Niche conservatism as an emerging principle in ecology and conservation biology

JJ Wiens, DD Ackerly, AP Allen, BL Anacker… - Ecology …, 2010 - Wiley Online Library
The diversity of life is ultimately generated by evolution, and much attention has focused on
the rapid evolution of ecological traits. Yet, the tendency for many ecological traits to instead …

Why do we still use stepwise modelling in ecology and behaviour?

MJ Whittingham, PA Stephens… - Journal of animal …, 2006 - Wiley Online Library
Summary 1 The biases and shortcomings of stepwise multiple regression are well
established within the statistical literature. However, an examination of papers published in …

Consequences of the Allee effect for behaviour, ecology and conservation

PA Stephens, WJ Sutherland - Trends in ecology & evolution, 1999 - cell.com
Warder C. Allee brought attention to the possibility of a positive relationship between
aspects of fitness and population size 50 years ago. Until recently, however, this concept …

Mutations of the BRAF gene in human cancer

H Davies, GR Bignell, C Cox, P Stephens, S Edkins… - Nature, 2002 - nature.com
Cancers arise owing to the accumulation of mutations in critical genes that alter normal
programmes of cell proliferation, differentiation and death. As the first stage of a systematic …

Patterns of somatic mutation in human cancer genomes

C Greenman, P Stephens, R Smith, GL Dalgliesh… - Nature, 2007 - nature.com
Cancers arise owing to mutations in a subset of genes that confer growth advantage. The
availability of the human genome sequence led us to propose that systematic resequencing …

[HTML][HTML] Massive genomic rearrangement acquired in a single catastrophic event during cancer development

PJ Stephens, CD Greenman, B Fu, F Yang, GR Bignell… - cell, 2011 - cell.com
Cancer is driven by somatically acquired point mutations and chromosomal rearrangements,
conventionally thought to accumulate gradually over time. Using next-generation …

Ab initio calculation of vibrational absorption and circular dichroism spectra using density functional force fields

PJ Stephens, FJ Devlin, CF Chabalowski… - The Journal of …, 1994 - ACS Publications
The unpolarized absorption and circular dichroism spectra of the fundamental vibrational
transitions of the chiral molecule 4-methyl-2-oxetanone are calculated ab initio. Harmonic …

[HTML][HTML] Mutational processes molding the genomes of 21 breast cancers

S Nik-Zainal, LB Alexandrov, DC Wedge, P Van Loo… - Cell, 2012 - cell.com
All cancers carry somatic mutations. The patterns of mutation in cancer genomes reflect the
DNA damage and repair processes to which cancer cells and their precursors have been …

The landscape of cancer genes and mutational processes in breast cancer

PJ Stephens, PS Tarpey, H Davies, P Van Loo… - Nature, 2012 - nature.com
All cancers carry somatic mutations in their genomes. A subset, known as driver mutations,
confer clonal selective advantage on cancer cells and are causally implicated in …

[HTML][HTML] A comprehensive catalogue of somatic mutations from a human cancer genome

ED Pleasance, RK Cheetham, PJ Stephens… - Nature, 2010 - nature.com
