Book Synopsis Clark's Nutcrackers and Whitebark Pine by : Taza D. Schaming
Download or read book Clark's Nutcrackers and Whitebark Pine written by Taza D. Schaming and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the face of widespread environmental change, understanding and promoting resilience and stability of plant-animal seed disperser mutualisms is key to effective conservation strategies. My two primary objectives were to (1) investigate the response of the keystone mutualism between whitebark pine (Pinus albicaulis) and Clark's nutcrackers (Nucifraga columbiana) to declining habitat in the Greater Yellowstone Ecosystem, and (2) suggest management strategies to help ensure persistence of Clark?s nutcrackers, and their important seed dispersal function. Between 2009 and 2016, I studied Clark?s nutcracker demography and behavioral plasticity by evaluating breeding ecology, space use, seasonal habitat selection and use, foraging ecology, and emigration, as a function of habitat quality and abundance. I carried out occupancy surveys, tracked individuals via radio and satellite, conducted behavioral observations, and monitored nests. Clark?s nutcracker demography and behavior was intimately associated with whitebark pine habitat. Population-wide failure to breed followed low whitebark pine cone crops, and in breeding years, fledging success increased with whitebark pine abundance, but decreased in higher mortality stands. Clark?s nutcracker occurrence was associated with both presence of cone-bearing whitebark pines, and landscape-scale abundance of the pines, suggesting conservation strategies should focus efforts at the landscape scale. The birds selected disproportionately high amounts of Douglas-fir (Pseudotsuga menziesii) habitat for their home range, and foraged heavily on Douglas-fir cones, suggesting that whitebark pine should be managed within a habitat mosaic with Douglas-fir. The Clark?s nutcracker-whitebark pine mutualism appears functional in the region because birds were available to disperse seeds. However, it is unclear whether the mutualism is stable. Clark?s nutcrackers are highly mobile facultative migrants, and the majority of radio- and satellite-tagged birds disappeared during both the 2012 high and 2015 moderate whitebark pine cone crops. Managing Clark?s nutcrackers presents a complex conservation challenge, but I suggest promoting stability of Clark?s nutcracker populations, and focusing on the metapopulation in particular, is necessary for effective whitebark pine conservation. In this dissertation, I conclude by outlining recommended management strategies and key research questions that still need to be answered, finishing with important considerations that should be taken into account when designing a conservation plan for plant-animal seed disperser mutualisms.

Download or read book Made for Each Other written by Ronald M. Lanner and published by Oxford University Press, USA. This book was released on 1996 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Made for Each Other: A Symbiosis of Birds and Pines, Ronald M. Lanner details for the first time this fascinating relationship between wingless-seeded pine trees and seed-dispersing Corvids (nutcrackers and jays), showing how mutualism can drive not only each others' evolution, but affect the ecology of many other members of the surrounding ecosystem as well. In a complex process of mutual dependency, myriad species of both plants and animals - from Engelmann spruce, elk, and moose to red squirrels, bear, and fungi - advance the overall life cycle by taking advantage of the ecological terrain that precedes them. Focusing on the Rocky Mountains and the American Southwest, and ranging as far afield as the Alps, Finland, Siberia, and China, this beautifully illustrated and gracefully written work illuminates the phenomenon of co-evolution.

Book Synopsis The Biology of Mutualism by : Douglas H. Boucher
Download or read book The Biology of Mutualism written by Douglas H. Boucher and published by New York : Oxford University Press. This book was released on 1985 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The view of nature as `red in tooth and claw', as a jungle in which competition and predation are the predominant themes, has long been important in both the scientific and popular literature. However, in the past decade another view has become widespread among ecologists: the idea that mutualisms--mutually beneficial interactions between species--are just as important as competition and predation. This book is one of the first to explore this theme. Ideas and theories applicable to all sorts of mutualisms are presented and, where appropriate, examined in the light of concrete data. Themes explored include: the organisms involved, both animal and plant; how specializations evolved once mutualisms formed; how mutualisms affect population dynamics and community structure; and the role of mutualisms in different environments. The book will be of special interest to ecologists and a wide range of biologists.
