This study evaluated the adaptive responses of dark-coated Canindé and light-coated Moxotó goats reared under semiarid conditions in Brazilian semiarid through an integrated assessment of thermoregulatory, biochemical, hormonal, and morphological variables. Sixty non-pregnant and non-lactating goats (30 Canindé and 30 Moxotó) were evaluated during summer and winter under the same grazing and management conditions. Animals rece...
In its early years, the UN Decade on Ecosystem Restoration has mobilized unprecedented global commitments. Yet, measuring restoration success remains contested, particularly in megadiverse countries where the absence of standardized indicators and assessment protocols often leads to subjective decisions by environmental agencies. Here, we present a core set of leading indicators developed through a pioneering Brazil-led scienc...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Hydrochars from waste biomass of açaí and curauá as adsorbents for methylene blue using factorial experimental designNARA Subscribed
This study investigated the performance of four hydrochars derived from açaí seeds and curauá mucilage for methylene blue (MB) removal from aqueous solutions. Untreated (AWR, CWR) and phosphoric acid-treated (AAR, CAR) hydrochars were produced via hydrothermal carbonization and comprehensively characterized by Boehm titration, pH pzc , FTIR, SEM, TG/DTG, surface area, and elemental analyses. A 2 3 - factorial experimental desi...
Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric dammingNARA Subscribed
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 River, and stomach contents of 134 specimens were analysed. The diet was predominantly c...
