Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Fungal Biodiversity From the Atlantic Forest With Bioactive Metabolites Against Cutaneous Leishmaniasis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Biodiversity offers a rich source of bioactive compounds for drug discovery. We isolated Aspergillus fumigatus from compost in the Atlantic Forest and found its extract active against Leishmania (Leishmania) amazonensis. Two crude extracts, I06 and I75, were selected for further study.

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

A test of the mycorrhizal-associated nutrient economy framework in two types of tropical rainforests under nutrient enrichments

Forest Ecosystems, 2023
Shifts in tree species and their mycorrhizal associations driven by global change play key roles in biogeochemical cycles. In this paper, we proposed a framework of the mycorrhizal-associated nutrient economy (MANE), and tested it using nutrient addition
