(Halifax, N.S. : Saint Mary's University, 2021)Sexual strategies theory indicates that humans can adopt short- and long-term mating strategies, producing sex- and strategy-specific mating behaviours due to asymmetries in obligate parental investment into children. ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Heat shock proteins (HSPs) are highly conserved and present in organisms under normal physiological conditions and function in protein folding, degradation and localization. HSPs are also synthesized in response to ...
-
(Halifax, N.S. : Saint Mary's University, 2018)The operational sex ratio is the number of fertilizable females to mature males in a population at a particular time. Variation in this ratio is often associated with change in behaviour during mating, including differences ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Sexual selection acts by favouring traits that give some individuals an advantage over competitors in acquiring mates and producing offspring, and more commonly acts on males due to their generally higher variability in ...
-
(Halifax, N.S. : Saint Mary's University, 2019)During mating, animals use both behavioural and morphological traits to compete for and attract mates. In some species, one of the sexes may exhibit nuptial colouration, a type of signal that is under sexual selection. ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Adaptation is a process that occurs through natural and sexual selection and can drive variation within species. By showing that certain sexual traits are inherited, I demonstrated that these traits can vary, at least in ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Operational sex ratio (OSR) is the ratio of sexually active males to fertilizable females in a population. The OSR can be used to predict variation in mating behaviours across different social contexts and is used to predict ...
-
(Halifax, N.S. : Saint Mary's University, 2020)Alewife (Alosa pseudoharengus) are an anadromous species of river herring that are found in the Atlantic Ocean, ranging from the coasts of North Carolina, USA to Newfoundland, Canada. Age-structured population models and ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Sexual selection can lead to the development of secondary sex traits and mating behaviours. Morphological and behavioural traits may increase individual reproductive success, however, under varying sexual selection types ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Fish normally live in salinities ranging from 0 ppt (freshwater) to ~35 ppt (seawater) but most fish can only inhabit fresh or saltwater making salinity a main factor in determining their distribution. While euryhaline ...
-
(Halifax, N.S. : Saint Mary's University, 2022-04-29)One of the defining characteristics in sexual dimorphism is that there are morphological differences between the sexes. Sexual selection favors traits that are advantageous for reproduction, usually acting on males due ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Examining population dynamics within fisheries science is an effective way to investigate the size and age structure of a given fish population, and to understand how that stock might change over time. Porbeagle sharks are ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Understanding life-history strategies is essential for developing a clear picture of how organisms have evolved and how they may perform under future conditions. Bet-hedging is a life-history strategy that allows populations ...
