ALTURAS DE MACCHU PICCHU

Acta Herediana, 2014
Sube a nacer conmigo, hermano. Dame la mano desde la profunda zona de tu dolor diseminado. No volverás del fondo de las rocas. No volverás del tiempo subterráneo. No volverá tu voz endurecida. No volverán tus ojos taladrados. Mírame desde el fondo de la tierra, labrador, tejedor, pastor callado, domador de guanacos tutelares, albañil del andamio ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Risk factors associated with owner‐reported sleep disturbances in Nordic horses

Equine Veterinary Journal, Volume 58, Issue 3, Page 728-735, May 2026.
Abstract Background Very little is known about sleep disturbances in horses, although several management or animal‐based factors may contribute to an increased risk of disturbances. Objectives To investigate factors related to rest and sleep behaviour of horses kept in stalls as perceived by Nordic horse owners or caretakers and their association with ...
