Tel: + 55-19-3788 7292; fax: +55-19-3289 3124; e-mail: [email protected] Abstract - The trichomycterid catfishes known as candirus are renowned for their blood feeding, but information on their habits under natural conditions is very fragmentary and generally restricted to hosts or habitats. We recorded an undescribed species of the vandelliine genus Paracanthopoma riding the giant jau catfish, Zungaro zungaro (Pimelodidae), in the upper Amazon. The candirus were found on the host’s caudal and pectoral fins, as well as the base of the dorsal fin, with their snouts buried up to the eyes in the tough skin of the catfish host. All of them had small amounts of partly digested blood in the distal part of the gut. Along the host’s dorsal fin base we found a few additional tiny holes, most of them healed. We suggest that Paracanthopoma feeds on the gill chamber of its hosts, and that the individuals we found were taking a ride partly buried into the host’s skin. -

The Microhabitat, Behavior and Diet of Centromochlus Meridionalis, a Small Catfish of Amazon Streams (Teleostei: Auchenipteridae)

Freshwaters, Vol. 26, No. 3, pp. 221-228, 2 figs., 2 tabs., November 2015 © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 The microhabitat, behavior and diet of Centromochlus meridionalis, a small catfish of Amazon streams (Teleostei: Auchenipteridae) Fernando Gonçalves Cabeceira*, Denise Caragnato Parisotto**, Jansen Zuanon***, Alberto Akama**** and Lucélia Nobre Carvalho*, ** Centromochlus meridionalis was recently described from streams of Brazilian Amazon. The marbled dark brown and black color pattern together with the use of submersed leaf litter accumulations for shelter differentiates this species among its congeners. We present information about the biology of C. meridionalis based on data gathered in streams and under captivity, as well as on a dietary analysis. Behavioral observations were made in captivity (aquaria). Dietary analysis was performed based on stomach contents of 38 specimens. The species was found in 8 out of 12 small streams sampled, where specimens were captured predominantly amidst submerged leaf litter. Nine types of behavioral acts were identified, of which “swimming near the substratum” and “charging the substratum for food” were the most frequent. Thirty (~ 79 %) out of the 38 stomachs had food, and the diet was composed of 27 types of food items. Centromochlus meridionalis can be considered a generalist microcarnivore, consuming predominantly authochtonous and allochtonous insects, and other terrestrial invertebrates, crustaceans and fish as well. The use of different water column strata during foraging and the diversity of food items consumed indicate that this small catfish utilizes several feeding tactics.

Of the 48 species previously considered valid in the subfamily, only one, Centromochlus steindachneri, was not evaluated in the present study. The phylogenetic analysis generated two most parsimonious trees, each with 202 steps, that support the monophyly of Centromochlinae composed of five valid genera: Glanidium, Gephyromochlus, Gelanoglanis, Centromochlus and Tatia. Although those five genera form a clade sister to the monotypic Pseudotatia, we exclude Pseudotatia from Centromochlinae. The parsimony analysis placed Glanidium (six species) as the sister group to all other species of Centromochlinae. Gephyromochlus contained a single species, Gephyromochlus leopardus, that is sister to the clade Gelanoglanis (five species) + Centromochlus (eight species). -

GCorresponding author. Email: [email protected] Abstract. This study investigates the reef fish community structure of the world’s smallest remote tropical island, the St Peter and St Paul’s Archipelago, in the equatorial Atlantic. The interplay between isolation, high endemism and low species richness makes the St Peter and St Paul’s Archipelago ecologically simpler than larger and highly connected shelf reef systems, making it an important natural laboratory for ecology and biogeography, particularly with respect to the effects of abiotic and biotic factors, and the functional organisation of such a depauperate community. Boosted regression trees were used to associate density, biomass and diversity of reef fishes with six abiotic and biotic variables, considering the community both as a whole and segregated into seven trophic groups. -

Amazon Alive!
Amazon Alive! A decade of discovery 1999-2009 The Amazon is the planet’s largest rainforest and river basin. It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered. Owing to the sheer number of the latter, these are not covered in detail by this report. This report has tried to be comprehensive in its listing of new plants and vertebrates described from the Amazon biome in the last decade. But for the largest groups of life on Earth, such as invertebrates, such lists do not exist – so the number of new species presented here is no doubt an underestimate.

Taxonomia E Filogenia De Peixes De Riachos Brasileiros
Oecologia Australis 25(2):197–230, 2021 https://doi.org/10.4257/oeco.2021.2502.01 TAXONOMIA E FILOGENIA DE PEIXES DE RIACHOS BRASILEIROS Paulo Andreas Buckup1* 1 Universidade Federal do Rio de Janeiro, Museu Nacional, Quinta da Boa Vista, CEP 20940-040, Rio de Janeiro, RJ, Brasil. E-mail: [email protected] (*autor correspondente). Resumo: A fauna de peixes de riachos brasileiros compreende 36 famílias de peixes teleósteos de água doce. O conhecimento sobre a sistemática e filogenia deste conjunto de espécies ampliou-se consideravelmente nas últimas duas décadas, porém ainda é muito heterogêneo, havendo grupos sobre os quais pouco se conhece, assim como grupos para os quais há chaves de identificação e hipóteses filogenéticas recentes e bem documentadas. O número de famílias de peixes de água doce com presença frequente em riachos brasileiros ampliou-se de 31 para 36. Este crescimento no conhecimento da diversidade dos peixes neotropicais refletiu-se no grande desenvolvimento das hipóteses sobre sua evolução e contribuiu para o entendimento da história filogenética e estruturação das comunidades de peixes de riacho. Palavras-chave: biodiversidade; classificação; filogenia; riachos; sistemática. TAXONOMY AND PHYLOGENY OF FISHES FROM BRAZILIAN SMALL STREAMS: The fish fauna occurring in Brazilian small streams comprises 36 families of teleost freshwater fishes. The systematics and phylogenetic knowledge about this fauna greatly expanded during the last two decades, but is still very heterogeneous. For some taxonomic groups there are taxonomic identification keys and well-documented phylogenetic hypotheses, while other groups are mostly comprised by poorly known species. The increase in the knowledge of Neotropical fish diversity was associated with the significant growth of hypotheses about their evolution and contributed to the understanding of the phylogenetic history of fish comunities and their structure in small streams.
