<p>The stable microclimate in caves provides a relatively constant habitat for many bat species in the Philippines, but human encroachment continues to disrupt this habitat and imperil many of the species roosting in the caves.  In South central Mindanao, the diversity and conservation status of cave bats remain undocumented and unexplored.  We employed mist-netting to capture bats from five different caves within the town of Kabacan, northern Cotabato, Philippines.  A total of 14 bat species were identified including the Philippine endemics <em>Hipposideros pygmaeus </em>and <em>Ptenochirus jagori </em>and the threatened <em>Megaerops wetmorei. </em>However, despite the declining conservation status of the bats, local disturbance such as bat hunting for bush meat and unregulated tourism are currently taking place in the caves.  Large species such as <em>Eonycteris spelaea </em>and <em>Rousettus amplexicaudatus </em>are killed almost every day for food and trade.  Therefore, the high species richness, and the presence of endemic and threatened species coupled with the occurrence of anthropogenic disturbances in caves suggests the need for an urgent and effective conservation intervention involving the local government and public community.</p><div> </div>

Anthropogenic environmental changes coupled with rapid population growth are altering the Earth’s biota at an unprecedented rate, posing an alarming threat to the long-term persistence of many species of both animals and plants. The Philippine archipelago includes over 7000 islands, and of its diverse mammalian biota bats make up a significant proportion, and fulfil vital roles to maintain ecosystem health. Given the high species richness, endemism, vulnerability, and disparity in efforts, the Philippines is a conservation priority for bats. In this study, we aim to determine the vulnerability of Philippine bat species from different threats in order to establish effective conservation decision making and prioritisation in the future. Habitat loss and direct human-driven factors (e.g., hunting) are the main threats to more than half of Philippine bat species. We found that body size and number of threats are important correlates of species vulnerability. While there is no correlation in neither threat levels nor body size with research effort and allocation. We suggest that priorities should consider multiple facets of knowledge gaps, levels of threats and species vulnerability for effective conservation. Carefully looking at the emerging threats, increasing conservation education, and forging equitable partnerships and capacity building to bolster bat conservation in the Philippines.

Acacia s.l. farnesiana , which originates from Mesoamerica, is the most widely distributed Acacia s.l. species across the tropics. It is assumed that the plant was transferred across the Atlantic to southern Europe by Spanish explorers, and then spread across the Old World tropics through a combination of chance long-distance and human-mediated dispersal. Our study uses genetic analysis and information from historical sources to test the relative roles of chance and human-mediated dispersal in its distribution. The results confirm the Mesoamerican origins of the plant and show three patterns of human-mediated dispersal. Samples from Spain showed greater genetic diversity than those from other Old World tropics, suggesting more instances of transatlantic introductions from the Americas to that country than to other parts of Africa and Asia. Individuals from the Philippines matched a population from South Central Mexico and were likely to have been direct, trans-Pacific introductions. Australian samples were genetically unique, indicating that the arrival of the species in the continent was independent of these European colonial activities. This suggests the possibility of pre-European human-mediated dispersal across the Pacific Ocean. These significant findings raise new questions for biogeographic studies that assume chance or transoceanic dispersal for disjunct plant distributions.

Today’s climate is unpredictable there are so many natural calamities which took place in our country which is the Philippines, two weeks ago because of the sudden changes of the weather in the Province of Zambales, the Philippines a strong tornado hits the town of Castillejos, Zambales which some of the electrical wirings were severely damaged because of the sudden change of the climate. The researcher is thinking of implementing a home gardening to each Municipality in our Province. By doing this it can help lessen the pollution in the air and it will help heal our Ozone Layer faster. The empirical evidence for the benefits of gardening and the advocate of the development and testing of socio-ecological models of community resilience through the impact of community gardens, especially in urban areas is highly effective(Okvat & Zautra, 2011). As lessening the air pollution will have a greater impact on our Ozone Layer no to deplete but it will heal the would faster. The present study revealed that local experiences in the face of climate change adaptation have merits that need special consideration(Anik & Khan, 2012). Also, the Researcher will implement this project in the Municipality of Subic, Zambales.

