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.

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.

Intensive botanical survey was done more than two decades on Tropical Dry Evergreen Forest from four coastal districts viz. Cuddalore, Kancheepurm, Nagai and Villupuram of Tamil Nadu and Union Territory of Pondicherry. A total of 87 protected (hillocks, reserve forest) and unprotected (sacred groves, unclassified vegetation) sites were regularly studied from five districts. From this study 82 endemic taxa were enumerated. In addition 25 endemic species were added for the analysis through literature screening and herbarium consultation from 10 Coromandel coastal districts of Tamil Nadu. In all 107 species were recorded, among them 19 are trees, 18 shrubs, 9 climbers and 61 herbs. Distribution of these endemic species were analysed and categorised into endemic to the country, peninsular India, southern India, Eastern and Western Ghats, state and district level. Interestingly the study found that some endemic species were disjunctly distributed in between districts, states, ghats, climatic regimes and bioregions. The disturbance, threat status and conservation measures of few endemic and IUCN red listed species were also studied and discussed.

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.

This research paper is the part of Research Project entitled “Impact of Elected Women Representatives in the Life and Livelihood of the Women in Rural Areas: With Special Reference to Tiruvannamalai District, Tamil Nadu” funded by University of Madras under UGC-UPE Scheme.The 73rd and 74th amendments of the Constitution of India were made by the government to strengthen the position of women and to create a local-level legal foundation for direct democracy for women in both rural and urban areas. The representation for women in local bodies through reservation policies amendment in Constitution of India has stimulated the political participation of women in rural areas. However, when it’s comes to the argument of whether the women reservation in Panchayati Raj helps or benefits to the life and livelihood development of women as a group? The answer is hypothetical because the studies related to the impact of women representatives of Panchayati Raj in the life and livelihood development of women was very less. Therefore, to fill the gap in existing literature, the present study was conducted among the rural women of Tiruvannamalai district to assess the impact of elected women representatives in the physical and financial and business development of the women in rural areas. The findings revealed that during the last five years because of the women representation in their village Panjayati Raj, the Physical Asset of the rural women were increased or developed moderately (55.8%) and Highly (23.4%) and the Financial and Business Asset of the rural women were increased or developed moderately (60.4%) and Highly (18.7%).

BACKGROUND Hand size measurements are commonly used references when instruments are not available and still practiced in rural and even in urban areas of Tamil Nadu. Ancient literature evidences have adequate support for their usage. We wanted to correlate hand span length, hand breadth, and hand length with the stature of an individual. We also wanted to compare the level of correlation of hand span length between males and females. METHODS 214 students were recruited for this study as a convenient sample size. Male students were 122, females were 92. They were aged between 18 - 23 years of Shri Sathya Sai Medical College and Research Institute. Hand span is the distance between tips of the casually extended pollex and minimus. RESULTS The results of Pearson’s correlations were moderately significant between height and the hand breadth (0.315), between height and weight (0.340), and between height and hand length (0.387). The extent of correlation was significant between height and the hand span (0.954) in case of males. In case of females, value of the correlation was also moderately significant between height and the hand breadth (0.619), between height and weight (0.392), between height and hand length (0.515) and between height and the hand span (0.973). CONCLUSIONS The stature was reliably estimated from the hand span length, and the same could be applied for the medicolegal, and forensic purposes.

Social sanctions can be effective for sustaining beneficial norms by harnessing the power of social pressure and peer monitoring. Yet, field evidence regarding how norms might be linked to perceived risk of sanction is limited. In this study, we focused on communities located in peri-urban areas of Tamil Nadu, India, and examined how people’s perceived prevalence of a socially desirable behavior (i.e., toilet use) relates to the perceived risk of sanctions for deviating from this behavior (i.e., open defecation) in the sanitation domain. Cross-sectional data from 2427 participants in 75 communities revealed that the majority (77%, n = 1861) perceived the risk of informal sanctions related to open defecation. Among those, verbal reprimand was the most common (60%), followed by advice (30%) and gossip (7%). Results from multilevel logistic regression indicated that those who believed toilet use was prevalent in their community were more likely to perceive the risk of social sanctions for open defecation. Moderation analysis revealed that this relationship was robust among women, but attenuated among men. Our findings suggest that women are more likely to expect social sanctions if they deviate from what is perceived as the prevalent sanitation behavior (e.g., toilet use) in their community. Open defecation practices are known to cause psychosocial stress among women due to their experiences with sanitation insecurity, which may include fear of disapproval from community members. Our results highlight the need for gendered intervention strategies when sanitation programs leverage social influence for behavior change.

