Geographical trends in body size are commonly interpreted in the framework of Bergmann's rule, which states that larger body sizes are found at higher latitudes. Here we demonstrate a negative association of body size with latitude among over-wintering warblers of the genus Phylloscopus as well as within a single species (Phylloscopus trochiloides) we were able to study in depth. We examine the role of resources in determining body size distributions. In mid-winter in India there are more large…

Clinal variation in body and cell size in a widely distributed vertebrate ectotherm

This study suggests that neither Bergmann’s rule nor cell size variation sufficiently explain the body size cline observed in the spotted turtle, and hypothesizes that patterns in body size are related to variation in female size at maturity and reproductive cycles.

Factors controlling the migration phenology of Siberian Phylloscopus species

It is found that spring migration phenology was best explained by moult strategy and the preferred prey size, while autumn migration Phenology was linked to the southernmost wintering latitude of the species.

Is earlier spring migration of Tatarstan warblers expected under climate warming?

There was no evidence over the whole period that the warblers returned to their breeding sites significantly earlier, mainly because local temperatures for April and May, months when the majority of birds arrived from their wintering grounds, did not increase significantly.

Latitudinal clines in food distribution correlate with differential migration in the Western Sandpiper.

It is reported that a latitudinal cline in intertidal food distribution is associated with the nonbreeding distribution of the Western Sandpiper (Calidris mauri), and the greatest relative abundance of surface prey occurred at northern nonbreeding sites and declined with decreasing latitude.

Biometry and phenology of two sibling Phylloscopus warblers on their circum-Mediterranean migrations

The study showed that populations that breed in southwestern Europe migrate through Gibraltar and winter in West Africa are able to accomplish migration in comparatively good body condition, in contrast to those that winter in East Africa, migrate through Israel and have to endure the combined challenge of crossing the Sahel, Sahara and Sinai deserts before reaching their breeding grounds across southeast Europe and southwest Asia.

Effects of body size on sex‐related migration vary between two closely related gull species with similar size dimorphism

It is concluded that the effect of body size on sex-related migratory strategies may vary between closely related, sympatric species despite similar size dimorphism.

Early diversification of sperm size in the evolutionary history of the old world leaf warblers (Phylloscopidae)

It is found that sperm length differs markedly across species, spanning about 40% of the range observed across a larger selection of passerine birds, implying that the majority of divergence in sperm length has occurred early in the evolutionary history of this clade with subsequent evolutionary stasis.

Latitudinal differences in life-history traits and parental care in northern and southern temperate zone House Wrens

South temperate songbirds differ from north temperate species in life-history traits, having greater adult survival, smaller clutch size, longer developmental periods and extended parental care, but there are no significant differences in adult survival probability between populations; however, the data did not support the hypothesis that smaller clutches are the consequence of greater food limitation in the south.

Population Regulation and Character Displacement in a Seasonal Environment

This work uses a quantitative genetic model to study the effects of differential reproductive output in the summer or breeding season on character displacement in the winter or nonbreeding season of Old World leaf warblers, and shows how population regulation in the two seasons becomes linked.

Wintering of Leaf Warblers (Phylloscopus Boie, 1826) in Gangajalghati: First Photographic Evidence of Four Species from Northern Bankura, West Bengal, India

The work documented the visit of dusky and greenish warblers to Bankura for the first time in the past 40 years and recorded the wintering of common chiffchaff and Hume's leaf warblers as the first evidence from the district.

The breeding season distribution of species among habitats may be partly a result of inherent differences in foraging abilities, but that other factors, probably including current competition, must contribute to limiting distributions.

EVOLUTION OF BREEDING DISTRIBUTIONS IN THE OLD WORLD LEAF WARBLERS (GENUS PHYLLOSCOPUS)

Among Palearctic warblers of the genus Phylloscopus those species that breed farther north occupy larger geographical ranges than those which breed farther south (Rapoport's rule), and the midpoint of breeding range in a north‐south direction has been an exceptionally labile trait through evolutionary time.

Latitudinal gradients in butterfly body sizes: is there a general pattern?

It is concluded that general ecological explanations for geographical trends in butterfly body sizes are inappropriate, and gradients largely reflect historical patterns of speciation within and between taxa in each biogeographical realm.

Geographic Size Variation in Birds and Its Relationship to Climate

The hypothesis that increased evaporation at high altitudes and in arid areas accentuates the depression of a wet- bulb thermometer may partially account for several cases of size variation in birds cited by others as disturbing exceptions to Bergmann's ecogeographic rule.

Evolution of ecological differences in the Old World leaf warblers

A phylogeny is used for eight sympatric species of warbler in the genusPhylloscopus, based on their mitochondrial DNA sequences, to remove the effects of historical legacy, and finds strong support for adaptive interpretations of among-species variation in habitat selection, prey-size choice and feeding method.

Most hypotheses proposed to account for a latitudinal species-diversity gradient in a particular taxon (e.g., the "time" hypothesis and the "predation" hypothesis, after Pianka 1966) can operate…

Correlates of wing morphology with foraging behaviour and migration distance in the genus Phylloscopus

Both foraging behaviour and migration distance have affected wing size and shape evolution in the genus Phylloscopus, and species with longer wings migrate further and hover less than species with shorter wings.

Size Distributions of Butterfly Species and the Effect of Latitude on Species Sizes

For butterfly species (Papilionoidea) of the Australian and Afrotropical regions, average wingspan decreases with increasing latitude, and possible reasons are discussed for the effect of latitude on butterfly species sizes, and for skewed species number/size distributions.

Notes on Environmental Determinants of Tropical Versus Temperate Insect Size Patterns

Two features of the habitat, the variation of moisture patterns in space and the fluctuation of resources in time, appear to be correlated with most of the differences in the means and standard deviations of these distributions.
