Abstract The urban areas have suffered with the loss in their biodiversity along the years due to the decrease of green areas by civil construction or by the urban population growth. Therefore, this work aimed at registering the angiosperms diversity in an urban forest fragment at the Itaperi Campus of the State University of Ceará, Fortaleza, Brazil. The sampling was carried out from May/2018 to April /2019 through walks during the rainy and dry seasons. 160 species distributed in 128 genera and 49 families were registered. Fabaceae (27 spp.), Asteraceae (13 spp.), Convolvulaceae and Malvaceae (11 spp. each), Rubiaceae e Poaceae (9 spp. each), and Euphorbiaceae (8 spp.) were the richest families, accounting for 55% of the sampled flora. The herbaceous plants (36.65%) were the most represented habit after which the sub-shrubs and shrubs (17,50% each), arboreal (16,25%) and climbing plants (13.12%) were classified. Among the total species 94.37% are natives, 15,62% are endemic to Brazil and 5,62% are exotic. Of the identified species, 10 spp. are in the Red List of the Flora Conservation National Center and 30 spp. are in the Red List of the International Union for the Conservation of Nature. It can be concluded that the studied fragment has an important richness of plant species in an urban area, therefore it is necessary to create a Conservation Unity and a management plan in order to guarantee the conservation of the area.

Vascular Epiphytes

Vascular epiphytes are one of the most important forest components, contributing to microclimatic maintenance. These plants find ideal conditions for development in the Amazon due to the spatial heterogeneity and high temperature and humidity typical of this biome. In recent years, the Brazilian Amazon has undergone dramatic changes in its landscape, mainly due to the increase in deforestation and fire rates. We present here the floristic composition and analyze the community structure of epiphytic angiosperms of an urban forest fragment in Eastern Amazon. A total of 71 epiphytic individuals were recorded belonging to eight species and four families. Orchidaceae was the most representative family, corroborating the pattern for surveys of epiphytic diversity in the Neotropical region. Epiphytic species were found on 24 individuals of 10 tree species. The epiphytic importance value (IVe) was low for all species, except for Aechmea tocantina and Rhipsalis baccifera. Cactaceae was the family with the highest IVe. Most epiphytes were found in the crown of trees (83.1%). The diversity index of the fragment was H’ = 1.80 and the equity index was J= 0.87, reflecting the absence of highly dominant species. Conservation of urban forest fragments is necessary for the maintenance of epiphytic flora and ecosystem services.

Original Vegetation

Humans have altered the forests of urban regions drastically, thereby reducing the original forests to isolated fragments. Such fragments may contain remnants of the original vegetation. Nanmangalam Reserve Forest (NRF), located in the Metropolitan Chennai, Tamil Nadu, India, is an example of such a forest fragment, covering an area of 321 ha. A total of 449 angiosperm species belonging to 313 genera representing 83 families were recorded from NRF. Amongst the species, 79% were dicots and 21% were monocots. The most genera/species rich families were Fabaceae (37/69) and Poaceae (34/52). The species rich genera included Cassia (10), Crotalaria (7), Erogrostis, Hedyotis and Phyllanthus (6 each). Six endemic species were recorded. This diversity amidst a rapidly expanding city has to be protected in order to enable the conservation agenda of urban areas.

Southwestern Amazonia

Vascular epiphytes are common in tropical forests and represent a considerable part of the biodiversity in Southwestern Amazonia. The aim of this study was to determine the floristic composition, patterns of species richness, and geographical distribution and knowledge gaps (collection effort) of the epiphytic vascular flora of the Brazilian State of Acre. We analyzed the database of the Flora of Acre and found a total of 331 species and 32 families of angiosperms and ferns. Almost half of the epiphytic flora of Acre (48% of species) occurs only in Northern Brazil. Of the total species, 56% are restricted to Amazonia. The distribution of the number of collections of epiphytes is concentrated in a few locations in the state and there is a positive correlation between the number of collections of epiphytes and the general index of collection density. The low and unequal sampling effort of epiphytes across the State, the high proportion of specimens identified at best to genus, and the still steep species/sampling curve indicates that the true diversity of epiphytes in Southwestern Amazonia is expressively higher than recorded thus far. This highlights the need for efforts specifically focused on documenting under-represented taxonomic groups as well as more thorough inventory of the canopy flora in this region of Amazonia.

