Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

Ecological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation

Progress in the study of dioecy in Mexican cycad species and its implications for conservation

Plant Species Biology, Volume 40, Issue 6, Page 556-571, November 2025.
Cycads are endangered dioecious plants of great ornamental value that have a long period of sexual maturity. Therefore, it is crucial to have methods for early sex determination that can help to develop effective strategies for their conservation. Abstract Dioecy is a system of sexual reproduction in plants, characterized by the spatial separation of ...

Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

Ecography, Volume 2025, Issue 9, September 2025.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.
