Spring Phenology and Trophic Ecology of Trees, Caterpillars, and Migrating Neotropical -Nearctic Songbirds
… (Parulidae) and vireos (Vireonidae) during spring migration in 2001--2003 at Trelease Woods, a deciduous forest fragment near Urbana, Illinois, USA (40°09'N, 88°10'W). I hypothesized that (1) the photoperiod-driven pattern of migration of wood warblers and vireos through the stopover …

Birth order as a source of diversification in spring phenology and its potential effects on performance in greater duckweed, Spirodela polyrhiza
The timing of both winter freeze-up and spring thaws are unpredictable and under these variable environments, clonal populations of Spirodela polyrhiza (greater duckweed) provide an excellent case study of phenotypic diversification as a risk aversion strategy. Previous research on this species has …

The Role of Climate Variability in Duck Population Ecology
… forest, 1982-2013. I found limited evidence that spring phenology, growing season length or productivity influenced annual population growth rates, and effects were not always in the direction predicted based on species-specific timing of breeding. Second, I evaluated impacts and potential …

Local impacts of global change: shifting range limits, advancing phenology, and communicating research
… and second, species are advancing their spring phenology. Climate change is having these effects because climate controls both where species exist and when species reproduce. However, a significant gap in our knowledge are the causes and consequences of species-to-species variability in …

Drivers of Productivity of Montane and Boreal Breeding Ducks
… by climatic and biotic factors, and offspring production and recruitment are key components of population growth in many duck species. For lesser scaup (Aythya affinis; scaup), a species of conservation concern, productivity can be particularly influential to population growth, although …

Quantifying population- and individual-level processes in Greenland white-fronted geese (Anser albifrons flavirostris) for holistic conservation planning
… areas, including cold temperatures during late spring and precipitation during brood-rearing. I also found that earlier spring phenology on staging areas negatively affected reproductive rates of geese staging in southern Iceland and increased snow on breeding areas negatively affected …

MOVING THE GOALPOSTS: MIGRATORY BIRDS IN A CHANGING WORLD
… songbirds adjust the rate and timing of spring migration based on the vegetation phenology they encounter within North America which may allow them to keep pace with advancing spring phenology under climate change. In the spring, migrating birds must quickly reach their breeding grounds …
