Abstract:

The Polyrhachis (Myrma) cyaniventris species group is established and described. It contains Polyrhachis (Myrma) cyaniventris F. Smith, 1858 and a species new to science, P. (Myrma) pirata sp. n. At present knowledge the clade is restricted to the northern and eastern islands of the Philippine archipelago. Polyrhachis cyaniventris is recorded from central and southern Luzon, Catanduanes, Mindoro, Samar, and Leyte; P. (Myrma) pirata sp. n. from central and southern Luzon, Mindoro and Samar.

In the vertical distribution, the dissipation rates below the surface mixed layer were predominantly high in the thermocline where shear and stratification were strong. In the regional distribution, high dissipation rates and diapycnal diffusivities were observed in the region to the west of the Luzon Strait, with an average dissipation rate and diapycnal diffusivity of 8.3 ×

Risk assessment based on population of barangays can be determined using the Population Exposure Index (PEI), Population Risk Level (PRL) cohorts, and land area.

Abstract:

The distribution and source sites of nonlinear internal waves (NLIWs) northeast of Hainan Island were investigated using satellite observations and a wavefront propagation model. Satellite observations show two types of NLIWs (here referred to as type-S and type-D waves). The type-S waves are spaced at a semidiurnal tidal period and the type-D waves are spaced at a diurnal tidal period. The spatial distribution of the two types of NLIWs displays a sandwich structure in which the middle region is influenced by both types of NLIWs, and the northern and southern regions are governed by the type-S

Abstract:

Multiwave interference plays a crucial role in shaping the spatial variations of internal tides. Based on a combination of in situ mooring and altimeter data, interference of semidiurnal internal tides was investigated in the northern South China Sea. Mooring observations indicate the observed kinetic-to-potential energy ratio and group speed are both relatively lower than the theoretical values of mode-1 semidiurnal internal tides, indicating the presence of partly-standing waves. This is consistent with the altimeter result that the mooring was located at the antinode within the interference

During a rapid biodiversity assessment conducted in December 2015, six species of bat flies belonging to the genera <em>Brachytarsina</em> Macquart, <em>Eucampsipoda</em> Kolenati, <em>Leptocyclopodia</em> Theodor, <em>Megastrebla</em> Maa, and <em>Nycteribia</em> Latreille were documented. Before this paper, there were no published records of bat flies on the island, making this paper the first documentat

Abstract:

Work-life balance remains a continuous concern in every workplace due to its influence on employee performance. Hence, this study determined the extent of the work-life balance of state auditors in Southern Luzon in terms of self-management, time management, stress management, and leisure management relative to age, length of service, and audit sector. Additionally, it assessed the level of job performance as to quality, efficiency, and timeliness. Likewise, the work-life balance and job performance were compared when grouped according to demographics. Lastly, it ascertained the relationship b

Abstract:

Using Estimating the Circulation and Climate of the Ocean (phase 2, ECCO2) reanalysis products from 1997 to 2019, this study analyzes the spatiotemporal features of the eddy available gravitational potential energy (EAPE) in the South China Sea (SCS). The results indicate that the EAPE accounts for 64% of the total APE in the SCS with the climatological mean. The 2D EAPE distribution images manifest show high-value regions which are generally consistent with the eddy distributions. One region is located around 21° N and west of the Luzon Strait, the second around 17° N and near Luzon Island, a

Abstract A new species of freshwater crab belonging to a group of species morphologically similar to Sundathelphusa philippina (Von Martens, 1868) is described from highlands in the province of Batangas, southern Luzon, Philippines. Sundathelphusa roberti new species, however, differs from members of this group by the position and strength of the epigastric and postorbital cristae, form of the posterior epistomal margin, shape of the third maxillipeds, and structure of the male first gonopod. The new taxon is the 35th species of Sundathelphusa known from the Philippines.

Abstract Internal tide generation, propagation, and dissipation are investigated in Luzon Strait, a system of two quasi-parallel ridges situated between Taiwan and the Philippines. Two profiling moorings deployed for about 20 days and a set of nineteen 36-h lowered ADCP–CTD time series stations allowed separate measurement of diurnal and semidiurnal internal tide signals. Measurements were concentrated on a northern line, where the ridge spacing was approximately equal to the mode-1 wavelength for semidiurnal motions, and a southern line, where the spacing was approximately two-thirds that.

Earthworm specimens were collected from the Bicol region, southern Luzon Island, the Philippines. Seven species of the genus Pheretima Kinberg, 1867 are described from Bicol: Pheretima bicolensis sp. nov., Pheretima viracensis sp. nov., Pheretima camarinensis sp. nov., Pheretima doriae sp. nov., Pheretima batoensis sp. nov., Pheretima buhiensis sp. nov., and Pheretima gorasi sp. nov. The seven new Pheretima species all key to the urceolata group in Sims & Easton (1972) with a single pair of spermathecal pores in 5/6.

Abstract:

Aim: Plants distributed between southern Taiwan and the north of the Philippines are spread among numerous small islands in an area crossed by the powerful Kuroshio current. Oceanic currents can be effective seed-dispersal agents for coastal plant species. Moreover, the Luzon Strait is an area prone to tropical cyclones. The aim of this study is to look at the dispersal capability of an endangered coastal plant species, the Mearns fig (Ficus pedunculosa var. mearnsii), using both experimental and population genetics methods.

Abstract:

The growth and expansion of maritime trade in the first millennium CE altered the musical landscape of Asia, from earlier Austronesian and Austroasiatic migrations, to the early contacts with India, China, Arabia, and the continuing navigation towards the Pacific and Oceania. Much later in the tenth century, Chinese chronicles describe that peoples from the south called Luzoes (Luzon, Philippines) had invaded its southern shores, while Indian histories record the voyages of sailors from western Indonesia. By the eighth century, Austronesian languages from Borneo had spread towards Madagascar.
