Abstract:

The taxonomy of the Sundathelphusa philippina (von Martens, 1868) species group (Brachyura; Gecarcinucidae) from the Philippines is revised, and two new species are described. Sundathelphusa philippina sensu stricto is here restricted to the Bicol Peninsula of southern Luzon, and to the islands of Samar and Leyte. It is one of the largest freshwater crabs in the archipelago, reaching carapace widths of more than 53 mm. Sundathelphusa cebu sp. nov. from Cebu Island is superficially similar to S. philippina in morphology but can be separated by a suite of carapace characters. Sundathelphusa quirino sp. nov. from northern Luzon is the most distinct of the three taxa, with a distinctly more swollen carapace, relatively wider male pleon and a straighter male first gonopod. Sundathelphusa spelaeophila Stasolla, Abbarchi & Innocenti, 2015, is also shown to be a junior synonym of S. philippina sensu stricto.

Abstract:

Until now, two species of Clidicus were known to occur in the Philippines, both inhabiting Mindanao. The scarcity of published records (merely six known Philippine specimens of this genus) suggested that Clidicus was rare in this country. We here falsify this view, by describing five new species and providing new records of the previously known species, based on a material of over 80 specimens collected on Mindanao and Luzon. Clidicus forceps Cheng, Yin & Jałoszyński, sp. n., C. interfector Jałoszyński, Cheng & Yin sp. n., C. kalis Jałoszyński, Cheng & Yin sp. n., C. occisor Jałoszyński sp. n., and C. shavrini Jałoszyński sp. n., are described. Clidicus crocodylus Jałoszyński, previously known to occur on Mindanao, is for the first time recorded in Luzon.

Journal of Mammalogy 102, no. 3 (April 23, 2021): 909–30. http://dx.doi.org/10.1093/jmammal/gyab023.

Full text

Abstract:

Abstract The 18 extant members of the Tribe Phloeomyini, the “cloud rats,” constitute an endemic Philippine radiation of arboreal herbivores that range in size from ca. 18 g to 2.7 kg, most occurring in cloud forest above 1,200 m elevation. Although calibrated phylogenies indicate that the Phloeomyini is estimated to have begun diversifying within the Philippines by ca. 10–11 million years ago, no extinct fossil species have been described, severely limiting our understanding of this distinctive radiation. Our studies of fossil and subfossil small mammal assemblages from the lowland Callao Caves complex in NE Luzon, Philippines, have produced specimens of Phloeomyini that date from ca. 67,000 BP to the Late Holocene (ca. 4,000 to 2,000 BP). We identify three extinct species that we name as new members assigned to the genera Batomys, Carpomys, and Crateromys, distinguished from congeners by body size, distinctive dental and other morphological features, and occupancy of a habitat (lowland forest over limestone) that differs from the high-elevation mossy forest over volcanic soils occupied by their congeners. Batomys cagayanensis n. sp. is known only from two specimens from ca. 67,000 BP; Carpomys dakal n. sp. and Crateromys ballik n. sp. were present from ca. 67,000 BP to the Late Holocene. These add to the species richness and morphological diversity of this endemic Philippine radiation of large folivores, and show specifically that the lowland fauna of small mammals on Luzon was more diverse in the recent past than it is currently, and that Luzon recently supported five species of giant rodents (ca. 1 kg or more). All three occurred contemporaneously with Homo luzonensis, and two, the new Carpomys and Crateromys, persisted until the Late Holocene when multiple exotic mammal species, both domestic and invasive, were introduced to Luzon, and new cultural practices (such as making pottery) became evident, suggesting that modern humans played a role in their extinction.

Numerous features of its external morphology distinguish it from other congeners, including the presence of a distinct color pattern, body size, and a unique combination of scale counts. The new species has been found on karst outcrops and cave systems at low elevation. The new species typifies the rapidly expanding known diversity of Philippine gekkonid lizards, and is the third species in the genus to be described in the last three years.

Abstract:

The southeast Asian holoparasite genus Rafflesia Brown (1821: 207; Rafflesiaceae) is famous for producing the largest flowers on record (Kuijt 1969). Following a series of discoveries of new Rafflesia species and populations, the Philippines recently emerged as one of the centers of its diversity. It is home to no less than ten currently recognized Rafflesia species (Barcelona et al. 2009, Balete et al. 2010). Here, we report two discoveries that resulted from recent fieldwork in the Mts. Banahaw - San Cristobal Protected Landscape in Luzon and show how these new data impact the taxonomy and biology of Philippine Rafflesia.

