Extrapair paternity in two populations of the socially monogamous thorn-tailed rayadito aphrastura spinicauda (Passeriformes: Furnariidae)
(John Wiley and Sons Ltd, 2020-11)
Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is cur-rently lacking for most tropical and subtropical taxa. ...
Effect of eCG in a short-term synchronization treatment on ovarian status, estrus synchrony, and ovulation in dairy goats managed under tropical conditions
(Springer, 2021-06-01)
The aim of this study was to assess the need of using eCG on short-term estrus synchronization protocol in nulliparous (NUL) and multiparous (MULT) dairy goats during the breeding season. Alpine (n = 20), Nubian (n = 20), ...
Extrapair paternity in two populations of the socially monogamous Thorn-tailed Rayadito Aphrastura spinicauda (Passeriformes: Furnariidae)
(John Wiley and Sons Ltd, 2020-11)
Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
Clock gene variation in Tachycineta swallows
(Wiley, 2012-01)
Many animals use photoperiod cues to synchronize reproduction with environmental conditions and thereby improve their reproductive success. The circadian clock, which creates endogenous behavioral and physiological rhythms ...
Spatial and temporal variation in breeding parameters of two south‐temperate populations of House WrensVariación espacial y temporal de los parámetros reproductivos de dos poblaciones de Troglodytes aedon bonariae del sur templado
(Wiley, 2020-01)
Studies of variation in breeding parameters are often based on temporal analyses of a singlepopulation. However, to differentiate between the effects of regional and local factors, neighboring populations withlimited ...
Genetic mating system, population genetics and effective size of Saffron Finches breeding in southern South America
(Springer, 2019-08)
Thraupidae (Tanagers and allies) show a remarkable array of behaviors, ecologies, morphologies and plumage colors, offering a great opportunity to investigate the evolution of avian mating strategies. We characterize the ...
Technology for field sowing of somatic embryos or sinthetic seeds
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1989)
The document refers to research activities in the field of crop production, especifically, studies in vitro techniques related to synthetic seed technology, systems to regenerate plants from transformed cells of sweet ...
Genetic diversity and reproductive biology of the dioecious and epiphytic bromeliad Aechmea mariae-reginae (Bromeliaceae) in Costa Rica: implications for its conservation
(2019)
Ecological traits and pollination mode associated with dioecious sexual expression in plants are likely to influence
their reproductive success and levels of genetic diversity. Dioecy is an uncommon condition in Bromeliaceae. ...
