A proximodistal gradient in bone structure and mechanics in the wings of Seba's short‐tailed bat, Carollia perspicillata

open access: yesThe Anatomical Record, EarlyView.
Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Secondary Metabolites Composition and Their Histochemical Localization in the Fruit of Piper malgassicum Papini, Palchetti, Gori and Rota Nodari (Piperaceae)

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The anatomy, histochemistry, and secondary metabolite composition were investigated on the drupes of Piper malgassicum, one of the components of the spice voatsiperifery pepper. The high amount of piperine recorded with high‐performance liquid chromatography with photodiode‐array detection analysis was localized with histochemistry mainly ...

Characterization of the Cubamyces Menziesii Terpenome

open access: yesChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Muriqui House: conservation management to support the recovery of the northern muriqui Brachyteles hypoxanthus in Ibitipoca, Minas Gerais, Brazil

open access: yesOryx
Ensuring the demographic and genetic viability of small populations of threatened primates requires a range of management approaches. Here we describe a novel mixed in situ and ex situ management project that was developed to restore a population of the ...

Scalogram habitat measures as predictors of bird abundance

open access: yesEcography, EarlyView.
Birds select habitat characteristics, such as variability in habitat structure, across multiple spatial scales (grain and extent). Measuring habitat variability at multiple scales can better capture factors that influence avifauna communities than focusing on one scale only. One valuable tool in assessing habitat heterogeneity is the cumulative dynamic

Taxon cycles in Neotropical mangroves

open access: yesPlants, 2022
AbstractThe concept of taxon cycle involves successive range expansions and contractions over time through which a species can indefinitely maintain its core distribution. Otherwise, it becomes extinct. Taxon cycles have been defined mostly for tropical island faunas, examples from continental areas are scarce and similar case studies for plants remain
