A neuroplasticidade refere-se à capacidade do sistema nervoso de reorganizar sua estrutura e função em resposta a experiências estímulos ambientais. Evidências sugerem que alterações nos processos estão envolvidas na etiologia progressão diversos transtornos psiquiátricos, como depressão, esquizofrenia transtorno bipolar. Este estudo tem objetivo revisar sistematicamente literatura sobre relação entre destacando os mecanismos subjacentes implicações terapêuticas. Para tanto, foram...
Abstract: Studies on ichthyoplankton ecology become essential when one realizes the importance and influence of this component in dynamics, conservation, maintenance fishery resources. However, ecological information about subject is still scarce has not been properly valued used by environmental managers decision-makers. In study, we present state art research Amazon region. The number studies increasing over time but they are restricted. We hope study may encourage related to
Abstract We described the early development of Myloplus asterias and M. lobatus, two fish species Serrasalmidae using morphological, meristic, morphometric characteristics. These herbivores serrasalmids are heavily fished because their commercial importance in Amazon. The individuals were collected between 2016 2020 limnetic zone open water macrophyte stands Lower Amazon River floodplain. tested different growth models to identify pattern these species. During initial ontogeny, can be...
Egg and larvae drift is a key mechanism for early fish stages to colonize nursery growth areas provides insights into ichthyofauna spawning times locations—crucial information understanding biology. In the Tapajós River, Amazon Basin, no study has investigated of ichthyoplankton along hydrological phases nor occurrence dispersion plastic waste associated with plankton. Thus, we aimed present an overview spatio-temporal in this river. Temporal sampling was carried out spatial gradient...

A total 93 individuals, 83 larvae 10 were analyzed, they captured monthly between 2014 2019 channel macrophytes aquatic stands alluvial plains located River. From each specimen, morphometric meristic data measured then growth pattern variables analyzed. The have an elongated...
The initial ontogeny of black prochilodus (Prochilodus nigricans Spix & Agassiz 1829) was described through morphological, meristic and morphometric characters. biological material used from captivity. 41 eggs, 151 larvae 10 juveniles were analysed. eggs spherical, transparent, nonadhesive pelagic, with a wide perivitelline space an average diameter 2.62 mm. Hatching occurs between 17 18 h after fertilization. standard length varied 3.28 to 26.73 mm that 28.99 42.90 showed elongated fusiform...
The reproduction of neotropical fish is linked to environmental stimuli that act as triggers in this process. Thus, it possible affirm specific changes can delimit most fish’s period and reproductive success. El Niño Southern Oscillation phenomena (ENSO) influence rainfall and, consequently, hydrological dynamics, affecting several population aspects, especially aspects. However, the Amazon, empirical evidence effect anomalous climatic events on incipient. In sense, we investigated taxonomic...
O estudo descreve a composição e estrutura da comunidade de larvas juvenis peixes associada bancos macrófitas aquáticas avalia importância dessas vegetações para o desenvolvimento dos estágios iniciais vida ictiofauna em uma ilha aluvial no Baixo Amazonas, Pará, Brasil. As amostragens foram realizadas durante os momentos cheia/vazante 2017 (ciclo I) enchente 2018 II) por meio um peneirão (malha 500 µm). Em laboratório indivíduos identificados classificados quanto ao seu estágio verificada...
Abstract This study assessed the phenology and functional structure of parental stocks fish larvae, evaluated how species modulate their reproductive activities as a function natural hydrological regimes in lower Amazon River, Brazil. Larvae were collected using conical plankton nets monthly over two cycles between January December 2013, May 2017 April 2018. The collections conducted around an alluvial island located near municipality Santarém, Pará, After identification, individuals...
Background. This study analyzed the variation of abundance and spatial distribution fish eggs larvae sampled from December 2017 to April 2018 along approximately 23 km in downstream/upstream direction (departing city Santarém) lower stretch Amazon River, with emphasis on gradients: vertical (subsurface depth) horizontal (in mid channel shore proximity). Materials methods. Fish were collected at six sampling stations, each representing channel, proximity areas, both subsurface (by means...
Many Amazonian fish' reproduction is associated to seasonality and the conditions of habitat integrity. In a Neotropical floodplain lake Amazon region, temporal structure ichthyoplankton was investigated hypothesis that density fish eggs larvae diversity species vary between two areas with different levels environmental changes occurred tested. The sampling monthly September 2017 August 2018. Six stations were used, distributed in locations close far from altered area. 195 1,785 nine orders...
