Community Diversity: Relative Roles of Local and Regional Processes
TLDR
Observations suggest that regional and historical processes, as well as unique events and circumstances, profoundly influence local community structure and ecologists must broaden their concepts of community processes and incorporate data from systematics, biogeography, and paleontology into analyses of ecological patterns and tests of community theory.
A comprehensive framework for global patterns in biodiversity
TLDR
The present study proposes to reconcile the different spatial and temporal scales of regional species production and local constraint on species richness, bringing speciesProduction and extinction onto the same scale and establishing a link between local and regional processes.
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
TLDR
Two major hypotheses for the origin of the latitudinal diversity gradient are reviewed, including the time and area hypothesis and the diversification rate hypothesis, which hold that tropical regions diversify faster due to higher rates of speciation, or due to lower extinction rates.
EARLY BURSTS OF BODY SIZE AND SHAPE EVOLUTION ARE RARE IN COMPARATIVE DATA
TLDR
It is suggested that the classical model of adaptive radiation, where morphological evolution is initially rapid and slows through time, may be rare in comparative data.
Dioecy and its correlates in the flowering plants
TLDR
Dioecy appears to have evolved most frequently via monoecy, perhaps through divergent adjustments of floral sex ratios between individual plants, as revealed by multivariate analysis.
Large-scale processes and the Asian bias in species diversity of temperate plants
TLDR
The most probable cause of the EAS-ENA anomaly in diversity is the extreme physiographical heterogeneity of temperate eastern Asia, especially compared with eastern North America, which in conjunction with climate and sea-level change has provided abundant opportunities for evolutionary radiation through allopatric speciation.
An analysis of nesting mortality in birds
TLDR
It is postulated that interspecific differences in mortality rates are determined by evolutionarily acceptable levels of adult risk to lower mortality rates of offspring through parental care, adult adaptations of morphology and behavior for foraging, and—most import—the diversity of predators to which a species must adapt.
Avian growth and development : evolution within the altricial-precocial spectrum
TLDR
The data set of Avian Growth Parameters Summary, Conclusions, and Research Agenda shows that the evolution of Developmental Mode in Birds is driven by a combination of Variation, Constraint, and Phylogeny.