The diversity of the Agraeciini spine-headed katydids (Orthoptera: Tettigonioidea: Conocephalinae) in Southeast Asia remains poorly known, with species still awaiting discovery. Recent field collections in the Philippines resulted in the discovery of three novel species and redescription of two known species of Agraeciini, namely, (1) Anthracites furvuseques sp. nov. from Siargao in Mindanao, a species close to A. major Hebard, 1922; (2) Axylus mabinii sp. nov. from Luzon: (3) a new variant in Axylus c.f. philippinus (Hebard, 1922); (4) Salomona lumadae sp. nov. from Siargao in Mindanao; and (5) Salomona brevicollis Stål, 1877 comb. resurr. is a valid species distinct from Salomona maculifrons Stål, 1877.

Full text

Abstract:

The fi rst joint study by Russian and Philippine archaeologists addresses an unusual variant of a burial tradition distributed in Island Southeast Asia – burials in anthropomorphic clay jars, found in Ayub Cave (southern Mindanao Island, Philippines), excavated by specialists from the National Museum of the Philippines in 1991–1992, and tentatively dated to 500 BC to 500 AD. Of special interest are lids of jars shaped as painted human heads with individualized facial features and expressions. The fi nds suggest that Ayub Cave was a necropolis of the tribe elite, and that vessels were produced by a special group of potters using elaborate “prestige technologies”. The Ayub ceramic collection has various parallels relating to clay fi gurines and decoration including painting, among Late Neolithic and Early Metal Age assemblages from the Philippines (Luzon, Palawan, and Negros Islands), Indonesia (Sumba, Flores, and Bali Islands), and other regions of the Pacifi c Basin from Japan (Jomon) and Korea (Early Iron Age burials) to Vanuatu Islands (Lapita culture). These parallels suggest that the source of the anthropomorphic symbolism was the Austronesian migration with one of its routes passing from southern China via Taiwan, the northern Philippines, Mariana Islands, and further south to Melanesia and Polynesia.

Platymantis biak is assigned to the primarily arboreal Platymantis guentheri Species Group, and is distinguished from these and other congeners by features of its external morphology and preferred terrestrial limestone microhabitat. Several distinguishing morphological characters include a moderately large body (32.3–39.9 mm SVL for 23 males and 37.4–42.4 mm SVL for 8 females), moderately expanded finger discs and slightly expanded toe discs, smooth skin, and limb banding pattern. The new species is yet another species in a rapidly growing group of newly discovered Philippine forest frogs with preferences for forested, karst habitats.

Abstract:

The First Association of Southeast Asian Nations (ASEAN) Committee on Disaster Management Meeting established a framework for ASEAN-US cooperation on the Disaster Management Program in 2003, focusing on capability building for the Incident Command System (ICS). The ICS was then adopted as part of the on-scene disaster response system in the Republic of the Philippines as enacted by the Philippine Disaster Risk Reduction and Management Act in 2010. This study investigates the process of adopting the ICS, its current status, and future issues through interview surveys of local and national governments in the Philippines. After adopting and implementing of the ICS as the national disaster response system for the Philippines is investigated, the current status of the ICS at the local government level is surveyed in a flood-prone area of the Pampanga River basin in central Luzon. Results show that the ICS has been adopted on all levels of government – national, regional, provincial, municipal, and barangay, i.e., the country’s smallest administrative division. Each local government level has incorporated the ICS into its contingency plan. Several issues related to future disaster response planning and capacity building are then reviewed.

Full text

Abstract:

When the mission of the Basque adelantado Miguel López de Legazpi reached Luzon – the northernmost isle of the Philippine archipelago – in 1570, the ambitious Spanish conquistadores met the ‘Sangley’ merchants for the first time. During the 1570s many Chinese junks started to connect Manila with the ports of Fujian province and transformed the Philippine capital in a crossroads of the silk to silver exchange between China, Japan and the two Americas. Following the establishment of the Manila-Acapulco-Callao triangular trade line and with the influx of the precious ‘reals of eight’ from Mexico, the so-called ‘Naos de China’ started to enrich both the Spaniards and the ‘Sangleys’, triggering an irreversible process that led to the establishment of a ‘Galleon System’ in just two decades. This paper will discuss the role of Chinese trade in the Philippines at the close of the 16th century from the founding of Manila in 1571 to the establishment of the ‘Galleon System’ by the early 1590s.

