Repeat LiDAR canopy height models for Borneo, eastern Amazon and Guiana Shield
<p>This repository contains LiDAR canopy height models (CHMS) for six tropical forest sites, derived from repeat LiDAR data. The data were used for analysis of canopy disturbance and recovery dynamics. The years of the data collection differ between sites, so the files are named 'a' for the first scan 'b' for the second scan and 'd' for the difference between scans. The 'dtm' files contain terrain models for these areas. Permanent plots and non-forest areas were masked out prior to analysis. </p>
Rhinella_major_diet_eastern_Amazon
<p>We studied the diet of <em>Rhinella major </em>from temporary lentic water bodies from an urban area in Amapá state, North Brazil. A total of 59 frogs were manually collected between January and May 2019 (rainy season) and analysed using a stomach flushing method. Of these, 42 stomachs revealed 1,236 prey items, of which 1,059 (85.7%) were ants and 177 (14.3%) were other taxa. Isoptera and Coleoptera were the most abundant non-ant taxa. We found a high diversity of ants in the diet (11 genera from five subfamilies), Myrmicinae being the most abundant and frequent ant subfamily, mostly represented by the genera <em>Pheidole </em>and <em>Solenopsis.</em></p>
Data accessibility for conservation implications of genetic structure in the narrowest endemic quillwort from the Eastern Amazon
<p>The quillwort <em>Isoetes cangae</em> is a critically endangered species occurring in a single lake in Serra dos Carajás, Eastern Amazon. Low genetic diversity and small effective population sizes (N<sub>e</sub>) is expected for narrow endemic species (NES). Here, we evaluated genetic diversity, population structure, and N<sub>e</sub> of <em>I. cangae </em>to provide information for conservation programs. Conservation biology studies centered in a single‐species show some limitations but they are still useful considering the limited time and resources available for the protection of species at risk of extinction. Our analyses were based on 55 individuals collected from the Amendoim lake and 35,638 neutral SNPs. Our results indicated a single panmictic population, moderate levels of genetic diversity, and effective population size (N<sub>e</sub>) in the order of thousands, contrasting the expected for NES. Negative FIS values were also found, suggesting that <em>I. cangae</em> is not under risk of inbreeding depression. Our findings imply that <em>I. cangae </em>contains enough genetic diversity to ensure evolutionary potential, all individuals should be treated as one demographic unit.</p>
