Journal ArticleDOI
Conservation biogeography: assessment and prospect
Robert J. Whittaker,Miguel B. Araújo,Paul Jepson,Richard J. Ladle,James E. M. Watson,Katherine J. Willis +5 more
TL;DR: The role played by biogeographical science in the emergence of conservation guidance is examined and the case for the recognition of Conservation Biogeography as a key subfield of conservation biology delimited as both a substantial body of theory and analysis is made.
Journal ArticleDOI
Chlorophyll a fluorescence as a tool to monitor physiological status of plants under abiotic stress conditions
Hazem M. Kalaji,Anjana Jajoo,Abdallah Oukarroum,Marian Brestic,Marek Zivcak,Izabela A. Samborska,Magdalena D. Cetner,Izabela Łukasik,Vasilij Goltsev,Richard J. Ladle,Richard J. Ladle +10 more
TL;DR: The results of fast ChlF analyses of photosynthetic responses to environmental stresses are reviewed, the potential scientific and practical applications of this innovative methodology are discussed, and the recent availability of portable devices has significantly expanded the potential utilization of Chlf techniques.
Journal ArticleDOI
Seven Shortfalls that Beset Large-Scale Knowledge of Biodiversity
Joaquín Hortal,Francesco de Bello,José Alexandre Felizola Diniz-Filho,Thomas M. Lewinsohn,Jorge M. Lobo,Richard J. Ladle +5 more
TL;DR: The concept of knowledge shortfalls is updated and the tradeoffs between generality and uncertainty are reviewed and a general framework for the combined impacts and consequences of shortfalls of large-scale biodiversity knowledge is concluded.
Journal ArticleDOI
ORIGINAL ARTICLE: A general dynamic theory of oceanic island biogeography
TL;DR: A general dynamic model (GDM) of oceanic island biogeography that aims to provide a general explanation of biodiversity patterns through describing the relationships between fundamental biogeographical processes – speciation, immigration, extinction – through time and in relation to island ontogeny is presented.
Journal ArticleDOI

TL;DR: Practical information on the hardware, methodology, and the hands on application of chlorophyll (Chl) a fluorescence technology is provided to scientists who have some experience with the application but are still in the process of discovering what it all means and how it can be used.
