How do forage availability and climate control sheep reproductive performance?. An analysis based on artificial neural networks and remotely sensed data
(Elsevier Science, 2008-09)
Environmental variability affects life history and fitness of both animal and plant species. For herbivores in particular, climate can have strong direct and indirect effects on demography, which tend to exacerbate in arid ...
Fire frequency effects on cleistogamy expression and progeny performance in cologania broussonetii
(Wiley Blackwell Publishing, Inc, 2020-11-12)
Increased fire frequency usually erodes microenvironmental conditions causing a drastic limitation of edaphic resources. Thus, the production of permanently closed-small flowers (cleistogamous, CL) should increase in sites ...
Stigmas arrangement, reproductive system, and maternal reproductive success in two species of Stigmaphyllon (Malpighiaceae): does pollinator size matter?
(Springer, 2021-09)
Most species of Neotropical Malpighiaceae are pollinated by oil-collecting bees of diverse sizes, but the effect of pollinator size on their reproductive success has still not been addressed in the literature. We performed ...
Phenotypic and genetic analysis of reproductive traits in horse populations with different breeding purposes
(Cambridge University Press, 2020-02-06)
Reproductive traits have a major influence on the economic effectiveness of horse breeding. However, there is little information available. We evaluated the use of reproductive traits as selection criteria in official ...
Dynamics of energy reserves and the cost of reproduction in female and male fiddler crabs
(Elsevier Gmbh, 2018-02)
The physiological costs of reproduction can be measured as the energy allocated to reproductive activities. In fiddler crabs, females allocate energy to vitellogenesis and brooding, whereas males perform expensive courtship ...
Kleptoparasitism during courtship in Sterna hirundo and its relationship with female reproductive performance
(Springer, 2010-06-15)
Kleptoparasitism is a well-known foraging tactic used opportunistically by many seabird species. However, little is known about this behaviour during the early stages of the breeding cycle and its effects on breeding ...
Prevalence of Clinical Endometritis and its Impact on Reproductive Performance in Grazing Dairy Cattle in Argentina
(Wiley Blackwell Publishing, Inc, 2011-06)
The objective of this study was to evaluate the prevalence of clinical endometritis and its impact on reproductive performance in grazing dairy cattle in Argentina to compare data with previous reports from herds kept in ...
Impaired reproductive function in equines: From genetics to genomics
(Multidisciplinary Digital Publishing Institute, 2021-02-03)
Fertility is one of the key factors in the economic and productive success of the equine industry. Despite this, studies on the genetic causes affecting reproductive performance are scarce, especially in mares, where the ...
Do female reproductive stage and phenotype influence thermal requirements in an oviparous lizard?
(Pergamon-Elsevier Science Ltd, 2018-01)
Reproduction is an energetically costly activity that can alter thermal requirements in Squamata. This phenomenon has been largely studied in many viviparous species; however, little is known about the role of oviparous ...
Epidemiological Description of Cystic Ovarian Disease in Argentine Dairy Herds: Risk Factors and Effects on the Reproductive Performance of Lactating Cows
(Wiley, 2014-12)
To describe the epidemiology of cystic ovarian disease (COD), to find possible risk factors associated with the incidence of cysts and to analyse the impact of COD on the reproductive performance of dairy cows, databases ...
