Fishers’ local ecological knowledge reveals human dimensions of the Araguaian river dolphin, an endemic and threatened megafauna species in the Brazilian Amazon
Aquatic mammals are ecologically important apex predators that regulate aquatic food webs but are increasingly threatened by multiple anthropogenic pressures. Improving knowledge of threatened species is therefore essential to support effective conservation. We employed fishers’ local ecological knowledge (LEK) to investigate the conservation and human dimensions of the Araguaian river dolphin ( Inia araguaiaensis ) in the Tocantins–Araguaia Basi…

Fishers' knowledge on the ecology, impacts and benefits of the non-native peacock bass Cichla kelberi in a coastal river in southeastern Brazil
Ethnoichthyology has been used to understand how humans perceive environmental changes, including species introductions. In Rio de Janeiro State, southeastern Brazil, fishers introduced juveniles of peacock bass Cichla kelberi in the Juturnaíba Reservoir in the 1990's. In the last years, this fish started to be caught in the São João River, downstream of the dam. This study aimed to identify whether fishers recognize the potential impact of the p…

Aplicabilidade, potenciais e desafios dos Pagamentos por Serviços Ambientais para conservação da água no sul do Brasil
Os Pagamentos por Serviços Ambientais (PSA) se inserem num contexto global em que a economia de mercado não pode mais desconsiderar os recursos e usos da natureza, tendo que considerá-la como um de seus componentes, a fim de que os seres humanos possam exercer suas atividades de forma não nociva aos ecossistemas. Nesse sentido, práticas de incentivo que estimulem ou reforcem atitudes conservacionistas são essenciais. Para se considerar os PSA efe…
Fishers' knowledge on the coast of Brazil
BACKGROUND: Although fishers' knowledge has been recently considered into management programmes, there is still the need to establish a better understanding of fishers' perceptions and cognition. Fishers can provide novel information on the biology and ecology of species, which can potentially be used in the management of fisheries. The knowledge fishers have and how they classify nature is empirically based. It is common, for example, to observe…
Fishers' knowledge about fish trophic interactions in the southeastern Brazilian coast
BACKGROUND: Data derived from studies of fishers' local ecological knowledge (LEK) can be invaluable to the proposal of new studies and more appropriate management strategies. This study analyzed the fisher's LEK about trophic relationships of fishes in the southeastern Brazilian coast, comparing fishers' LEK with scientific knowledge to provide new hypotheses. METHODS: The initial contacts with fishers were made through informal visits in their …
Global pressures, specific responses
We assessed the effects of nutrient enrichment on three stream ecosystems running through distinct biomes (Mediterranean, Pampean and Andean). We increased the concentrations of N and P in the stream water 1.6–4-fold following a before–after control–impact paired series (BACIPS) design in each stream, and evaluated changes in the biomass of bacteria, primary producers, invertebrates and fish in the enriched (E) versus control (C) reaches after nu…
The paraty artisanal fishery (southeastern Brazilian coast)
This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1) to describe the Paraty fishery; 2) to compare the fishermen's local ecological knowledge with recorded fish landings and previous studies in Paraty; 3) to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological…
Ethnobiology of snappers (Lutjanidae)
In this study, we sought to investigate the biology (diet and reproduction) and ethnobiology (fishers knowledge and fishing spots used to catch snappers) of five species of snappers (Lutjanidae), including Lutjanus analis, Lutjanus synagris, Lutjanus vivanus, Ocyurus chrysurus, and Romboplites saliens at five sites along the northeast (Riacho Doce, Maceió in Alagoas State, and Porto do Sauípe, Entre Rios at Bahia State) and the southeast (SE) Bra…
Fishing Strategies and Niche Partitioning Among Coastal Fishers in Southern Brazil
Ecology and ethnoecology of dusky grouper [garoupa, Epinephelus marginatus (Lowe, 1834)] along the coast of Brazil
Dusky grouper (garoupa, Epinephelus marginatus) is an important catch for several artisanal small-scale fisheries along the Brazilian coast. It is a sedentary, monandric, and late maturing protogynous species, which makes it vulnerable to overharvesting even though it is mainly caught through hook and line or spear fishing through free diving. Lack of information on the ecology and biology of this species in Brazil is astonishing. Much of the inf…
Are Biological Species and Higher-Ranking Categories Real? Fish Folk Taxonomy on Brazil's Atlantic Forest Coast and in the Amazon
Analysis of Brazilian fishers` classifications of 24 marine (Atlantic coast) and 24 freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify fish mainly through generic names (primary lexemes), while riverine Amazonian fishers typically identify them through binomials. The similarity of Amazonian fish species seems to contribute to the detailed folk taxonomy used by riverine fishers. High-ranking groups called "relat…
