100 years of tropical bryophyte and lichen ecology : a bibliographic guide to the literature from 1901 - 2000 [PDF]

open access: yes, 2002
A list of 401 citations pertaining to the ecology of tropical bryophytes and lichens is presented. The bibliography includes publications addressing the biology, ecology, natural history, and physiology of bryophytes and lichens, but generally eschews ...

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Bacillus sp. G2112 Detoxifies Phenazine-1-carboxylic Acid by N5 Glucosylation

open access: yesMolecules
Microbial symbionts of plants constitute promising sources of biocontrol organisms to fight plant pathogens. Bacillus sp. G2112 and Pseudomonas sp. G124 isolated from cucumber (Cucumis sativus) leaves inhibited the plant pathogens Erwinia and Fusarium ...

An updated classification of growth forms in non‐geniculate coralline algae (Corallinophycidae, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be

Quantifying the abundance of four large epiphytic fern species in remnant complex notophyll vine forest on the Atherton Tableland, north Queensland, Australia [PDF]

open access: yes, 2013
Epiphytes are generally considered rare in complex forests on the western edge of the Atherton Tablelands, north Queensland. This assertion is based on comparisons with wetter forests in the Wet Tropics bioregion, but is of limited use in restoration ...

Elucidating Epiphyte Diversity [PDF]

open access: yesScience, 2011
Ecology![Figure][1] CREDIT: A. M. BENAVIDES In tropical forests, an important fraction of the total plant species diversity is composed of epiphytes: plants that are rooted for part or all their life on the trunks and branches of trees and lianas.

Temporal stability and spatial patterns of genetic diversity in populations of the climate‐vulnerable fucoid Scytothalia dorycarpa

open access: yesJournal of Phycology, EarlyView.
Abstract Climate change is driving the loss of genetic diversity, potentially limiting species' capacity to adapt to environmental change. Detecting changes in genetic diversity requires replicated temporal data, which is lacking for most species. Here, we combined contemporary and historical specimens of the climate‐vulnerable fucoid Scytothalia ...
