Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Lycophytes and ferns composition of Atlantic Forest conservation units in western Paraná with comparisons to other areas in southern Brazil

Acta Botânica Brasílica, 2015
This study surveyed lycophyte and fern species in four forest fragments in western Paraná, Brazil, and compared them to 15 other fragments with different plant formations from the Atlantic Forest biome in southern Brazil. In total, five lycophyte species

A New Species of Arthropteris From Samoa

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.

Additions to the Fern Flora of Niue (Polynesia): First Records of Ophioglossum lusitanicum L., Ophioderma falcatum (C.Presl) O.Deg. and Psilotum complanatum Sw. and the Disjunct Occurrence of Ophioderma intermedium (Hook.) Nishida

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
During recent field survey for threatened and uncommon vascular plants in Niue, four ferns were collected and confirmed as additions to the indigenous flora. Ophioderma intermedium (Hook.) Nishida and O. falcatum (C.Presl) O.Deg. were collected from terrestrial habitats in primary tropical forest.

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, Volume 8, Issue 6, Page 1572-1587, June 2026.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, Volume 250, Issue 6, Page 3716-3731, June 2026.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Use of Landsat and SRTM Data to Detect Broad-Scale Biodiversity Patterns in Northwestern Amazonia

Remote Sensing, 2012
Vegetation maps are the starting point for the design of protected areas and regional conservation plans. Accurate vegetation maps are missing for much of Amazonia, preventing the development of effective and compelling conservation strategies.

Morpho-Physiological Responses of Shade-Loving Fern Polystichum spp. to Single and Combined Lead and Light Stress

Agronomy
The effects of lead (Pb) stress on plant growth and physiological processes may depend on other environmental stresses coinciding. Knowledge of the response of shade-loving plants to stresses, particularly the relationship between Pb stress and light ...