ABSTRACT We present a synthesis (2006-2012) of plant community dynamics in an area (1 ha) of the largest remnant of Atlantic Rain Forest surrounded by São Paulo city. Plants with ≥ 2.5 cm dbh, including the climbers, were sampled in 10 transects (2 × 50 m), and the smaller (> 1 m height, < 2.5 cm dbh) in 10 subtransects (1 × 50 m). We sampled 901 individuals, 125 species (38 families), 83 classified as late-successional species, 12 threatened with extinction and 56 absent in the area management plan, some Endangered (EN) species. The climbers were the most dynamics, they had the largest decrease in basal area; and the larger (> 5.0 cm dbh) and shorter (< 2.5 cm dbh) trees had the highest mortality rates of the shrub-tree synusia. Late species regeneration was predominant. The studied forest showed progression towards more mature successional stages in the monitoring period.

History Of

There are few studies dedicated to the natural history of Neotropical spider wasps (Pompilidae). When it comes to urban areas, the knowledge on these wasps is even scarcer. This study sheds light on the natural history of Auplopus cf. rufipes and A. cf. brasiliensis (Hymenoptera: Pompilidae: Ageniellini) from an urban Atlantic Forest fragment in the Rio de Janeiro Botanical Garden, Rio de Janeiro City, Brazil. Auplopus cf. rufipes displays a multivoltine pattern and frequently nests in bamboo canes scattered in the open areas, whereas A. cf. brasiliensis is a rare sight, with only a single nest collected from a hose trap-nest. Females of the former species show aggressive behaviour, which suggests a solitary lifestyle. Their nests were partly enveloped in a complex structure, similar to other species that build free-standing, unconcealed nests and display some degree of sociality. Such behaviour could not be observed for A. cf. brasiliensis. Despite that, nests of both species were built using mud pellets, though the brood cells differed regarding arrangement and position in the trap. Two parasites were found attacking the cells: Caenochrysis crotonis (Chrysididae) in a cell of A. cf. rufipes, and Chaenotetrastichus neotropicalis (Eulophidae) in two cells of A. cf. brasiliensis, both recorded for the first time. Auplopus cf. rufipes was found to prey on Frigga cf. quintensis (Salticidae), the first record of this genus as a host of Auplopus.

The silvicultural principles of a forest management plan for Canton Neuchâtel reveals itself as steeped in a systemic approach that allows us to consider the forest as a truly living system. In this context, it seems judicious to the author to conceive of the body forest personnel as a group of responsible people who share certain common ethics and who, in their work, promote the emergence of collective services recognised as beneficial to the state and which would be supported by public funding for the good of the entire community.

Stress negatively affects the mental health of students, causes anxiety and depression, leads to poor academic performance, lowers level of professional training and success in the future. The purpose of the research is to study the state of mental health of medical students to develop recommendations for the prevention of maladaptation. Materials and methods. 252 5-year students aged 20–29 (22 ± 1,1) years, 168 (66,7 %) females and 84 (33,3 %) males (137 students of Belgorod State University and 115 of Altay State Medical University (ASMU)) were examined by medico-sociological and psychometric methods. Results. It was established that every fifth student of the Belgorod State University and every third of the ASMU did not enter the medical university on their own initiative. Less than half (43 %) of Belgorod State University students and 30.4 % of the ASMU ones are convinced that the choice of profession was correct, 35 and 37.4 % are, consequently, completely disappointed with it. Students of Belgorod State University dealt with training stress factors poorer and, as a result, have more pronounced mental symptoms of training stress, difficulties in organizing the daily regimen, irregular nutrition, and fear of the future. Regardless of the region of studying, the number of students not committed to the medical profession, after 5 years of study, is more than 3 times higher among those who enter the university not on their own initiative. Students of the ASMU hit substances, skipped classes, played computer games and took sedative drugs more often to overcome academic stress. The degree of anxiety before the exams in students of Belgorod State University was higher (9 points) than in their peers from the State Medical University (7 points). An extremely high (8–10 points) level of anxiety before exams was characteristic of 75,9 and 44,3 % of students, respectively. The former were more likely to experience clinically significant panic attacks: 27,7 and 6,1 %. Conclusion. Given the high incidence of social phobia (19,1–24,1 %), depression (22,6–32,2 %) and anxiety (21,9– 27,8 %) among medical students, the development and implementation of psycho-correctional programs aimed at the formation of adaptive ways to overcome stress, reduce anxiety and depression is required. This will prevent the development of psychosomatic disorders and addictions.
