Active interventions accelerate native plant recolonization following agricultural abandonment

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our results show that combined canopy thinning and prescribed burning can accelerate natural recolonization in savanna systems. However, additional measures (e.g. seed addition) may be needed for weak‐dispersing species. These findings highlight the utility of integrating passive processes with active interventions to conduct efficient landscape‐scale ...

Forest Plants Decrease in Occupancy and Contract Their Edaphic Niches Towards Their Climatic Range Margins

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 5, May 2026.
ABSTRACT Aim For improved predictions of the redistribution of species under climate change, there is a need to better understand how interactions among multiple abiotic drivers affect species distributions. We examined whether occupancy patterns of forest plant species change consistently along geographic and macroclimatic gradients. We further tested

The life cycles of cryptogams [PDF]

open access: yes, 1991
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

Natural Apospory in Pteridium?

open access: yesAmerican Fern Journal, 1966
From a population of the bracken fern in New Hampshire, Farlow (1889) described prothalloid outgrowths from the marginal sori. He concluded that natural apospory, i.e. the formation of a gametophyte vegetatively from a sporophyte under normal environmental conditions, had occurred as reported by Druery (1884) and Bower (1884).
