The genus Odorrana currently contains at least 56 recognized species that inhabits montane streams in subtropical and tropical Asia. Twenty new species have been described in the last decade, indicating the potential cryptic species diversity of this genus. We collected several specimens of Odorrana species from Southern China from 2007 to 2014, and on the basis of a combined morphological characters and phylogenetic analysis, we described the new species Odorrana fengkaiensis sp. nov. herein. The new species is very similar to O. hainanensis and O. bacboensis, but can be consistently separated by morphology, and allopatric distribution. It is further reciprocally monophyletic to O. hainanensis in a mitochondrial gene trees with an average genetic divergence of 2.1% (1.9%-2.4%). The new species inhabits in lowland broad streams, rivers, pools and near the riparian areas, but its general ecology remains poorly known. The new species is characterized by its body length of adult females approximately twice as long as adult males (SVL 77.8-111.9 mm in females, 37.4-51.8 mm in males); eye large in males, eye diameter 1.01-1.16 times as long as snout length; tympanum of males large and distinct, extremely close to the eye, 0.7-1.4 mm in tympanum-eye distance; dorsolateral folds absent; dorsal skin shagreened, with several large tubercles in males; flanks with tubercles and scattered larger pustules, 8-10 of which usually arranged in a dorsolateral row; ventral skin smooth, with spines in adult males during the breeding season; the tibio-tarsal articulation stretched forward beyond the tip of snout; relative finger lengths: II < I < IV < III; dorsum brown with irregularly reticulated green markings in males and young females, uniformly brown in some old adult females; males with velvety nuptial pad on thumb, paired gular pouches; mature oocytes almost purely black in life, showed dark grey animal pole and olive vegetative pole in preservative. In addition, we found O. bacboensis, a new country record from China, indicating a range extension from north-central Vietnam to southeast Yunnan and adjacent area in Guangxi.

Although China has long been considered as the "World's Manufacturer Centre", she has always been criticized that her manufacturing process has resulted in significant damages to the environment. Many manufacturers have attempted to implement green manufacturing initiatives; however, they are lacking in experience or technology to successfully achieve their goals or targets. This paper analyses the challenges and opportunities in adopting green manufacturing initiatives using a case study approach. Semi-structured interviews are performed in 4 sizeable and reputable garment manufacturers in Hong Kong and China. External stakeholders who significantly affect the green manufacturing initiatives are interviewed. They include brands (customers), consultants, NGOs and government agents. Based on the data collected, the external stakeholders actually play multiple roles and may interact with each other in the process of adopting green initiatives. The four manufacturers in this study have different leadership styles, market shares, operation cultures and marketing strategies. However, the different successful paths in overcoming the adaptability challenges have been identified. This paper intends to provide alternative successful paths for other manufacturers to follow in adapting to green initiatives that are becoming a growing concern across all manufacturing industries. © 2012 CIE & SAIIE.

An unidentified small frog species was first encountered in Hong Kong Special Administration Region (SAR), China, in 2000, where the local amphibian diversity is well-studied. We herein identified this unknown frog as Eleutherodactylus planirostris (greenhouse frog) using DNA barcoding. We found that its distribution in Hong Kong is widespread (>18 localities), and breeding has been observed in multiple occasions. The populations in at least four localities persisted for over seven years. We discuss its potential negative impacts to terrestrial ecosystems in Hong Kong, with particular concern of its potential competition with the endemic Liuixalus romeri. We call for studies to investigate the impacts of the introduced E. planirostris on the local ecosystem. Screening for E. planirostris in exported plants from Hong Kong should be carried out. © Firenze University Press. Source

Fish and Fisheries | Year: 2013

Groupers are a valuable fishery resource of reef ecosystems and are among those species most vulnerable to fishing pressure because of life history characteristics including longevity, late sexual maturation and aggregation spawning. Despite their economic importance, few grouper fisheries are regularly monitored or managed at the species level, and many are reported to be undergoing declines. To identify major threats to groupers, the International Union for Conservation of Nature (IUCN) Red List criteria were applied to all 163 species. Red List assessments show that 20 species (12%) risk extinction if current trends continue, and an additional 22 species (13%) are considered to be Near Threatened. The Caribbean Sea, coastal Brazil and Southeast Asia contain a disproportionate number of Threatened species, while numerous poorly documented and Near Threatened species occur in many regions. In all, 30% of all species are considered to be Data Deficient. Given that the major threat is overfishing, accompanied by a general absence and/or poor application of fishery management, the prognosis for restoration and successful conservation of Threatened species is poor. We believe that few refuges remain for recovery and that key biological processes (e.g. spawning aggregations) continue to be compromised by uncontrolled fishing. Mariculture, through hatchery-rearing, increases production of a few species and contributes to satisfying high market demand, but many such operations depend heavily on wild-caught juveniles with resultant growth and recruitment overfishing. Better management of fishing and other conservation efforts are urgently needed, and we provide examples of possible actions and constraints. © 2012 Blackwell Publishing Ltd. Source

Lack of cooperation between nations which have competing claims to the sea is also contributing to the depletion, they said. A number of countries claim the waters, including their reefs and rocky outcrops. A study shows the number of some species at about five percent of 1950s levels. Several of them, such as coral groupers and Napoleon Wrasse, have declined by 80 percent in the past eight years alone, it said. "The South China Sea is... under threat from various sources. We need to do something," said Rashid Sumaila, director of the Fisheries Economics Research Unit of the University of British Columbia. "The most scary thing is the level of decline we have seen over the years. Some species (are facing) technically extinction or depletion," Sumaila, who headed the study, told a press conference in Hong Kong. Sumaila said political disputes were also damaging fish stocks. China claims sovereignty over almost all the South China Sea, but Vietnam, Malaysia, the Philippines, Taiwan and Brunei have competing claims in some areas. "There are lots of peoples bordering the South China Sea... when you don't cooperate, everybody races for the fish because the thinking is if you don't catch the fish someone else (from another country) will catch it," Sumaila said. WWF Hong Kong said earlier this year a growing appetite for seafood was threatening surrounding waters, as a study showed more than half the species available in the city's restaurant tanks were from "highly unsustainable" sources.
