Insect Conservation and Diversity, EarlyView.Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Revista de la Facultad de Agronomía, 2020 El pecán [Carya illinoinensis (Wangenh.) K. Koch] se desarrolla en Argentina desde mediados del siglo XX, aunque su interés resurgió en los últimos años impulsado por el importante dinamismo que experimentó el comercio mundial de los frutos secos.

New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Biotropica, Volume 58, Issue 4, July 2026.Forest cover within cattle ranches can strongly shape faunal biodiversity. In Los Tuxtlas, Veracruz, Mexico. We show that butterflies, moths, dung beetles, and birds respond differently to forest cover across habitats (pastures vs. forest fragments) and seasons, as a function of their specialization and resource needs.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars
Functional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity
Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.
