Biodiversity and body size are linked across metazoans.
Body size variation across the Metazoa is immense, encompassing 17 orders of magnitude in biovolume. Factors driving this extreme diversification in size and the consequences of size variation for biological processes remain poorly resolved. Species diversity is invoked as both a predictor and a result of size variation, and theory predicts a strong correlation between the two. However, evidenc...
متن کاملExceptional body size-extinction risk relations shed new light on the freshwater biodiversity crisis.
In PNAS, Ripple et al. (1) show that the smallest species of reptiles, amphibians, and bony fishes suffer unusually high extinction risks given what we know about general body size–extinction risk relationships (2). The results of this study have important implications, considering that most studies exploring the communityor ecosystem-level consequences of nonrandom biodiversity loss focus on t...
متن کاملMorphometric Traits and Correlation between Body Weight and Body Size Traits in Isa Brown and IlorinEcotype Chickens
Data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin Isa Brown and Ilorin ecotypechickens. The studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...
متن کاملEcology. Coral reef biodiversity--habitat size matters.
Coral reefs are the most diverse of all marine ecosystems (1), with estimates of reef species ranging from 600,000 to more than 9 million species worldwide (2, 3). This biodiversity is most pronounced in the western Pacific and Indian Oceans (1, 4), but decreases with increasing distance from the Indo-Australian archipelago. For example, reefs in the central Indo-Pacific have more than 10 times...
