Mixed Bat-Hummingbird Pollination Assures Reproductive Success in a Highly Variable Upper Montane Species. [PDF]
Ecol EvolWe investigated the reproductive biology of Callianthe sellowiana, a high‐altitude Atlantic Forest species with traits associated with both bat and hummingbird pollination. Our results show that both pollinator groups are equally effective, and reproductive success is enhanced when both are present, highlighting the functional and temporal ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology
Austral Ecology, Volume 51, Issue 6, June 2026.ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.

Beyond Bergmann and Allen: A Unified Framework for Thermoregulatory Morphology
Global Ecology and Biogeography, Volume 35, Issue 6, June 2026.ABSTRACT Context Ecogeographical rules such as Bergmann's and Allen's have long guided expectations about how organismal size and shape vary across temperature gradients. Yet these rules are typically tested independently despite sharing a common thermoregulatory basis.

Parasitoidism of Chalcidid wasps (Hymenoptera, Chalcididae) on Philornis sp. (Diptera, Muscidae)
Brazilian Journal of BiologyPhilornis Meinert larvae are known as parasites of birds, with coprophagous, semi-hematophagous or hematophagous habits. Biological data of the larvae of the fifty described species are still scarcely known.
