Abstract The genus Pseudodiaptomus is represented by 19 species in Philippine coastal waters. Of all these species found in the Philippines, P. brehmi Kiefer, 1938 is the only known truly freshwater pseudodiaptomid endemic to this country, which was originally described from Lake Naujan, Mindoro Island. After numerous attempts to find it in its type locality, we concluded that the former is no longer extant in this lake and has now been displaced by the invasive Neotropical calanoid Arctodiaptomus dorsalis (Marsh, 1907). Sampling in Lake Taal, on the nearby island of Luzon, resulted in the surprise discovery of P. brehmi populations coexisting with A. dorsalis. This rediscovery of P. brehmi in Lake Taal and its absence from its type locality, necessitate this report as well as the species’ morphological redescription.

Tintinnids are an essential link between nano- and macro- planktons in the food webs of the marine environment. It is also known that tintinnids are one of themajor components of marine planktonic ciliates and has a cosmopolitan character. In the Philippine archipelago, which is recognized as a center of marine biodiversity, tintinnids checklist has not been done or published. Therefore, a checklist is presented in this study based on a compilation of previous tintinnids studies conducted at the Philippines waters. As a result of the studies done since 1941 up to present, a total of 114 taxa belonging to 14 families and 37 genera were listed. The Philippines coastal waters record a total of 50 species while the open seas document 72 species to date.

Abstract Precipitation in the region surrounding the South China Sea over land and coastal waters exhibits a strong diurnal cycle associated with a land–sea temperature contrast that drives a sea-breeze circulation. The boreal summer intraseasonal oscillation (BSISO) is an important modulator of diurnal precipitation patterns, an understanding of which is a primary goal of the field campaign Propagation of Intraseasonal Tropical Oscillations (PISTON). Using 21 years of CMORPH precipitation for Luzon Island in the northern Philippines, it is shown that the diurnal cycle amplitude is generally maximized over land roughly 1 week before the arrival of the broader oceanic convective envelope associated with the BSISO. A strong diurnal cycle in coastal waters is observed in the transition from the inactive to active phase, associated with offshore propagation of the diurnal cycle. The diurnal cycle amplitude is in phase with daily mean precipitation over Mindanao but is nearly out of phase over Luzon. The BSISO influence on the diurnal cycle on the eastern side of topography is nearly opposite to that on the western side. Using wind, moisture, and radiation products from the ERA5 reanalysis, it is proposed that the enhanced diurnal cycle west of the mountains during BSISO suppressed phases is related to increased insolation and weaker prevailing onshore winds that promote a stronger sea-breeze circulation when compared with the May–October mean state. Offshore propagation is suppressed until ambient midlevel moisture increases over the surrounding oceans during the transition to the active BSISO phase. In BSISO enhanced phases, strong low-level winds and increased cloudiness suppress the sea-breeze circulation.

This paper describes a preliminary field survey of bushy-tailed cloud rats Crateromys spp. and slender-tailed cloud rats Phloeomys in the Philippines in April and May 1990. Brief visits were made to all islands/locations known to support these animals and also to neighbouring areas considered likely to do so. Comparing the results with information from previous surveys suggests that both genera, particularly Crateromys, are more widely distributed than formerly believed, but that some forms are threatened. Three of the four known species of Crateromys are known only from their holotype specimens, one of which awaits description. Another is extinct in its type locality on Ilin Island but may survive on neighbouring Mindoro. These preliminary findings indicate that thorough surveys are required to establish the status of certain species, to investigate the possibility that new species remain undiscovered and to develop conservation plans to reduce the likelihood of further extinctions occurring.

Although the tamaraw occurred on Luzon during the Pleistocene, in historic times this buffalo has been restricted to the Philippine island of Mindoro. There it established a reputation for aggressiveness that made it widely known in the Philippines, but it was not described for science until 1888. It has been estimated that 10,000 tamaraw Bubalus mindorensis occupied Mindoro island in 1900 but by 1949 numbers had declined to 1000 animals, and in 1953 fewer than 250 remained. In 1969 Harrisson estimated that about 100 survived in three of their four known areas. Poaching was the main cause of the decline. Thanks to Harrisson's and General Lindbergh's efforts, 1969 also marked the start of the Philippine Government's tamaraw conservation effort, and wardens and guards were posted at the Mt Iglit Game Refuge and Bird Sanctuary in Occidental Mindoro. Between May 1972 and March 1974 I conducted a tamaraw study on 2000 hectares of the refuge where the major tamaraw population was to be found.

This paper describes the vertical movements, behavior and habitat utilization of an electronically tagged adult yellowfin tuna (Thunnus albacares) after 17 days of liberty in the Philippines based on analyses of 23,845 datapoints recorded from a recovered electronic popup tag. The exhaustive set provides a way to describe the vertical movement as well as a range of behaviors exhibited by the fish. We used the daily time records of depth and temperature from the vertical dives of the fish at different times of the day (nocturnal, dawn, diurnal, dusk) to describe fish behavior and to characterize its three deep dives. The fish stayed 23% and 24% of its time at warmer waters of 28 0C and 30 0C. It also spent 15% of its time at 26 0C and 10% of its time at colder waters of 20 0C and 22 0C. The daily differences in temperatures fluctuated from 12.10C to 30.1 0C with the daily average temperature of 24.2 0C. Swimming speeds determined show the maximum vertical ascent speed that the fish registered reached 1.53m/s swimming from a depth of 195m to 104m during a dusk. The maximum vertical descent speed reached 1.38m/s from a depth of 78m down to 161m. The deepest dive of the fish started from a U-shaped diving profile that lasted for almost 32 minutes and then followed by another U-shaped dive for 12 minutes before a deep dive and fast vertical ascent. The total duration of its dives differ with water depth: 0-50m (1.89 hours), 50-75m (4.78 hours), 75-100m (3.35 hours), 100-125m (1.69 hours), 125-150m (1.69 hours). Such swimming behavior provides valuable information on the vulnerability of tunas particularly the juvenile fishery.   Keywords - Archival tag, fish aggregating device (FAD), Mindoro Island, West Philippine Sea, Yellowfin tuna, Philippines

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.
