Low siring success of females with an acquired male function illustrates the legacy of sexual dimorphism in constraining the breakdown of dioecy

open access: yes, 2019
12 Pág.Dioecy has often broken down in flowering plants, yielding functional hermaphroditism. We reasoned that evolutionary transitions from dioecy to functional hermaphroditism must overcome an inertia of sexual dimorphism, because modified males or ...

Resolution of Levodopa/Dopa‐Decarboxylase Inhibitor—Associated Microscopic Colitis with Subcutaneous Foslevodopa/Foscarbidopa: A Case Series and Review of the Literature

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Microscopic colitis (MC) typically presents with chronic, non‐bloody watery diarrhea. Diagnosis requires endoscopy with colonic mucosal biopsies. The etiology is multifactorial, with several medications implicated, although only a few cases have been attributed to oral levodopa/dopa‐decarboxylase inhibitor (LDDCI) therapy.

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Evidence for dispersal personality in the guppy across ecological conditions, with a minor effect of relative brain size

open access: yesOikos, EarlyView.
Individuals that disperse typically exhibit specific phenotypical traits that facilitate dispersal and settlement success, known as ‘dispersal syndromes'. Consequentially, characterizing dispersers is crucial to understand other processes such as metapopulation dynamics and biological invasions.

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...
