CHAPTER 8 – Fish Biogeography and Molecular Clocks: Perspectives from the Panamanian Isthmus
This chapter highlights the biogeography of fishes with perspectives from the Panamanian isthmus as it provides a rich landscape to study the evolution of fish and molecules. It focuses on fish… Expand
Body size, metabolic rate, generation time, and the molecular clock.
There is increasing evidence for variation in rates of nucleotide substitution among divergent taxonomic groups. Here, we summarize published rate data and show a strong relationship between… Expand
Rates of mitochondrial DNA evolution in sharks are slow compared with mammals
THE rate of mitochondrial DNA (mtDNA) evolution has been carefully calibrated only in primates1. Similarity between the primate calibration and rates estimated for other vertebrates2–4 has led to… Expand
Seasonal Dynamics of Previously Unknown Fungal Lineages in Tundra Soils
The finding that microbial communities are active under snow has changed the estimated global rates of biogeochemical processes beneath seasonal snow packs. We used microbiological and molecular… Expand

1. Foraging range is a key aspect of the ecology of 'central place foragers'. Estimating how far bees fly under different circumstances is essential for predicting colony success, and for estimating… Expand
Sex-biased dispersal of great white sharks
In some respects, these sharks behave more like whales and dolphins than other fish.
Marine incursion into South America
The Amazon basin harbours the most diverse assemblage of freshwater fishes in the world, including a disproportionately large number of marine-derived groups, such as stingrays, flatfishes,… Expand
Historical Biogeography of Two Alpine Butterflies in the Rocky Mountains: Broad-scale Concordance and Local-scale Discordance
Aim We inferred the phylogeography of the alpine butterfly Colias meadii Edwards (Pieridae) and compared its genetic structure with that of another high elevation, co-distributed butterfly,… Expand
Protein evolution in different cellular environments: cytochrome b in sharks and mammals.
DNA sequences for the mitochondrial cytochrome b gene were determined for 13 species of sharks. Rates and patterns of amino acid replacement are compared for sharks and mammals. Absolute rates of… Expand
Tracking butterfly movements with harmonic radar reveals an effect of population age on movement distance

We used harmonic radar to track freely flying Glanville fritillary butterfly (Melitaea cinxia) females within an area of 30 ha. Butterflies originated from large and continuous populations in China… Expand
