A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

A National Law as an Actor\u2013network: How Guatemala\u2019s General Electricity Law of 1996 Shaped the Country\u2019s Environmental Conflicts over Hydroelectricity [PDF]

open access: yes, 2017
This paper uses controversy mapping to study the history of Guatemala\u2019s General Electricity Law (GGEL, 1996). Particular attention is paid to the impact of the GGEL on social conflicts related to hydroelectricity. This article discusses how an array

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Imposition of Double Charges on Hydroelectric Power Plants

open access: yesSociological Jurisprudence Journal
In meeting electricity needs, there is currently a shift in the use of fossil energy to water energy because fossil energy is no longer available. The use of water as a new renewable energy, as stated in the Electricity Supply Business Plan (RUPTL ...

Evaluation of hydropower upgrade projects - a real options approach [PDF]

open access: yes
When evaluating whether to refurbish existing hydropower plants or invest in a new power plant, there are two important aspects to take into consideration. These are the capacity chosen for the production facilities and the timing of the investment. This

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

open access: yesJournal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Between Dispossession and Inclusion: Land Injustice and Project‐Based Citizenship in the Bagré Irrigation Scheme (Burkina Faso)

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Large‐scale irrigation schemes are central to agrarian transformation in sub‐Saharan Africa, yet their political implications are often reduced to questions of land redistribution or agrarian differentiation. Although existing scholarship has documented how irrigation restructures agrarian relations and generates dispossession, less attention ...
