Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, Volume 2026, Issue 5, May 2026.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, Volume 40, Issue 5, Page 1233-1250, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Characterization of Virulence Genetic Profile and Potential Effect of Nanoparticles against Multidrug-Resistant Uropathogenic E. coli at Menuofia University Hospitals

Journal of Pure and Applied Microbiology
One of the most significant pathogens involved in urinary tract infections is Uropathogenic E. coli (UPEC). In addition to assessing biofilm production and the effect of gold and silver nanoparticles on the isolated strains’ ability to form biofilms, the

Identification of the Integration/Excision Module and Regulatory Elements Involved in the Mobility of IME8, an Integrative and Mobilizable Element From Mosquitocidal Lysinibacillus sphaericus

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
Mosquitocidal genomic island IME8 carries an int‐operon essential for integration/excision and a reg‐operon activating the promoter Pint and repressing excision. Its integration target is present in L. sphaericus and beyond. IME8 and a mini‐IME8 cassette can be mobilized by a conjugative plasmid and display integrating properties into the specific ...
