Abstract This study evaluated the richness of vascular epiphytes on Pseudobombax sp. nov. in three inselbergs in the Atlantic Forest Domain in state of Espírito Santo and evaluated the floristic similarity between the areas. We sampled 111 phorophytes in three regions in the southern of Espírito Santo state and identified 151 species, 77 genera and 21 families of vascular epiphytes, of which the families Orchidaceae and Bromeliaceae showed the highest richness. Non-parametric estimators (Chao 2, Jackknife 1) indicate that 90 and 95% of species richness of epiphytes was recorded. The most diversified ecological category was the characteristic holoepiphytes. The ratio of the number of epiphytes and number of phorophytes sampled in a montane inselberg, in this study, was greater than the richness of vascular epiphytes found in the rocky outcrops of quartzite, and, in general, different types of Atlantic Domain forests, but smaller in richness for some Dense Ombrophilous Forests of southern Brazil. The three inselberg areas had distinct floras. The high richness, the endemism found, and the number of endangered species of epiphytes demonstrate the important role of Pseudobombax sp. nov., because of its architecture and size, in the maintenance of biodiversity on the inselbergs in southeastern Brazil.

The role of morphodynamic features such as grain size, swash climate and wave action on the macrofauna of beaches are well-known. However, few studies have investigated natural disturbances as potential drivers of temporal community variations. In southeastern Brazil, we sampled the intertidal macrofauna of two sandy beaches to test whether seasonal disturbances as the frequency of storm wave events (SWE) and rainfall have significant influence on their composition and abundance. The macrofauna assemblage differed significantly between the rainy and the dry seasons, but rainfall was not the main driver of community changes, although both beaches are in the vicinity of extensive river plumes. Actually, SWE explained most macrofauna richness overtime, with positive effects. Our results point to the importance of learning more about the effects of poorly studied disturbances on macrofaunal communities, and based on them we strongly recommend including these seasonal phenomena when monitoring sandy beaches.

Information on the role of smooth-billed anis (Crotophaga ani) as tick-pickers on mammals remains controversial. I record here these birds removing ticks and pecking at wounds of capybaras (Hydrochoerus hydrochaeris) in a small reserve at Campinas, São Paulo, southeastern Brazil. The birds inspected the mammals’ skin, both in places with and without hair. The hair was parted with bill movements, and ticks were removed by vigorous pulling. The birds also pecked at open or healing sores, from which they extracted small portions of blood clots and dead tissue. The capybaras appeared oblivious to the birds’ activity. Even in the case that the cleaning behaviour is restricted to some bird individuals and populations, or places and periods, this record validates the notion that smooth-billed anis removes ticks from herbivorous mammals.

The article presents an overview of the international conference Russia and ASEAN in Asia-Pacific Region: Dynamic of Cooperation, Regional Processes and the Global Context that was held at MGIMO University on October 15-16, 2021. The event was a part of the 13th Russian International Studies Association (RISA) Convention. This year the conference was dedicated to the 25th anniversary of Russia-ASEAN Dialogue Partnership and 30th anniversary of their bilateral relations. The overview is focused on the presentations, covering Russia-Vietnam relations and the role of Vietnam in ASEAN-Russia partnership, as well as Vietnams position within the region.
