Wherefore the Magic? The Evolutionary Role of Psilocybin in Nature

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study explores the evolutionary role of psilocybin, the psychedelic compound found in Psilocybe mushrooms. We provide the first experimental tests of defence and community‐level evidence for invertebrate responses to psilocybin‐producing fungi, revealing significant negative effects on invertebrate locomotion, development, and survival.

Expression of the KNOTTED HOMEOBOX Genes in the Cactaceae Cambial Zone Suggests Their Involvement in Wood Development [PDF]

, 2017
The vascular cambium is a lateral meristem that produces secondary xylem (i.e., wood) and phloem. Different Cactaceae species develop different types of secondary xylem; however, little is known about the mechanisms underlying wood formation in the ...

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, Volume 2026, Issue 4, April 2026.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Cactaceae em um fragmento florestal urbano de Vila Velha, Espírito Santo, Brasil

Paubrasilia, 2020
Cactaceae é uma família quase que exclusivamente endêmica do Novo Mundo. No estado do Espírito Santo, Brasil, a família é pouco amostrada e inventários florísticos de seus representantes são escassos.

Multiple Community Properties Drive Ecosystem Resistance and Resilience to Extreme Climate Events Across Mesic Grasslands

Ecology Letters, Volume 29, Issue 4, April 2026.
Using nearly 40 years of data from naturally‐assembled plant communities, we found that while richness is important for resistance to extreme dry events, dominance is important for resistance to extreme wet events and evenness is important for resilience.

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages

New Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.
Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in
