The Antillean manatee, Trichechus manatus manatus, is among the most threatened mammals in Honduras, yet the last published study is from 1980. Since then, the North Coast of Honduras has experienced rapid population growth and land cover change possibly causing habitat loss for manatees. We conducted aerial, boat, and interview surveys between 2005-2007 along the northern and remote eastern coasts of Honduras to assess the current status and distribution of manatees. In addition, we compiled all available data on manatee mortality from museum specimens, unpublished reports, and interviews to determine current threats. We averaged 1.2 manatee sightings per survey hour during six flights along the North Coast in March-April 2006 during 14.4 aerial survey hours. Sightings were mainly clustered in Cuero y Salado Wildlife Refuge (CSWR) and Rios Chapagua and Aguan, which we indentify as important conservation areas. Our total and average sightings per survey hour in CSWR were much lower than those reported in 1979-80, in spite of the area being protected since 1987. Our interviews indicate that manatees are still present on the eastern coast (La Mosquitia), however we observed none during 14.5 survey hours in June 2005 and April 2007. The major cause of known mortality from 1970-2007, based on 26 records, was due to entanglement in fishnets. Despite local and federal protection, manatees are still poached and opportunistically caught in fishnets. While some efforts have been made by local NGOs to raise public awareness for manatees, a national conservation program is highly recommended to centralize and coordinate efforts.

Currently, little is known about the helminth fauna in sirenian species. Therefore, the objective of this study was to assess the frequency of infection by Pulmonicola cochleotrema in Antillean manatees (Trichechus manatus manatus), in the North-eastern region of Brazil. Between the years of 1989 and 2014, 88 manatees found on the North-eastern Brazilian coast were clinically examined. They included animals that were found dead, animals maintained in captivity and specimens reintroduced into conservation areas. During their physical examination, helminths present in necropsied carcasses and in reintroduced animals were collected, as well as faecal samples. Parasites were detected in 7.95% (7/88) of the animals; all specimens collected being identified as P. cochleotrema. Only adult manatees were infected, and in two cases clinical signs were observed. This is the first report on the occurrence of P. cochleotrema in Antillean manatees in the states of Paraíba and Sergipe, in the North-eastern coast of Brazil.

Background Qatar is located on the north-eastern coast of the Arabian Peninsula. Qatari natives account for less than 15% of the population while the largest migrant group comprising 60% derives from South Asia. Despite projections that stroke burden in Qatar will increase with population ageing, epidemiological studies focusing on stroke in Qatar are relatively scarce. Method We reviewed the available epidemiological publications relating to Qatar. In addition, we have added to this knowledge by incorporating Qatari data from the on-going Bio-Repository of DNA in Stroke, an independent multinational database of stroke patients. Results Qatar has low reported incidence and mortality rates of 58 and 9.17 per 100,000 per year, respectively, which may be explained by its middle-aged migrant worker majority population. Correspondingly, South Asian migrants in Qatar suffered younger strokes than Qatari natives (48.7 vs 63.4 years, P < 0.001). Among the most common risk factors identified in stroke patients were hypertension (77.9%), diabetes (43.8%) and hypercholesterolemia (28.5%). Ischaemic stroke was the most frequent subtype amongst migrant South Asians (71.1%). The majority of stroke cases had computed tomography and/or magnetic resonance imaging scans, but only 11.1% of ischaemic strokes were thrombolysed. Qataris on one-year follow up were more often found to have died (6.5% vs 0.3%) and had further stroke/transient ischaemic attack events (17.4% vs 6.4%, P = 0.009) compared to South Asians. Conclusion The burden of stroke is increasing in Qatar, and considerable disparities are observed between the native and migrant populations which likely will require different approaches to management by its healthcare system.

