Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

open access: yesPeople and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Data gaps and heterogeneity limit our understanding of human–wildlife interactions: A continental study of Andean bears

open access: yesPeople and Nature, EarlyView.
Abstract The expansion and intensification of human activities have increased interactions between people and wildlife. Interactions involving bears and other large carnivores are complex and can lead to conflicts. Promoting positive coexistence requires managing information, which is not always available.

Poly(L‐Lactide‐Co‐ε‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

open access: yesPolymer Composites, EarlyView.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...

Investigation on Impact Behavior of Thermoplastic Composites: A Ply‐Level Numerical Methodology for Impact‐Resistance Design

open access: yesPolymer Composites, EarlyView.
Experimental and numerical investigation on impact‐tolerance efficient evaluation of soft TPU composites. ABSTRACT This study combines experimental characterization and numerical modeling to investigate the impact behavior of aramid fiber–reinforced composites incorporating a thermoplastic polyurethane (TPU) matrix. Low‐velocity impact (LVI) tests were

Enhancing the Properties of PA6 and PA6/Ionomer Scraps Blend With CaCO3 Nanoparticles: Rheological, Mechanical, Thermal, and Morphological Evaluation

open access: yesPolymer Engineering &Science, EarlyView.
ABSTRACT This study investigated the effects of incorporating ionomer scraps and CaCO3 nanoparticles on the rheological, mechanical, thermal, and morphological properties of neat polyamide 6 (PA6) and a PA6/ionomer scraps (80/20) blend. The ionomer formed an immiscible dispersed phase within the PA6, acting as an impact modifier; however, it reduced ...
