Disturbance and diversity in experimental microcosms

diversity

Buckling A, Kassen R, Bell G, Rainey PB.
GSID: Z8etVcZQbF8J
A Buckling, R Kassen, G Bell, PB Rainey - Nature, 2000 - nature.com

… Our results show that disturbance can modulate the effect of spatial heterogeneity on biological diversity in natural environments. … that diversity in the paired SM–WS populations was indeed greatest at intermediate disturbance (F 2,33 = 5.20, P <...

Diversity peaks at intermediate productivity in a laboratory microcosm

diversity

Bell G, Buckling A, Kassen R, Rainey PB.
GSID: rgcudxGZ6FIJ
R Kassen, A Buckling, G Bell, PB Rainey - Nature, 2000 - nature.com

The species diversity of natural communities is often strongly related to their productivity. The pattern of this relationship seems to vary: diversity is known to increase monotonically …

A taxonomic review of the Selenophori group (Coleoptera, Carabidae, Harpalini) in the West Indies, with descriptions of new species and notes about classification and biogeography.

ZooKeys

Shpeley D, Hunting W, Ball GE.
PMID: 29118595
Zookeys. 2017 Aug 16;(690):1-195. doi: 10.3897/zookeys.690.13751. eCollection 2017.

Primarily a taxonomic review of the West Indian elements of the selenophorine Harpalini, this paper includes a classification, a key, descriptions and illustrations of taxa, re-rankings, and new synonymies. In total, 45 species and subspecies are treated, six of...

An unknown quantity--the worldwide prevalence of epilepsy.

Epilepsia

Bell GS, Neligan A, Sander JW.
PMID: 24964732
Epilepsia. 2014 Jul;55(7):958-62. doi: 10.1111/epi.12605. Epub 2014 Jun 25.

The reported incidence (rate of new cases in a population) of epilepsy is consistently lower in high-income than in lower-income economies, whereas opinions vary regarding comparative prevalence rates (proportion of the population with epilepsy). For any condition that does...

Hamstring/Quadriceps Strength Ratios in Collegiate Middle-Distance and Distance Runners.

The Physician and sportsmedicine

Morris A, Lussier L, Bell G, Dooley J.
PMID: 27442470
Phys Sportsmed. 1983 Oct;11(10):71-7. doi: 10.1080/00913847.1983.11708658.

In brief: It has been noted that the hamstring/quadriceps isometric strength ratio in men should be approximately 50% to 60%. We studied hamstring/quadriceps strength ratios in collegiate varsity middle-distance runners and found that they varied between.62 at slow speeds...

Nest inundation from sea-level rise threatens sea turtle population viability.

Royal Society open science

Pike DA, Roznik EA, Bell I.
PMID: 26587269
R Soc Open Sci. 2015 Jul 22;2(7):150127. doi: 10.1098/rsos.150127. eCollection 2015 Jul.

Contemporary sea-level rise will inundate coastal habitats with seawater more frequently, disrupting the life cycles of terrestrial fauna well before permanent habitat loss occurs. Sea turtles are reliant on low-lying coastal habitats worldwide for nesting, where eggs buried in...

High-Precision Half-Life Measurements for the Superallowed β^{+} Emitter ^{10}C: Implications for Weak Scalar Currents.

Physical review letters

Dunlop MR, Svensson CE, Ball GC, Grinyer GF, Leslie JR, Andreoiu C, Austin RA, Ballast T, Bender PC, Bildstein V, Diaz Varela A, Dunlop R, Garnsworthy AB, Garrett PE, Hackman G, Hadinia B, Jamieson DS, Laffoley AT, MacLean AD, Miller DM, Mills WJ, Park J, Radich AJ, Rajabali MM, Rand ET, Unsworth C, Valencik A, Wang ZM, Zganjar EF.
PMID: 27176517
Phys Rev Lett. 2016 Apr 29;116(17):172501. doi: 10.1103/PhysRevLett.116.172501. Epub 2016 Apr 28.

Precision measurements of superallowed Fermi β-decay transitions, particularly for the lightest superallowed emitters ^{10}C and ^{14}O, set stringent limits on possible scalar current contributions to the weak interaction. In the present work, a discrepancy between recent measurements of the...

Precise half-life measurement for the superallowed 0(+)-->0(+) beta emitter (74)Rb: first results from the new radioactive beam facility (ISAC) at TRIUMF.

Physical review letters

Ball GC, Bishop S, Behr JA, Boisvert GC, Bricault P, Cerny J, D'Auria JM, Dombsky M, Hardy JC, Iacob V, Leslie JR, Lindner T, Macdonald JA, Mak HB, Moltz DM, Powell J, Savard G, Towner IS.
PMID: 11290166
Phys Rev Lett. 2001 Feb 19;86(8):1454-7. doi: 10.1103/PhysRevLett.86.1454.

Presently, the world data for superallowed beta decay leads to a result in disagreement (at the 98% confidence level) with the predictions of the minimal standard model for the unitarity of the Cabibbo-Kobayashi-Maskawa matrix. Precise data for the superallowed...

The Distribution of Abundance in Neutral Communities.

The American naturalist

Bell G.
PMID: 10777433
Am Nat. 2000 May;155(5):606-617. doi: 10.1086/303345.

The patterns of abundance generated by a simple stochastic birth-death-immigration model are described in order to characterize the diversity of neutral communities of ecologically equivalent species. Diversity is described by species number S and the variance of frequency or...
