“…Each individual observation lasted for approximately 15 seconds and included the type of activity (feeding, resting, agonistic display, sexual display, attacking or fleeing), sex, age (juveniles or adults), estimated size of the individuals (when involved in intra-or interespecific interactions), and its color pattern. Quantitative data about behavioral categories and interactions were gathered by a single observer (RRR) that stayed motionless at a distance from the subjects in order to avoid disturbing the fish (Sabino, 1999). Color patterns were characterized following Baerends & Baerends van-Roon (1950) and Römer (2001), describing general body color and emphasizing the presence of dark bands, stripes, and blotches in the head and body of the individuals (Fig.…”

Color changing and behavioral context in the Amazonian Dwarf Cichlid Apistogramma hippolytae (Perciformes)

et al. 2009

Animal coloration has many functions, and fishes are noted among vertebrates for presenting a wide variety of color patterns. Although in marine fishes the relationship between body coloration and behavioral context is well documented, there's not much information about freshwater fishes. Here we describe color patterns displayed by the dwarf cichlid Apistogramma hippolytae and suggest that these patterns are dependent on different social and behavioral settings. Field observations were conducted underwater in a pond in Central Amazonia, Brazil. We recorded six body coloration patterns related to seven different kinds of behavioral activities: foraging, resting, reproductive and agonistic displays, aggression (attacking and fleeing) and parental care. Changes in coloration occur rapidly and take only a few seconds. Females on parental care exhibited a unique pattern that are more persistent and probably manifests more slowly. In the shallow and clear waters of the natural environment of this dwarf cichlid, color communication seems to constitute an efficient way to display information about individual mood, social status and reproductive readiness, contributing to minimize loss of energy in unnecessary interactions.Coloração animal tem diferentes funções, e os peixes se destacam entre os vertebrados por apresentarem uma grande diversidade de padrões de cores. Embora se conheça relativamente bem a relação entre coloração e contexto comportamental para peixes marinhos, pouco se sabe para os peixes de água doce. Nós descrevemos os padrões de coloração de um ciclídeo amazônico, Apistogramma hippolytae, e sugerimos como esses padrões são dependentes das características sociais e comportamentais. Realizamos observações subaquáticas utilizando mergulho livre em campo durante o dia em uma lagoa na Amazônia Central. Nós caracterizamos seis padrões de coloração associados a sete comportamentos diferentes: alimentação, repouso, displays sexual e agonístico, agressão (ataque e fuga) e cuidado parental. As mudanças de coloração levam apenas alguns segundos. Fêmeas em cuidado parental exibem um padrão exclusivo, cuja mudança é mais lenta. No ambiente natural desse ciclídeo, locais rasos com águas claras, a comunicação por coloração pode ser um sistema eficiente de comunicar o estado motivacional individual, status social e disposição para reprodução, possivelmente contribuindo para minimizar a perda de energia com interações desnecessárias.

“…Transparent rivers and streams, like the rio Itatinga of the RPPN Parque das Neblinas, are favorable to underwater studies, especially as a tool to obtain data on feeding strategies, reproduction and relationships with other aquatic organisms (Sabino & Castro 1990, Sabino 1996, Sabino 1999). Mid and long term studies about the fish community in the rio Itatinga are also of great interest, as they may make it possible to analyze the ichthyofauna's response to forest regeneration.…”

Ichthyofauna of the rio Itatinga in the Parque das Neblinas, Bertioga, São Paulo State: composition and biogeography

2007

Little is known about the ichthyofauna from South American coastal plain, specially concerning the Mata Atlântica (Atlantic Forest) rivers and streams, as there are regions little explored which may have nondescribed or rare species. An example is the Parque das Neblinas, a Natural Patrimony Private Reserve (RPPN) in the Bertioga municipality, São Paulo state, where no ichthyofaunal study had been done before. The park's hydrography is made up by the rio Itatinga with its various tributary streams, which flow into the Itapanhaú river basin. Nine sites were sampled using sieves, seines and gill nets; 1,086 specimens of seven species, three orders and five families were captured. The most representative species were Astyanax paranae, Phalloceros caudimaculatus, and Coptobrycon bilineatus. Four of those collected are on the Brazilian list of endangered species: Coptobrycon bilineatus, Glandulocauda melanogenys, Pseudotocinclus tietensis, and Taunaya bifasciata; one, Trichomycterus sp., has an undefined taxonomic status, possibly being a non-described species. The richness of species found in the upper part of the rio Itatinga is typical of the Mata Atlântica headwaters, which can also be due to headwater capture of part of the upper rio Tietê. This is the first record of Coptobrycon bilineatus in the coastal drainage, hitherto restricted to the upper Paraná river system. The distribution of Taunaya bifasciata and Pseudotocinclus tietensis is also extended. The fauna sharing found here confirms the biogeographical common history hypothesis among southeastern coastal and Brazilian Shield drainages.Keywords: endangered species�� fauna sharing�� conservation�� coastal river�� fauna inventory�� southeastern Brazil. A ictiofauna da planície costeira do leste da América do Sul é pouco conhecida, especialmente em relação aos rios e riachos da Mata Atlântica, existindo regiões pouco exploradas, que podem abrigar espécies raras ou não descritas para a ciência. Exemplo dessa situação é o Parque das Neblinas, uma Reserva Particular do Patrimônio Natural (RPPN) no município de Bertioga, estado de São Paulo, onde nenhum levantamento ictiofaunístico havia sido feito até o presente. A hidrografia do Parque é formada pelo rio Itatinga e seus vários riachos afluentes, que deságuam na bacia do rio Itapanhaú. Foram amostrados nove pontos utilizando peneiras de arroz, redes de arrasto e redes de espera, que resultaram na captura de 1.086 exemplares de peixes, de sete espécies, três ordens e cinco famílias. As espécies mais representativas foram Astyanax paranae, Phalloceros caudimaculatus e Coptobrycon bilineatus. Resumo

TRAJANO, E., SECUTTI, S. & BICHUETTE, M.E. Natural history and population data of fishes in caves of the Serra do Ramalho karst area, Middle São Francisco basin, northeastern Brazil. Biota Neotrop., 9(1): http://www.biotaneotropica.org.br/v9n1/en/abstract?article+bn02909012009. Abstract:During the exploration and mapping of new caves in Serra do Ramalho karst area, southern Bahia state, cavers from the Grupo Bambuí de Pesquisas Espeleológicas -GBPE (Belo Horizonte) noticed the presence of troglomorphic catfishes (species with reduced eyes and/or melanic pigmentation), which we intensively investigated with regards to their ecology and behavior since 2005. Non-troglomorphic fishes regularly found in the studied caves were included in this investigation. We present here data on the natural history of two troglobitic (exclusively subterranean troglomorphic species) fishes -Rhamdia enfurnada Bichuette & Trajano, 2005 (Heptapteridae; Gruna do Enfurnado) and Trichomycterus undescribed species (Trichomycteridae; Lapa dos Peixes and Gruna da Água Clara), and non-troglomorphic Hoplias cf. malabaricus, probably a troglophile (able to form populations both in epigean and subterranean habitats) in the Gruna do Enfurnado, and Pimelodella sp., a species with a sink population in the Lapa dos Peixes.
