MacArthur's Warblers - Stanford University
WEBFor his doctoral dissertation, the late Robert MacArthur, who became one of the nation's leading ecologists, set out to determine whether the five species of warblers actually did occupy the same niche.
Re-assessing niche partitioning in MacArthur’s Warblers: foraging ...
WEBAug 29, 2022 · Here, we reassess MacArthur’s conclusions across an expanded set of syntopic warbler species in a forest in northern New York. We combine morphometrics, quantitative foraging data, and fecal metabarcoding—a direct measure of warbler diet—to study competition and niche partitioning in an evolutionary framework.
Extensions and limitations of MacArthur (1958): A review of ecological …
WEBMar 15, 2022 · We focus on New World wood warblers (Parulidae), beginning with Robert MacArthur’s iconic 1958 paper in which he shows how subtle foraging behaviors, purportedly linked to dietary differences, within spruce trees contribute to the coexistence of 5 spruce-woods warbler species.
Revisiting MacArthur’s Classic Study of Niche Partitioning of
WEBIn 1956 and 1957, Robert H. MacArthur studied the ecology of five species of the genus Setophaga (wood warbler), resulting in contributions to the theory of niche partitioning. MacArthur asserted that the five Setophaga are sympatric species that evolved to occupy separate behavioral niches.
Behavioral niche partitioning reexamined: Do behavioral …
WEBApr 18, 2020 · We combined data on foraging behavior, available prey, and observed diets of five coexisting species of New World wood warblers (Parulidae), a system that has been foundational to our understanding of behavioral niche partitioning.
Density-dependent diversification in North American wood warblers
WEBOct 10, 2008 · Here we develop a new conceptual framework that distinguishes density dependence from alternative processes that also produce temporally declining diversification, and we demonstrate this approach using a new phylogeny of North American Dendroica wood warblers.
Re-assessing niche partitioning in MacArthur's Warblers: foraging ...
WEBAug 29, 2022 · We combine morphometrics, quantitative foraging data, and fecal metabarcoding--a direct measure of warbler diet--to study competition and niche partitioning in an evolutionary framework.
Knowing Your Warblers: Thoughts on the 50th Anniversary of …
WEBOct 1, 2008 · Once a student knows she can walk into an Oklahoma wood lot and see 20 species of birds, 15 of grasshoppers, and 20 or so of ants, the next question, often unprodded, is “what do they all do?” Second, the warbler …
WEBmethodological contribution to the general field of ecological niche modeling (ENM) by integrating climatic and palynological data to empirically estimate both abiotically and biotically suitable areas which that has only been done theoretically so far.
How do so many wood warbler species coexist?
WEBMar 24, 2022 · Our recent review paper employs several new approaches and information, especially dietary data, to address warbler competition and coexistence, which we examine from both ecological and evolutionary perspectives.
