The impacts of biological invasions
Biological Reviews, EarlyView.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Environmental heterogeneity shapes physiological traits in tropical direct‐developing frogs
Ecology and Evolution, 2021 Tropical ectotherm species tend to have narrower physiological limits than species from temperate areas. As a consequence, tropical species are considered highly vulnerable to climate change since minor temperature increases can push them beyond their ...

Gene expression clines reveal local adaptation and associated trade-offs at a continental scale [PDF]
, 2016 Local adaptation, where fitness in one environment comes at a cost in another, should lead to spatial variation in trade-offs between life history traits and may be critical for population persistence.

Ectotherms Follow the Converse to Bergmann's Rule [PDF]
Evolution, 1997 In a recent paper, Van Voorhies (1996) suggested that Bergmann size clines in ectotherms might result from developmental processes that cause cells to grow larger at lower temperatures. Van Voorhies (1996) found that when Caenorhabditis elegans was grown at cool temperatures cell sizes were larger than control groups reared in a warmer environment, and

Special Challenges in PET Imaging of Ectothermic Vertebrates
Seminars in Nuclear Medicine, 2023 The bulk of biomedical positron emission tomography (PET)-scanning experiments are performed on mammals (ie, rodents, pigs, and dogs), and the technique is only infrequently applied to answer research questions in ectothermic vertebrates such as fish, amphibians, and reptiles.

Journal of Animal Ecology, 2019 1.Thermal performance curves (TPCs) have been estimated in multiple ectotherm species to understand their thermal plasticity and adaptation and to predict the effect of global warming.

Biological Reviews, EarlyView.ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

O-GlcNAcase:promiscuous hexosaminidase or key regulator of O-GlcNAc signalling? [PDF]
, 2014 O-GlcNAc signaling is regulated by an opposing pair of enzymes: O-GlcNAc transferase installs and O-GlcNAcase (OGA) removes the modification from proteins.

Biological Reviews, EarlyView.ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

The Case of Dinosaur Metabolism [PDF]
, 2017 In lieu of an abstract, here is the article\u27s first paragraph: To learn the critical skill of scientific argumentation, students need learning experiences that involve constructing evidence-based explanations.
