Letícia Soares (MSc INPA 2011) 

Letícia is an evolutionary biologist with interests in ornithology, parasitology, biogeography and molecular biology. Her research centers on host-parasite evolution and interactions, with a focus on host-parasite systems, such as malaria and Chagas disease, where a group of phylogenetically related pathogens can infect both human and animal hosts in the wild.  Letícia completed her MSc. in Ecology at INPA in 2010, advised by Drs. Ferraz and Fernando Abad-Franc (FIOCRUZ-AM). Her master's thesis investigated sex-biased incidence of cutaneous leishmaniasis in human populations. She is now a 6th-year PhD candidate in the Ricklefs lab, at the University of Missouri Saint Louis. Letícia co-manages a science outreach blog, The Naked Darwin.


Ulisses Camargo (MSc INPA 2011) 

Ulisses' interests center on population modeling and numerical ecology; he is currently a PhD candidate at the University of Helsinki, working at the Metapopulation Research Centre. His doctoral work combines autonomous recording of bird vocalizations, automated identification of the recorded signals, and hierarchical Bayesian methods for analyzing the identification results. By integrating these resources, Ulisses is developing a novel, multidisciplinary approach to study the dynamics of tropical bird communities. Ulisses is a Biologist trained at the University of São Paulo in Ribeirão Preto and joined the lab as an MSc. student at INPA, in 2009. He headed the lab's autonomous recording crew for five consecutive years.  Ulisses’ CV & Email

Aída Rodrigues (MSc INPA 2010)

A biologist trained at Universidade Federal do Amazonas, Aída is interested in natural history, evolution of visual signals, and the influence of behavior on population dynamics.  She joined the lab as a INPA MSc student in 2010, where she found that army ant-following birds have equally high site-fidelity in secondary and old-growth forests, even though these birds rely on a resource that appears to be less predictable in secondary forests. Aída is currently a PhD student at Endler’s Lab (Deakin University, Australia) where she studies acoustic and visual signals in courtship displays of the Great Bowerbird. Her current obsessions include bowerwatching, stone collecting (too much hanging out with bowerbirds!), and swing dancing with her mates. Aída's CV & Email

Murilo Guimarães (PhD UNICAMP 2013) 

Murilo has a B.A. in biology from Universidade Católica de Santos and a Master’s in Animal Biology from Universidade Estadual Paulista. During his PhD at the Ecology Department of UNICAMP, he used mark-recapture models to estimate amphibian and reptile population parameters. He is currently a Postdoctoral fellow at INPA under the supervision of Drs. Jansen Zuanon and Gonçalo Ferraz. Murilo’s current work is divided between modeling survival and movement of stream fish in experimental field settings, and mapping spatial distribution of nocturnal birds. His main interests are quantitative population ecology, field sampling techniques, and swimming. Murilo’s CV & Email


gone but not forgotten

Bento Collares Gonçalves (BA UFRGS 2014)

Bento is a UFRGS-trained biologist who joined the lab as an undergraduate in 2013. His work was an attempt to gauge the extent of false positive errors on bioacoustic sampling of Central Amazon birds. To do this, Bento used an online quiz supplied with bird vocalization recordings. For simplicity, his study was taxonomically restricted to antbirds and woodcreepers – including some of the most common and well known birds in the study area. Not surprisingly, Bento's results showed that false positive errors are pervasive in our study setting; he even drew a dendrogram of his study group, based solely on identification errors. Bento is now a PhD student in the Department of Ecology and Evolution at Stony Brook University, New York. Bento's CV and Email.


Thiago B. D'Araújo Couto (MSc INPA 2013)

Thiago got his undergraduate training in Biology at the Universidade de Brasília and joined the lab in 2011 as an INPA Ecology MSc. student co-advised by Gonçalo and Jansen Zuanon. Thiago is currently a PhD student advised by Dr. Julian Olden at the University of Washington, Seattle. Thiago's research interests center on aquatic ecology, and the effects of landscape disturbance on the spatial distribution and natural history of stream fishes. Thiago's MSc project employed a multi-species occupancy model to examine whether some stream fish are restricted to the most temporary of the upstream environments .Thiago's websiteEmail.


Marconi Campos Cerqueira, Jr. (MSc INPA 2009)

Best bird ear in the lab for a long time, Marconi got his undergraduate Biology degree at the Universidade Federal de Ouro Preto in the state of Minas Gerais. His MSc project about rarity of primary forest birds pioneered the use of a spaced-repetition learning software to help observers memorize bird sounds. He found that most expert predictions about who is rare and who is common were qualitatively right and produced estimates of site occupancy that provide a solid basis for assessing rarity. Marconi is now a PhD candidate at the University of Puerto Rico – Rio Piedras, supervised by Dr. Mitchell Aide . Marconi's CV & Email
