Contrasting Osmotic Stress Responses and Provenance Effects on Seed Germination and Seedling Performance in Two Andean Species. [PDF]

Plant Environ Interact
Oreocallis grandiflora was highly drought‐sensitive, whereas Salvia corrugata recovered and showed adaptive traits. Provenance effects were strong in O. grandiflora but weak in S. corrugata. These results reveal species‐ and provenance‐dependent responses to water limitation, highlighting the importance of selecting suitable species and seed sources ...

Anatomical Behaviour of the Phrenic Nerve and Innervation of the Diaphragm in the Maned Wolf (Chrysocyon brachyurus). [PDF]

Anat Histol Embryol
ABSTRACT The phrenic nerve is responsible for the motor innervation of the diaphragm, which is essential for breathing. The literature lacks data regarding the nervous and respiratory systems of wild animals, especially the maned wolf (Chrysocyon brachyurus).

The Role of Habitat, Climate, and Space in the Species and Traits Variation of Phytoplankton in Large Cascade Reservoirs. [PDF]

Ecol Evol
Phytoplankton beta diversity along cascade reservoirs of the Tocantins River is shaped by reservoir age, spatial arrangement, and environmental conditions. Younger, distant reservoirs show higher diversity, while intermediate ones tend toward homogenization. Environmental and spatial drivers differentially influence taxonomic and functional composition.
