Avian diversity of Tilyar Lake (28.883–28.879 0N & 76.637 –76.634 0E)  located on the eastern outskirts of Rohtak, Haryana was conducted from May 2017 to April 2018.  A total of 73 avian species belonging to 62 genera and 31 families under 15 orders was observed. Order Passeriformes with 21 species in 12 families dominated the avifauna whereas orders Bucerotiformes, Podicipediformes, and Psittaciformes were poorly represented with a single species each.  Family Anatidae was the most dominant representing 13.89% (n=10) of the total species recorded.  Among the reported species 75% (n=54) were resident while 25% (n=18) were migrant.  Common Pochard Aythya ferina assessed globally as Vulnerable, while Painted Stork Mycteria leucocephala, Oriental Darter Anhinga melanogaster and Black-headed Ibis Threskiornis melanocephalus are assessed as Near Threatened, whereas the rest of the species were in the Least Concern category of the IUCN Red List 2019.  The omnivorous feeding habit was shown by the maximum number of species while frugivorous and granivorous bird species were in the least numbers.  The rich avifaunal diversity of the Tilyar Lake confirms it as a suitable habitat for both resident and migrant bird species. Therefore, the present study suggests the need for incorporation of appropriate protective measures for conservation of the avian heritage of Tilyar Lake, Rohtak.

Quality degradation, modification, and habitat loss are significant threats to bird species. The natural habitat of birds has been modified into residential land and facilities to meet the needs of human life as happened at Tanjungpura University. This study aims to determine of birds species at Tanjungpura University. Observations were carried out from January to March 2019. The method used in collecting the data from bird was “Encounter rates” which was conducted in the morning starting at 6 – 9 am and at 3 - 6 pm. The data obtained were analyzed with the formula of simple abundance scale and frequency of attendance. The birds found at Universitas Tanjungpura are 28 species classified into 23 genera, 17 families, and seven orders. Birds found to have an abundance order scale are classified into abundant, general, frequent and, unusual categories. Birds included in the abundant category are Collocalia fuciphaga and Passer montanus. The types of bird foods at Tanjungpura University consist of frugivore, insectivore, granivore, herbivore, carnivore, piscivore, omnivore, molluscivore, and nectarivore. The value of attendance frequency have range between 10-100%. The bird species with highest frequency of attendance’s value is Passer montanus, Pycnonotus aurigaster, Pycnonotus goiavier, Collocalia fuciphaga, and Anthreptes malacensis.

Ciguatera fish poisoning (CFP) is one of the most frequently reported seafood poisoning diseases. It is endemic to the tropical region and occurs most commonly in the regions around the Pacific Ocean, Indian Ocean, and Caribbean Sea. The principal toxins causing CFP are ciguatoxins (CTXs). In the Pacific region, more than 20 analogs of CTXs have been identified to date. Based on their skeletal structures, they are classified into CTX1B-type and CTX3C-type toxins. We have previously reported species-specific and regional-specific toxin profiles. In this study, the levels and profiles of CTXs in fish present in the tropical western Pacific regions were analyzed using the liquid chromatography–tandem mass spectrometry (LC–MS/MS) technique. Forty-two fish specimens, belonging to the categories of snappers, groupers, Spanish mackerel, and moray eel, were purchased from various places such as Fiji, the Philippines, Thailand, and Taiwan. Only the fish captured from Fijian coastal waters contained detectable amounts of CTXs. The toxin levels in the fish species found along the coastal regions of the Viti Levu Island, the main island in Fiji, and the toxin profiles were significantly different from those of the fish species present in other coastal regions. The toxin levels and profiles varied among the different fish samples collected from different coastal areas. Based on the toxin levels and toxin profiles, the coast was demarcated into three zones. In Zone-1, which covers the northern coast of the main island and the regions of the Malake Island and Korovau, CTXs in fish were below the detection level. In Zone-2, CTX3C-type toxins were present in low levels in the fish. CTX1B-type and CTX3C-type toxins co-occurred in the fish present in Zone-3. The toxin profiles may have reflected the variation in Gambierdiscus spp.

