Complex life-cycles in trophically transmitted helminths: Do the benefits of increased growth and transmission outweigh generalism and complexity costs?
Autor: Daniel P. Benesh, James C. Chubb, Kevin D. Lafferty, Geoff A. Parker
Publikováno v: Current Research in Parasitology and Vector-Borne Diseases, Vol 2, Iss , Pp 100085- (2022)
Why do so many parasitic worms have complex life-cycles? A complex life-cycle has at least two hypothesized costs: (i) worms with longer life-cycles, i.e. more successive hosts, must be generalists at the species level, which might reduce lifetime su

A comparative test of the gamete dynamics theory for the evolution of anisogamy in Bryopsidales green algae
Autor: Tatsuya Togashi, Yusuke Horinouchi, Geoff A. Parker
Publikováno v: Royal Society Open Science, Vol 8, Iss 3 (2021)
Gamete dynamics theory proposes that anisogamy arises by disruptive selection for gamete numbers versus gamete size and predicts that female/male gamete size (anisogamy ratio) increases with adult size and complexity. Evidence has been that in volvoc

Endless forms of sexual selection
Autor: Willow R. Lindsay, Staffan Andersson, Badreddine Bererhi, Jacob Höglund, Arild Johnsen, Charlotta Kvarnemo, Erica H. Leder, Jan T. Lifjeld, Calum E. Ninnes, Mats Olsson, Geoff A. Parker, Tommaso Pizzari, Anna Qvarnström, Rebecca J. Safran, Ola Svensson, Scott V. Edwards
Publikováno v: PeerJ, Vol 7, p e7988 (2019)
In recent years, the field of sexual selection has exploded, with advances in theoretical and empirical research complementing each other in exciting ways. This perspective piece is the product of a “stock-taking” workshop on sexual selection and

How Soon Hath Time… A History of Two 'Seminal' Publications
Autor: Geoff A. Parker
Publikováno v: Cells, Vol 10, Iss 2, p 287 (2021)
This review documents the history of the two papers written half a century ago that relate to this special issue of Cells. The first, “Sperm competition and its evolutionary consequences in the insects” (Biological Reviews, 1970), stressed that s

Quantitative kinetic modelling and mapping of cerebral glucose transport and metabolism using glucoCESL MRI
Autor: Ben R Dickie, Tao Jin, Ping Wang, Rainer Hinz, William Harris, Hervé Boutin, Geoff JM Parker, Laura M Parkes, Julian C Matthews
Publikováno v: Journal of Cerebral Blood Flow & Metabolism. 42:2066-2079
Chemical-exchange spin-lock (CESL) MRI can map regional uptake and utilisation of glucose in the brain at high spatial resolution (i.e sub 0.2 mm3 voxels). We propose two quantitative kinetic models to describe glucose-induced changes in tissue R1ρ
