Beetle Pollination of Cycads in the Mesozoic
, 2018 Cycads, unlike modern wind-pollinated conifers and Ginkgo, are unusual in that they are an ancient group of gymnosperms pollinated by insects [1–3]. Although it is well documented that cycads were diverse and abundant during the mid-Mesozoic, little is ...

Biodiversity and Food Security in Sub‐Saharan Africa: Evidence From a Dynamic Spatial Durbin Model
Plant-Environment Interactions, Volume 7, Issue 6, December 2026.ABSTRACT This study examines the effect of biodiversity on food security in 40 Sub‐Saharan African countries over the period 2001–2022. Food security is measured using a composite Food Security Index constructed through Principal Component Analysis, while biodiversity is proxied by the Red List Index.

American Journal of Botany, Volume 113, Issue 10, October 2026.Abstract Premise The study of the early stages of divergence between populations is crucial to understanding how species and biodiversity originate. Geographic distributions that capture some aspects of the process of divergence, such as those that are markedly U‐shaped, could offer a window to identify systems undergoing incipient speciation, which ...

Stem Carbon Dioxide Efflux of Lignophytes Exceeds That of Cycads and Arborescent Monocots
Agronomy, 2022 Tree stem CO2 efflux (Es) can be substantial and the factors controlling ecosystem-level Es are required to fully understand the carbon cycle and construct models that predict atmospheric CO2 dynamics.

Clinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.ABSTRACT Background Robotic computer‐assisted implant surgery (r‐CAIS) aims to improve implant placement trueness, but existing reviews include heterogeneous designs, and no review has exclusively synthesized RCTs to date. This review aimed to evaluate the positional trueness and clinical outcomes of r‐CAIS compared with free‐hand implant surgery (FHIS)

The Future of Native Bees in Australia Under Environmental and Anthropogenic Change
Ecology and Evolution, Volume 16, Issue 10, October 2026.Bees are considered one of the most important and abundant pollinators across the globe, yet they are under threat from anthropogenic activities such as land‐clearing, urbanisation, agricultural activities, pesticide use, non‐native flora and fauna introductions, disruption of natural fire regimes, pollution and climate change, among others.

Relational knowing as method and practice
People and Nature, Volume 8, Issue 10, Page 3585-3600, October 2026.Abstract This paper seeks to contribute to (re)building the capacity for embodied, place‐based relational knowing, transforming how we know and thus what we know. What is known, or sought to be known, is relations. How we know these relations is by already being in it: breathing, sensing, moving, listening, responding, affecting and being affected ...
