Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Pollen morphology of the Stemonaceae

, 1991
A pollen-morphological survey of all four genera of the Stemonaceae at the light and electron microscope level is presented. Stemonaceae is a eurypalynous family. Stichoneuron pollen, up to now described as monosulcate, appears to be inaperturate. Pentastemona pollen is most deviating in Stemonaceae. Its sexine consists of elements that resemble Ubisch

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
