Diel feeding pattern of whiting in the North Sea [PDF]

open access: yesMarine Ecology Progress Series, 2003
Though numerous studies have analysed the feeding periodicity of North Sea gadoids, no general diel pattern has been found. The lack of agreement between studies may be related to differences in prey composition and behaviour, but it has not been attempted to link the diel intake pattern directly to intake of individual prey.

The Use of an Anthrone Reagent to Detect Sugar Meals and Their Persistence in the Mosquito \u3ci\u3eAedes Triseriatus\u3c/i\u3e (Diptera: Culicidae) [PDF]

open access: yes, 2017
Adults of Aedes triseriatus were fed water, blood, and 10% pure and mixed solutions of glucose, fructose and sucrose. Adults were tested for fructose by the cold-anthrone test 0, 1, 4, 12, and 24 h after feeding. Water-fed males and females and blood-fed

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

open access: yesAngewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Protistal Grazers Increase Grazing on Unicellular Cyanobacteria Diazotroph at Night

open access: yesFrontiers in Marine Science, 2020
In this study, we have for the first time analyzed diel microzooplankton grazing selectivity on unicellular cyanobacterial diazotroph (i.e., Crocosphaera watsonii WH8501) and non-diazotrophic unicellular microalga (i.e., Chlorella autotrophica).

Small-scale distribution of juvenile gadoids in shallow inshore waters; what role does maerl play? [PDF]

open access: yes, 2004
The indirect effects of demersal fisheries, such as habitat degradation, are currently thought to be impacting gadoid stocks. Maerl fulfils nursery area prerequisites for several invertebrate species, so its role in similar ecosystem service provision ...

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference [PDF]

open access: yes, 2006
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

Food selectivity and diet switch can explain the slow feeding of herbivorous coral-reef fishes during the morning. [PDF]

open access: yesPLoS ONE, 2013
Most herbivorous coral-reef fishes feed slower in the morning than in the afternoon. Given the typical scarcity of algae in coral reefs, this behavior seems maladaptive.

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

open access: yes, 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.

Diel feeding rhythms in marine protistan grazers

open access: yes, 2020
[CAT] Els pastors protistes són un component clau de les xarxes alimentàries planctòniques marines. Aquests protistes marins constitueix el principal consumidor de la producció primària pelàgica en els oceans i presenta, per tant, un paper crucial en els cicles biogeoquímics marins com intermediaris fonamentals en els fluxos d'energia i de massa des ...

Effects of Short-Duration and Diel-Cycling Hypoxia on Predation of Mussels and Oysters in Two Tributaries of the Chesapeake Bay

open access: yesDiversity, 2020
Although the effects of persistent hypoxia have been well established, few studies have explored the community-level effects of short-duration and diel-cycling hypoxia, for example on predator−prey interactions.
