invasive species
- Acclimatization in the physiological performance of an introduced ectotherm
Summary: Introduced species use acclimatization to maintain high performance year round; therefore, phenotypic flexibility likely shapes the fundamental niche of both introduced and native species.
- Mitochondrial thermo-sensitivity in invasive and native freshwater mussels
Summary: Contrary to previous beliefs, invasive aquatic ectotherms do not always possess more thermo-tolerant mitochondria than their endemic counterparts.
- An appetite for invasion: digestive physiology, thermal performance and food intake in lionfish (Pterois spp.)
Editors' Choice: The relationship between digestive physiology and energetic physiology may play an important role in invasive species' success, demonstrated in invasive lionfish (Pterois spp.) in the context of a warming ocean.
- Variable vision in variable environments: the visual system of an invasive cichlid (Cichla monoculus) in Lake Gatun, Panama
Summary: Examination of the visual system plasticity of the peacock bass, Cichla monoculus, shows that this species adapts to a changing environment by alternating the use of chromophores A1 and A2, and through differential gene expression in the retina.
- Population history with invasive predators predicts innate immune function response to early-life glucocorticoid exposure in lizards
Summary: Historical, population-level exposure to invasive predatory fire ants (and associated stress) affects the immune consequences of early-life exposure to a stress-relevant hormone.
- Underlying mechanisms and ecological context of variation in exploratory behavior of the Argentine ant, Linepithema humile
Summary: Exploratory behavior in the Argentine ant is persistent and linked to the expression of the foraging gene. Workers outside the nest are more exploratory than those inside.
- Rapid adaptive response to a Mediterranean environment reduces phenotypic mismatch in a recent amphibian invader
Highlighted Article: The integration of field and laboratory experiments shows that a recent amphibian invader reduces phenotypic mismatch with the novel environment through physiological and behavioural responses across an unusually short time scale.
