Major Themes and Unsolved Problems --References --IndexEvolutionary biology has long sought to explain how new traits and new species arise. Darwin maintained that competition is key to understanding this biodiversity and held that selection acting to minimize competition causes competitors to become increasingly different, thereby promoting new traits and new species. Despite Darwin's emphasis, competition's role in diversification remains controversial and largely underappreciated. In their synthetic and provocative book, evolutionary ecologists David and Karin Pfennig explore competition's role in generating and maintaining biodiversity. The authors discuss how selection can lessen resource competition or costly reproductive interactions by promoting trait evolution through a process known as character displacement. They further describe character displacement's underlying genetic and developmental mechanisms. The authors then consider character displacement's myriad downstream effects, ranging from shaping ecological communities to promoting new traits and new species and even fueling large-scale evolutionary trends. Drawing on numerous studies from natural populations, and written for a broad audience, Evolution's Wedge seeks to inspire future research into character displacement's many implications for ecology and evolution.Organisms and EnvironmentsDivergence (Biology)Competition (Biology)Animal diversityElectronic books.Divergence (Biology)Competition (Biology)Animal diversity.577.8/3Pfennig David W(David William),1955-1040670Pfennig Karin S(Karin Susan),1969-1040671MiAaPQMiAaPQMiAaPQBOOK9910462156503321Evolution's wedge2463723UNINA01964nam0 22003013i 450 VAN0028111920240916022320.151978-88-430-3558-820240916d2008 |0itac50 baitaIT|||| |||||Psicologia dell'invecchiamento e promozione della saluteCaterina Grano, Fabio LucidiRomaCarocci2008171 p.22 cmLa rapida crescita della popolazione anziana rappresenta uno dei fenomeni demografici più marcati cui si è assistito negli ultimi decenni. L'invecchiamento della popolazione enfatizza la necessità di promuovere il benessere fisico, sociale e psicologico lungo il corso della vita e questo cambiamento culturale si riflette nella costruzione di nuovi modelli teorici in ambito gerontologico e nel passaggio da approcci normativi basati sulle modalità ottimali di invecchiamento a modelli che riconoscono e valorizzano qualità e aspetti distintivi della tarda età. Il volume si propone di descrivere le principali teorie psicologico-sociali legate a questo fenomeno.001VAN000160652001 Università210 RomaCarocci684RomaVANL000360GranoCaterinaVANV233875592390LucidiFabioVANV058429472894Carocci <editore>VANV107923650ITSOL20241122RICAhttps://www.carocci.it/prodotto/psicologia-dellinvecchiamento-e-promozione-della-salutehttps://www.carocci.it/prodotto/psicologia-dellinvecchiamento-e-promozione-della-saluteBIBLIOTECA DEL DIPARTIMENTO DI PSICOLOGIAIT-CE0119VAN16VAN00281119BIBLIOTECA DEL DIPARTIMENTO DI PSICOLOGIA16CONS 5004 16OM 848 20240916 BuonoPsicologia dell'invecchiamento e promozione della salute1001687UNICAMPANIA
