Revista de Biología Tropical, 2010 The phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes ...

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

Ecology 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%.

Biotropica, 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
Land 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.

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador
Ecology and Evolution, Volume 16, Issue 8, August 2026.We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Solar System constraints to nonminimally coupled gravity
, 2013 We extend the analysis of Chiba et al. [Phys. Rev. D 75, 124014 (2007)] of Solar System constraints on f(R) gravity to a class of nonminimally coupled (NMC) theories of gravity. These generalize f(R) theories by replacing the action functional of general
