Natal dispersal and first-year survival in a neotropical migratory songbird
… survival, I determined the distribution of natal dispersal distances in Prothonotary Warblers (Protonotaria citrea) breeding within a nest box study system covering a large area. Surveys outside the nest box study system (up to 30 km in all directions) supported the legitimacy of the dispersal …

Modeling the Dispersion of Eastern Oyster Larvae (<i>Crassostrea virginica</i>) and its Effects on the Movement of Disease Resistant Genes in the Delaware Bay Estuary
… settlement size (330 µm). The simulated dispersal patterns showed that oyster larvae tend to drift down-estuary during the spawning season. The net result is that mixing of oyster larvae throughout Delaware Bay is extensive. Larval success is strongly affected by variability of …

The sedimentology, geochemistry and diagenesis of West Rand Group sediments in the Heidelberg area, Transvaal
… units of the West Rand Group, the current dispersal pattern and the probable, equivalent modern day depositional environment. The extent of diagenesis and metamorphism was investigated by using two white mica techniques. The chemistry of the shales was related to its mineralogy and a …

Social interaction and dispersal patterns of golden snub-nosed monkeys (Rhinopithecus roxellana) living in multi-level societies
… presence and complexity of kinship networks and dispersal patterns in R. roxellana based on genetic data, and 4) the behavioral mechanisms regulating social interactions within multi-level social networks, and whether these are most consistent with kin selection theory, reciprocity theories, or …

Population structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori)
… mortality. Population structure and dispersal rates were assessed using 281 samples collected from individual Hector’s dolphins of ten population groups representing the known geographic range of this species. Variation among mitochondrial DNA sequences (ΦST = 0.545) and …
