Patterns and processes in reef fish diversity.

Abstract: A central aim of ecology is to explain the heterogeneous distribution of biodiversity on earth. As expectations of diversity loss grow1,2,3,4,5, this understanding is also critical for effective management and conservation. Although explanations for biodiversity patterns are still a matter for intense debate5, they have often been considered to be scale-dependent6,7. At large geographical scales, biogeographers have suggested that variation in species richness results from factors such as area, temperature, environmental stability, and geological processes, among many others5,7,8,9,10,11,12,13,14. From the species pools generated by these large-scale processes, community ecologists have suggested that local-scale assembly of communities is achieved through processes such as competition, predation, recruitment, disturbances and immigration5,6,7,8,15,16. Here we analyse hypotheses on speciation and dispersal for reef fish from the Indian and Pacific oceans and show how dispersal from a major centre of origination can simultaneously account for both large-scale gradients in species richness and the structure of local communities.

Neuropsychological significance of variations in patterns of academic performance: verbal and visual-spatial abilities.

Abstract: Forty-five 9- to 14-year-old children with learning disabilities whose WISC Full Scale IQs fell within the range of 86–114 were divided into three groups on the basis of their patterns of reading, spelling, and arithmetic achievement. Group 1 was composed of children who were uniformly deficient in reading, spelling, and arithmetic; children in Group 2 were relatively adept at arithmetic as compared to their performance in reading and spelling; Group 3 was composed of children whose reading and spelling performances were average or above, but whose arithmetic performance was relatively deficient. The performances of these children on 16 dependent measures were compared. The performances of Groups 1 and 2 were superior to that of Group 3 on measures of visual-perceptual and visual-spatial abilities; Group 3 performed at a superior level to that of Groups 1 and 2 on measures of verbal and auditory-perceptual abilities. The results are discussed in terms of the relationships between varying patterns of academic abilities and patterns of brain-related behaviors, and the nature of the neuropsychological abilities that may limit performance on arithmetic calculation tasks.

Rapid Evolution of Egg Size in Captive Salmon

Abstract: Captive breeding and release programs, widely used to supplement populations of declining species, minimize juvenile mortality to achieve rapid population growth However, raising animals in benign environments may promote traits that are adaptive in captivity but maladaptive in nature In chinook salmon, hatchery rearing relaxes natural selection favoring large eggs, allowing fecundity selection to drive exceptionally rapid evolution of small eggs Trends toward small eggs are also evident in natural populations heavily supplemented by hatcheries, but not in minimally supplemented populations Unintentional selection in captivity can lead to rapid changes in critical life-history traits that may reduce the success of supplementation or reintroduction programs
