The foraging behavior of the Large-headed Flatbill, Ramphotrigon megacephalum and the Dusky-tailed Flatbill, Ramphotrigon fuscicauda (Aves: Tyrannidae) Rev. Bras. Zool.
Melo,Tomaz Nascimento de; Guilherme,Edson.
ABSTRACT Southwestern Amazonia has great bird diversity which includes birds specialized in bamboo forests. In this region, bamboo is considered a key element of the landscape. The objective of this study was to investigate and describe the foraging behavior of the Large-headed Flatbill, Ramphotrigon megacephalum (Swainson, 1835) and the Dusky-tailed Flatbill, Ramphotrigon fuscicauda Chapman, 1925, which occur sympatrically in the region and are considered bamboo specialists. This study was conducted between November 2013 and September 2014, within two fragments in the eastern portion of the state of Acre: Fazenda Experimental Catuaba, in the municipality of Senador Guiomard; and Reserva Florestal Humaitá, in Porto Acre. A total of 109 and 97 foraging...

Diagnosis, presence of endoparasites, and local knowledge on the infestation of the exotic giant African snail (gastropoda: pulmonata: achatinidae), in the urban zone of Rio Branco, Acre, Brazil Biota Neotropica
Lima,Marcos Silva de; Guilherme,Edson.
Abstract The giant African land snail, Lissachatina fulica is considered to be one of the world's worst invader species. This snail can provoke major economic and public health problems in urban areas, in particular as a potential vector of nematodes that infect both humans and animals. In this context, the present study investigated the extent of the infestation of this exotic snail in the urban neighborhoods of the city of Rio Branco, verified the presence of endoparasites in these snails, and evaluated the knowledge of local residents with regard to the presence of this invader species. For this, daytime surveys were conducted between August 2015 and June 2016. For the analysis of endoparasites, 44 live specimens were sent to the National Reference...

Occurrence of endo and hemoparasites in Sporophila caerulescens captured in the eastern region of the state of Acre, Brazil Ciência Rural
Souza,Leandro Siqueira de; Guilherme,Edson; Andrade,Angela Maria Fortes de; Santos,Francisco Glauco de Araújo.
ABSTRACT: Wild animals are hosts and reservoirs to many infectious agents, often unknown to the Scientific Community, which leads to serious health implications for natural and domestic environments. We conducted this research with the objective of diagnosing the occurrence of parasites of medical and veterinary interest in “coleirinhos” captured in the eastern region of the state of Acre, Brazil. We captured the specimens in August and September of 2017 using ornithological nets at the margins of Caeté river. We visually inspected the birds to evaluate the ectoparasites. Subsequently, we collected blood through a brachial vein puncture and rested the individuals in a cloth bag for 30 minutes to collect feces, after which we released them. Results of the...
