EMP protocols for rodents and lizards performed well, but some recalibration is needed. Populations declined to observed minima during a 1989-1990 drought, and increased with strong rains during 1990-1995. Small rodents (pocket mice) increased fastest, but declined first, after 1992.

Sequence heterochronies are evolutionary changes between ancestor and descendent in the relative order of events in development. Developmental sequences have been proposed as potential sources of phylogenetic information and sequence heterochronies as potentially important in evolutionary change. However, existing methodology for the analysis of developmental sequences suffers from serious problems. This thesis presents a new method, PGi (Parsimov-based Genetic Inference), which overcomes these problems; PGi is more accurate and more efficient than existing methods. Using PGi with a comparativ

Vertebrate genomes exhibit global methylation of cytosine residues where they occur in a cytosine-guanine dinucleotide (CpG) context and this epigenetic mark is generally thought to be repressive to transcription.

These non-methylated regions exhibit CpG content close to expected levels as they escape the depletion of CpGs observed across the methylated fraction of the genome.

Abstract:
‘Eco-evolutionary feedbacks’ occur when evolution of organismal traits causes environmental change that drives further evolution. Predator and prey interactions provide good examples of eco-evolutionary feedbacks. Here I examine the potential for eco-evolutionary feedbacks between three-spined sticklebacks (Gasterosteus aculeatus, hereafter ‘stickleback’) and their zooplankton prey in lochs (lakes) on the Scottish island of North Uist. Many lochs on the island were colonised by sticklebacks after the last glaciation, approximately 10,000-15,000 years ago. Previous work has shown that stickleba

Distinguishing marine and freshwater animals in the fossil record is a long-standing problem in paleontology. The physiological tolerances of extinct animals usually are inferred from environmental indicators and/or on the physiology of nearest living relatives. These types of evidence are often ambiguous and may be confounded by factors such as post-mortem transport and polymorphism in the living relatives. A solution to this problem is to combine these types of data with analyses of the oxygen isotope compositions of the phosphate (δ¹⁸O(p)) and the carbon isotope compositions of the carbonat

All multicellular organisms originate from a small set of totipotent embryonic stem cells that differentiate into a structured body plan during embryogenesis. These cells share the common morphology of undifferentiated cells with a high nucleus/cytoplasm ratio, few cytoplasmic organelles and absence of specific functions, and reach their full functionality through various steps in which they progress towards their specificity. Stem cells with different plasticity persist in tissues during the whole life of the organism and they can be useful in replacing adult cells after their damage or death
