Abstract: On 22 July 2022, the Universidade do Vale do Rio dos Sinos (Unisinos), a private institution and community university in southern Brazil, announced the interruption of 12 of its postgraduate programmes, including the Postgraduate Program of Biology (PPG Biologia), whose professors founded the journal, Neotropical Biology and Conservation. We conducted a bibliometric analysis of papers published by PPG Biologia in the past 20 years to assess its impact on biological research at a national level. The number of publications and citations increased constantly over the years, with publications growing exponentially. Although most collaborations with other research programmes occurred inside Brazil, a significant number of studies were co-authored by researchers from other countries from at least four continents. The main research lines focused on biological sciences, ecology, sociology, education, environmental sciences and genetics. Despite being affected by the decrease in research funding and the reduction of personnel, PPG Biologia kept its high impact score according to the national evaluation, above that of most programmes in private universities and similar to public ones. With a team of renowned researchers working on different and sometimes unique research lines, the interruption of PPG Biologia will harm the progress of biological research and conservation across the Neotropical realm.

Influence of environmental and morphological parameters on the microfauna community present in phytotelmata of a bromeliad in a fragment of Atlantic Forest, southern Brazil https://neotropical.pensoft.net/article/56186/ Neotropical Biology and Conservation 16(1): 59-70

Abstract: Bromeliads are important epiphytes due to their abundance in the Neotropical region and morphological complexity. Their compact and imbricated leaf bases form water storage cisterns that promote important resources for colonization by several prokaryotic and eukaryotic microorganisms. Due to the lack of knowledge about these environments, the objective of the study was to investigate which physical-chemical and ecological parameters exert effects on the biological richness present in the cisterns of Vriesea platynema. The study was carried out in the Center for Research and Nature Conservation (CPCN – Pró-Mata), in the Serra Geral plateau, northeastern Rio Grande do Sul, Brazil. Active searches were performed for 10 trees with bromeliads fixed at two heights (< 1.5 m and > 2.5 m). For each bromeliad individual, the height in relation to the ground, the diameter and depth of the central cistern, water temperature, number of lateral cisterns and number of adjacent bromeliads, were measured. A total of 23 taxa were identified in the phytotelmata of V. platynema, with Philodina, Lambornella, Paramecium, Tetrahymena and Diptera larvae being the most representative groups. The richness of organisms in the phytotelmata presented a positive correlation with water temperature (p = 0.01), and the number of adjacent bromeliads (p = 0.05), indicating that physicochemical and ecological factors could influence the richness of bromeliad biota.
