Turnover of Putrescine in a Pseudomonas Species [PDF]

open access: yesJournal of Bacteriology, 1972
A Pseudomonas species was found to readily take up labeled putrescine added in trace amounts to any of four growth media, bis-(3-aminopropyl)-amine, 4-aminobutyrate, glucose-NH 3 , and Casamino Acids, although the rate of uptake varied considerably from one medium to another.

Rewiring of peatland plant–microbe networks outpaces species turnover [PDF]

open access: yesOikos, 2020
Enviro–climatic changes are thought to be causing alterations in ecosystem processes through shifts in plant and microbial communities; however, how links between plant and microbial communities change with enviro–climatic change is likely to be less straightforward but may be fundamental for many ecological processes.

Quantifying multiple-site compositional turnover in an Afrotemperate forest, using zeta diversity

open access: yesForest Ecosystems, 2018
Background Species turnover is typically measured by partitioning diversity components into alpha and pairwise beta diversity. However, alpha and beta components cannot express the full spectrum of multiple-site compositional turnover.

Introgression and rapid species turnover in sympatric damselflies [PDF]

open access: yesBMC Evolutionary Biology, 2011
Studying contemporary hybridization increases our understanding of introgression, adaptation and, ultimately, speciation. The sister species Ischnura elegans and I. graellsii (Odonata: Coenagrionidae) are ecologically, morphologically and genetically similar and hybridize. Recently, I.

Beyond similarity: A network approach for identifying and delimiting biogeographical regions [PDF]

open access: yes, 2014
Biogeographical regions (geographically distinct assemblages of species and communities) constitute a cornerstone for ecology, biogeography, evolution and conservation biology.

Species turnover across different life stages from seedlings to canopy trees in swamp forests of Central Brazil [PDF]

open access: yes, 2015
Processes driving the assembly of swamp forest communities have been poorly explored. We analyzed natural regeneration and adult tree communities data of a swamp gallery forest in Central Brazil to discuss the role of ecological filters in shaping plant ...

Waders (Aves, Charadriiformes) in a Mediterranean remnant wetland: a year-round pilot study evidences contrasting patterns in diversity metrics

open access: yesRivista Italiana di Ornitologia - Research in Ornithology, 2015
Around a yearly cycle (August 2011 - July 2012), we studied the assemblages of waders (Aves Charadriiformes) occurring in a Mediterranean remnant wetland, obtaining a set of diversity metrics.

Environmental Drivers of Mesophotic Echinoderm Assemblages of the Southeastern Pacific Ocean

open access: yesFrontiers in Marine Science, 2021
Mesophotic ecosystems (50–400 m depth) of the southeastern Pacific have rarely been studied because of the logistical challenges in sampling across this remote zone. This study assessed how oxygen concentrations and other environmental predictors explain

Cross-species Comparison of Proteome Turnover Kinetics

open access: yesMolecular & Cellular Proteomics, 2018
The constitutive process of protein turnover plays a key role in maintaining cellular homeostasis. Recent technological advances in mass spectrometry have enabled the measurement of protein turnover kinetics across the proteome. However, it is not known if turnover kinetics of individual proteins are highly conserved or if they have evolved to meet the
