Effect of environmental factors on the abundance variations of two native rodents in agricultural systems of Buenos Aires, Argentina [PDF]

, 2019
Our aim was to assess the effect of environmental factors on short temporal abundance variations of the two most abundant native rodents of agricultural agroecosystems, Akodon azarae and Calomys laucha.

Parental experiences orchestrate locust egg hatching synchrony by regulating nuclear export of precursor miRNA

Nature Communications
Parental experiences can affect the phenotypic plasticity of offspring. In locusts, the population density that adults experience regulates the number and hatching synchrony of their eggs, contributing to locust outbreaks.

Accumulation of DNA damage alters microRNA gene transcription in Arabidopsis thaliana

BMC Plant Biology, 2022
Background MicroRNAs (miRNAs) and other epigenetic modifications play fundamental roles in all eukaryotic biological processes. DNA damage repair is a key process for maintaining the genomic integrity of different organisms exposed to diverse stresses ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Comparison of predation by two suburban cats in New Zealand [PDF]

, 2017
To study the effects domestic cats may have on surrounding wildlife, a complete list was made of 558 items caught in the garden or brought into the house by one cat over 17 years, from 1988 to 2005.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

GAF-dependent chromatin plasticity determines promoter usage to mediate locust gregarious behavior

The EMBO Journal
Locusts, as devastating pests, can reversibly transform between solitary individuals and gregarious swarms with markedly different behaviors. Epigenetic regulation orchestrated by changes in chromatin openness modulates behavioral plasticity by ...
