Use of energy reserves in fighting hermit crabs
Proceedings of the Royal Society B: Biological Sciences - Tập 271 Số 1537 - Trang 373-379 - 2004

Laetoli footprints reveal bipedal gait biomechanics different from those of modern humans and chimpanzees
Proceedings of the Royal Society B: Biological Sciences - Tập 283 Số 1836 - Trang 20160235 - 2016
Kevin G. Hatala, Brigitte Demes, Brian G. Richmond
Bipedalism is a key adaptation that shaped human evolution, yet the timing and nature of its evolution remain unclear. Here we use new experimentally based approaches to investigate the locomotor mechanics preserved by the famous Pliocene hominin footprints from Laetoli, Tanzania. We conducted footprint formation experiments with habitually barefoot humans and with chimpanzees to quantitat...... hiện toàn bộ
Initial frequency of alleles conferring resistance toBacillus thuringiensispoplar in a field population ofChrysomela tremulae

Persistent organic pollution in a high-Arctic top predator: sex-dependent thresholds in adult survival
Proceedings of the Royal Society B: Biological Sciences - Tập 280 Số 1769 - Trang 20131483 - 2013
Kjell Einar Erikstad, Hanno Sandvik, Tone Kristin Reiertsen, Jan Ove Bustnes, Hallvard Strøm
In long-lived species, any negative effect of pollution on adult survival may pose serious hazards to breeding populations. In this study, we measured concentrations of various organochlorines (OCs) (polychlorinated biphenyl and OC pesticides) in the blood of a large number of adult glaucous gulls ( Larus hyperboreus ) breedin...... hiện toàn bộ
High relatedness selects against hypermutability in bacterial metapopulations
Proceedings of the Royal Society B: Biological Sciences - Tập 274 Số 1615 - Trang 1341-1347 - 2007
Freya Harrison, Angus Buckling
Mutation rate and cooperation have important ecological and evolutionary consequences and, moreover, can affect pathogen virulence. While hypermutability accelerates adaptation to novel environments, hypermutable lineages (‘mutators’) are selected against in well-adapted populations. Using the model organismPseudomonas aeruginosa, we previously demonstrated a fur...... hiện toàn bộ
Monocular focal retinal lesions induce short–term topographic plasticity in adult cat visual cortex
Proceedings of the Royal Society B: Biological Sciences - Tập 266 Số 1418 - Trang 499-507 - 1999

Senescence: why and where selection gradients might not decline with age
Proceedings of the Royal Society B: Biological Sciences - Tập 288 Số 1955 - Trang 20210851 - 2021
Mark Roper, Pol Capdevila, Roberto Salguero‐Gómez
Patterns of ageing across the tree of life are much more diverse than previously thought. Yet, we still do not adequately understand how, why and where across the tree of life a particular pattern of ageing will evolve. An ability to predict ageing patterns requires a firmer understanding of how and why different ecological and evolutionary factors alter the sensitivity of fitness to age-r...... hiện toàn bộ
The influence of cellular physiology on the initiation of mutational pathways inEscherichia colipopulations
Proceedings of the Royal Society B: Biological Sciences - Tập 270 Số 1517 - Trang 843-848 - 2003

Experimental evolution of resistance to an antimicrobial peptide
Proceedings of the Royal Society B: Biological Sciences - Tập 273 Số 1583 - Trang 251-256 - 2006
Gabriel G. Perron, Michael Zasloff, Graham Bell
A novel class of antibiotics based on the antimicrobial properties of immune peptides of multicellular organisms is attracting increasing interest as a major weapon against resistant microbes. It has been claimed that cationic antimicrobial peptides exploit fundamental features of the bacterial cell so that resistance is much less likely to evolve than in the case of conventio...... hiện toàn bộ
Continental cichlid radiations: functional diversity reveals the role of changing ecological opportunity in the Neotropics
Proceedings of the Royal Society B: Biological Sciences - Tập 283 Số 1836 - Trang 20160556 - 2016
Jessica H. Arbour, Hernán López‐Fernández
Adaptive radiations have been hypothesized to contribute broadly to the diversity of organisms. Models of adaptive radiation predict that ecological opportunity and ecological release, the availability of empty ecological niches and the response by adapting lineages to occupy them, respectively, drive patterns of phenotypic and lineage diversification. Adaptive radiations driven by ‘ecolog...... hiện toàn bộ
