Freshwater biodiversity: importance, threats, status and conservation challenges Tập 81 Số 2 - Trang 163-182 - 2006
David Dudgeon, Angela H. Arthington, Mark O. Gessner, Zen’ichiro Kawabata, Duncan Knowler, Christian Lévêque, Robert J. Naiman, Anne‐Hélène Prieur‐Richard, Doris Soto, Melanie L. J. Stiassny, Caroline A Sullivan
ABSTRACTFreshwater biodiversity is the over‐riding conservation priority during
the International Decade for Action ‐‘Water for Life’ ‐ 2005 to 2015. Fresh
water makes up only 0.01% of the World's water and approximately 0.8 % of the
Earth's surface, yet this tiny fraction of global water supports at least 100
000 species out of approximately 1.8 million ‐ almost 6% of all described
species. Inlan... hiện toàn bộ
Effect size, confidence interval and statistical significance: a practical guide for biologists Tập 82 Số 4 - Trang 591-605 - 2007
Shinichi Nakagawa, Innes C. Cuthill
AbstractNull hypothesis significance testing (NHST) is the dominant statistical
approach in biology, although it has many, frequently unappreciated, problems.
Most importantly, NHST does not provide us with two crucial pieces of
information: (1) the magnitude of an effect of interest, and (2) the precision
of the estimate of the magnitude of that effect. All biologists should be
ultimately interes... hiện toàn bộ
Integrating animal temperament within ecology and evolution Tập 82 Số 2 - Trang 291-318 - 2007
Denis Réale, Simon M. Reader, Daniel Sol, Peter T. McDougall, Niels J. Dingemanse
AbstractTemperament describes the idea that individual behavioural differences
are repeatable over time and across situations. This common phenomenon covers
numerous traits, such as aggressiveness, avoidance of novelty, willingness to
take risks, exploration, and sociality. The study of temperament is central to
animal psychology, behavioural genetics, pharmacology, and animal husbandry, but
relat... hiện toàn bộ
REPRODUCTIVE and LARVAL ECOLOGY OF MARINE BOTTOM INVERTEBRATES Tập 25 Số 1 - Trang 1-45 - 1950
Gunnar Thorson
Summary1. In analysing the ecological conditions of an animal population we have
above all to focus our attention upon the most sensitive stages within the life
cycle of the animal, that is, the period of breeding and larval development.2.
Most animal populations on the sea bottom maintain the qualitatively composition
of the species composing them, over long periods of time, though the individual... hiện toàn bộ
Repeatability for Gaussian and non‐Gaussian data: a practical guide for biologists Tập 85 Số 4 - Trang 935-956 - 2010
Shinichi Nakagawa, Holger Schielzeth
Repeatability (more precisely the common measure of repeatability, the
intra‐class correlation coefficient, ICC) is an important index for quantifying
the accuracy of measurements and the constancy of phenotypes. It is the
proportion of phenotypic variation that can be attributed to between‐subject (or
between‐group) variation. As a consequence, the non‐repeatable fraction of
phenotypic variation ... hiện toàn bộ
Emerging threats and persistent conservation challenges for freshwater biodiversity Tập 94 Số 3 - Trang 849-873 - 2019
Andrea J. Reid, Andrew K. Carlson, Irena F. Creed, Erika J. Eliason, Peter Gell, Pieter T. J. Johnson, Karen A. Kidd, Tyson J. MacCormack, Julian D. Olden, S. J. Ormerod, John P. Smol, William W. Taylor, Klement Tockner, Jesse C. Vermaire, David Dudgeon, Steven J. Cooke
ABSTRACTIn the 12 years since Dudgeon et al. (2006) reviewed major pressures on
freshwater ecosystems, the biodiversity crisis in the world's lakes, reservoirs,
rivers, streams and wetlands has deepened. While lakes, reservoirs and rivers
cover only 2.3% of the Earth's surface, these ecosystems host at least 9.5% of
the Earth's described animal species. Furthermore, using the World Wide Fund for
N... hiện toàn bộ
Bivariate line‐fitting methods for allometry Tập 81 Số 2 - Trang 259-291 - 2006
David I. Warton, Ian J. Wright, Daniel S. Falster, Mark Westoby
ABSTRACTFitting a line to a bivariate dataset can be a deceptively complex
problem, and there has been much debate on this issue in the literature. In this
review, we describe for the practitioner the essential features of line‐fitting
methods for estimating the relationship between two variables: what methods are
commonly used, which method should be used when, and how to make inferences from
the... hiện toàn bộ
Landscape moderation of biodiversity patterns and processes ‐ eight hypotheses Tập 87 Số 3 - Trang 661-685 - 2012

Ewers, Jochen Fründ, Robert D. Holt, Andrea Holzschuh, Alexandra‐Maria Klein, David Kleijn, Claire Kremen, Doug Landis, William F. Laurance, David B. Lindenmayer, Christoph Scherber, Navjot S. Sodhi, Ingolf Steffan‐Dewenter, Carsten Thies, Wim H. van der Putten, Catrin Westphal
Understanding how landscape characteristics affect biodiversity patterns and
ecological processes at local and landscape scales is critical for mitigating
effects of global environmental change. In this review, we use knowledge gained
from human‐modified landscapes to suggest eight hypotheses, which we hope will
encourage more systematic research on the role of landscape composition and
