Impacts of invasive weed Chromolaena odorata on growth and development of threatened native tree Aegle marmelos under water stress conditions

open access: yesJournal of Ecology and Environment
Background: The invasive weed Chromolaena odorata has been pronounced in dry habitats in Nepal, where a threatened native tree Aegle marmelos prefers to grow. It is known that the allelochemicals from C.

Multiplicity of species in some replicative systems [PDF]

open access: yesPhys.Rev.E 61, 3009 (2000), 1999
In an attempt to explain the uniqueness of the coding mechanism of living cells as contrasted with multi-species structure of ecosystems we examine two models of individuals with some replicative properties. In the first model the system generically remains in a multi-species state.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Global assessment of critical forest and landscape restoration needs for threatened terrestrial vertebrate species

open access: yesGlobal Ecology and Conservation, 2020
Habitat restoration will prove critical if we are to reverse current population declines and extinction rates of Threatened species. This is particularly the case for forest restoration, given that >80% of Threatened species live in forests and they are ...

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis

open access: yesFEBS Open Bio, EarlyView.
Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.
