A Framed Field Experiment on Collective Enforcement Mechanisms with Ethiopian Farmers [PDF]
, 2008 We present the results of a framed field experiment with Ethiopian farmers that use the mountain rain forest as a common pool resource. Harvesting honey causes damage to the forest, and open access leads to overharvesting.

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts
Advanced Science, EarlyView.We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.

TIMBER HARVEST ADJACENCY ECONOMIES, HUNTING, SPECIES PROTECTION, AND OLD GROWTH VALUE: SEEKING THE OPTIMUM [PDF]
Spatial forest management models recognize that nontimber benefits cat1 be influenced by the status of adjacent land. For instance, contiguous old growth provides habitat, aesthetic value, and environmental services. Conversely, edge areas provide forage

Advanced Science, EarlyView.In pancreatic ductal adenocarcinoma (PDAC), insulin is associated with activation of PI3K/AKT–RAB3A signaling and enhanced secretion of TNFAIP8‐enriched exosomes from tumor cells. Uptake of these exosomes by fibroblasts is linked to TRIM21‐dependent STAT1 degradation and the emergence of myofibroblastic CAF–associated features, accompanied by increased

Advanced Science, EarlyView.We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Harvester and Forwarder machines efficiency and operational performance in forest harvesting
Pesquisa Agropecuária Tropical, 2012 The knowledge on productive capacity and variable elements that affect machines efficiency is essential for optimizing operations in forest harvesting. This study aimed to evaluate Harvester and Forwarder machines efficiency and operational performance, for forest exploitation, in the south of the Bahia State, Brazil.

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1
Advanced Science, EarlyView.Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

The environmental resource curse hypothesis: the forest case [PDF]
The resource curse hypothesis relies on the resource-rich countries tendency to grow slower than resource-poor countries. Focusing on forest issues, this paper extends the resource curse hypothesis to environmental degradation: how do forest endowment ...

Planning horizons and end conditions for sustained yield studies in continuous cover forests
, 2014 The contemporary forestry preoccupation with non-declining even-flow during yield simulations detracts from more important questions about the constraints that should bind the end of a simulation.