Urban areas, as cities, are frequently overlooked as refuges for the native fauna. However, these places may support several species and house relevant biodiversity contributing to important ecosystemic functions. Wasps and bees (Hymenoptera: Apocrita) are important faunistic elements acting as predators/parasitoids and pollinators, respectively. Therefore, they must be surveyed and inventoried for conservation purposes, especially in cities located in the Atlantic Forest domain, a ravaged Brazilian biome. Accordingly, this study presents a species list of trap-nesting bees and wasps that occurs at the Jardim Botânico do Rio de Janeiro. The survey was conducted using the trap-nest method. Three types of trap-nests were offered totalizing 1,038 traps: rubber hose, bamboo cane and plastic straw. The plastic straw traps were the most effective followed by the bamboo cane ones at attracting nesting wasps and bees. Between April/2017 and February/2019, 12 foundress species built nests: Tetrapedia curvitarsis (Apidae) (33 nests), Hylaeus sp. (Colletidae) (6), Auplopus cf. rufipes (Pompilidae) (5), Trypoxylon sp. (Crabronidae) (4), Pachodynerus nasidens (Vespidae) (3), Auplopus cf. brasiliensis (Pompilidae), Megachile benigna and Megachile sp. (Megachilidae), Euglossa pleosticta, Euglossa sp., and Eufriesea sp. (Apidae) and Penepodium sp. (Sphecidae) all with one nest. Also, four natural enemies were recorded: Chaenotetrastichus neotropicalis (Eulophidae), Gasteruption brachychaetum (Gasterupteiidae), Caenochrysis crotonis (Chrysididae) and Amobia sp. (Diptera: Sarcophagidae). Most bee nests were restrained to the matrix forest and nearby areas, whereas wasps built their nests predominantly in open areas. Regarding seasonality, bees tended to nest in the summer and early autumn influenced by mean temperature, in contrast of wasps that nested in late autumn, winter and spring, influenced by pluviosity. Besides many rare species, which suggests environmental disturbance, the Jardim Botânico do Rio de Janeiro showed a fairly diverse fauna and shows how forest fragment in cities may harbour important representatives of the native fauna.

Background: Diabetes, which was known to be an epidemic in the urban areas, has been found to be increasing rapidly in the rural areas too as a result of the socioeconomic transitions. Diabetes is no longer only a disease of the elderly but is one of the major causes of morbidity and mortality affecting youth and middle aged people.Methods: Screening camp for diabetes was conducted by the Department of Community Medicine in three different areas in the field practice area of Saveetha Medical College and Hospital viz. Thirumazhisai, Kuthambakkam and Velavedu in Thiruvallur district of Tamil Nadu on 7th April 2016 as a part of World Health Day 2016 celebration. Data was collected using a predesigned interview schedule. Descriptive statistics was calculated using rates, ratios & proportions. Univariate analysis was done using Chi square test to find the association between various factors and diabetes status. A parsimonious regression model was developed to find the predictor variables for diabetes.Results: A total of 188 people aged above 18 years attended the screening camps. Majority of the camp attendees were females (62.2%). Proportion of people having diabetes (already diagnosed plus newly screened) was found to be 18.1% out of which 3.2% were screened positive for diabetes. On regression analysis, Intake of alcohol and perceived stress were found to be significantly associated with diabetes (p<0.05).Conclusions: This study highlights a significant burden of undiagnosed cases of diabetes in the community. This indicates the need for systematic screening and awareness programs to identify the undiagnosed cases in the community and offer early life style modifications, treatment and regular follow up to such individuals.
