It is lonely at the front: contrasting evolutionary trajectories in male and female invaders [PDF]
Royal Society Open Science, 2016 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.

Ecology and Evolution, Volume 14, Issue 12, December 2024.We show that large floodplain monitors reach sexual maturity surprisingly rapidly, and females rarely live for more than 2 years. This fast life history requires novel reproductive strategies and high feeding rates, favouring the evolution of “risky” tactics such as consuming novel prey items (such as invasive toxic cane toads).

A Review of Theory: Comparing Invasion Ecology and Climate Change‐Induced Range Shifting
Global Change Biology, Volume 30, Issue 12, December 2024.We argue that scientists studying either non‐native invasions or climate change‐induced range shifting are interested in the same underlying mechanistic questions: (1) What species traits enable survival in a new location? and (2) Which recipient ecosystems are likely to support a newly arrived species?

Temperature-dependent tonic contraction of smooth muscle in Antarctic fishes Notothenia neglecta and Chaenocephalus aceratus - Role of calcium ions and responses to acetylcholine [PDF]
, 2000 The isolated intestinal smooth muscle of Antarctic fishes Notothenia neglecta and the icefish Chaenocephalus aceratus displayed a sustained tonic contraction depending upon the temperature of the nutritive bath.

Pheromones can cull an invasive amphibian without releasing survivors from intraspecific competition
Ecosphere, 2019 Attempts to cull an invasive species often create a paradoxical situation, whereby the consequent reduction in invader densities frees the survivors from intraspecific competition—and hence, increases the viability of those survivors.

Geoarchaeology, Volume 39, Issue 3, Page 320-334, May/June 2024.Abstract The Archaeological Site of Panama Viejo (Panama) comprises a protected area of 28 km2 within present‐day Panama City, on America's Pacific coast. In 1519, the Spaniards founded the city of Panama Viejo to secure a natural port in an area inhabited by indigenous peoples since at least the eighth century CE.
