Tonga is one of the many islands that are endowed with unique resources and derives much of its economic, environmental and social well-being directly or indirectly from its environment. Tonga harbours numerous special ecosystems: from the peak of Mt, Talau in Vava’u, to the serenity of Vai Lahi in Niuafo’ou; the vulnerability of the Ha’apai Group to ‘Eua’s National Forest and to the Fanga’uta Lagoon in Tongatapu. Beyond the aesthetic beauty of the ecosystems to tourists and visitors; they provide immense support to the communities whose livelihoods are centred. They provide food, shelter, fresh water, wood, fibre, medicine, fuel, tools and raw materials. They also provide spiritual, recreational values, educational references as well as contributing to the economies, livelihoods and culture of Tonga. Our ecosystems maintain and provide protection against diseases, climate, natural disasters, support nutrients cycling, and aid sand and soil formation. Ecosystems and their biodiversity underpin sustainable development and human wellbeing. The loss of biodiversity results in serious reductions in ecosystem goods and services, negatively impacting economic prosperity and social and environmental sustainability. Therefore, there is a need to invest and re-invest in the productivity, health and sustainability of our ecosystems. The well-being of the world population in the coming decades will at large depend on conservation and restoration of ecosystems to maintain and enhance biodiversity and ecosystem services, thereby contributing to sustainable development while reducing economic, social and environment related risks. Objectives: The objectives of this report are to: 1. Update on biodiversity status, trends, and threats and implications for human well-being 2. Identify the current status of national biodiversity strategy and action plan, its implementation, and the mainstreaming of biodiversity 3. Discuss the Progress towards the 2020 Aichi Biodiversity Targets and contributions to the relevant 2015 Targets of the Millennium Development Goal. Page | 3 Tonga’s Fifth Review Report on the National Biodiversity Strategy and Action Plan 2014 An ecological, socio-economic survey was conducted to review the National Biodiversity Strategic Action Plan (NBSAP) and to develop the 5th National report. A series of community consultations in Tongatapu, ‘Eua, Vava’u, Ha’apai, Niuatoputapu and Niuafo’ou islands groups were conducted. There were also literature and desk review, field observations and in depth interviews with various stakeholders. Chapter 1 based its discussions on the updating of the biodiversity status, trends, threats and implications on human wellbeing. This includes forest, agro-biodiversity, marine ecosystems and species conservation. Forest ecosystem The current status of biodiversity has raised some questions with regards to the validity of the five species included in the IUCN Red List of 2009. Of the five species submitted, only Aglaia heterotricha (langakali vao) is supported and therefore should be maintained in the list. The other species recommended for inclusion include Casearia bluelowii and Sesbania coccinea. Target species identified for conservation should have regulatory protection and should be enforced by the law. Annual ban should be imposed on harvesting and trading of specific species that are either endemic or near extinction. Land use policy, plans and strategies are thoroughly considered for the protection and conservation of forest ecosystems and to address its multipurpose potentials. The lack of and/or absence of management plans for the conservation and protection of endemic species continue to pose major threat. Moreover the uncontrolled and illegal harvesting, as well as, encroachment was identified as common threats to biodiversity conservation in Tonga. People’s attitudes and behaviour may also attribute to biodiversity conservation threats. Commercial farming has also been identified as a major threat to forest ecosystem conservation. Increased number of invasive species continues to threaten our traditional genetic resources. Agrobiodiversity There is a reduction in variety of traditional crop species as you move further north from Tongatapu. This is due to the islands smallness and remoteness from Tongatapu. The variety of fruit trees are also decreased due to increase competition for land use, especially for commercial farming and population increase. Page | 4 Tonga’s Fifth Review Report on the National Biodiversity Strategy and Action Plan 2014 Other threats identified include heavy dependency on machinery for cultivation, fertilisers and pesticides, and climate change and natural disasters. Urban Spatial Management Act of 2012 and the National Land Use Policy could both attribute to a more comprehensive land use management. Tonga’s limited genetic pool may lead to loss of traditional genetic materials that may have been endemic to Tonga. This could explain the poor diversity in our root crop species (tuber- base cultivars) in comparison to fruit trees (seed based cultivars). Marine ecosystems The demand for marine resources has increased due to Tonga’s growing population and change in dietary demands. Overexploitation and destructive fishing practices are still the major threats to the marine ecosystem although natural disasters (i.e. hurricanes & tsunamis, water temperatures variations, natural predators, etc.) may contribute. The destructive fishing methods such as dynamite fishing, fish poisoning and using hookah and SCUBA diving are still ongoing activities even though regulatory wise, these fishing methods has been declared illegal practices under Fisheries Management Act 2002. The SCUBA and hookah under water using air apparatus boasted as other major threats for the reef fishes and sea cucumbers resources included giant clams’ species (i.e. Tridacnidae). Pollution and eutrophication also affect Tonga’s coastal waters and reefs (Anon, 2010). The trend of the marine biodiversity is still unknown. The only baseline information might assist in determining the change in the marine ecosystem (refer to tables & figures indicated on chapter 1 of marines thematic area) is the landing catch and export production recorded by Fisheries Division database for the major commercial marine resources at Tongan coastal waters during this period (2010 – 2013). Species Conservation The fourth National report articulated the success of species conservation could be contributed to the involvement of private sector and civil society. This fifth national report has seen another stunning success, more donors are funding projects related to species conservation. For example, Tonga is a participant in two significant multi-country projects, supported by the Global Environment Facility (GEF), that are focused on the conservation of biodiversity and the management of major threats that cause biodiversity loss. The two projects are both under the Page | 5 Tonga’s Fifth Review Report on the National Biodiversity Strategy and Action Plan 2014 auspices of the Pacific Alliance for Sustainability housed under the South Pacific Regional Environmental Programme (PAS-SPREP) The GEF-PAS (GEF –Pacific Alliance for Sustainability) Island Biodiversity Project titled ‘Implementing the Island Biodiversity Programme of Work by integrating the conservation management of island biodiversity’ and the GEF-PAS Pacific Invasive Project. There are more regulatory framework are drafted and passed, more flexible working environment are provided for government ministry to operate in- to ease implementation and execution of duties in relation to species conservation. To date, 13 more Special Management Areas were added to 13 protected areas of 2010, 12 organically certified sites and in situ and ex situ based projects have been funded for terrestrial and marine based organisms. There is also a major boost in the amount of donor funded projects that are involved in species and resource conservation thus giving Tonga a lot of prospect for becoming a major conservation hub in the region. There is also a collective effort to put into place regulatory framework that could govern conservation effort. Collaboration and partnerships between donors, government ministries and those of the civil societies has also been instrumental in this success. Chapter 2 deals with National biodiversity strategy and action plan, its implementation and the mainstreaming of biodiversity. The reviewing of the implementation

