Pelagic Marine Litter

Floating marine debries

A threat to all life in the oceans

Summary: Marine litter presents now a global threat at different scales in the Ocean. A large diversity of marine life is being affected and all information available is currently relevant.


Objectives: Study the diversity, density and dispersion of floating marine debries.


Methods & Data: Transects with visual counts during boat tours (whale watching, birdwatching, coastal tours).



Partners: MARE - Marine and Environmental Sciences Centre; University of the Azores. University of Lisbon

Habitat and Ecology of the Azores Noctule

Nyctalus azoreaum

The only diurnal bat in the world!

Summary: First long term study to characterize habitat and seasonal patterns of activity of the only species of mammal endemic of the Azores. The Azorean noctucle is the only diurnal bat species in the world. Originated from lesser noctules (Nyctalus leisleri) which colonized the Azores. Smaller, lighter and with a darker fur it also echolocates at higher frequencies and much of its ecology remains unknown.


Objectives: Understand the habitat and activity patterns of the Azores noctule


Methods & Data: Point counts of 10 minutes, including total number of passages and largest number of animals at sight.


Publications: N/A