The number of police in the Philippines is way below than the declared number of police per population based on the Philippines Republic Act No. 6975, Chapter 3, Section 27 which states that one (1) policeman per five hundred (500) persons. Santa Maria Bulacan only have fifty-two (52) police personnel, and one (1) police outpost which is located in the town of Poblacion which is in the far south east of the whole municipality. This produces different speed when responding to incident reports. The police force’s response time vary based from the location of the incident. This research determined the optimum location to where police will be deployed as a mobile unit to be able to respond faster to more areas than staying in the outpost. Another thing that will be determined by this research is the optimum coordinates of a perfect scenario where each town in the municipality of Santa Maria Bulacan would have their own police outpost. The coordinates will be calculated based on the populations’ location by plotting all the houses and structures located in Santa Maria Bulacan based on Google Map Images, and the Optimum locations will be determined in the form of the converged centroids after applying enhanced K means clustering algorithm.

A new slender clustering palm, Heterospathe fernandoi, from forests on ultramafic soils in Samar, Dinagat, Bucas Grande, and northeastern Mindanao in the Philippines is described and illustrated. It is similar to H. scitula in its general vegetative and reproductive characters but differs in its somewhat persistent leaf sheaths, relatively wider median unicostulate leaflets, and interfoliar inflorescences in which both the axes and perianth are typically coloured light purple to deep maroon during anthesis. Its morphology, habitat, ecology, and conservation status are also discussed.

Freshwater ecosystems (including inland saline wetlands and mound springs) are among the more imperilled ecosystems in the world. Australia is no exception, but their protection has lagged behind programmes of terrestrial protection. Freshwater protected areas are an essential component of biodiversity conservation programmes, but a systematic approach to their development in Australia has been slow, and hindered by incomplete ecosystem inventories at State and national levels. We examine this problem and suggest avenues for action. Further, while there is no shortage of relevant legislation and policy for protecting freshwater aquatic systems in Australia, some protective mechanisms have not yet been used, many years after their development. In some places "protection" has been only partially applied without regard to important issues of hydrologic connectivity ? with species extinction as a direct consequence. The most urgent priority is to identify those aquatic ecosystems most at risk. A comprehensive national assessment of the conservation status of freshwater ecosystems should be undertaken immediately. Such an assessment would provide both a platform and an impetus for the systematic expansion of the nation's freshwater protected areas. Political will is then essential for effective conservation, utilizing the plethora of conservation and management tools available.

AbstractRodents account for 40 per cent of living mammal species. Nevertheless, despite an increased interest in biodiversity conservation and their high species richness, Rodentia are often neglected by conservationists. We attempt for the first time a world-wide evaluation of rodent conservation priorities at the genus level. Given the low popularity of the order, we considered it desirable to discuss identified priorities within the framework of established biodiversity priority areas of the world. Two families and 62 genera are recognized as threatened. Our analyses highlight the Philippines, New Guinea, Sulawesi, the Caribbean, China temperate forests and the Atlantic Forest of south-eastern Brazil as the most important (for their high number of genera) ‘threat-spots’ for rodent conservation. A few regions, mainly drylands, are singled out as important areas for rodent conservation but are not generally recognized in global biodiversity assessments. These are the remaining forests of Togo, extreme ‘western Sahel’, the Turanian and Mongolian-Manchurian steppes and the desert of the Horn of Africa. Resources for conservation must be allocated first to recognized threat spots and to those restricted-range genera which may depend on species-specific strategies for their survival.

Argostemma separatum, a new species with free stamens in star-shaped corolla from Mt. Halcon Oriental Mindoro, Philippines is here described and compared with Argostemma diversifolium, the only species of the genus with this type of flower. This species is distinct from A. diversifolium by its indumentum on stem, leaf blades and calyx, smaller leaf blades, fewer flowered inflorescences, shape of stipule and calyx, red tips on corolla lobes, and color of anthers. Based on the recent IUCN categories, the conservation status of A. separatum is Data Deficient (DD) since it was only collected at the type locality.
