Bird survey in Thane creek was conducted during winter season in 2015-2016. Total 69 species of birds were encountered belonging to 11 orders and 17 families in the entire creek. As per the IUCN Red list, of the 69 bird species, six near threatened and one vulnerable species were recorded. 60.87 percent birds were migratory winter visitors, 36.23 percent birds were residents and local migrants, and the remaining 2.89 percent birds were residents as well as winter visitors. Scolopacidae family had the highest representation with 14 bird species. Order Phoenicopteriformes had the highest number of individuals (N = 20539) with lesser flamingo contributing 80.22 percent. The Shannon-Weiner diversity indices revealed higher diversity upstream (2.56) followed by midstream (1.78) and downstream (1.12). Similarly, the evenness index showed the species were more evenly distributed upstream (0.219) followed by midstream (0.110) and downstream region (0.060). On the contrary, the dominance was higher downstream (0.501) followed by midstream (0.319) and upstream region (0.124). Order Phoenicopteriformes had the highest percent encounter rate with majority encountered in downstream followed by midstream region and sporadically distributed in the upstream region of the creek. The family with moderate to less number of individuals are majorly encountered in the upstream region of the creek. The birds showed a specific distribution pattern primarily because of food availability and also because of other biotic and abiotic factors.

We analysed the distribution pattern in India, of the agamid lizard Calotes calotes based on localities of the many voucher specimens that we examined, direct field observations by us and literature records. Our preliminary MaxEnt analysis run based on 48 localities revealed that hilly terrain of the Western Ghats and Eastern Ghats are the most ideal regions (>70% prediction) within its range. We also elaborate on the morphology of examined specimens, especially from the eastern parts of its Indian range, viz. the Coromandel Coastal Plains and the Eastern Ghats, so as to categorically confirm its occurrence in eastern parts of Southern India, where its presence had remained equivocal and contentious at best.

Unsustainable commercial exploitation poses a serious threat to many of Vietnam’s native bird species. Here we report on a survey of the country’s online bird trade, conducted across four major online platforms. Between 9 March and 3 April 2020, a total of 434 posts were recorded, accounting for 834 individuals of at least 50 species, ten of which have not been recorded in Vietnamese trade before. Ninety-two percent of the recorded species were native to Vietnam and 18% (n=9) of the species, accounting for 15% (n=115) of the recorded individuals, are protected under Vietnamese law. Recorded prices ranged between VND16,667 (~US$0.7) and VND7 million (~US$303), depending on the species and on a bird’s specific singing qualities. The highest trade numbers were found on Chợ Tốt (186 posts, 335 birds), followed by Facebook (161 posts, 325 birds), Chợ Vinh (82 posts, 169 birds) and Chim Cảnh Đất Việt (5 posts, 5 birds). The scale of the observed trade appears to confirm a partial shift towards online platforms in Vietnam’s bird trade, or at least an increase in the use of online platforms to trade wild birds. In anticipation of a further development of this trend, we urge the Government of Vietnam to improve regulations and to take greater enforcement action against illegal online trading practices.
不可持续的商业开发对越南许多本土鸟类物种构成了严重威胁。在这里，我们报告了一项对该国在线鸟类交易的调查，该调查是在四大在线平台上进行的。在2020年3月9日至4月3日期间，共记录了434个站点，占至少50个物种的834个个体，其中10个之前未在越南贸易中记录。92%的记录物种为越南本土物种，18% (n=9)的物种，占记录个体的15% (n=115)，受越南法律保护。记录的价格在16,667越南盾(约0.7美元)到700万越南盾(约303美元)之间，这取决于鸟类的种类和特定的歌唱品质。交易次数最多的网站依次是:ch结核菌Tốt(186条，335只鸟)、Facebook(161条，325只鸟)、ch结核菌Vinh(82条，169只鸟)、Chim Cảnh Đất Việt(5条，5只鸟)。观察到的交易规模似乎证实了越南鸟类贸易部分转向在线平台，或者至少是使用在线平台交易野生鸟类的情况有所增加。预计这一趋势将进一步发展，我们敦促越南政府改善监管，并对非法网上交易行为采取更大的执法行动。

Earthworms belong to Phylum Annelida, Class Oligochaeta are truly coelomate animals and are known to be swell dwellers. They are exposed to pathogens in the soil. Global in distribution, they reveal biodiversity across India. We have studied the earthworm fauna of India and present here a total distribution of different species of earthworm from India, highlighting their biodiversity and ecology. The study of diversity and earthworm distribution across different states of India and different soil conditions, included under 20 agroeconomic zones (AEZ) of India including 14 families and 445 valid species is an intriguing study, being reported for the first time from India.

The focus of ongoing research in forest ecosystems is highly biased towards vascular epiphytes that grow non-parasitically on host trees and contribute substantially in shaping biodiversity. In this communication, an effort has been made to understand the vascular epiphytic assemblage and richness along the altitudinal gradients in temperate forests of Darjeeling Himalaya. Additionally, influence of environmental variables was also analyzed. Orchidaceae was the dominant family followed by Polypodiaceae and Ericaceae in terms of species abundance. The epiphytic richness and diversity were greater towards lower altitudinal tier compared to the higher. The epiphytic diversity was positively correlated with host tree CBH (circumference at breast height) and bark texture, while bark pH showed a negative correlation. The outcome of this study establishes a baseline of epiphytic characteristics with respect to elevational range and environmental variables in temperate Himalaya. However, a detailed study on population dynamics, habitat evaluation and geographic aspects with further development on monitoring and conservation effort is of utmost necessity.

This study aims to explain Environmental Regulation Modeling in the Halimun Salak Regional Green Economy Efficiency: Empirical Evidence from the National Park which is expected to be a sustainable solution in supporting the creation of a balance between the economic and environmental concepts, especially in the Halimun Salak national park area, Bogor, Indonesia. The research method used is a qualitative method with a grounded theory approach. The results show that the current environmental regulatory modeling has not been successful in implementing green economy efficiency in the salak forest area. This is evidenced by the findings that there are overlapping regulations, low economic income, the increasing population in the salak forest area, and the lack of resolution of legal protection cases. As well as the implementation of environmental policies to date is still in the form of command and control, which causes discrepancies between the parties that are interrelated. As a result, it is necessary to change the environmental policy model for forest areas, namely by using the rational choice theory model. This policy model will become a new solution in implementing increasingly dynamic policies following changes in human behavior and technological developments. Environmental policies that are made must be a role model in an open and dynamic implementation.

The Cabadbaran Mangrove Eco-Park (CaME) intends to rehabilitate and establish eco-tourism through nature immersion and birdlife watching. However, baseline assessment of avifauna is lacking. Thus, this study aimed to identify the composition of diurnal bird species present in the designated mangrove eco-park, determine the diversity, dominance and evenness of the mangrove avifauna, and compare the bird species richness in the three sites. A total of 36 avian species representing 24 families and 9 orders were recorded during the study. Among the 373 individuals documented, 181 were found in abandoned fishponds which is 49% of all bird individuals; while C. hybrida, T. stagnatilis, and E. garzetta were the most abundant species. Shannon-Wiener diversity index revealed that mangrove site (H’=2.78) was the most diverse among the three sites which can be attributed to the presence of lush vegetations. Conversely, dominant species were recorded in the abandoned fishponds which were composed of migratory species mostly. There was a significant difference of species richness in mangrove site compared to other sites since species richness was highly influenced by vegetations. Moreover, this study also documented the first scientific record of migratory species in the area, which could be one of the stopovers of migratory species. Henceforth, the es
