Osteology of the Feeding Apparatus of Chilean Flamingo Phoenicopterus chilensis (Aves: Phoenicopteridae). [PDF]
J Morphol1. The skull features a broad, dorsoventrally flattened frontal region articulating with an elongated upper jaw that is complemented by the mandible's downward bend along its proximal half. 2. The low mechanical advantage in the mandible is attributed to the reduced and shallow insertion areas of the adductor muscles, which are positioned close to the ...

Examining the structure of plant-lemur interactions in the face of imperfect knowledge. [PDF]
Conserv BiolAbstract Biotic interactions, such as plant–animal seed dispersal mutualisms, are essential for ecosystem function. Such interactions are threatened by the possible extinction of the animal partners. Using a data set that includes plant–lemur interactions across Madagascar, we studied the current state of knowledge of these interactions and their ...

Chromosome-scale reference genome of <i>Pectocarya recurvata</i>, the species with the smallest reported genome size in Boraginaceae. [PDF]
Appl Plant SciAbstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.
