Dr. Vallejo and colleagues receive 2019 NAST Outstanding Award

It is with great pride and honor that we announce the prestigious award given to two of our very own, Dr. Benjamin Vallejo Jr. (Associate Professor- UP Diliman and Q-quatics BOT Secretary) and Jeniffer Conejar-Espedido (Research Officer-Q-quatics), together with their colleague, Leanna Manubag (Ecosystem Management Specialist-DENR – Biodiversity Management Bureau), for their work on “The ecology of an incipient marine biological invasion: The Charru mussel Mytella charruana d’Orbignyi, 1846 (Bivalvia: Mytilidae) in Manila Bay, Luzon, Philippines”. This award was given by the National Academy of Science and Technology during its 41st Annual Scientific Meeting held on July 10-11, 2019 at EDSA Shangri-La Manila, Ortigas, Mandaluyong City (Philippines).  This paper was published in Philippine Journal of Science 146(4):483-492 in 2017.


Abstract: The study documents the initial colonization ecology of the Western Hemisphere’s non-indigenous mytilid Mytella charruana in the Port of Manila, Manila Bay. As part of a monitoring effort to document fouling communities using PICES collectors, a recruitment pulse of Mytella charruana was detected in Jul 2014. The recruits have persisted and established in the port. Also noted was the possible recruitment competition with other indigenous and non-indigenous bivalve species. Mytella recruits during the onset of the southwest monsoon rainy season. Based on Canonical Correspondence Analysis of recruit abundances with water quality parameters, Mytella, the green mussel Perna viridis, Musculista, and Brachidontes have a lower salinity niche and recruits on Amphibalanus and Hydroides biogenic substrates. Also examined was the possible competition between Mytella and Perna viridis, since these species have been used for mariculture. Perna is traditionally cultured in Manila Bay, while Mytella is proposed as a new species for mariculture in the Philippines. Based on the results and its physiological ecology, Mytella is likely to have a competitive advantage over Perna in estuaries like Manila Bay.
