The reef crests of the Jardines de la Reina National Park (JRNP) are largely formed by Acropora palmata, but colonies of A. cervicornis and the hybrid A. prolifera are also present. This study shows spatial distribution of colonies, thickets and live fragments of these species in the fore reefs. Snorkeling was used to perform the direct observations. The maximum diameter of 4,399 colonies of A. palmata was measured and the health of 3,546 colonies was evaluated. The same was done to 168 colonies of A. cervicornis and 104 colonies of A. prolifera. The influence of the location and marine currents on a number of living colonies of A. palmata was analyzed. For such purpose, reef crests were divided into segments of 500 m. The marine park was divided into two sectors: East and West. The Caballones Channel was used as the reference dividing line. The park was also divided into five reserve zones. We counted 7,276 live colonies of Acropora spp. 1.4% was A. prolifera, 3.5% A. cervicornis and 95.1% A. palmata. There were 104 thickets of A. palmata, ranging from eight to 12 colonies, and 3,495 fragments; 0.6% was A. cervicornis and the rest A. palmata (99.4%). In the East sector, 263 colonies (3.8% of the total), six thickets (5.8%) and 32 fragments (1%) of A. palmate were recorded. In the same sector, there were 11 fragments (50%) of A.cervicornis and two (2%) colonies of A. prolifera. Health of A. palmata was evaluated as good and not so good in the study area. Health of A. cervicornis was critical and health of A. prolifera was good in all five reserve zones. There was a significant increase in the number of colonies from east to west (Χ2 = 11.5, gl = 3.0, p = 0.009). This corroborates the existence of an important abundance differences between the eastern and the western region of the JRNP. A negative relationship was observed between the number of colonies and the distance from the channel (Χ2 = 65.0, df = 3.0, p < 0.001). The influence of the channel, for the live colonies of A. palmata is greater within the first 2,000 m. It then decreases until approximately 6,000 m, and no significant increase beyond. The orientation of the reef crests significantly influenced the abundance of the colonies (Χ2 = 15.5, df = 2.9, p = 0.001). The results presented here provide a baseline for future research on the status of the populations of Acropora spp., considering that there has been a certain recovery of the species A. palmata during the last 10–16 years. Given the current status of the populations of Acropora spp., conservation actions focusing A. cervicornis should be prioritized.

Prior to the present study, literature reviews revealed that 31 species of bats belonging to six families and 14 genera were identified in Cat Ba National Park in Northern Vietnam However, the conservation status of many species remains unclear and is still subject to debate. Among the 31 species, 11 are common while the remainder have been rarely captured since 1942. At least two species, Hipposideros alongensis and H. khaokhouayensis, which are globally considered vulnerable, are very common in Cat Ba National Park. This paper provides an update on the current status of each species based on data from recent field surveys with reference to previous publications and the current IUCN Red List (iucnredlist.org). Results from the recent surveys included eight individuals provisionally identified as Myotis cf. pilosus. The taxonomic status of five species (Aselliscus dongbacanus, Hipposideros gentilis, Hipposideros grandis, Miniopterus magnater, Murina harrisoni) are updated following recent assessments. This information will inform future research and conservation actions.

This paper presents a synopsis of the current status and distribution of the African wild dog Lycaon pictus, outlines reasons for its decline and discusses recommendations to halt or reverse this decline. A recent review of the status of the species provides evidence that it has disappeared or is in decline throughout its range (sub-Saharan Africa). Relict populations with little or no chance of long-term survival are found in several countries including Algeria and Senegal. Countries believed to contain potentially viable populations are, from north to south, Kenya, Tanzania, Zambia, Zimbabwe, Botswana, and South Africa (only the Kruger National Park).

The objective of the study was to explore the status of usage of complementary and alternative medicine (CAM) among Korean elite athletes. A survey was emailed to all Korean national sports federations recognized by the International Olympic Committee and the Olympic Council of Asia. A total of 705 Korean elite athletes participated in this study. The athletes had to be any of the following to participate in this survey: elite intercollegiate athletes, professional athletes, and national team athletes. 83.3% of the participants stated that they have previously experienced Korean medicine (KM). Compared to the general population in Korea, athletes had more experience (general population = 73.8%). The participants without experience mentioned that they either did not need any KM treatments (39.8%) or lacked information (39.8%) regarding KM treatments. The primary reason for the utilization of KM was the effectiveness of treatments. Therefore, 70.8% of the participants have mentioned recommending KM to others. Generally, athletes are worrisome that the consumption of herbal medicine may not be doping-free; however, it is vital to note that 62% of the participants expressed that prescribed herbal medicine is safe. Overall, this research demonstrates a high prevalence of KM usage by intercollegiate, professional, and national team athletes in Korea. Hence, this study’s results may serve as the foundation in future research directions for promoting KM among Korean elite athletes.

