It is lonely at the front: contrasting evolutionary trajectories in male and female invaders [PDF]
Invasive species often exhibit rapid evolutionary changes, and can provide powerful insights into the selective forces shaping phenotypic traits that influence dispersal rates and/or sexual interactions. Invasions also may modify sexual dimorphism.

Knocking on heaven's door : are novel invaders necessarily facing naive native species on islands ? [PDF]
The impact of alien predator species on insular native biota has often been attributed to island prey naivete (i.e. lack of, or inefficient, anti-predator behavior).

Stemming the tide: progress towards resolving the causes of decline and implementing management responses for the disappearing mammal fauna of northern Australia [PDF]
Introduction: Recent studies at sites in northern Australia have reported severe and rapid decline of several native mammal species, notwithstanding an environmental context (small human population size, limited habitat loss, substantial reservation ...

ABSTRACT In our rapidly changing world, evolution is likely to play an important role in facilitating the resilience of wildlife populations. The Sierra Nevada yellow‐legged frog (Rana sierrae) provides a rare example of recovery following severe declines caused by the amphibian chytrid fungus (Batrachochytrium dendrobatidis).

Abstract The American toad (Anaxyrus americanus) is a native insectivorous amphibian common in agricultural fields in eastern North America. Past research on this and related species suggests potential for positive or negative effects on pest populations, depending on the prevalence of intraguild predation.

Characterisation of major histocompatibility complex class I in the Australian cane toad, Rhinella marina. [PDF]
The Major Histocompatibility Complex (MHC) class I is a highly variable gene family that encodes cell-surface receptors vital for recognition of intracellular pathogens and initiation of immune responses.

Abstract While roads have well‐documented effects on wildlife movement, the impact of smaller non‐vehicle recreational trails typical of urban preserves is less thoroughly understood, particularly for small mammals. We used mark–recapture to identify movement of deer mice (Peromyscus maniculatus) across three broad (>2.5 m) recreational trails in small

Dispersal is a process of central importance for the ecological and evolutionary dynamics of populations and communities, because of its diverse consequences for gene flow and demography.

ABSTRACT Invasive species that undergo a founder event may experience a decline in genetic diversity yet still establish successful populations. A possible example is a population of the common wall lizard (Podarcis muralis) in Cincinnati, Ohio, USA, which was founded following an introduction in the 1950s of a small number of individuals from Europe ...

Congener diversity, topographic heterogeneity and human‐assisted dispersal predict spread rates of alien herpetofauna at a global scale [PDF]
Understanding the factors that determine rates of range expansion is not only crucial for developing risk assessment schemes and management strategies for invasive species, but also provides important insight into the ability of species to disperse in ...
