Adaptive capabilities, pathdependence and institutional change: insights from an empirical work on rural producers organizations [PDF]

, 2007
During the last twenty years, the evolution of public policies in Southern countries has been characterized by the implementation of liberalization processes, which can be analyzed through Douglass North's institutional change approach.

Disentangling Multitrophic Interactions: How Vegetation Cover, Wild Boar, Deer, and Predators Shape Rodents Activity and Acorn Dispersal

Integrative Zoology, EarlyView.
Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.

STOCHASTIC SIMULATION FOR BUFFELGRASS (Cenchrus ciliaris L.) PASTURES IN MARIN, N. L., MEXICO

Tropical and Subtropical Agroecosystems, 2014
A stochastic simulation model was constructed to determine the response of net primary production of buffelgrass (Cenchrus ciliaris L.) and its dry matter intake by cattle, in Marín, NL, México.

Calibration of the species threat abatement and restoration metric's threat abatement component in a Costa Rican landscape

Conservation Biology, EarlyView.
Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Spanish agricultural production and productivity, 1890-1936 [PDF]

, 1995
In the first section new estimates for final agricultural output between 1892 and 1936 are presented. These indicate that only from 1909/13 did land and labour productivity start to increase.

Telomere Length Is Determined by Intrinsic Factors and Is Shortened During Drought Years in Gallotia galloti

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Telomere dynamics in ectotherms remain poorly understood relative to endotherms, yet are increasingly relevant in the context of climate change. Here, we used model‐averaged GLMMs and hierarchical partitioning to disentangle intrinsic and extrinsic drivers of relative telomere length in the Western‐Canaries Lizard (Gallotia galloti) across a 10‐year ...

Short‐term effects of wildlife rehabilitation disappear over time in the wild: A case study on Spanish imperial eagles

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
We assessed the effectiveness of Wildlife Recovery Centers by comparing dispersal behavior of rehabilitated and wild Spanish imperial eagles using GPS tracking. Rehabilitated individuals initially moved shorter distances, rested more, and hunted less than wild controls, but these differences declined over time and ultimately disappeared.

NUMBER OF COWS AND BAGS NEEDED TO ESTIMATE in situ DRY MATTER DEGRADATION OF KINGGRASS (Pennisetum purpureum) LEAVES

Tropical and Subtropical Agroecosystems, 2012
The number of bags to be incubated per sample, and the number of fistulated cows needed to estimate in situ ruminal degradation of Kinggrass (Pennisetum purpureum) dry matter (DMD %) were determined. Three rumen-fistulated cows and 10 bags per incubation
