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(-

Diel changes in adipokinetic response and walking activity of Pyrrhocoris apterus (Heteroptera) in relation to physiological status and wing dimorphism

European Journal of Entomology, 2001
Three experimental groups of adult females of Pyrrhocoris apterus (reproductive brachypterous, diapausing brachypterous, and macropterous with non-diapause type of reproductive arrest) were analysed for their dose dependency of adipokinetic response ...

Seasonal depth and temperature use, and diel movements of lake trout (Salvelinus namaycush) in a subarctic lake

Arctic Science, 2019
We conducted a multi-year acoustic telemetry study of lake trout (Salvelinus namaycush (Walbaum, 1792)) in a small subarctic lake to investigate depth and temperature occupancy, and vertical activity across seasons (summer, fall, and winter), diel ...

Ecdysteroids: A novel class of anabolic agents? [PDF]

, 2015
Increasing numbers of dietary supplements with ecdysteroids are marketed as “natural anabolic agents”. Results of recent studies suggested that their anabolic effect is mediated by estrogen receptor (ER) binding. Within this study the anabolic potency of

Temporal resource partitioning mediates vertebrate coexistence at carcasses: The role of competitive and facilitative interactions

Basic and Applied Ecology, 2022
Unravelling how biodiversity is maintained despite species competition for shared resources has been a central question in community ecology, and is gaining relevance amidst the current biodiversity crisis.

A small catalytic RNA motif with Diels-Alderase activity

Chemistry & Biology, 1999
The 'RNA world' hypothesis requires that RNA be able to catalyze a wide variety of chemical reactions. In vitro selection from combinatorial RNA libraries has been used to identify several catalytic activities, most of which have resulted in a self-modification of RNA at one of its constituents.

Flexibility in the diel migratory schedule of an Arctic songbird despite robust 24‐h activity rhythms across the annual cycle

Journal of Avian Biology
Many birds schedule their activity to a specific phase of the diel (24‐h) light–dark cycle. Two notable exceptions are the nocturnal migration of many otherwise diurnal songbirds and the diverse activity patterns of birds during the continuous light ...

Diel activity patterns of a canopy-inhibiting beetle community (Coleoptera) in a Neotropical rainforest

Frontiers in Forests and Global Change
Diel activity is one main feature of animal‘s behavior and is often an intrinsic trait characterizing distinct taxonomic groups. Abiotic conditions such as temperature may influence the diel activity patterns of arthropod communities associated with a ...

Diving behaviour of whale sharks in relation to a predictable food pulse [PDF]

, 2005
We present diving data for four whale sharks in relation to a predictable food pulse (reef fish spawn) and an analysis of the longest continuous fine-resolution diving record for a planktivorous shark.
