Land use effects on the co-occurrence patterns of streams ichthyofauna in the eastern Amazon by Cleonice M.C. Lobato, Naraiana L. Benone, Leandro S. Brasil, Luciano F.A. Montag

“…Most of the patterns of ichthyofauna co-occurrence occurred at random, composed mainly of rare species, which may be due to the specificity of these species or because the still forested and highly heterogeneous areas of the region may be acting as a mosaic, together with less aggressive land uses such as agriculture, generating these random pairs. …”

Harnessing the Power of Social Media to Obtain Biodiversity Data About Cetaceans in a Poorly Monitored Area by Pedro Morais, Pedro Morais, Luís Afonso, Ester Dias

“…The main disadvantages are the impossibility to obtain georeferenced records from social media, the difficulty to estimate the number of individuals in large groups, and the presence of rare species can be inflated if multiple whale-watching companies report the same individual(s) while they migrate along the coast. …”

Variations of arbuscular mycorrhizal fungi following succession stages in a tropical lowland rainforest ecosystem of South China by Huai Yang, Siwei Mai, Wenjie Liu, Jialin Fu, Qiu Yang, Bin Zhang, Biao Huang

“…We studied community changes in AMF with the succession and explored the impacts of soil physicochemical properties on soil AMF.ResultsOur findings were as follows: (1) Different successional stages showed divergent effects on soil AMF communities. (2) After 40a recovery, the alpha-diversity indices of AMF recovered to the level of secondary forest of 60a, but the similarity of soil AMF communities only recovered to 25.3%. (3) Species richness of common species, rare species, and all the species of AMF showed a significantly positive correlation with soil nitrogen. (4) OTU10; OTU6, OTU9, and OTU141; OTU3 and OTU38; and OTU2, OTU15, OTU23, and OTU197 were significantly unique AMF for grasslands, shrubs, and secondary forests of 40a and 60a, respectively. (5) The phylogenetic tree and the heatmap of AMF showed that the OTUs in grasslands and shrubs were in contrast to the OTUs in secondary forests of 40a and 60a.DiscussionWe concluded that the succession of a secondary forest after deforestation disturbance was probably limited by its AMF community.…”

Patterns of species diversity in a network of artificial islands by Chimalakonda, Deepthi, Chisholm, Ryan A.
