Notes on (Convolvulaceae) from Ecuador.

Fieldwork, examination of herbarium specimens and photographic images, supported by molecular sequencing have resulted in the re-interpretation of a number of species of L. found in Ecuador and the recognition of four new species. Standl.

Phytochemical profiling, antioxidant, enzymatic inhibitory, and antibacterial activities of .

, a member of the Namaceae family, is a source of metabolites and has been traditionally used as an anti-inflammatory. This work aimed to determine the total phenolic content (TPC), total flavonoid content (TFC), antioxidant effect, inhibition of α-glucosidase and cholinesterase enzymes (AChE, BChE), and antibacterial activity of the methanolic extract (ME) and subfractions of . The findings revealed that ME and its subfractions exhibited significant antioxidant capacity, with the ethyl acetate fraction being the most active, displaying an IC of 17.

Refuting the hypothesis of Centinelan extinction at its place of origin.

Scientists' limited understanding of tropical plant communities obscures the true extent of species loss caused by habitat destruction. The Centinelan extinction hypothesis posits an extreme but widely referenced scenario wherein forest clearing causes the immediate extinction of species known only from a single geographic location. It remains unclear, however, whether the disappearance of such microendemics reflects their global extinction or insufficient collection effort at larger scales.

When the absence of evidence is not the evidence of absence: (Loasaceae) rediscoveries from Peru and Ecuador, and the contribution of community science networks.

Documentation of plant taxa has long been subject to the temporal and spatial selectivity of professional research expeditions, especially in tropical regions. Therefore, rare and/or narrowly endemic species are sometimes known only from very few and very old herbarium specimens. However, these taxa are very important from a conservation perspective.

Re-establishment of the genus (Leguminosae, Caesalpinioideae, mimosoid clade): the New World species formerly placed in .

Following recent mimosoid phylogenetic and phylogenomic studies demonstrating the non-monophyly of the genus , we present a new molecular phylogeny focused on the neotropical species in the genus, with much denser taxon sampling than previous studies. Our aims were to test the monophyly of the neotropical section Arthrosamanea, resolve species relationships, and gain insights into the evolution of fruit morphology. We perform a Bayesian phylogenetic analysis of sequences of nuclear internal and external transcribed spacer regions and trace the evolution of fruit dehiscence and lomentiform pods.

Hypopigmentation in mantled howler monkeys (gray 1849): First documented cases of whole-body leucism in South America.

The existence of hypopigmentation like leucism is the result of genetic anomalies that might be enhanced by external factors such as pollution. This anomaly may reduce survival rates. Leucism has been recorded in wildlife, but overall, it is considered very rare.

Rediscovery of L.E.Skog & L.P.Kvist (Gesneriaceae) at multiple sites in western Ecuador.

We report the rediscovery of the Critically Endangered cloud forest herb , not seen since 1985. In 2019 and 2021, was recorded at five sites in the western foothills of the Ecuadorian Andes, 4-25 km from the type locality at the celebrated Centinela ridge. We describe the species' distribution, abundance, habitat and conservation status and offer recommendations for further research and conservation efforts focused on and the small, disjunct forest remnants it occupies.
