Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

SPERMATOGONIES ET SPERMATOCYTES FLAGELLÉS CHEZ POECILIA RETICULATA (TÉLÉOSTÉENS CYPRINODONTIFORMES) [PDF]
La présence d'un flagelle sur des spermatogonies et spermatocytes et de 2 flagelles sur des spermatides est décrite chez le Guppy (Poecilia reticulata). Les flagelles présents sur les gonies et spermatocytes sont plus courts que ceux des spermatides et débouchent directement hors des cellules. Le mode de formation des flagelles est discuté.

Evidence for inbreeding depression in a species with limited opportunity for maternal effects [PDF]
It is often assumed that mating with close relatives reduces offspring fitness. In such cases, reduced offspring fitness may arise from inbreeding depression (i.e., genetic effects of elevated homozygosity) or from post-mating maternal investment.

Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Sperm storage by males causes changes in sperm phenotype and influences the reproductive fitness of males and their sons [PDF]
Recent studies suggest that environmentally induced effects on sperm phenotype can influence offspring phenotype beyond the classic Mendelian inheritance mechanism.

Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Female preference for blue in Japan blue guppies (Poecilia reticulata) [PDF]
Guppies (Poecilia reticulata) are widely used as a model species in mate choice studies. Although native to South America, guppies have been introduced to natural water bodies in disparate regions of the globe.
