From Cactus to Composite: Thermo‐Mechanical Analysis of Opuntia Fibers and Insights for Potential Composite Material Applications

Polymers for Advanced Technologies, Volume 36, Issue 9, September 2025.
ABSTRACT In this work, Opuntia (commonly called prickly pear cactus) was investigated as a source for reinforcing plant fibers, as it represents a low‐cost and widely available alternative to other commonly used natural fibers, such as kenaf, hemp, sisal, or flax.

Consumption of Prickly Pear Cactus Flowers by Melanoplus occidentalis: A Coevolutionary Association? [PDF]

Environmental Entomology, 1992
A study of the association between Melanoplus occidentalis (Thomas) and the prickly pear cactus, Opuntia polyacantha Haw., was conducted on native rangeland in southeastern Wyoming. During the study, the grasshopper population density was 14.5 ± 3.7 m-2, of which 52% were M. occidentalis in cactus patches and 16%were M.

Isolating the role of the matrix at patch and landscape scales

Journal of Animal Ecology, Volume 94, Issue 9, Page 1800-1810, September 2025.
This is the first experimental test of the spatial scales of matrix effects. Both patch‐scale and landscape‐scale matrix influence populations through a cross‐scale interaction altering survival, reproduction, and movement. Conservation in fragmentated landscapes should consider the matrix context of patches while focusing on local matrix due to its ...

Phytochemical and Antioxidant Profile of Pitaya (Hylocereus hybridum) Fruits: Elucidation Through Chemical Fractionation

Journal of Food Science, Volume 90, Issue 8, August 2025.
ABSTRACT The increasing global demand for diverse and health‐promoting foods has led to the expansion of tropical fruit cultivation beyond their native regions, notably into the Mediterranean area. This shift necessitates a deeper understanding of their phytochemical profiles, as environmental factors in new cultivation contexts can significantly ...

Loss of Paired Weapons Leads to Larger Testes and a Lighter Load for Dispersal

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We addressed a weapons testes trade‐off using natural limb loss as an experimental manipulation of weaponized legs in the leaf‐footed cactus bug. We found that individuals missing weapons invested in their testes proportional to the number of weaponized legs they lost.

Harley's Course—Integrating Teachings From Western and Indigenous Sciences in an Undergraduate Biology Course

Ecology and Evolution, Volume 15, Issue 7, July 2025.
This paper describes a relational land‐based learning experiential field course that bridges Western and Indigenous scientific worldviews. We describe the impact of incorporating traditional Indigenous paradigms and knowledge into post‐secondary science curriculum and the challenges inherent in decolonizing Western science.

Multi‐Species Impacts of Invasive Opuntia Cacti on Mammal Habitat Use

Ecology Letters, Volume 28, Issue 7, July 2025.
Biological invasions impact ecosystems worldwide, including through changing the behaviour of native species. Here, we used camera traps to investigate the effects of invasive Opuntia spp. on the habitat use of 12 mammal species in an internationally important region of mammalian biodiversity.
