Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

How Epiphytic Are Epiphytes? Field Evidence for Flexible Substrate Use in Tropical Cloud Forest Plants

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
In the field, 63% of the species grew exclusively epiphytically, while 37% also grew terrestrially. Literature‐derived epiphytic values consistently overestimated substrate fidelity relative to field observations, particularly single‐source classifications, with mean absolute differences of up to 32%.

Methodological Effects on Plant–Hummingbird Networks: A Comparison of Pollen Load and Focal Observation Approaches in Colombian Andean Ecosystems

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Ecological interactions, such as plant–pollinator interactions, are fundamental to maintaining biodiversity and sustaining ecosystem functions. In tropical ecosystems, hummingbirds serve as key pollinators due to their specialized morphological traits, which facilitate plant–pollinator interactions.

Underground Lag: Fungal Community and Edaphic Legacies After Disturbance

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 9266-9279, 15 August 2026.
ABSTRACT Páramos are neotropical mountain ecosystems that regulate water and store large amounts of carbon, but are increasingly degraded by agriculture and grazing. Although native vegetation often recolonizes after abandonment, belowground recovery remains poorly understood.