Abstract:

Begonia adamsensis from the northern part of Luzon Island is described as a new species endemic to the Philippines. This is the latest addition to the Begonia sect. Baryandra, making the total of Philippine begonias in this section to 56 species. It resembles Begonia hernandioides because its leaves are peltate, with a broad base, acuminate tip, nearly entire margin, and a glabrous peduncle; however, it differs significantly from B. hernandioides because of its broadly ovate red stipule, pubescent petiole, elliptic peltate leaf, pubescent abaxial lamina, and 4 perianth segments in the carpellate flower. Only about 200 individuals were found in a 100-m area that is being developed as a tourist spot in the locality, hence Begonia adamsensis is hereby proposed as critically endangered.

Full text

Abstract:

The Vigan-Aggao Fault is a 140-km-long complex active fault system consisting of multiple traces in the westernmost part of the Philippine Fault Zone (PFZ) in northern Luzon, the Philippines. In this paper, its traces, segmentation, and oblique left-lateral strike-slip motion are determined from horizontal and vertical displacements measured from over a thousand piercing points pricked from displaced spurs and streams observed from Google Earth Pro satellite images. This work marks the first instance of the extensive use of Google Earth as a tool in mapping and determining the kinematics of active faults. Complete 3D image coverage of a major thoroughgoing active fault system is freely and easily accessible on the Google Earth Pro platform. It provides a great advantage to researchers collecting morphotectonic displacement data, especially where access to aerial photos covering the entire fault system is next to impossible. This tool has not been applied in the past due to apprehensions on the positional measurement accuracy (mainly of the vertical component). The new method outlined in this paper demonstrates the applicability of this tool in the detailed mapping of active fault traces through a neotectonic analysis of fault-zone features. From the sense of motion of the active faults in northern Luzon and of the major bounding faults in central Luzon, the nature of deformation in these regions can be inferred. An understanding of the kinematics is critical in appreciating the distribution and the preferred mode of accommodation of deformation by faulting in central and northern Luzon resulting from oblique convergence of the Sunda Plate and the Philippine Sea Plate. The location, extent, segmentation patterns, and sense of motion of active faults are critical in coming up with reasonable estimates of the hazards involved and identifying areas prone to these hazards. The magnitude of earthquakes is also partly dependent on the type and nature of fault movement. With a proper evaluation of these parameters, earthquake hazards and their effects in different tectonic settings worldwide can be estimated more accurately.

Abstract:

Katydids from the subfamily Meconematinae sing at ultrasonic frequencies. Owing that many of them are nocturnal, elusive and low in abundance (since they are predatory), there is a dearth of information on these katydids and their bioacoustics, especially for species in the understudied yet mega-diverse Southeast Asia. Recent orthopteran surveys in Laguna, Luzon Island in the Philippines led to the discovery of two interesting Meconematinae katydids. Based on the collection, we describe a new species of Phisidini: Neophisis (Indophisis) montealegrei sp. nov. We also describe the male for the first time and redescribe the female of Asiophlugis philippina. The ultrasonic calling songs of both Meconematinae are also recorded, analysed and described here.

Abstract:

Abstract Cloud-resolving simulations are used to evaluate the importance of topography to the diurnal cycle (DC) of precipitation (DCP) over Luzon, Philippines, and surrounding ocean during the July–August 2016 boreal summer intraseasonal oscillation (BSISO) event. Composites of surface precipitation for each 30-min time increment during the day are made to determine the mean DCP. The mean DCP is computed separately for suppressed and active BSISO conditions and compared across three simulations with varying topography—flat, true, and doubled topographic height. The magnitude of the topographic height helps to dictate the timing, intensity, and location of diurnal precipitation over and near Luzon. For example, the mean DCP in the true topography run peaks 1.5 h later, is broader by 1 h, and has a 9% larger amplitude during active conditions relative to suppressed conditions. By contrast, the flat run mean DCP is earlier and narrower by 0.5 h with a 5% smaller amplitude during active conditions versus suppressed conditions. Within the suppressed or active BSISO conditions, the mean DCP peak and amplitude increase as the topographic height increases. The presence of elevated topography focuses precipitation over the coastal mountains during suppressed conditions, while dictating which side of the domain (i.e., east Luzon and the Philippine Sea vs west Luzon and the South China Sea) more precipitation occurs in during active conditions. These topographic-induced changes are discussed in terms of mechanical and thermodynamic forcing differences between the two large-scale BSISO regimes for the three runs.

