Temperature profoundly impacts both the phenotypes and distributions of organisms. These
thermal effects exert strong selective pressures on behaviour, physiology and life history …

The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Coincident with recent global warming, species have shifted their geographic distributions to
cooler environments, generally by moving along thermal axes to higher latitudes, higher …

Climate change is expected to increase the frequency of some climatic extremes,. These
may have drastic impacts on biodiversity,, particularly if meteorological thresholds are …

Random and subtle deviations from bilateral symmetry (fluctuating asymmetry) have long
been of interest to biologists who wish to study the susceptibility of organisms to changes in …

Summary 1 In insects, cuticular melanization and immune function are strongly dependent
on the quantity of dietary protein ingested. However, relatively little is known about the role …

From the outset multiple causes have been suggested for changes in melanic gene
frequency in the peppered moth Biston betularia and other industrial melanic moths. These …

Behavioral ecologists have long studied the role of coloration as a defense against natural
enemies. Recent reviews of defensive coloration have emphasized that these visual signals …

Abstract Flip through The Pictorial Guide to the Living Primates1 and you will notice a
striking yet generally underappreciated aspect of primate biology: primates are extremely …

Urbanization involves a cocktail of human‐induced rapid environmental changes and is
forecasted to gain further importance. Urban‐heat‐island effects result in increased …
