Form and metabolic scaling in colonial animals.
Benthic colonial organisms exhibit a wide variation in size and shape and provide excellent model systems for testing the predictions of models that describe the scaling of metabolic rate with organism size. We tested the hypothesis that colony form will influence metabolic scaling and its derivatives by characterising metabolic and propagule production rates in three species of freshwater bryo...
متن کاملEvolutionary Determinants of Morphological Polymorphism in Colonial Animals.
Colonial animals commonly exhibit morphologically polymorphic modular units that are phenotypically distinct and specialize in specific functional tasks. But how and why these polymorphic modules have evolved is poorly understood. Across colonial invertebrates, there is wide variation in the degree of polymorphism, from none in colonial ascidians to extreme polymorphism in siphonophores, such a...
متن کاملTemperature effects on mass-scaling exponents in colonial animals: a manipulative test.
Body size and temperature are fundamental drivers of ecological processes because they determine metabolic rates at the individual level. Whether these drivers act independently on individual-level metabolic rates remains uncertain. Most studies of intraspecific scaling of unitary organisms must rely on preexisting differences in size to examine its relationship with metabolic rate, thereby pot...
متن کاملColonial and post-colonial aspects of Australian identity.
Since the 1988 Bicentennial and the 2001 centenary of federation celebrations colonial images have flourished in Australia, highlighting the roles of convicts and free settlers during early colonization. Old sites, such as Port Arthur have been re-invigorated, and in 2004 Tasmanians celebrated the bicentenary of 'white' settlement. However, social scientists have given little attention to the r...
متن کاملThe Case of Children’s Literature: colonial or anti-colonial?
Since Jacqueline Rose published The Case of Peter Pan in 1984, scholars in the field of children’s literature have taken up a rhetorical stance which treats child readers as colonised, and children’s books as a colonising site. This article takes issue with Rose’s rhetoric of colonisation and its deployment by scholars, arguing that it is tainted by logical and ethical flaws. Rather, children’s...
