This work uses metagenomic sequencing, for assessing the rhizosphere of the only reported terrestrial mangrove fern Acrostichum aureum Linn. from the Indian Sunderbans. Targeted sequencing of the V3 - V4 region using Illumina Hiseq was performed and the analyses of the sequenced files revealed the presence of a wide variety of microbial members with the highest belonging to Proteobacteria superphyla. We believe that this is the first phylogenetic assessment of the Fern rhizosphere and should provide us with valuable insights into the quality of microbial assemblage available in this particular niche.

An Expert-Based Assessment Model for Evaluating Habitat Suitability of Pond-Breeding Amphibians
sustainability Article An Expert-Based Assessment Model for Evaluating Habitat Suitability of Pond-Breeding Amphibians Shin-Ruoh Juang 1, Szu-Hung Chen 2 and Chen-Fa Wu 1,* 1 Department of Horticulture, National Chung Hsing University, Taichung City 402, Taiwan; [email protected] 2 Department of Ecosystem Science & Management, Texas A&M University, College Station, TX 77843, USA; [email protected] * Correspondence: [email protected]; Tel./Fax: +886-4-2285-9125 Academic Editor: Iain Gordon Received: 8 November 2016; Accepted: 10 February 2017; Published: 16 February 2017 Abstract: Farm ponds are important habitats for amphibians, birds, and other wildlife. In Taiwan, artificial ponds were originally created on farmlands for irrigation purposes and the needs of the domestic water supply. Although pond creation is a typical farming practice, it also provides habitats for pond-breeding amphibians. Thus, it is essential to understand the current status of habitats and their vulnerability regarding urgent conservation needs for target species. Günther’s frog (Hylarana guentheri), a pond-breeding amphibian, has a high sensitivity towards surrounding environmental changes, and can be used as an indicator species to assess habitat suitability. The purpose of this study is to establish a systematic framework to assess the habitat suitability of pond-breeding amphibians by using Günther’s frog as a pilot-study species. First, we collected frog survey data from Chiayi, Taiwan, from winter 2013 to spring 2015, and investigated the present status of the environmental conditions around the ponds. Next, expert questionnaires and the fuzzy Delphi method were applied to establish the hierarchical evaluation criteria regarding the habitat suitability assessment. -

Currently, there are 13,600 species of pteridophytes around the world, and is the second most dominant plant group. In India, there are 1200 pteridophyte species with 70 families and 192 genera. The pteridophyte hotspots in India are the Himalayas, Western Ghats, Eastern Ghats, Central India, and Andaman and the Nicobar Islands. The Western Ghats occupies only 6% of the Indian landmass and still holds a pteridophyte diversity of 383 species. Fern and fern allies are highly sensitive to changes in their natural habitat, thus habitat ABSTRACT destruction, anthropogenic influences, climate change, etc., are causing a fast decline in their population. Epiphytic species are easily destroyed due to the felling of trees and because of this at present 41- 43% of epiphytic pteridophytes in India are reported to be threatened. It necessitates the frequent analysis of the pteridophyte flora of a region to ensure the existence of its species diversity. The potential of in-vitro and ex-situ conservation techniques can be explored for the conservation of threatened pteridophyte species. -

EVALUATION OF THE EFFECTIVENESS OF THREE SURVEY METHODS FOR SAMPLING TERRESTRIAL HERPETOFAUNA IN SOUTH CHINA 1 YIK-HEI SUNG, NANCY E. KARRAKER, AND BILLY C.H. HAU School of Biological Sciences, The University of Hong Kong, Pokfulam Road, Hong Kong SAR, China 1Corresponding author, email: [email protected] Abstract.—Southeast Asia exhibits high herpetofaunal biodiversity, yet many areas and taxa in the region remain understudied. Extensive surveys are needed to fill information gaps, yet at present we have little knowledge about the effectiveness of different herpetofaunal survey methods in the region. We conducted field studies to examine the effectiveness of three survey methods for sampling terrestrial amphibians and reptiles in Hong Kong. Transect surveys were the most effective at sampling species richness and drift fences with pitfall traps and funnel traps were the most efficient in capturing high numbers of reptiles. We recommend the use of transect surveys for rapid biodiversity assessment and the combination of transect surveys and pitfall traps for comprehensive species inventories. Pitfall traps represent an excellent tool for surveys or population monitoring of leaf litter species. The results of this study will aid researchers in assessing the feasibility of and in choosing herpetofaunal survey methods in Southeast Asia.

A Skeletochronological Estimation of Age Structure in a Population of the Guenther’S Frog, Hylarana Guentheri, from Western China

E-mail: [email protected] [email protected] Submitted on: 2009, 7th August; revised on: 2010, 11th February; accepted on: 2010, 15th April. Abstract. Age determination in amphibians is crucial to investigation of life-history traits. In this context, we studied age structure of the Guenther’s frog, Hylarana guen- theri, population from southwestern China located at an altitude of 300 m using skel- etochronological method. Our results showed that age in adult males ranged from 1 to 4 years, and from 2 to 6 years in adult females. Average age in females was significant- ly older than males in 2008 and 2009. Also, females had significantly larger average body size than males in both years. A significant relationship between age and body size within each sex was found in this species for both years. The ANCOVA analy- sis revealed that there was significant difference in body size between sexes when the effect of age was removed. The von Bertalanffy’s model showed that females had larger asymptotic body size than males, but growth rate of females was smaller than males. Keywords. Skeletochronology, age structure, Hylarana guentheri, sexual size dimor- phism. INTRODUCTION Mark-recapture studies to obtain data on age, growth and longevity of animals are very time-consuming. -

In the past few decades, however, these mangrove forests have been largely degraded and destroyed during the process of development. The negative environmental and socio-economic impacts on mangrove ecosystems have led many government and non- government agencies, together with civil societies, to launch mangrove conservation and rehabilitation programmes, especially during the 1990s. In the course of such activities, programme staff have faced continual difficulties in identifying plant species growing in the field. Despite a wide availability of mangrove guidebooks in Southeast Asia, none of these sufficiently cover species that, though often associated with mangroves, are not confined to this habitat. -
A New Species of Odorrana Inhabiting Complete Darkness in a Karst Cave in Guangxi, China

The new species, Odorrana lipuensis sp. nov., can be distinguished from its congeners by a combination of the following characters: medium size (SVL: 40.7–47.7 mm in males, 51.1–55.4 mm in females); tips of all but first finger expanded with circummarginal grooves; smooth, grass-green dorsum with irregular brown mottling; pineal body invisible; throat to upper abdomen with gray mottling; dorsal surfaces of limbs with brown bands; dorsolateral fold absent; tiny spinules on lateral body, temporal region, and anterior and posterior edge of tympanum; white nuptial pad present on finger I; males lacking vocal sacs; females having creamy yellow eggs, without black poles. Uncorrected sequence divergences between O. lipuensis sp. nov. and all homologous 16S rRNA sequences of Odorrana available on GenBank is equal to or greater than 4.9%. Currently, the new species is only known from the type locality. Keywords Odorrana lipuensis sp. nov., karst cave, Guangxi, southern China 1. Introduction monophyletic group (Chen et al., 2013).

Geographic Distribution and Ecological Function Florida is the only state where the giant leather fern, Acrostichum danaeifolium, is found. It is widely distributed in central and south Florida. It also occurs in Central and South America and in the Caribbean. The giant leather fern grows in coastal hammocks and in brackish and mangrove swamps and further inland along canals and pond edges. It grows vigorously in full sun to full shade but it will not tolerate freezing temperatures. A similar species, the golden leather fern, Acrostichum aureum, is pantropical and has slightly smaller fronds.
