Interplay between fecundity, sexual and growth selection on the spring phenology of European beech (Fagus sylvatica L.).

Peer Community Journal
Background: Plant phenological traits such as the timing of budburst or flowering can evolve on ecological timescales through response to fecundity and viability selection.

Integrated analysis of microRNA and mRNA interactions regulating fecundity in the ovaries of two distinct sheep breeds

BMC Genomics
Sheep production is vital to the global agricultural economy, particularly for meat and wool. However, fertility varies significantly among breeds, influenced by genetics, nutrition, and environment.

Annual Fecundity of European Anchovy: A Case Study in the North Aegean Sea (Eastern Mediterranean)

Fishes
Egg production estimates are key indicators of stock reproductive potential. In indeterminate spawners, annual fecundity cannot be estimated prior to the spawning season and, instead, requires quantification of batch fecundity and spawning frequency ...

Biological parameters of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) assayed with Bacillus thuringiensis berliner

Scientia Agricola, 2005
The bacterium Bacillus thuringiensis (Bt) is a promising control agent of Spodoptera frugiperda (J.E. Smith). Besides the lethal effect on hosts, the entomopathogen may cause physiological alterations that hinder insects' feeding intake and reproduction.

Effects of blood meal source and seasonality on reproductive traits of Culex quinquefasciatus (Diptera: Culicidae)

eLife
Host selection by mosquitoes is a keystone in understanding viral circulation and predicting future infection outbreaks. Culex mosquitoes frequently feed on birds during spring and early summer, shifting into mammals towards late summer and autumn.
