- Vegetative dynamics and sexual reproduction of monospecific Thalassia hemprichii meadows in the Kalayaan Island GroupRollon, Rene N.; Cayabyab, Napo M.; Fortes, Miguel D. (Elsevier BV, 2001-11)We surveyed eight offshore islands and shoals in the Philippine Kalayaan Island Group. The aims were to (1) map the distribution, (2) evaluate the demographic status, (3) elucidate the vegetative growth dynamics, and (4) quantify the sexual reproductive capacity of Thalassia hemprichii meadows in the region. We combined age reconstruction techniques and in situ estimations to attain such goals. We found T. hemprichii meadows only in Pag-asa Island. These meadows were generally young (mean age <1 year) and rapidly expanding (net recruitment ∼0.8 ln units per year). This was consistent with the horizontal rhizome apices being dense (162–334 apex m−2) and fast-spreading (36–56 cm per apex per year). The results for in situ measurements of plastochron interval (9.2 days), and relative leaf (3.7 cm2 cm−2 per shoot per day) and areal growth rates (2.3–2.7 cm2 per shoot per day) were similar to those of previous studies. The variation in the vertical internodal lengths showed a unimodal annual trend more distinctly in the south than in the north station, suggesting local, small-scale differences in environmental conditions between stations. Flower production was clearly seasonal, peaking around January 1999. Fruiting (128–134 m−2) and seedling recruitment (22–32 m−2) values were high, indicating a substantial contribution of sexual reproduction to the rapid expansion or meadow maintenance. The apparent disjunct occurrence of such young and highly reproductive meadows in the region merits further investigation.
- Fishers group rejects more US military bases in PHFernandez, Daniza; Go, Joshua (Panay News, Inc., 2022-11-24)A fishers’ group rejected on Tuesday further construction of United States (US) military bases in the Philippines and accused Vice President Kamala Harris of aiming to anger China with her visit. The Armed Forces of the Philippines said that the US is looking into building Enhanced Defense Cooperation Agreement facilities in five more locations throughout the archipelago. These additional sites are seen to bolster security cooperation between the two countries and provide extra protection for the Philippines.
- Senator wants to stop China’s island-building activities at seaTadalan, Charmaine A. (BusinessWorld Publishing Corporation, 2020-04-28)A Philippine senator on Monday filed a resolution seeking legal and diplomatic approaches to force China to stop its “destructive” reclamation activities in the South China Sea. Senator Risa N. Hontiveros-Baraquel also said the government should force China to pay the Philippines P200 billion for damages on reefs within its territory in the past six years. “China’s sense of entitlement to our seas has caused severe and irreparable harm to our ecosystems,” Ms. Baraquel said in a statement. She estimated damages caused by China’s reclamation activities at P33 billion a year, assuming the value per hectare of a coral reef is $353,429 based on a 2012 study by Ecosystem Services.
