The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]
, 2000 Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Seasonal and Diel Vocalization Patterns of Antarctic Blue Whale (Balaenoptera musculus intermedia) in the Southern Indian Ocean: A Multi-Year and Multi-Site Study. [PDF]
PLoS ONE, 2016 Passive acoustic monitoring is an efficient way to provide insights on the ecology of large whales. This approach allows for long-term and species-specific monitoring over large areas.

Acoustic behavior of melon-headed whales varies on a diel cycle. [PDF]
, 2015 Many terrestrial and marine species have a diel activity pattern, and their acoustic signaling follows their current behavioral state. Whistles and echolocation clicks on long-term recordings produced by melon-headed whales (Peponocephala electra) at ...

Self-Sensing Control for Soft-Material Actuators Based on Dielectric Elastomers [PDF]
, 2019 Due to their energy density and softness that are comparable to human muscles dielectric elastomer (DE) transducers are well-suited for soft-robotic applications. This kind of transducer combines actuator and sensor functionality within one transducer so

Diel feeding activity of Abudefduf saxatilis on southwestern Atlantic reefs
, 2023 Feeding ecology studies are crucial for understanding energy flow in reef ecosystems. In this study, we used an integrative approach to investigate the diel-feeding ecology of the sergeant-major Abudefduf saxatilis. To examine the possibility of diel-periodicity and size-class differences in foraging behaviour, we tracked fish individuals until their ...

Diel feeding behavior of meiofauna and their relationships with microalgal resources [PDF]
Limnology and Oceanography, 2000 Diel variation of feeding by ostracods and harpacticoid copepod species on microalgae was examined in a mudflat of a Spartina alterniflora saltmarsh. Feeding (gut pigments and consumption of 14C‐labeled algae) and benthic microalgal abundance and composition (HPLC analysis of photopigments) were measured every 6 h over a 48‐h period.
