We compared the abundance and characteristics of trees in replicated plots across a rural to urban gradient in Guanacaste, Costa Rica. Trees in urban parks, fencerows, and national parks provide complementary benefits and have distinct compositions.

Desarrollo de estructura laminar del suelo en siembra directa [PDF]
La siembra directa (SD) es en la actualidad el principal sistema de manejo de suelos de la Argentina, y en particular de la Región Pampeana. Su adopción trajo aparejada una modificación de la estructura del suelo y de las propiedades físicas. Uno de los efectos más llamativos es el desarrollo de estructura laminar (EL) superficial, que fue observado ...

Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

En el Ecuador tradicionalmente los ingenieros estructurales, diseñan las estructuras considerando bases empotradas, asumiendo rigidez infinita del suelo, lo que es una metodología poco apegada a la realidad, debido a que el suelo presenta deformaciones ...

Soil degassing at Ustica Island: Comparison between 1997 and 1999 surveys
Se hicieron dos estudios de gas del suelo y de flujos de CO2 y CH4, en la Isla Ustica (arco sur del Mar Tirreno) en 1997 y 1999, para examinar el rol del degasamiento de sistemas de falla y fractura como una evidencia local de estructuras mayores de ...

Beyond species means – the intraspecific contribution to global wood density variation
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.