Abstract:

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.

Abstract:

The systematics of the wide-ranging southeast Asian colubrid snake Dendrelaphis caudolineatus (Gray, 1834) wasinvestigated on the basis of multivariate analyses of morphological and coloration data for 131 museum specimensrepresenting 28 geographically isolated populations. The results demonstrate that the current taxonomy of D.caudolineatus underestimates species diversity in the Philippines. The following revisions are implemented. 1)Populations from the Philippine island Palawan and adjacent islands currently referred to D. c. caudolineatus (Gray, 1834)are described as a new species, D. levitoni sp. nov. 2) Populations from the Philippine islands Negros, Panay, Mindoroand Masbate, currently assigned to D. c. terrificus (Peters, 1872) and D. c. luzonensis Leviton, 1961 are referred to D.fuliginosus Griffin 1909, which is revalidated. 3) Populations from the southern Philippine islands Basilan, Mindanao,Cebu, Bohol, Leyte, Samar, Polillo, Kalotkot, Catanduanes as well as Southeast Luzon currently referred to D. c. terrificus(Peters, 1872) are referred to D. philippinensis Günther, 1879 which is revalidated. 4) The population from Sulawesi isreferred to D. terrificus (Peters, 1872). Currently regarded as a polytypic species composed of five subspecies, D.caudolineatus is here considered to be a monophyletic group comprising eight species. The distributions of these eightspecies correspond largely with aggregate island complexes formed during periods of reduced sea level during the Pleistocene. However, some deviations indicate post-Pleistocene dispersals across sea barriers.

Abstract:

Christian Filipino legislators in the bicameral US civil administration played a hitherto unacknowledged role in pushing for the colonisation of Mindanao, as part of the Philippines, by proposing a series of Assembly bills (between 1907 to 1913) aimed at establishing migrant farming colonies on Mindanao. This legislative process was fuelled by anger over the unequal power relations between the Filipino-dominated Assembly and the American-dominated Commission, as well as rivalry between resident Christian Filipino leaders versus the American military government, business interests and some Muslim datus in Mindanao itself for control over its land and resources. Focusing on the motives and intentions of the bills' drafters, this study concludes that despite it being a Spanish legacy, the Christian Filipino elite's territorial map — emphasising the integrity of a nation comprising Luzon, the Visayas and Mindanao — provided the basis for their claim of Philippine sovereignty over Mindanao.

Abstract:

Our knowledge of the freshwater cyclopid copepods of the Visayas Islands remains poor as compared to other terrestrial and aquatic fauna. This study focuses on two genera, Mesocyclops and Thermocyclops, which are common components of lake plankton communities. This study included specimens collected from 59 sampling sites found in major islands (Panay, Negros, Cebu, Bohol, Leyte and Samar) and a small island (Pacijan) in the Visayas region. Four species of Mesocyclops and three species of Thermocyclops were identified. This includes the first record of Mesocyclops woutersi in the Philippines, which was so far unknown from insular SE Asia. The endemic Mesocyclops microlasius, previously reported from Luzon Island, was also found in Lake Danao (Pacijan Island). An identification key to Philippine species of Mesocyclops and Thermocyclops is herein provided. Geographic distribution and possible causes of the low number of species observed and their implications for further faunal studies are also discussed.

Abstract:

Thirteen strains of Xanthomonas campestris pv. vesicatoria, causal agent of bacterial spot of pepper (Capsicum spp.) and tomato (Lycopersicum spp.), were isolated from six different pepper fields in the vicinity of Bongabon, Luzon, the Philippines. The strains were characterized based on sensitivity to copper and streptomycin, physiological tests, analysis of whole cell fatty acids (fatty acid methyl ester; FAME), serology, amplification of the 16S–23S rDNA spacer region, pathogenicity, and virulence on pepper and tomato differential genotypes as previously described (1,2). All of the Philippine strains were copper resistant (50 μg/ml), and streptomycin sensitive (20 μg /ml). None of the strains were pectolytic or amylolytic. FAME analysis showed that all strains had similar fatty acid profiles, and matched the strains to X. campestris (similarity indices [S.I.] = 0.186–0.455). With the universal primers 4F/7R, a DNA fragment (680 bp) was amplified from 16S–23S rDNA spacer regions of all Philippine strains. Serological fingerprints of the strains with a set of eight monoclonal antibodies (MAbs) in indirect enzyme-linked immunosorbent assay showed that all Philippine strains were serovar A1. Existence of the avrRxv gene in X. campestris pv. vesicatoria race T1 strains was also confirmed for all Philippine strains by amplifying a DNA fragment (approximately 0.7 kb) with the primer set RST 27/28. This is genetic evidence for race identity of the Philippine strains with T1. However, hypersensitive test results on pepper and tomato differential lines identified the Philippine strains as T2P7. These results showed that X. campestris pv. vesicatoria strains may contain the avrRxv gene, but it may not be functional. This is the first report of the observation of X. campestris pv. vesicatoria race T2P7 on pepper. References: (1) H. Bouzar et al. Phytopathology 84:664, 1994; (2) F. Sahin and S. A. Miller.

