Ecological implications of reduced pollen deposition in alpine plants: a case study using a dominant cushion plant species [v1; ref status: indexed, http://f1000r.es/3mb]

F1000Research, 2014
The reproductive assurance hypothesis states that self-incompatible female plants must produce twice the number of seeds relative to their self-compatible hermaphroditic counterparts to persist in gynodioecious populations.

Temporal changes in the most effective pollinator of a bromeliad pollinated by bees and hummingbirds [PDF]

PeerJ, 2020
A generalist pollination system may be characterized through the interaction of a plant species with two or more functional groups of pollinators. The spatiotemporal variation of the most effective pollinator is the factor most frequently advocated to ...

Bees may drive the reproduction of four sympatric cacti in a vanishing coastal mediterranean-type ecosystem [PDF]

PeerJ, 2019
Background Sympatric congeneric plants might share pollinators, or each species might avoid competition by evolving specialized traits that generate partitions in pollinator assemblages.

Aging Regulated Through a Stability Model of Insulin/Insulin Growth Factor Receptor Function

Frontiers in Endocrinology, 2021
Mutations of the insulin-like receptor in Drosophila extend lifespan. New research suggests this receptor operates in two modes. The first extends lifespan while slowing reproduction and reducing growth.

Reproductive assurance through self-fertilization does not vary with population size in the alien invasive plant Datura stramonium

, 2007
Autonomous self-fertilization is suggested to be associated with invasiveness in plants because it offers reproductive assurance when there is a shortage of suitable mates or pollinators.

Why Self-fertilizing Plants Still Exist in Wild Populations: Diversity Assurance through Stress-Induced Male Sterility May Promote Selective Outcrossing and Recombination

Agronomy, 2020
Climate change creates challenges for wild species, but plants have survived and adapted to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical genetic reason being that self-fertilization does not create ...

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...
