Feeding ecology of hummingbirds in the Serra do Mar, southeastern Brazil
El Hornero, 1986 The feeding behaviour of hummingbirds was studied in November and December 1983 at Boracéia, an area of very humid forest in the Serra do Mar, SE Brazil at 800-900 m.

The Anatomical Record, EarlyView.Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Plant-hummingbird interactions and temporal nectar availability in arestinga from Brazil
Anais da Academia Brasileira de Ciências, 2015 Hummingbirds are the most important and specialized group of pollinating birds in the Neotropics and their interactions with plants are key components to many communities.

Land birds on atolls: diversity, origin, and function
Biological Reviews, EarlyView.ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Dispersal‐limited birds at high risk from cattle farming deforestation in tropical forests
Oikos, EarlyView.Deforestation driven by farming is a major threat to tropical biodiversity. Although this impact is well documented, assessments at local or regional scales often underestimate biodiversity loss at broader national scales by up to 60%. A key question remains: how do farming activities affect functional diversity and species traits across different ...

Niche‐tracking as a collecting method: Habitat‐targeted search strategies for taxon‐focused botany
PLANTS, PEOPLE, PLANET, EarlyView.Biodiversity science depends on more than collecting plants—it depends on how we search for them. Although GPS and digital maps have transformed fieldwork, they can also encourage repeated visits to the same easy‐to‐access sites, leaving other habitats and populations unknown to science.

A Systematic Review of Participatory Science Approaches in K–12 Ecological Monitoring
Science Education, EarlyView.ABSTRACT Participatory science has emerged as a vital educational approach for engaging K–12 learners in authentic scientific inquiry while generating data for ecological monitoring. This systematic review synthesizes 72 empirical studies published between 2006 and 2025 that involved K–12 students in ecological monitoring projects.