The ibex Capra pyrenaica has recently recolonized its former Portuguese range from a contiguous Spanish protected area. The first observations of ibex in Portugal were in Peneda-Gerês National Park in 1998. In 2001 we began a survey to confirm ibex presence in Portuguese territory, and to determine the current status of the species there. There are three ibex nuclei in the general area of the international border, and they are expanding their geographical range with two of the nuclei almost restricted to Portuguese territory. In 2003 the ibex population consisted of a minimum of 75 individuals. Different founder histories have led to distinct age structures in each nucleus, but in general they exhibit the population dynamics typical of a recently reintroduced population with high reproductive potential. Priority conservation actions for this newly established population need to include increased monitoring, and reinforcement of the population with individuals from elsewhere. Effective conservation will require collaboration between staff of both Portuguese and Spanish protected areas and an integrated Spanish-Portuguese conservation plan.

The Status

Beginning in 1978, the water level of Jackson Lake, Grand Teton National Park, Wyoming, was lowered first from 2064.5 m (normal pool) to somewhere between 2060-2061 m, and then in 1985 to 2057 m. The purpose of these drawdowns was to facilitate repair and modification of the Jackson Lake dam. In 1989, repair was completed and the reservoir was allowed to fill back to the normal pool elevation of 2065 m. Because of impacts to the littoral habitat in Jackson Lake caused by restoration of the dam at the Snake River outlet, the status of the aquatic plant community was assessed in August, 1989 and 1990. Previous investigations conducted in 1983 (prior to reconstruction) and 1985 (immediately following drawdown to 2055 m) served as a baseline for comparisons. this report summarizes findings from the 1989 and 1990 studies on impacts to the littoral macrophyte community caused by the repair-related drawdowns. To evaluate the current status of the plant community in Jackson Lake, the following objectives were addressed during August, 1990: 1. Re-examine sites sampled in 1989; 2. Examine sites planted during the summers of 1989 and 1990 by the Bureau of Reclamation.

AbstrakTaman Nasional Taka Bonerate (TNT) adalah taman laut dengan kawasan atol terbesar ketiga di dunia setelah Kwajifein di Kepulauan Marshall dan Suvadiva di Kepulauan Maladewa. Luas total dari atol ini 220.000 hektare dengan sebaran terumbu karang mencapai 500 km². Terdapat sekitar 295 jenis ikan karang dan berbagai jenis ikan bernilai ekonomis tinggi seperti Kerapu (Epinephelus spp.), Ikan Naopoleon (Cheilinus undulatus), dan Baronang (Siganus sp). Sebanyak 244 jenis moluska di antaranya Lola (Trochus niloticus), Kerang Kepala Kambing (Cassis cornuta), Triton (Charonia tritonis), Batulaga (Turbo spp.). Penelitian ini bertujuan memberikan perlindungan hukum terhadap ekosistem terumbu karang di TNT. Metode peneltian bersifat normatif-kuantitatif. Penelitian ini menunjukan bahwa status sebagai Taman Nasional belum memberikan perlindungan hukum yang kuat terhadap Taka Bonerate. Diperlukan payung hukum yang lebih konkrit untuk melindungi ekosistem terumbu karangnya. AbstractTaka Bonerate National Park is a marine park with the region’s third largest atoll in the world after Kwajifein Suvadiva in the Marshall Islands and the Maldives Islands. The total area of the atoll is 220,000 hectares with coral reefs spreading up to 500 km². There are about 295 species of reef fish and various types of high-value fish such as grouper (Epinephelus spp.), Napoleon fish (Cheilinus undulatus), and Baronang (Siganus sp). A total of 244 species of molluscs in between Lola (Trochus niloticus), Shells Goats Head (Cassis cornuta), Triton (Charonia tritonis), Batulaga (Turbo spp.). This study aims at providing legal protection for biodiversity in the National Park Takabonerate. Other research methods are normativequantitative. This study shows that the status as a national park not provide strong legal protection against Takabonerate. Required more concrete legal basis for protecting biodiversity.