Abstract:

Rickettsia and Coxiella burnetii are zoonotic, tick-borne pathogens that can cause febrile illnesses with or without other symptoms in humans, but may cause subclinical infections in animals. There are only a few reports on the occurrence of these pathogens in cattle and water buffalo in Southeast Asia, including the Philippines. In this study, molecular detection of Rickettsia and C. burnetii in the blood and in the Rhipicephalus (Boophilus) microplus ticks of cattle and water buffalo from five provinces in Luzon Island of the Philippines was done. A total of 620 blood samples of cattle and water buffalo and 206 tick samples were collected and subjected to DNA extraction. After successful amplification of control genes, nested PCR was performed to detect gltA of Rickettsia and com1 of C. burnetii. No samples were positive for Rickettsia, while 10 (cattle = 7, water buffaloes = 3), or 1.6% of blood, and five, or 1.8% of tick samples, were C. burnetii-positive. Sequence analysis of the positive amplicons showed 99–100% similarity to reported C. burnetii isolates. This molecular evidence on the occurrence of C. burnetii in Philippine ruminants and cattle ticks and its zoonotic nature should prompt further investigation and surveillance to facilitate its effective control.

Abstract:

Nepenthes maximoides sp. nov. (Sect. Alatae) is described and assessed as Critically Endangered (Possibly Extinct) from Luzon, Philippines and appears unrecorded in 110 years. The spectacular, large, narrowly funnel-shaped upper pitchers, lids with recurved basal and filiform apical appendages, unlike any other species in the Philippines, closely resemble those of N. maxima (Sect. Regiae) of Sulawesi–New Guinea, likely due to convergent evolution. Following recent phylogenomic analysis, sect. Alatae is divided into two, Sect. Alatae sensu stricto of Luzon to Sibuyan (including N. maximoides), and Sect. Micramphorae, expanded and recircumscribed to encompass those species of the southern Visayas, and Mindanao. A key is provided to the six species now recognised in the newly narrowly recircumscribed Sect. Alatae. The number of Nepenthes species recorded from Luzon has increased from two in 2001, to eight in 2020, all but one of which are endemic to that island, and four of which appear to be point endemics.

Abstract:

Flooding is a perennial problem in the Philippines during the monsoon season intensified by the effects of typhoon. On average, there are 20 typhoons that enter the Philippine Area of Responsibility (PAR), and many of these make landfall causing catastrophic aftermath. Extreme rainfall events could lead to flooding in the downstream floodplain and landslide in mountainous terrains. In this study, which is for the case of Calumpang River that drains to the populated and developing region of Batangas City, the focus is on flooding in the floodplain areas. The river was modelled using LiDAR digital elevation model (DEM) that has an accuracy of 20cm in the vertical and 50cm in the horizontal. The result of this is river hydraulic model that can be used to accurately generate flood inundation simulations and flood hazard maps.

Abstract:

SummaryFieldwork on the distribution, status and ecology of birds was conducted in the northern Sierra Madre mountain range, Luzon, Philippines, during March–May 1991 and March-May 1992. The findings show the area to be one of the most important for conservation of threatened species of birds in all Asia. The results are here combined with evidence from earlier surveys by other searchers. Fourteen threatened and 18 near-threatened species are now known from the area. This paper reports on all the threatened and near-threatened resident species of the island of Luzon, with special emphasis on their occurrence in the Sierra Madre mountains. In addition, the paper treats species with very limited global distribution that breed in Luzon, and lists species of forest birds endemic to the Philippines that have not previously been reported from the Sierra Madre mountains. Maps show the known sites for 17 species of special concern for conservation. New data on the altitudinal distribution of threatened and near-threatened species suggest that it is essential to protect primary forest at all elevations.
