Going solo: discovery of the first parthenogenetic gordiid (Nematomorpha: Gordiida). [PDF]
PLoS ONE, 2012 Despite the severe fitness costs associated with sexual reproduction, its persistence and pervasiveness among multicellular organisms testifies to its intrinsic, short-term advantages.

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.

Mixed Mating System Are Regulated by Fecundity in Shorea curtisii (Dipterocarpaceae) as Revealed by Comparison under Different Pollen Limited Conditions. [PDF]
PLoS ONE, 2015 The maintenance of mixed mating was studied in Shorea curtisii, a dominant and widely distributed dipterocarp species in Southeast Asia. Paternity and hierarchical Bayesian analyses were used to estimate the parameters of pollen dispersal kernel, male ...

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]
, 2016 PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Exposure to Endocrine Disruptors and Nuclear Receptors Gene Expression in Infertile and Fertile Men from Italian Areas with Different Environmental Features [PDF]
, 2015 Internal levels of selected endocrine disruptors (EDs) (i.e., perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), di-2-ethylhexyl-phthalate (DEHP), mono-(2-ethylhexyl)-phthalate (MEHP), and bisphenol A (BPA)) were analyzed in blood/serum of ...

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 ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]
, 2005 Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

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.