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.

Structural upgrading and industrial dynamismin Pacific Asia—initially Japan, then the Asian NIEs (Newly Industrializing Economies: South Korea, Taiwan, Hong Kong, and Singapore) following closely behind, and most recently, ASEAN 4 (Thailand, Malaysia, Indonesia, and the Philippines)—have been unprecedentedly phenomenal. This regional supergrowth in industrial activities has become the center of attention, but the evolving changes in the political systems and societal structures of the Pacific Asian nations have been, no doubt, equally important, although rather subtle and not so dramatic in appearance.

Abstract The Pacific rat, R. exulans, is an major agricultural and environmental pest in parts of Southeast Asia and the Pacific. Thought to have spread with Polynesian colonists over the past several thousand years, it is now found through much of the Pacific basin, and is extensively distributed in the tropical Pacific. It poses a significant threat to indigenous wildlife, particularly ground-nesting birds, and has been linked to the extinction of several bird species. R. exulans may also transmit diseases to humans.

<p>The sizing of the main span dimensions for new marine bridge crossings needs to consider the current shipping vessels using the waterways and the future growth in marine traffic. Internationally accepted guidelines are used for initial sizing of the navigation clearances, but confirmation of the safe passage of vessels requires simulations to be undertaken. For two major marine bridges planned in the Philippines the marine navigation clearance assessments have been carried out, and the results verified via realistic simulations carried out at the facilities available in the Maritime Academy of Asia and the Pacific (MAAP). This paper outlines methodology of the theoretical calculations and the simulations performed, which confirmed the clearances and informed the design of the required navigation aids.</p>

From Pearl Harbor to Hiroshima and Nagasaki, a group of highly courageous correspondents covered America’s war against Japan. Based on a wealth of previously untapped primary sources, War Beat, Pacific provides the first comprehensive account of what these reporters witnessed, what they were allowed to publish, and how their reports shaped the home front’s perception of some of the most pivotal battles in American history. In a dramatic and fast-paced narrative, the book takes us from MacArthur’s doomed defense on the Philippines and the navy’s overly strict censorship policy at the time of Midway through the bloody battles on Guadalcanal, New Guinea, Tarawa, Saipan, Leyte and Luzon, Iwo Jima and Okinawa, detailing the cooperation, as well as conflict, between the media and the military as they grappled with the enduring problem of limiting a free press during a period of extreme crisis. At the heart of this book are the brave, sometimes tragic stories of reporters like Clark Lee and Vern Haugland of the Associated Press, Byron Darnton and Tillman Durdin of the New York Times, Stanley Johnston and Al Noderer of the Chicago Tribune, George Weller of the Chicago Daily News, Keith Wheeler of the Chicago Times, and Robert Sherrod of Time magazine. Twenty-three correspondents died while reporting on the Pacific War. Many more sustained serious wounds. War Beat, Pacific shows how both the casualties and the survivors deserve to be remembered as America’s golden generation of journalists.

SummaryIdentifying attributes that affect the vulnerability of a species to extinction is important as it allows conservation efforts to be focused on more susceptible species. We assessed whether threatened birds of Guatemala are a random subset of the avifauna, considering their taxonomic affiliation, body size, diet and geographical distribution. We found that threatened bird species in Guatemala were neither taxonomically nor geographically randomly distributed. Large-bodied species and Psittaciformes, Galliformes, Falconiformes and Ciconiformes were among the most threatened groups, and the Pacific slopes of the country hosted more threatened birds than would be expected. Published scientific information regarding Critically Endangered bird species in Guatemala is scant and biased against nocturnal and aquatic species. Research and conservation efforts ought to be oriented toward these species and regions to safeguard the Guatemalan avifauna. This study allows an overall consideration on whether we are conserving the species and areas that are important for threatened birds.
