Brood production increases when artificial heating is provided to colonies of stingless bees
(INT BEE RESEARCH ASSOC, 2011)
Although stingless bees are capable of maintaining their nest temperature within certain limits, brood production of several species declines or even completely stops during periods of low ambient temperature. In the present ...
Increased brood viability and longer lifespan of honeybees selected for propolis production
(Springer, 2014-03-01)
Propolis has been proposed to affect honeybee health. To test this hypothesis, we initially evaluated propolis production in 36 honeybee colonies. The three highest (HP) and three lowest propolis-producing (LP) colonies ...
Factors affecting the probability of double brooding by Southern House WrensFactores que afectan la probabilidad de doble puesta en Troglodytes aedon musculus
(Wiley, 2014-09)
Seasonal fecundity of birds is influenced by clutch sizes and the number of successful breeding attempts during a breeding season. As such, understanding the factors that determine the decision to initiate multiple broods ...
Reproduction and oxidative metabolism in the brooding sea star Anasterias antarctica (Lütken, 1957)
(Elsevier, 2015-01)
The oral-brooding sea star Anasterias antarctica is distributed on the coasts of South Patagonia and north of Antarctic Peninsula. This species is a potential predator of shellfish Mytilus chilensis, an important commercial ...
Effects of reproductive stage and temperature on rates of oxygen consumption in Paralithodes platypus (Decapoda: Anomura)
(Oxford University Press, 2010-07)
Paralithodes platypus is a large decapod that inhabits Alaskan and North Pacific waters. Females exhibit a biennial spawning cycle, requiring two years for production of fully mature oöcytes. We used respirometry and video ...
Influence of management and environmental factors on mating success of Africanized queen honey bees
(Int Bee Research Assoc, 1995-01-01)
Environmental factors and management techniques were evaluated in São Paulo, Brazil, for enhanced production of Africanized queen honey bees. Queens were reared by the Doolittle method; 12 breeder, 6 cell-builder, and 36 ...
Standard methods for fungal brood disease research = Métodos estándar para la investigación de enfermedades fúngicas de la cría
(Taylor & Francis, 2013)
Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and ...
Apitoxin harvest affects population development but not the hygienic behavior of African-derived honey bees
(2016-03-01)
The biological properties of apitoxin have prompted its production for use in human and animal health applications. However, the apitoxin harvest triggers a defense reaction in honeybee colonies, which includes the release ...
