A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Intersexuality in the porcellanid crab Pisidia longicornis (Crustacea: Decapoda: Anomura: Porcellanidae)

open access: yesZoologia (Curitiba), 2015
Intersex specimens of Pisidia longicornis (Linnaeus, 1767) are recorded for the first time and their secondary sexual characters are analyzed. Of 145 specimens of P. longicornis examined in this study, six were identified as intersex individuals.

MicroRNA‐130a‐3p Targets the Androgen‐Related Transcription Factor MAFB: Effects on Proliferation, Migration, Apoptosis, and Cell Cycle in Hypospadias

open access: yesPediatric Discovery, EarlyView.
MicroRNA‐130a‐3p targets and inhibits MAFB expression, leading to the development of hypospadimas. MicroRNA‐130a‐3p inhibits the expression of MAFB, disrupts the normal processes of cell proliferation, migration, cell apoptosis, and cycle progression, and ultimately leads to the development of hypospadias.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...