A New Species

A new species, Eucalyptus fusiformis Boland et Kleinig, from the north coast of New South Wales is described. Its taxonomic position is in E. subgenus Symphyomyrtus series Paniculatae following the informal classification of eucalypts proposed by Pryor and Johnson (1971). E. fusiformis is characterised by its flowers, fruits and adult leaves. In the bud the staminal filaments are fully inflected while the androecium has outer staminodes and the anthers are cuboid and adnate. The fruits are narrow, often truncate fusiform, tapering into long slender pedicels. The adult leaves are dull grey, concolorous and hypoamphistomatic. The species resembles the more numerous and often co-occurring ironbark E. siderophloia which has similar adult and seedling leaves. The volatile oils of both species are very similar. The ecology, distribution, taxonomic affinities and conservation status are discussed.

A região contém o maior numero de unidades de conservação do estado da Paraíba. O aumento da visitação turística torna necessário o planejamento turístico sustentável da região. No contexto ecológico, a hotelaria deve prestar serviços com impacto ambiental reduzido para promover o desenvolvimento local sustentável. O presente estudo pretende observar a gestão da hotelaria do litoral norte da Paraíba sob o paradigma da sustentabilidade. Através de pesquisa qualitativa, os gestores responsáveis pelo serviço de hotelaria foram entrevistados. A gestão da hotelaria do litoral norte da Paraíba atua de modo inadequado às premissas do desenvolvimento sustentável. O contexto local demanda planejamento turismo ecológico para evitar a desestruturação da natureza e da cultura tradicional. Sustainable management: evaluation of socio-environmental responsibility in the lodging facilities of the northern coast of Paraíba (Brazil) ABSTRACT The northern coast of Paraiba presents a singular context that includes Baroque architecture, indigenous presence and the sanctuary of Manatees (Trichechus manatus).The region contains the largest number of conservation units in the state of Paraiba. The increase in tourist visitation makes the region's sustainable tourist planning necessary. In the ecological context, the hospitality industry must provide services with reduced environmental impact to promote sustainable local development. This study aims to observe the management of the hospitality of the north coast of Paraiba under the sustainability paradigm. Through qualitative research the managers responsible for the hospitality service were interviewed. The management of the hospitality of the north coast of Paraiba acts inappropriately to the premises of sustainable development. The local context demands ecological tourism planning to avoid the destructuring of nature and traditional culture. KEYWORDS: Hospitality Industry; Sustainable Management; Ecological Tourism.

New Evidence

AbstractThe geographical distribution of the Ananatuba phase has been extended to the eastern coast of Marajó by the discovery of J-26: Castanheira on the right bank of the middle Rio Camará. Two stratigraphic cuts were excavated, and the pottery obtained was classified into the types established by Meggers and Evans (1957). The resulting seriated sequence shows trends of ceramic change parallel to theirs and a similar intrusion of Mangueiras phase sherds in the upper levels of the deposit. Interdigitation of the J-26 levels into the seriated sequence for the Ananatuba phase shows the new site to occupy a relatively late position, supporting the earlier inference of expansion from the north coast toward the southeast during the history of the phase. A charcoal sample obtained from Cut 1, Level 40-50 cm., and correlating with the appearance of Mangueiras phase sherds in the refuse, gave the date of 980 B.C. ± 200 (SI-385), which places the initial occupation of Marajó by pottery-making groups within the Formative period.

SummaryThe Balearic Shearwater Puffinus mauretanicus is considered one of the most threatened seabirds in the world, with the breeding population thought to be in the range of 2,000–3,200 breeding pairs, from which global population has been inferred as 10,000 to 15,000 birds. To test whether the actual population of Balearic Shearwaters is larger than presently thought, we analysed the data from four land-based census campaigns of Balearic Shearwater post-breeding migration through the Strait of Gibraltar (mid-May to mid-July 2007–2010). The raw results of the counts, covering from 37% to 67% of the daylight time throughout the migratory period, all revealed figures in excess of 12,000 birds, and went up to almost 18,000 in two years. Generalised Additive Models were used to estimate the numbers of birds passing during the time periods in which counts were not undertaken (count gaps), and their associated error. The addition of both counted and estimated birds reveals figures of between 23,780 and 26,535 Balearic Shearwaters migrating along the north coast of the Strait of Gibraltar in each of the four years of our study. The effects of several sources of bias suggest a slight potential underestimation in our results. These figures reveal the urgent need to reformulate the population viability analysis for the species, and then if necessary reconsider its conservation status.

