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
<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

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"
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 ...

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
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 ...

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
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
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
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
