Adrenocortical Stress Response

Continued range expansion into physiologically challenging environments requires invasive species to maintain adaptive phenotypic performance. The adrenocortical stress response, governed in part by glucocorticoid hormones, influences physiological and behavioural responses of vertebrates to environmental stressors. However, any adaptive role of this response in invasive populations that are expanding into extreme environments is currently unclear. We experimentally manipulated the adrenocortical stress response of invasive cane toads ( Rhinella marina ) to investigate its effect on phenotypic performance and fitness at the species' range front in the Tanami Desert, Australia. Here, toads are vulnerable to overheating and dehydration during the annual hot–dry season and display elevated plasma corticosterone levels indicative of severe environmental stress. By comparing unmanipulated control toads with toads whose adrenocortical stress response was manipulated to increase acute physiological stress responsiveness, we found that control toads had significantly reduced daily evaporative water loss and higher survival relative to the experimental animals. The adrenocortical stress response hence appears essential in facilitating complex phenotypic performance and setting fitness trajectories of individuals from invasive species during range expansion.

Abstract Traits that aid in the invasion process should exhibit a gradient across the expansion range in response to changing selection pressures. Aggression has been repeatedly associated with invasion success in many taxa, as it may help invaders to wrestle the resources from other species which enhances their success in a novel environment. However, aggression primarily allows individuals to overcome conspecific rivals, providing advantages in competition over resources. Agonistic prowess could therefore increase fitness at both ends of the expansion gradient. Here we review the role of aggression in range expansion of invasive species, and its potential role as a driver of range expansion. We analyze how these different mechanisms could affect trait variation in expanding and invasive populations. Specifically, we look at how aggression could help dilate the edges of a population through niche competition, as well as lead to exclusion from the center (i.e. areas of high population density) by the conspe-cifics. Both of these processes will result in a characteristic spatial distribution of phenotypes related to aggression that could provide insights into the ecological pressures and dynamics of expanding populations, potentially providing clues to their success as niche competitors and invasive species.

Lakes And Reservoirs

AbstractA survey of lakes and reservoirs during the spring and summer of 2012 found that five species of calanoid copepods are invasive in the continental United States: Arctodiaptomus dorsalis (Marsh, 1907), Skistodiaptomus pallidus (Herrick, 1879), Eurytemora affinis (Poppe, 1880), Pseudodiaptomus forbesi (Poppe & Richard, 1890), and Sinocalanus doerri (Brehm, 1909). Two species are listed on the IUCN Red List of Threatened Species: Skistodiaptomus carolinensis (Yeatman, 1986) and S. sinuatus (Kincaid, 1953). Sample locations for the five invasive and two rare species are reported and compared to historical distributions. Results corroborate previous reports of range expansion for the five invasive species, indicating that these species have likely become well-established in regions into which they have recently expanded. New localities for the two rare taxa suggest a possible range expansion within the USA.
