Reproductive behavior of the Red-crested Finch Coryphospingus cucullatus (Aves: Thraupidae) in southeastern Brazil

open access: yesZoologia (Curitiba)
Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests.

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Notes on the nesting biology of five species of Euglossini (Hymenoptera: Apidae) in the Brazilian Amazon

open access: yesEntomoBrasilis, 2017
. The orchid bees (Euglossini) are medium to large-sized species with fully or partially metallic body that are relatively common in the Neotropical Region. Nevertheless, the nesting biology of many species remains unknown.

Studies on aspects of the ecology of some hole nesting birds [PDF]

open access: yes, 1994
The breeding success of four species of small, hole-nesting woodland birds, die Blue, Great and Coal Tits and Pied Flycatcher utilising nestboxes was examined. Three study areas in County Durham were selected, Hamsterley Forest (largely a plantation) and

Dental Microwear Texture Analysis on Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.
