A molecular genetic time scale demonstrates Cretaceous origins and multiple diversification rate shifts within the order Galliformes (Aves).
The phylogeny of Galliformes (landfowl) has been studied extensively; however, the associated chronologies have been criticized recently due to misplaced or misidentified fossil calibrations. As a… Expand

Can sexual selection drive female life histories? A comparative study on Galliform birds
Sexual selection has been identified as a major evolutionary force shaping male life history traits but its impact on female life history evolution is less clear. Here we examine the impact of sexual… Expand

Digestive Organ Sizes and Enzyme Activities of Refueling Western Sandpipers (Calidris mauri): Contrasting Effects of Season and Age
We examined seasonal and age‐related variation in digestive organ sizes and enzyme activities in female western sandpipers (Calidris mauri) refueling at a coastal stopover site in southern British… Expand

Causes and consequences of post-growth age-dependent differences in small intestine size in a migratory sandpiper (Calidris mauri, Western Sandpiper)
Summary 1Calidris mauri Cabanis (Western Sandpiper) exhibits a pronounced post-growth age-dependent difference in small intestine size during southward migration, such that the later-migrating… Expand

On the evolution of omnivory in a community context
Omnivory is extremely common in animals, yet theory predicts that when given a choice of resources specialization should be favored over being generalist. The evolution of a feeding phenotype… Expand

Disproportionate bill length dimorphism and niche differentiation in wintering western sandpipers (Calidris mauri)
Western sandpipers (Calidris mauri (Cabanis, 1857)) exhibit slight female-biased sexual size dimorphism (5%) but disproportionate bill length dimorphism (15.9%). We test two predictions of the niche… Expand

Extreme Intraclutch Egg-Size Dimorphism in Eudyptes Penguins, an Evolutionary Response to Clutch-Size Maladaptation
Eudyptes penguins (six species) are uniquely characterized by a two-egg clutch with extreme intraclutch egg-size dimorphism (ESD): the first-laid A-egg is 17.5%–56.9% smaller than the B-egg. Although… Expand

Tissue Damage Precludes the Use of the Everted Sleeve Technique to Measure Nutrient Uptake in a Small Migratory Shorebird, the Western Sandpiper (Calidris mauri)
In vitro measurement of nutrient (e.g., glucose and proline) uptake rates across the brush border of the small intestine has played an integral role in the current understanding of the adaptive… Expand

Hereditary hyper-ACE-emia due to the Pro1199Leu mutation of somatic ACE as a potential pitfall in diagnosis: a first family outside Europe
Abstract Elevated plasma levels of angiotensin converting enzyme (ACE) are associated with granulomatous diseases. However, several families of autosomal dominant hyper-ACE-emia without disease… Expand

Optimising different types of biodiversity coverage of protected areas with a case study using Himalayan Galliformes
Abstract International targets have committed governments to expanding the global protected area (PA) network to 17% of the terrestrial surface by 2020. Optimising PA placement in the landscape is… Expand