  • Predator Defense Mechanisms in Shallow Water Sea Cucumbers (Holothuroidea)
    PREDATOR DEFENSE MECHANISMS IN SHALLOW WATER SEA CUCUMBERS (HOLOTHUROIDEA) JESSICA A. CASTILLO Environmental Science Policy and Management, University of California, Berkeley, California 94720 USA Abstract. The various predator defense mechanisms possessed by shallow water sea cucumbers were surveyed in twelve different species and morphs. While many defense mechanisms such as the presence of Cuverian tubules, toxic secretions, and unpalatability have been identified in holothurians, I hypothesized that the possession of these traits as well as the degree to which they are utilized varies from species to species. The observed defense mechanisms were compared against a previously-derived phylogeny of the sea cucumbers of Moorea. Furthermore, I hypothesized that while the presence of such structures is most likely a result of the species’ placement on a phylogenetic tree, the degree to which they utilize such structures and their physical behavior are influenced by their individual ecologies. The presence of a red liquid secretion was restricted to individuals of the genus Holothuria (Linnaeus 1767) however not all members of the genus exhibited this trait. With the exception of H. leucospilota, which possessed both Cuverian tubules and a red secretion, Cuverian tubules were observed in members of the genus Bohadschia (Ostergren 1896). In accordance with the hypothesis, both the phylogenetics and individual ecology appear to influence predator defense mechanisms. However, even closely related species of similar ecology may differ considerably. Key words: holothurians; defense; toxicity; Cuverian tubules; Moorea, French Polynesia INTRODUCTION (Sakthivel et. Al, 1994). Approximately 20 species in two families and five genera, Sea cucumbers belong to the phylum including Holothuria, Bohadschia, and Thenelota, Echinodermata and the class Holothuroidea.

A recent molecular study showed that the putative variety Holothuria (Metriatyla) scabra var. versicolor Conand, 1986 (‘golden sandfish’) is a distinct species from, but could hybridize with, H. (Metriatyla) scabra Jaeger, 1833 (’sandfish’). Examination of the skeletal elements and external morphology of these species corroborates these findings. The identity of H. (M.) scabra is unambiguously defined through the erection and description of a neotype, and several synonyms have been critically re-examined. The nomenclaturally rejected taxon H. (Metriatyla) timama Lesson, 1830 and H. (M.) scabra var. versicolor (a nomen nudum) are herein recognized as conspecific and are allocated to a new species, Holothuria lessoni sp. nov., for which type specimens are described. The holotype and only known specimen of H. aculeata Semper, 1867, has been found and is redescribed.

