Navigating the seven seas of arthropod collection protocols: Metabarcoding arthropod diversity in a tropical forest

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2395-2407, October 2025.
Abstract Insects and other arthropods represent one of the most diverse groups of life on Earth, with an estimated 70% of species awaiting discovery. Advances in DNA‐based tools have accelerated species discovery, while high‐throughput sequencing has enabled large‐scale biodiversity surveys.

Los restos que no sobran en el bosque : indagando entre troncos y hojarasca

open access: yesExtensionismo, Innovación y Transferencia Tecnológica, 2016
<p>Los detritos, aunque a veces imperceptibles, son un componente esencial del bosque. Cumplen funciones ecológicas indispensables, como albergar innumerables especies, proveer protección al suelo, regular procesos de ciclado de nutrientes y ser importantes reservorios de carbono y agua. Si bien sabemos que las actividades humanas los alteran, no

Increasingly conservative N cycling in a wet tropical forest: Litter and stream N concentrations decline over 29 years despite surges from hurricanes

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2476-2496, September 2025.
Conceptual model integrating short‐ and long‐term responses of N in litterfall and stream water in a wet tropical forest subject to hurricanes. Despite N surges following hurricanes, N cycling becomes more conservative in the absence of frequent hurricanes.

La tragedia como fundamento estructural de "La Hojarasca"

open access: yesLetras (Lima), 1967
No conocemos ningún trabajo crítico dedicado a “La hojarasca” que atienda al sentido esclarecedor del epígrafe que Gabriel García Márquez pone al comienzo de su novela (…). El único crítico que se detiene brevemente a considerar el epígrafe es Luis Harss, pero en él un simple comentario irónico de la situación: "Y así, como Polinices, perecer el ...

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

open access: yesEcological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.
Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects

open access: yesAnimal Conservation, Volume 27, Issue 5, Page 722-735, October 2024.
Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...

Fertilización artificial aplicado a la conservación de la rana hojarasca desvanciente (Craugastor evanesco)

open access: yesCongreso Nacional de Ciencia y Tecnología – APANAC, 2021
Dentro de los vertebrados, los anfibios representan una clase biológica de gran diversidad que enfrenta la situación más crítica. Existen dificultades dentro de los programas de reproducción en cautiverio que limitan la reproducción exitosa de dichas especies y su posterior reintroducción. La prioridad de establecer programas de conservación ex situ ha

Net primary productivity and litter decomposition rates in two distinct Amazonian peatlands

open access: yesGlobal Change Biology, Volume 30, Issue 8, August 2024.
Our understanding of carbon cycling in tropical peatlands is limited by the lack of data on forest productivity and litter decomposition. Here we present measurements from two floristically distinct Amazonian peatland forests, a palm‐dominated swamp and a thin‐stemmed hardwood swamp.

Multiple‐stressor effects on leaf litter decomposition in freshwater ecosystems: A meta‐analysis

open access: yesFunctional Ecology, Volume 38, Issue 7, Page 1523-1536, July 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Recent years have witnessed a surge in research on the effects of multiple stressors in freshwater ecosystems. While studies have increased, the synthesis of their findings into a broader understanding of ecosystem‐level effects remains an ongoing endeavour. Leaf litter

Tropical forest above‐ground productivity is maintained by nutrients cycled in litter

open access: yesJournal of Ecology, Volume 112, Issue 4, Page 690-700, April 2024.
The maintenance of highly productive lowland tropical forests on infertile soils is often attributed to nutrient cycling via litterfall. Almost 40 years after this theory was first proposed, our large‐scale field experiment demonstrates that tree growth and litter production decline in response to long‐term litter removal, providing the first empirical
