Factors affecting brood patch development in Magellanic Penguins Spheniscus magellanicus
(Polish Academy of Sciences. Museum and Institute of Zoology, 2016-05)
Brood patches allow the transfer of heat to eggs for their successful embryonic development, and in many species determine egg temperature during incubation. We investigated brood patch development of Magellanic Penguins ...
Brooding in Psolus patagonicus (Echinodermata: Holothuroidea) from Argentina, SW Atlantic Ocean
(Springer, 2010-02)
The mode, season, and time of brooding, egg diameter, egg number per brood, and the characteristics of newly released juveniles of Psolus patagonicus were investigated off Mar del Plata, Buenos Aires, Argentina, between ...
Fast weight recovery, metabolic rate adjustment and gene-expression regulation define responses of cold-stressed honey bee brood
(Pergamon-Elsevier Science Ltd, 2021-01)
In temperate climates, low ambient temperatures in late winter and in spring can result in cold stress conditions in brood areas of weakened honey bee colonies, leading to increased levels of developmental interruptions ...
Effect of natural brood size variability on growth and survival of thornbird nestlings
(Wiley Blackwell Publishing, Inc, 2016-09)
For many bird species, brood size is a highly variable trait. Several aspects of the development and survival of nestlings are affected by brood size. Most scientific evidence comes from brood manipulation experiments, and ...
Notes on brood morphology and development of the neotropical eusocial wasp mischocyttarus cerberus (Hymenoptera, Vespidae, Polistinae)
(2020-06-01)
Mischocyttarus cerberus stands out as the most investigated species of eusocial paper wasp, in Brazil. While the adult characteristics were relatively well reported in the earlier studies, very meager information was ...
Unusual modes of oogenesis and brooding in bivalves: the case of Gaimardia trapesina (Mollusca: Gaimardiidae)
(Wiley Blackwell Publishing, Inc, 2009-08)
I describe an unusual case of follicular oogenesis in a bivalve, Gaimardia trapesina, a common marine bivalve from the Magellan Region and adjacent Sub-Antarctic waters, whose members brood their developing larvae. The ...
Delayed start of full incubation is related to a delayed brood patch development in Magellanic penguins
(Taylor & Francis Ltd, 2016-05)
Capsule: Most bird species start full incubation before the clutch is complete, others long after laying the last egg, gradually increasing the incubation temperature as incubation progresses, as is the case in Magellanic ...
Aboral brooding in the deep water sea star Ctenodiscus australis Lütken, 1871 (Asteroidea) from the Southwestern Atlantic
(Pergamon-Elsevier Science Ltd, 2017-05)
Different stages of development and growth were found in the dorsal surface under the paxillae of Ctenodiscus australis. The maximum number of broods found per specimen was 73 and in some cases different stages were observed ...
Spatial patterns in the brood combs of Nannotrigona testaceicornis (Hymenoptera: Meliponinae): male clusters
(FUNPEC-EDITORA, 2009)
Genetic models of sex and caste determination in eusocial stingless bees suggest specific patterns of male, worker and gyne cell distribution in the brood comb. Conflict between queen and laying workers over male parentage ...
Brood care in Brachyuran crabs: the effect of oxygen provision on reproductive costs
(Sociedad de Biología de Chile, 2003)
