Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity

Journal of Applied Entomology, EarlyView.
ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Effects of post‐fire on seed germination and seedling recruitment of a generalist savanna woody species

Plant Biology, EarlyView.
Vegetation type and microclimate shape recruitment of a generalist tree seedling, while fire history alters cotyledon use over time. Abstract Temperature and humidity are key factors influencing seed germination, varying across vegetation types and in response to disturbances such as fire.

Resilience of floral scent emission after florivory

Plant Biology, EarlyView.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Domacios y nectarios extraflorales en Bignoniáceas: componentes vegetales de una interacción mutualística. [PDF]

, 2011
Las plantas presentan relaciones mutualísticas con insectos a cambio del control de sus herbívoros u hongos patógenos; por medio de los domacios les ofrecen albergue y mediante la secreción de néctar de nectarios extraflorales les brindan alimento.

Canopy Definitions Shape Canopy Space Filling–Productivity Relationships: Evidence From Terrestrial Laser Scanning

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The spatial arrangement of trees and their branches within the canopy is crucial for light interception, often resulting in a positive relationship between canopy space filling and stand productivity. To date, there is no universal definition of canopy space.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

Nordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a
