The influence of a competitor on the geographic mosaic of coevolution between crossbills and lodgepole pineC W Benkman
Department of Biology, New Mexico State University, Las Cruces, 88003 8001, USA
Evolution 55:282-94. 2001..e., coevolutionary hotspots) but not where red squirrels are present (i.e., coevolutionary cold-spots)...
Divergent selection drives the adaptive radiation of crossbillsCraig W Benkman
Department of Biology, MSC 3AF, New Mexico State University, Las Cruces, New Mexico 88003 8001, USA
Evolution 57:1176-81. 2003..This work strongly supports a key tenet of the ecological theory of adaptive radiations; namely, divergent selection for utilizing alternative resources is the ultimate cause of adaptive radiations...
Reciprocal selection causes a coevolutionary arms race between crossbills and lodgepole pineCraig W Benkman
Department of Biology, New Mexico State University, Las Cruces, New Mexico, 88003, USA
Am Nat 162:182-94. 2003..These results show that crossbills and lodgepole pine exhibit reciprocal adaptations in response to reciprocal selection, and they provide insight into the traits mediating and responding to selection in a coevolutionary arms race...
Coevolution between Hispaniolan crossbills and pine: does more time allow for greater phenotypic escalation at lower latitude?Thomas L Parchman
Department of Biology, MSC 3AF, New Mexico State University, Las Cruces, New Mexico 88003 8001, USA
Evolution 61:2142-53. 2007....
Interactions among moths, crossbills, squirrels, and lodgepole pine in a geographic selection mosaicAdam M Siepielski
Department of Biology, MSC 3AF, New Mexico State University, Las Cruces, New Mexico 88003-8001, USA
Evolution Int J Org Evolution 58:95-101. 2004..These results demonstrate the importance of considering the evolutionary consequences of community context in locally evolved (coevolved) traits and interactions...
A coevolutionary arms race causes ecological speciation in crossbillsJulie W Smith
Department of Biology, New Mexico State University, Las Cruces, New Mexico 88003, USA
Am Nat 169:455-65. 2007..These extremely high levels of reproductive isolation indicate that the divergent selection resulting from the coevolutionary arms race between crossbills and lodgepole pine is causing the South Hills crossbill to speciate...
Survival and population size of a resident bird species are declining as temperature increasesLeonard Santisteban
Department of Biology, New Mexico State University, Las Cruces, NM 88003, USA
J Anim Ecol 81:352-63. 2012....

Mol Ecol 15:1873-87. 2006....
Can selection by an ectoparasite drive a population of red crossbills from its adaptive peak?Craig W Benkman
Department of Biology, MSC 3AF, New Mexico State University, Las Cruces, New Mexico 88003, USA
Evolution 59:2025-32. 2005..This selection may also explain why the degree of sexual size dimorphism has decreased by nearly 50% since 1998...
Diversifying coevolution between crossbills and black spruce on NewfoundlandThomas L Parchman
Department of Biology, New Mexico State University, Las Cruces 88003-8001, USA
Evolution Int J Org Evolution 56:1663-72. 2002....

Department of Biology, Pacific Lutheran University, Tacoma, WA 98447, USA
Proc Biol Sci 279:4223-9. 2012..These patterns of association therefore provide a mechanism by which increasing divergent selection can lead to increasing reproductive isolation...
Extreme environmental variation sharpens selection that drives the evolution of a mutualismAdam M Siepielski
Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA
Proc Biol Sci 274:1799-805. 2007..Infrequent events can thus be essential to both adaptive evolution and the evolutionary dynamics of species interactions...
The local introduction of strongly interacting species and the loss of geographic variation in species and species interactionsCraig W Benkman
Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA
Mol Ecol 17:395-404. 2008..Such introductions have eliminated incipient species of crossbills (Loxia spp.) co-evolving in arms races with conifers and will likely have considerable impacts on community structure and ecosystem processes...
A seed predator drives the evolution of a seed dispersal mutualismAdam M Siepielski
Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA
Proc Biol Sci 275:1917-25. 2008..Given that adaptive evolution in response to antagonists frequently impedes one kind of mutualistic interaction, the evolution of alternative mutualistic interactions may be a common by-product...
