Pheromones in entomopathogenic nematodes: effects on dispersal and reproductive behaviours
… in coordinating a variety of important behaviours in entomopathogenic nematodes, particularly Steinernema, both as primers (longer term developmental effects) and releasers (short term behavioural effects). I investigate both sex pheromones and chemical signals produced by and affecting …

Life history of marine threespine stickleback in Oyster Lagoon, British Columbia
… Columbia. Until this study, the life history and reproductive behaviours of marine population along the Pacific coast of North America were unknown. Data was collected from September 1990 to August 1992 at Oyster Lagoon, Pender Harbour, British Columbia. Morphology, migration and growth, …

The Association Between Early Menarche and Preterm Birth
… healthcare outcomes throughout a females reproductive life is an important area of research that is in need of more investigation. Specifically, there is a limited body of evidence available that explores the association between early reproductive behaviours and future pregnancy outcomes. …

The neurobiology of central dopamine and progesterone in the reproductive cycle of the ring dove (Streptopelia risoria)
… of neural and hormonal determinants of reproductive behaviours. Studies were undertaken to investigate the role of dopamine and progesterone in the expression of sexually differentiated patterns of behaviours during the breeding cycle, and provide the first mapping of tyrosine …

The behavioural function of pheromones in crayfish
… crayfish was found to coincide with aggressive behaviours rather than reproductive behaviours. Female urine release was essential for initiating mating, with males detecting female receptivity by spying on hormones and metabolites released with threat signals. Physiological indicators of …

Individual reproductive strategies in the dusky warbler (Phylloscopus fuscatus)
… the study focuses on individual variation in the reproductive behaviours of both females and males. The mating system of this population is characterised by facultative polygyny (17 per cent of the males mated with more than one female), and by an outstandingly high rate of extra-pair paternity …

Population Ecology of Rhabdomys dilectus dilectus in the Western Soutpansberg Mountains
… population dynamics, habitat preferences, and reproductive patterns across three distinct ecological sites: Wetland, Wilderness Camp, and Patches. Specifically, it aimed to assess how environmental variables, such as rainfall and habitat characteristics, influence the distribution, abundance, …

Unravelling the ecological trade-offs in behavioural and physiological sexual traits
… how the variation in these factors may impact reproductive behaviours and fitness outcomes. Nutritional restriction lowers individual quality, and so should also increase the expression of trade-offs between traits, due to their impaired energy reserves. I found no clear directional response …
