Cucarachas en cuevas de Filipinas

Un nuevo trabajo firmado por Vanessa Rona P. Mag-Usara y Olga M. Nuñeza en la revista Extreme Life, Biospeology & Astrobiology y titulado: "Diversity and relative abundance of cockroaches in cave habitats of Siargao Island, Surigao del Norte, Philippines", nos da la diversidad de cucarachas en cuevas de esta Isla de las Filipinas.


El resumen de este trabajo en inglés es:

ABSTRACT:
Cave-dwelling cockroaches are poorly known and mostly unaccounted for in cave habitats. The diversity and relative abundance of cockroaches were determined by utilizing pitfall traps, quadrat and modified cruising methods in cave habitats of Siargao Island Seascape and Landscape. Four species were recorded in three out of ten cave sites with Polyzosteria limbata as the most abundant and commonly distributed. Buho cave had the highest abundance of cockroaches. Cave-dwelling cockroaches were found to have affinity to temperatures between 27˚C to 28˚C and relative humidity of 85% and above. Microhabitat preferences of cockroaches were noted to be the dense desiccated guano deposits and boulders found at the inner zones of caves. More assessments on caves in Mindanao are needed for a complete database and for a better grasp on the ecology of cave-dwelling cockroaches.