  • Community Structure, Diversity, and Distribution Patterns of Sea Cucumber
    Community structure, diversity, and distribution patterns of sea cucumber (Holothuroidea) in the coral reef area of Sapeken Islands, Sumenep Regency, Indonesia 1Abdulkadir Rahardjanto, 2Husamah, 2Samsun Hadi, 1Ainur Rofieq, 2Poncojari Wahyono 1 Biology Education, Postgraduate Directorate, Universitas Muhammadiyah Malang, Malang, East Java, Indonesia; 2 Biology Education, Faculty of Teacher Training and Education, Universitas Muhammadiyah Malang, Malang, Indonesia. Corresponding author: A. Rahardjanto, [email protected] Abstract. Sea cucumbers (Holothuroidea) are one of the high value marine products, with populations under very critical condition due to over exploitation. Data and information related to the condition of sea cucumber communities, especially in remote islands, like the Sapeken Islands, Sumenep Regency, East Java, Indonesia, is still very limited. This study aimed to determine the species, community structure (density, frequency, and important value index), species diversity index, and distribution patterns of sea cucumbers found in the reef area of Sapeken Islands, using a quantitative descriptive study. This research was conducted in low tide during the day using the quadratic transect method. Data was collected by making direct observations of the population under investigation. The results showed that sea cucumbers belonged to 11 species, from 2 orders: Aspidochirotida, with the species Holothuria hilla, Holothuria fuscopunctata, Holothuria impatiens, Holothuria leucospilota, Holothuria scabra, Stichopus horrens, Stichopus variegates, Actinopyga lecanora, and Actinopyga mauritiana and order Apodida, with the species Synapta maculata and Euapta godeffroyi. The density ranged from 0.162 to 1.37 ind m-2, and the relative density was between 0.035 and 0.292 ind m-2. The highest density was found for H. hilla and the lowest for S.

E-mail: [email protected] 2 BIOGES, Universidad de Las Palmas de Gran Canaria, 35017, Las Palmas de G.C., Spain. SUMMARY: The reproductive biology of the sea cucumber Holothuria sanctori was studied over 24 months (February 2009 to January 2011) at Gran Canaria through the gonad index and a combination of macro- and microscopic analysis of the gonads. Holothuria sanctori showed a 1:1 sex ratio and a seasonal reproductive cycle with a summer spawning: the mean gonad index showed a maximum (3.99±0.02) in summer (June-July) and a minimum (0.05±0.04) between late autumn (November) and early spring (March). Females had significantly wider gonad tubules than males. First maturity occurred at a size of 201 to 210 mm, a gutted body weight of 101 to 110 g and a total weight of 176 to 200 g. Holothuria sanctori shows a typical temperate species reproduction pattern. These results could be useful for managing current extractions of H. sanctori in the Mediterranean and in case a specific fishery is started in the eastern Atlantic region.

Rahimibashar Department of Marine Biology, Lahijan branch .Islamic Azad University Lahijan, Iran ABSTRACT As each new species evolved, the ossicles changed with it, so each species has uniquely shaped ossicles. Examination of gross morphology and microscopic ossicles showed that this species is Holothoria atra. Color uniformly black or dark brown; when alive body usually covered with sand coating of sand which may also serve to keep it cool by protecting it from the sun's rays. , except for several pairs bare patches dorsally; tables with reduced but sometimes spinose disc. The importance of detailed reproductive biological studies on Holothuria atra are necessary due to its important role in the conservation of the marine environment. This species found on subtidal sand and grassbed, 3to 4 m depth at Kish Island. Distributed throughout most of the tropical Indo-Pacific area. Holothoria atra, is a holothurian of order Aspidochirotes belonging to the family Holothuriidae genus Holothuria. It is deposit-feeder and is mainly found on sandy bottom of fringing reefs surrounding the Kish island. Holothoria atra, is a holothurian of order Aspidochirotes belonging to the family Holothuriidae genus Holothuria. Holothuria atra is an omnivore, sifting through the sediment with its tentacles and feeding on detritus and other organic matter. It ingests sand at the same time and digests the biofilm on the sand grains before ejecting them through its anus.
