New Zealand Journal of Botany, Volume 63, Issue 5, Page 1096-1114, December 2025.ABSTRACT Here we present results of the last remaining three, unreported pollen and stratigraphic profiles from our previous investigations on Great Barrier Island from southern Kaitoke. The 14C and pollen data extend the island's previous maximum pollen‐vegetation date from c. 7000 cal. yr BP to close to the end of MIS 3 c. 30,000 cal. yr BP.

Variety in evolutionary strategies favours biodiversity in habitats of moderate productivity [PDF]
, 2011 The mechanism whereby biodiversity varies between habitats differing in productivity is a missing link between ecological and evolutionary theory with vital implications for biodiversity conservation, management and the assessment of ecosystem services ...

Applications in Plant Sciences, Volume 13, Issue 6, November-December 2025.Abstract Premise Analyzing structural changes along the length of an organ provides insight into its development. However, traditional histological methods are limited by intensive procedures and size restrictions. Micro‐computed tomography (microCT) enables non‐destructive internal imaging along the length of an organ, but high cost, technical ...

Invasion impact by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) on a neotropical savanna
Acta Botânica Brasílica, 2015 Whether management intervention is required to control biological invasions depends primarily on demonstrating species losses resulting from such invasions. Brackens of the Pteridium genus are currently regarded as a problem species that act as important

Journal of Phytopathology, Volume 173, Issue 6, November/December 2025.ABSTRACT In July 2021, desert rose plants were consistently observed with symptoms of brown spots on the leaves, which coalesced and promoted leaf fall. The causal agent of the disease was unknown. This study aimed to identify the pathogen responsible for the symptoms through morphological and molecular characterisation, as well as pathogenicity tests.

On mode of rythmological evolution of ferns
Turczaninowia, 2015 Possible ways of rhythmological evolution of ferns are outlined on the basis of comparison of basal evergreen phenorhythmotype with derived rhythms occurring in temperate ferns.

Soil compaction and vegetation cover in a Scots pine stand at the Mediterranean rangelands [PDF]
, 2011 Right development of ROOT SYSTEMS is essential to ensure seedling survival in the initial stages of natural regeneration processes. Soil compaction determines this development both because of its influence on soil Tª & moisture dynamics and for its ...

Natural Apospory in Pteridium?
American 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).

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.Forest elephants need to be conserved not only because they act as forest engineers. They also appear to be self‐medication specialists and could possibly help humans to cope with present and future health issues. Managers should include the development of medicinal leeches to mitigate HEC.