Sri Lanka is a country with unique landscapes and positioning. Its land profile varies from coastal areas through lowland hills to central montane region, and the climatic zones governed by seasonal monsoons results in a significantly high biodiversity.         Sri Lanka together with Western Ghats is a biodiversity hot spot among the 35 regions known worldwide. Sri Lanka harbors 3154 species of which 894 are endemics belonging to different angiosperm families. The orchid flora of the country, with 189 known species including 55 endemics is one that contributes very much for this high endemism. However 70.6% are currently listed as nationally threatened species during National Red listing in 2012.         The present study was conducted to investigate the current status and occurrence of species of the family Orchidaceae within and outside the conservation areas including few unexplored/ undocumented regions in the country. Field visits were carried out mainly focusing on the flowering seasons. Fourteen different sites including Forest Reserves, Sanctuaries, Strict Nature Reserves and Wildlife Parks were taken into consideration during this study. Observations were made in the field and locations recorded, collected data were tabulated and compared with available information. The observation made during the present study would make a large contribution for updating the conservation status of orchids at national and global level red listing.

SummaryPeruvian Terns Sternula lorata breed in the sand desert plains of the coast of Perú and northern Chile. Because of their long-term population decline, Peruvian Tern is categorized as ‘Endangered’ on the IUCN Red List. The observations that formed the basis for that decision were made in the 1970s and 1990s. In this study, we compile information on distribution, numbers, habitat use and threats of Peruvian Terns that has become available between 2003 and 2008 from 14 localities on the Peruvian coast. Peruvian Tern sites are located between the mangroves of San Pedro de Vice in the north (5o31’S) and the wetlands of Ite in the south (17o56’S). From the 14 locations, five are reported for first time: Virrilá, Eten, Huanchaco, isla Mazorca and Ite. There were only four active breeding sites: Pacasmayo, Paraíso, Pampa Lechuzas and Tres Hermanas-Yanyarina; however, some localities were visited outside the breeding season and should be surveyed between October and February to search for nests. The presence of 283 individuals was confirmed at the 14 sites in an area of approximately 1,388 ha (which represents only 0.35% of the total suitable area for nesting along the Peruvian coast). Thus, the number of Peruvian Terns in Perú should increase with systematic surveys. Here for the first time we report the importance of wetlands for the Peruvian Terns (43% of the sightings occurred in this habitat). Wetlands can offer optimal conditions for feeding, but the cost of using them is becoming higher with a sharp increase of human expansion into coastal areas and urban development around wetlands. We identified the following threats affecting Peruvian Terns on their feeding and breeding grounds: 1) recreational activities; 2) off-road driving by fishermen and tourists; 3) wetland pollution and water use for irrigation; 4) conversion of desert plains to agricultural land; 5) management of wetland water levels; 6) presence of feral cats and dogs, and 7) oil exploration on the desert plains. These adverse factors can be eradicated by the protection of tern sites and public awareness and education. Conservation actions, monitoring and research priorities are suggested.

Common Dolphins

The north-eastern coast of Venezuela hosts a high diversity of megafauna, particularly related with high productivity due to coastal upwelling. This area is mainly characterized by the existence of the primary fisheries in Venezuela, mostly supported by a great abundance of small pelagic species. This would explain why the area supports a wide range of marine top predators, including cetaceans. The current status of cetacean populations off north-eastern Venezuela is uncertain, mainly because research efforts have been very sparse. There are still many gaps of information in cetacean biology to establish a solid baseline that can be used for management decisions. Common dolphins (Delphinus spp.) are widely dispersed over the whole north-east basin, including waters off Araya and Paria Peninsula and around Margarita, Coche and Cubagua Islands. Areas of higher densities for Delphinus spp. coincide with the focal location of sardine fisheries and the most-active upwelling on the north-eastern coast. Therefore, a scheme of management should consider the areas of major productivity along the coast as potential critical habitat for the species. Further data collection is recommended, increasing aspects such as trophic ecology and the continuity of behavioural sampling, paired with systematic line transect estimation.
