Bioprospecting for Isoetes cangae Endophytes with Potential to Promote Plant Growth. [PDF]
Int J Microbiol, 2023 Isoetes cangae is a native plant found only in a permanent pond in Serra dos Carajás in the Amazon region. Plant‐associated microbial communities are recognized to be responsible for biological processes essential for the health, growth, and even adaptation of plants to environmental stresses.

Distribution and taxonomic identity of the species of Narcine (Toperdiniformes: Narcinidae) in the southwestern Atlantic Ocean. [PDF]
J Fish BiolAbstract The genus Narcine is the most diverse among electric rays of the order Torpediniformes and is also the only electric ray genus with more than one species occurring in South American waters: Narcine brasiliensis and Narcine bancroftii. The first species has been historically described as distributed from Brazil's southeast coast down to ...

Polymer Engineering &Science, Volume 63, Issue 12, Page 4127-4139, December 2023., 2023 The OH polyol groups mainly controls film‐forming and film properties. Abstract Polysaccharide films are alternative sources to replace fossil‐based compounds. This study aimed to use rice starch modified by gelatinization and oxidation processes. Different properties were observed after blending it with chitosan and polyols, as evaluated on the film ...

Ecology Letters, Volume 26, Issue 12, Page 2122-2134, December 2023., 2023 The influence of aquatic resource‐inputs on terrestrial communities is poorly understood, particularly in the tropics. Using stable isotopes to trace aquatic prey use and quantify the impact on trophic structure in 240 riparian arthropod communities in tropical and temperate forests, we found riparian predators consumed more aquatic prey and were more ...

Gas Chromatography Coupled to High Resolution Time-of-Flight Mass Spectrometry as a High-Throughput Tool for Characterizing Geochemical Biomarkers in Sediments. [PDF]
Int J Anal Chem, 2018 The performance of gas chromatography coupled to high‐resolution time‐of‐flight mass spectrometry (GC‐HRTofMS) for characterizing geochemical biomarkers from sediment samples was evaluated. Two approaches to obtain the geochemical biomarkers were tested: (1) extraction with organic solvent and subsequent derivatization and (2) in‐situ derivatization ...

Evolutionary Applications, Volume 16, Issue 2, Page 428-460, February 2023., 2023 Abstract By applying morphological and molecular data on two genera of the nudibranch molluscs it is shown that the tension between taxonomic practice and evolutionary processes persists. A review of the related genera Catriona and Tenellia is used to demonstrate that the fine‐scale taxonomic differentiation is an important tool in the integration of ...

Ecology, Volume 103, Issue 9, September 2022., 2022 Abstract The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time

Seasonal dynamics of mesozooplankton biomass over a sub‐Arctic continental shelf
Ecology and Evolution, Volume 11, Issue 13, Page 8713-8729, July 2021., 2021 Mesozooplankton play a key role as the major trophic link between the pelagic primary producers and higher trophic levels. Here, we show that meroplankton, the planktonic larvae of benthic invertebrates, contribute considerably to the biomass of the smallest mesozooplankton size fraction (<1 mm) during spring, the period of first feeding for most major

Determinants of Cyanobacteria and Algae Diversity in Natural Freshwater Micro-Ecosystems. [PDF]
Environ MicrobiolThe Shannon Index, turbidity and luminosity negatively affected the LCBD, species with intermediate frequency of occurrence affected the LCBD, cyanobacteria and green algae are the groups that contribute most to the SCBD, as well as species with accessory frequency.

Anurofauna de restinga do Lagamar Paulista, São Paulo, Brasil [PDF]
, 2012 Insular habitats are considered ideal for biogeographic studies, as they represent almost closed habitats with known formation timelines. Although São Paulo state in Brazil has a large number of continental and oceanic islands, few studies have examined ...
