Abstract

Larvae from many marine coastal species deploy ecological strategies that promote their arrival to geographically close or distant populations. Some larvae adjust their vertical positions in response to the tidal cycle, which, in combination with coastal features, helps keep them relatively close to their natal population instead of being advected offshore (retention-oriented larvae). However, a few of these larvae are transported away from their natal population and spread further afield. In this study, we aimed to better understand the environmental mechanisms that influence the export of retention-oriented larvae by modelling the transport of tidal larvae and using a species distribution model to predict that export rate. The larval transport model was parametrised with ecological data about the Pacific oyster Magallana gigas and tidal larval behaviour from 2 Irish coastal regions. The simulated dispersal of retention-oriented larvae showed that 55-60% of larvae were exported from the 2 regions. This export rate decreased to below 40% if the release occurred in protected and shallow coastal areas. The exportation of larvae occurred relatively early in a larva’s simulated pelagic life (when the larva began to have an active behaviour). When export rate was associated with the coastal features in the 2 Irish regions, wave exposure at the release sites was an important predictor for low (below 20%) and high (above 90%) export rates. The study has implications for the management of coastal grounds since export rates of retention-oriented larvae can be predicted based on knowledge of local hydrodynamics. Our approach could be applied to predict the export rate of other coastal larvae with retention-oriented behaviour

14. Explaining the geographic distributions of sexual and asexual populations

Abstract

A mathematical model of habitat stretching from south to north in the Northern Hemisphere was constructed to examined the geographic distributions of sexual and asexual populations. The model supports the idea that a single basic process may account for geographic parthenogenesis, and that the process involves the movement of individuals from areas where they are well adapted to areas where they are poorly adapted.

Abstract

Demographic analysis methodologies which consider the transient dynamics of a population promise to be highly relevant for population conservation and management, but the present methods of analysis are still in the early stages of being developed. The methods require a knowledge of a population’s initial stage-structure, and produce output which is complicated, and difficult to describe succinctly. This paper investigates whether the initial stage-structure is always required in order to obtain reliable information on the transient population dynamics. The paper also presents new methods for succinctly presenting the data from these near-term demographic analyses. The work of Fox and Gurevitch [Am. Naturalist 156 (2000) 242] is extended by deriving an analytical formula which decomposes their near-term sensitivity into two components: one which does not require the populations initial stage-structure to be measured, and one which does. This decomposition is used to estimate the sensitivity of the analysis to the initial population stage structure, without a knowledge of the population structure. The near-term sensitivity analysis is extended to look at several measures for the near-term sensitivity of population growth rate. These new measures allow the information contained in the analysis to be condensed, and for a comparison to be made between near-term and asymptotic sensitivity analyses. The methods are demonstrated by analysing empirical data on the cactus Coryphantha robbinsorum. [Copyright &y& Elsevier]
