Hall and published by Geological Society of America. This book was released on 2002 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3000 middle and late Cenozoic nearshore marine molluscan taxa from western California are assigned to six time periods, spanning ~25 m.y. In this interdisciplinary study, western California is palinspastically restored for each of the time periods by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. In addition, this volume reveals positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; defines "equable" based effective temperatures; and analyzes extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline.

Available in PDF, EPUB and Kindle. Book excerpt: In a three part study, we analyzed: (1) population-level response of the coachwhip snake, (Masticophis flagellum) and striped racer (M. lateralis) to fragmentation of scrub habitats in coastal southern California using site occupancy models and presence/apparent absence data; (2) space-use behavior of coachwhip snakes and racers in fragmented and continuous habitats of coastal southern California using data from radio-telemetry; and (3) phylogeography and population genetic variation throughout the range of both species with emphasis on coachwhip populations in southern California using mitochondrial DNA sequence and RFLP data. Part 1 revealed disproportionate loss of coachwhip populations from fragmented areas. Unlike the racer, the coachwhip tended to be absent from sites embedded in isolated landscapes, even at large spatial scales. The two species showed large differences in rates of local extinction and probability of detection, with coachwhip populations exhibiting variable rates of detection and greater likelihood of local extinction. Habitat composition influenced site occupancy. Coachwhip snakes preferred sites with open sage scrub and grassland. Racers preferred scrub dominated sites. In Part 2 coachwhip snakes exhibited great plasticity in spacing and movement patterns between sites, showing large differences in movement response to changes in local conditions and amount of available space. In sympatry, coachwhip snakes and racers showed large differences in home range size, rate of travel, and movement distance, with coachwhip snakes ranging more widely than racers. Differences in habitat use fit well with occupancy patterns. Coachwhip snakes utilized both scrub and grassland, and racers utilized largely only scrub. In Part 3 phylogenetic analyses recovered significant structure in both species, with seven well-supported and geographically coherent clades recovered from coachwhip populations sampled throughout the range of the species. High density sampling within southern California recovered four cryptic coachwhip lineages in contact and organized geographically by bioregion. Collectively, results suggest the greater vulnerability of the coachwhip to land-use change is related to differences in habitat use, movement, and rates of population turnover. Unless the few remaining large, contiguous landscapes of grassland and open scrubland are incorporated into regional conservation planning, long-term persistence of coachwhip lineages is unlikely in the future landscape of California.

Available in PDF, EPUB and Kindle. Book excerpt: With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development.
