Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Comparative evaluation of Doolittle, Cupkit and Karl Jenter techniques for rearing Apis mellifera Linnaeus queen bees during breeding season [PDF]

open access: yes, 2017
Comparative evaluation of Doolittle, Karl Jenter and Cupkit techniques of Apis mellifera Linnaeus queen bee rearing was done during spring (mid February- mid April 2013) breeding season. The highest acceptance of cell cups (66.00 %), queen cells raising (

Ctenophore population recruits entirely through larval reproduction in the central Baltic Sea [PDF]

open access: yes, 2012
The comb jelly Mertensia ovum, widely distributed in Arctic regions, has recently been discovered in the northern Baltic Sea. We show that M. ovum also exists in the central Baltic but that the population consists solely of small-sized larvae (less than ...

Carbon content of Mnemiopsis leidyi eggs and specific egg production rates in northern Europe [PDF]

open access: yes, 2014
The comb jelly Mnemiopsis leidyi is considered to be a successful invasive species, partly due to its high reproduction potential. However, due to the absence of direct carbon measurements of eggs, specific reproduction rates remain uncertain.

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]

open access: yes, 2012
During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

Inertia-driven flow symmetry breaking by oscillating plates

open access: yesAIP Advances, 2019
While cilia are generally found in viscosity-dominated regimes, those of a comb jelly, the longest motile cilia in nature, are used for propulsion and feeding in inertia-dominated flows.

Polymer‐in‐Cage Strategy for Pore Tuning of High‐Aspect Ratio ZIF Nanoplate: Toward Sub‐Micrometer‐Thick Large Area CO2 Separation Membranes

open access: yesAdvanced Science, EarlyView.
A “polymer‐in‐cage” strategy transforms a zinc‐acrylate copolymer into an active pore‐modulating agent for ZIF‐8 nanoplates. The polymer actively tunes the MOF's pore structure by anchoring within its windows, while the nanoplates create tortuous pathways.
