Abstract: The distribution of aquatic insects of the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT) can be influenced by factors such as water quality, habitat integrity and biogeography. The present study evaluated the structure of EPT assemblages in streams in the Cerrado, a global biodiversity hotspot. Samples were collected from 20 streams in two protected areas: Parque Estadual do Mirador (10 streams) and Parque Nacional da Chapada das Mesas (10 streams). A total of 1987 specimens were collected, representing 46 taxa of EPT. The two study areas did not differ significantly in taxonomic richness of EPT genera (t = -1.119, p = 0.279) and abundance of individuals (t = 0.268, p = 0.791) but did differ in genus composition (Pseudo-F = 2.088, R2 = 0.103, p = 0.015) and environmental variables (Pseudo-F = 2,282, R2 = 0.112, p = 0.014). None of the tested environmental variables were correlated with the community but a spatial filter captured an effect of the spatial distribution of streams. The region of the study is located in MATOPIBA, which is the last agricultural frontier of the Cerrado. Therefore, it is important that there is police and monitoring so that the “Parque Estadual do Mirador” and the “Parque Nacional da Chapada das Mesas” continue to play their role in conserving biodiversity in the future.

In recent years, the Mycotheca Universitatis Taurinensis (MUT) carried out several research programs aiming to assess the marine fungal biodiversity mainly in the Mediterranean Sea, a biodiversity hotspot in the world. Several biotic and abiotic marine substrates,, were investigated: algae, seagrasses, invertebrates, wood, water and sediments from natural and anthropic sites. The isolated fungi cover all fungal groups, despite taxa belonging to Ascomycetes are predominant. Our results show how marine fungi are ubiquitous in the oceans and play key roles in several niches despite often neglected. Preliminary studies show that, in marine ecosystems as in the terrestrial one, some taxa are ubiquitary while others are specific and closely related to a specific host or substrate. The distribution of the mycobiota in the marine environment is far from being fully described. It is therefore difficult to understand how marine fungi can respond to climate change and/or interact with other marine organisms. To date, marine fungi have been studied principally for the production of secondary metabolites. Despite they shown to be an untapped source of novel molecules of biotechnological importance, almost unknown remains the role of these metabolites in interactions with other organisms that populate the Ocean.

Northeastern India, situated within the Indo-Burma and eastern Himalaya biodiversity hotspot complex, is known for its high diversity of wild felid species.  For most of these species, however, data on distribution and population trends are limited.  Here, we present photographic records of the Marbled Cat Pardofelis marmorata and Asiatic Golden Cat Catopuma temminckii from outside protected areas in the state of Nagaland.  These records are from community forests around the Dzükou Valley in Nagaland and are some of the few records of the species from the state.  The confirmed presence of the two species highlights the pivotal role of community-managed forests in the conservation of endangered species in the region.
