistemas em todo o mundo, causando declínios e extinções nas populações. Em sua distribuição nativa, a espécie apresenta estação reprodutiva prolongada e grande fertilidade. Contudo, dados sobre a fenologia reprodutiva da espécie ex-situ em localidades invadidas provêm principalmente de relatos

2. A hipóxia é um estressor para girinos de rã-touro?
Avaliou-se o cortisol em girinos de rã-touro (Lithobates catesbeianus), no estágio de pró-metamorfose ao mecanismo estressor de hipóxia juntamente com captura (1º experimento) e adensamento (2º experimento). O experimento de captura foi composto pelos tratamentos: Captura individual com puçá, Captura em massa com puçá e Captura por escoamento, com

3. Diet and trophic niche of Lithobates catesbeianus (Amphibia: Anura)
Lithobates catesbeianus (Shaw, 1802) is an invasive anuran introduced in Brazil that is associated with the displacement and the decline of populations of native species worldwide. There is evidence that biological invasions are facilitated by certain attributes of the invading species, for instance niche breath, and that invasive species have a broader ecol

4. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

6. Occurrence of heavy metals and antibiotic resistance in bacteria from internal organs of american bullfrog (Rana catesbeiana) raised in Malaysia
A total of 40 bacteria have been successfully isolated from internal organs of the American bullfrog (Rana catesbeiana) raised in Malaysia, namely, eight isolates of Aeromonas spp., 21 of Edwardsiella spp., six of Flavobacterium spp. and five of Vibrio spp. In terms of antibiotic susceptibility testing, each isolate was tested against 21 antibiotics, resulti

7. Molecular cloning of bullfrog saxiphilin: a unique relative of the transferrin family that binds saxitoxin.
Plasma and tissue of certain vertebrates contain a protein called saxiphilin that specifically binds the neurotoxin saxitoxin with nanomolar affinity. We describe the isolation of a cDNA clone of saxiphilin from liver of the North American bullfrog (Rana catesbeiana). The cDNA sequence encodes a protein that is evolutionarily related to members of the transf

8. Erythrocyte differentiation during the metamorphic hemoglobin switch of Rana catesbeiana.
Anurans (frogs and toads) switch from tadpole to adult hemoglobin synthesis during metamorphosis. A number of workers have attempted to determine whether tadpole and adult Hb types are expressed in the same or different erythroid cells during the switch. If the different Hb types are found in different cells during the transition, the switch in globin gene e

9. Sequence variation in transcription factor IIIA.
Previous studies characterized macromolecular differences between Xenopus and Rana transcription factor IIIA (TFIIIA) (Gaskins et al., 1989, Nucl. Acids Res. 17, 781-794). In the present study, cDNAs for TFIIIA from Xenopus borealis and Rana catesbeiana (American bullfrog) were cloned and sequenced in order to gain molecular insight into the structure, funct
