Under the light: high prevalence of haemoparasites in lizards (Reptilia: Squama...
PICELLI,AMANDA M.; RAMIRES,ADRIANE C.; MASSELI,GABRIEL S.; PESSOA,FELIPE A.C.; VIANA,LUCIO A.; KAEFER,IGOR L.Abstract Blood samples from 330 lizards of 19 species were collected to investigate the occurrence of haemoparasites. Samplings were performed in areas of upland (terra-firme) forest adjacent to Manaus municipality, Amazonas, Brazil. Blood parasites were detected in 220 (66%) lizards of 12 species and comprised four major groups: Apicomplexa (including haemogregarines, piroplasms, and haemosporidians), trypanos...
Composition and ecology of a snake assemblage in an upland forest from Central ...
MASSELI,GABRIEL S.; BRUCE,ALLAN D.; SANTOS,JUCIMARA G. DOS; VINCEN,TIMOTHY.; KAEFER,IGOR L.Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Experimental Farm area of the Federal University of Amazo...
The peculiar breeding biology of the Amazonian frog Allobates subfolionidifican...
SOUZA,JESUS R.D.; KAEFER,IGOR L.; LIMA,ALBERTINA P.ABSTRACT Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductive behavior. The space use of A. subfolionidificans individuals differed between sexes, with males using small...
Reproductive phenology of the American Bullfrog in subtropical Brazil: photoper...
MEDEIROS,CAMILA I.; BOTH,CAMILA; KAEFER,IGOR L.; CECHIN,SONIA Z.ABSTRACT The North American bullfrog Lithobates catesbeianus continues to invade ecosystems worldwide, potentially causing population declines and even extinctions. Within its native distribution, bullfrogs show prolonged reproductive seasons and high fertility. However, data on breeding biology of bullfrogs ex-situ in invaded localities mainly comes from anecdotal reports. Understanding how invasive species ar...
