Washington State University, United States -- Washington. Articles. Differences in the breeding biology of Richard’s Pipit, compared with the alpine-breeding American Pipit (Anthus rubescens), include smaller clutch size, smaller clutch mass as a percentage of female mass, and high frequency of double-brooding.

These differences may be due to the shorter duration of snowcover and the longer growing season in the alpine zone of the Snowy Mountains compared with the North American alpine Cited by: - Ph.D. Zoology, Washington State University (dissertation: "Clutch- and egg-size variation of American Pipits in alpine environments") - M.A.

Variation in size and shape of American Pipit (Anthus rubescens) eggs was studied from to at two sites in the Beartooth Mountains, Park County, Wyoming. Differences in four egg traits. Date of clutch initiation and mean clutch size for an alpine population of American Pipits (Anthus rubescens) in northern Wyoming varied significantly among.

To examine sources of environmental variation in egg size while controlling for yearly and individual variation I used restricted maximum likelihood, linear mixed models (GLIMs) as implemented in SAS (SAS Institute Inc., ).Including female identity as a random factor in the models allows for the presumably operating long-term effects of environmental, genetic Cited by:   We examined timing of breeding, nest site selection and nest survival of Horned Larks (Eremophila alpestris), Savannah Sparrows (Passerculus sandwichensis) and American Pipits (Anthus rubescens) in an alpine habitat on Hudson Bay Mountain, BC, Canada in – These species partitioned their nesting niches temporally and spatially.

We Cited by: Abstract.— Incubation behavior is one component of reproductive effort and thus influences the evolution of life‐history strategies. We examined the relative importance of body mass, frequency of mate feeding, food, nest predation, and ambient temperature to explain interspecific variation in incubation behavior (nest attentiveness, on‐ and off‐bout durations, and nest trips per hour Cited by: The Significance of Clutch‐size.

Life-history variation among mountain populations can be explained by both phenotypic plasticity and local adaptation.

The former, by means of which organisms with the same genetic constitution adjust their development to the current conditions, is generally considered poorly efficient for coping with extreme environments (Grime ; Cited by:   Egg size in many birds may not vary if there is a threshold egg size for viability (Wiebe and Bortolotti, ), or if egg size has high heritability (Cooke et al., ).

Reproductive success may be lower in harsh years because of smaller clutches or poorer egg or offspring survival, and often nest depredation is higher (Ganter and Boyd, ).Cited by:   Understanding how environmental factors affect ecological parameters is important to understanding and predicting impacts of environmental change.

Given evidence and anticipated impacts of climate variability, this is especially true with respect to sea ice and its role in animal life history in northern regions.

Pérez. At present we are unaware of a study exploring multiple factors including environmental variation and clutch timing simultaneously in multiple species.

Finally, we compare our results with other species nesting in tundra environments and discuss common patterns. The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal.

Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero". We investigated patterns and causes of variation in clutch sizes in a guild of five species of temperate-nesting dabbling ducks (Mallard [Anas platyrhynchos], Northern Pintail [“pintail,” A.

Timing of breeding activities and the influence of weather.

Over the past century, the interior West, which includes the lion?s share of the country's high-mountain habitats, has warmed about 1 degree F.

Computer models show the region heating up an. The clutch size of most African and Asian bulbuls is usually eggs, but some species also lay eggs (Kitowski, ).

The clutch size of P. jocosus in Xishuangbanna was similar, but the mean clutch size was smaller than P. Cited by: 3. Elevational gradients create environmental variation that is hypothesized to promote variation in life‐history strategies.
