Ecology and evolution of facilitation among symbionts

open access: yesNature Communications, 2018
Facilitation occurs when one species positively impacts the fitness of another, and has predominantly been studied in free-living species like plants.

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Characterization of CRISPR-Cas Systems in Serratia marcescens Isolated from Rhynchophorus ferrugineus (Olivier, 1790) (Coleoptera: Curculionidae) [PDF]

open access: yes, 2019
The CRISPR-Cas adaptive immune system has been attracting increasing scientific interest for biological functions and biotechnological applications. Data on the Serratia marcescens system are scarce.

A niche perspective on the range expansion of symbionts

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2019
Range expansion results from complex eco‐evolutionary processes where range dynamics and niche shifts interact in a novel physical space and/or environment, with scale playing a major role. Obligate symbionts (i.e.

Identifying knowledge gaps about context dependency in freshwater species invasions

open access: yesOikos, EarlyView.
The abiotic template of freshwater ecosystems is being altered by human activity on a global scale, often promoting the establishment of new invasive taxa and increasing the likelihood of facilitation between invaders. These positive interactions represent a substantive threat to freshwater ecosystems by promoting the establishment and persistence of ...

The diversity and ecological role of protozoa in fresh waters [PDF]

open access: yes, 1997
Protozoa feed on and regulate the abundance of most types of aquatic microorganisms, and they are an integral part of all aquatic microbial food webs. Being so small, aerobic protozoa thrive at low oxygen tensions, where they feed (largely unaffected by ...

As you weed, so shall you reap: on the origin of algaculture in damselfish [PDF]

open access: yes, 2010
Within their territories, damselfish cultivate particular algae for consumption. A recent study in BMC Evolutionary Biology shows extensive variation among and within fish species in the composition of these algal 'gardens', varying from monocultures to ...

Evolution of host support for two ancient bacterial symbionts with differentially degraded genomes in a leafhopper host

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Nutritional symbionts in sap-feeding insects are characterized by highly degenerate genomes. It is poorly understood how hosts evolve to maintain these symbionts, particularly when hosts rely on more than one symbiont that requires distinct ...

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions

open access: yesOikos, EarlyView.
Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

Genomic analysis of co-infection with Wolbachia and Candidatus Tisiphia in the sand fly Sergentomyia squamirostris

open access: yesFrontiers in Microbiology
IntroductionEndosymbiotic bacteria show diverse strategies to manipulate host reproduction for their survival in nature. The diversity of symbionts infecting hematophagous insects and their impact on host ecology could be crucial for developing effective
