Observations on nesting activity, life cycle, and brood ball morphometry of the Bordered Dung Beetle Oniticellus cinctus (Fabricius, 1775) (Coleoptera: Scarabaeidae) under laboratory conditions

Journal of Threatened Taxa, 2019
The nesting activity, life cycle, and brood ball morphometry of the dung beetle Oniticellus cinctus (Fabricius, 1775) (Coleoptera: Scarabaeidae) were studied under laboratory conditions for the first time in India.

Temporary Communal Brooding in Northern Bobwhite and Scaled Quail Broods

Western North American Naturalist, 2016
Abstract. Communal brooding, which can occur as a result of brood amalgamation or communal parental care, is a common alternative brooding strategy observed in many precocial bird species. Although the occurrence of long-term communal brooding has been documented in numerous waterfowl species, and to a lesser extent in gallinaceous species, the ...

Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

Advanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

Use Supplementary Feedings on Bee Colony Development and Venom Production

Scientific Papers Animal Science and Biotechnologies
The paper presents the influence of the use of supplementary feedings on the development of bee colonies and venom production. We evaluated the venom production during harvests of rapeseed, acacia and sunflower. The research was carried out in the apiary

Considerations about effective dissemination of improved fish strains [PDF]

, 2012
Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health issues of such production systems,

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Drone and Worker Brood Was Unexpectedly Well Heated Both in Standard-Cell and Small-Cell Comb Colonies

Journal of Apicultural Science, 2019
Temperatures of worker- and drone-brood rearing in various hive locations were compared in both colonies kept on small-cell combs (4.90 mm) (SMC) and standard-cell combs (5.50 mm) (STC) in two seasons.

Boosting the Energy Density of “Anode‐Free” Lithium Metal Batteries via Electrospun Polymeric Scaffolds

Advanced Functional Materials, EarlyView.
While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

E-B-ocimene and brood cannibalism: Interplay between a honey bee larval pheromone and brood regulation in summer dearth colonies.

PLoS ONE
Honey bees balance colony populations against available food resources by adjusting brood rearing during nutritionally-stressed periods. Workers limit colony populations primarily through brood cannibalism of eggs and young larvae but often resume brood ...
