Impacts of land use change on diaspore‐dispersing ant assemblages in southwestern Amazonia

Insect Conservation and Diversity, EarlyView.
Land use changes shift ant assemblages, more intensive land uses are dominated by generalist and open habitat specialist species engaging in group foraging. The diaspore removal rates cannot differ, but the quality of dispersal was lower in disturbed habitats.

Seed development and maturation in early spring-flowering Galanthus nivalis and Narcissus pseudonarcissus continues post-shedding with little evidence of maturation in planta [PDF]

, 2013
Background and Aims: Seeds of the moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus, dispersed during spring or early summer, germinated poorly in laboratory tests.

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

Journal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Fatty acids and glycerides are object recognition and carrying cues for foraging Camponotus modoc carpenter ants

Physiological Entomology, Volume 51, Issue 1, Page 29-39, March 2026.
Colour‐coded perlites were treated with specific fatty acids or mono‐, di‐ or triglycerides as perlite pickup cues for laboratory and field colonies of western carpenter ants. In laboratory and field experiments, ant colonies were offered multiple choices of these colour‐coded lipid‐treated perlites for pickup and transport to the nest.

Seed pretreatment length when producing seeds for restoration may impact seed dormancy in offspring

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Seed dormancy regulates germination timing to improve seedling survival. Many temperate species produce physiologically dormant seeds, requiring winter conditions (i.e. moist‐cold stratification) to overcome dormancy. Exposing seeds to suboptimal stratification lengths for restoration may alter genetic diversity and/or ...
