Diel Oscillation of Microbial Gene Transcripts Declines With Depth in Oligotrophic Ocean Waters

open access: yesFrontiers in Microbiology, 2019
Diel oscillations in primary and secondary production, growth, metabolic activity, and gene expression commonly occur in marine microbial communities in ocean surface waters.

Spatiotemporal overlap with invasive wild pigs (Sus scrofa) varies by species and season in a temperate ecosystem

open access: yesEcosphere, 2023
Wild pigs (Sus scrofa), which are invasive in many regions globally, can alter ecosystems and compete with native species through interference competition and resource exploitation.

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

open access: yes, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Humans disrupt access to prey for large African carnivores

open access: yeseLife, 2020
Wildlife respond to human presence by adjusting their temporal niche, possibly modifying encounter rates among species and trophic dynamics that structure communities.

Large‐scale evolution of body temperatures in land vertebrates

open access: yesEvolution Letters, 2021
Body temperature is a crucial variable in animals that affects nearly every aspect of their lives. Here we analyze for the first time largescale patterns in the evolution of body temperatures across terrestrial vertebrates (tetrapods: including ...

Diel rhythmicity in amino acid uptake by Prochlorococcus [PDF]

open access: yes, 2008
The marine cyanobacterium Prochlorococcus, the most abundant phototrophic organism on Earth, numerically dominates the phytoplankton in nitrogen (N)-depleted oceanic gyres.

Virus–Host Interactions Drive Contrasting Bacterial Diel Dynamics in the Ocean

open access: yesResearch, 2023
Marine organisms perform a sea of diel rhythmicity. Planktonic diel dynamics have been shown to be driven by light, energy resources, circadian rhythms, and the coordinated coupling of photoautotrophs and heterotrophic bacterioplankton.

Diel variations in the assemblage structure and foraging ecology of larval and 0+ year juvenile fishes in a man-made floodplain waterbody [PDF]

open access: yes, 2016
© 2016 The Fisheries Society of the British Isles. This study investigated diel variations in zooplankton composition and abundance, and the species composition, density, size structure, feeding activity, diet composition and prey selection of larval and

Coordinated Diel Gene Expression of Cyanobacteria and Their Microbiome

open access: yesMicroorganisms, 2021
Diel rhythms have been well recognized in cyanobacterial metabolisms. However, whether this programmed activity of cyanobacteria could elicit coordinated diel gene expressions in microorganisms (microbiome) that co-occur with cyanobacteria and how such ...

Temporal partitioning and the potential for avoidance behaviour within South African carnivore communities

open access: yesEcology and Evolution, 2023
Carnivora occupy many ecological niches fundamental to ecosystem functioning. Within this diverse order, carnivore species compete to establish dominance, ensure survival and maintain fitness. Subordinate carnivores must, therefore, adapt their behaviour
