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 ...
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 ...
Biology of the subtropical sac-spawning euphausiid Nyctiphanes simplex in the northwestern seas of Mexico: Vertical and horizontal distribution patterns and seasonal variability of brood size
(Deep-Sea Research Part II: Topical Studies in Oceanography, 2010)
Vertical and horizontal distributions of the subtropical euphausiid juvenile and adult Nyctiphanes simplex were mapped from samples collected during winter and summer 2007 in the Gulf of California, Mexico. During winter, ...
Reproductive features in the sea cucumber Pentactella perrieri (Ekman, 1927) (Holothuroidea: Cucumariidae): a brooding hermaphrodite species from the southwestern Atlantic Ocean
(Springer, 2020-09)
Cucumariidae (Echinodermata: Holothuroidea) is a family of sea cucumbers known for displaying different reproductive strategies, including brooding and hermaphroditism. These reproductive strategies of marine invertebrates ...
Strategic egg destruction by brood-parasitic cowbirds?
(Elsevier, 2014-06)
Obligate avian brood parasites do not provide direct care to their young but can indirectly increase their offspring's success in host nests. One way in which parasitic cowbirds (Molothrus sp.) could achieve this is through ...
The relationship of telomere length to baseline corticosterone levels in nestlings of an altricial passerine bird in natural populations
(Biomed Central, 2016)
Background: Environmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage. Modification of telomere length, as a result of adversity faced early in life, can ...
What is the stimulus for the excavation of fungus chamber in leaf-cutting ants?
(Springer, 2015-02-01)
This study investigated the stimulus for the excavation of fungus chamber by leaf-cutting ants (Atta sexdens rubropilosa) during nest building. Thus, it was hypothesized that the fungus garden or the brood is a stimulus ...
The effects of temperature and oxygen availability on intracapsular development of Acanthina monodon (Gastropoda: Muricidae)
(Sociedad de Biología de Chile, 2006)
High fishing intensity reduces females' sperm reserve and brood fecundity in a eubrachyuran crab subject to sex- and size-biased harvest
(2017)
Size-selective male fisheries may result in sperm limitation whereby the number of sperm is insufficient to fertilize all oocytes produced by females. In eubrachyuran crabs, females have seminal receptacles for sperm storage ...
