Cephalopods of the Philippine Islands

Monsoon surges trigger oceanic eddy formation and propagation in the lee of the Philippine Islands

[1] Two winter monsoon surge events (northerly and easterly) of January 2005 are captured in a one-way coupled atmosphere (8 km resolution) and ocean (3 km resolution) simulation of the Philippines region. Intensified wind jets and wakes in the lee of Mindoro and Luzon Islands induce the generation and migration of a pair of counter-rotating oceanic eddies in the model, with propagation directi...

The pupillary response of cephalopods.

This paper provides the first detailed description of the time courses of light-evoked pupillary constriction for two species of cephalopods, Sepia officinalis (a cuttlefish) and Eledone cirrhosa (an octopus). The responses are much faster than hitherto reported, full contraction in Sepia taking less than 1 s, indicating it is among the most rapid pupillary responses in the animal kingdom. We a...

Global proliferation of cephalopods

Human activities have substantially changed the world's oceans in recent decades, altering marine food webs, habitats and biogeochemical processes [1]. Cephalopods (squid, cuttlefish and octopuses) have a unique set of biological traits, including rapid growth, short lifespans and strong life-history plasticity, allowing them to adapt quickly to changing environmental conditions [2-4]. There ha...

Ptychopteridae, a family of flies (Diptera) new to the Philippine Islands with the description of a new species.

Ptychoptera (Ptychoptera) noonadani sp. nov. is described and is the first record of family Ptychopteridae from the Philippine Islands. A key to males of all Ptychoptera species recorded from the Malay archipelago is presented.
