Response of spores and young gametophytes of Cyathea delgadii Sternb. (Cyatheaceae) and Blechnum brasiliense Desv. (Blechnaceae) to different light levels Resposta de esporos e gametófitos jovens de Cyathea delgadii Sternb. (Cyatheaceae) e Blechnum brasiliense Desv. (Blechnaceae) aos diferentes níveis de luz

open access: yesActa Botânica Brasílica, 2007
Light is a limiting factor for fern stablishment because it controls germination of light sensitive spores. The aim of this work was to study the effect of light levels on spore germination in two ornamental ferns native to the Atlantic forest, under ...

Status of forest remnants invaded by tradescantia (Tradescantia fluminensis Vell.) following introduction of biocontrol beetles and manual clearance after three years

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 4, Page 548-572, December 2025.
ABSTRACT We compared biocontrol beetles and manual clearing of tradescantia in forest remnants invaded by tradescantia (Tradescantia fluminensis Vell.) on the agriculturally modified Hikurangi floodplain, northern New Zealand, to inform best practice in enhancing native biodiversity. Four forest remnant study sites were used: two on dairy farms and two

Palynological, tephra, and 14C records from southern Kaitoke, Great Barrier (Aotea) Island, New Zealand, since c. 30,000 cal. yr BP

open access: yesNew 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.

Micro Gondwana: soil and litter mesofauna in the subalpine and alpine of North‐West Nelson, southern New Zealand

open access: yesNew Zealand Journal of Zoology, Volume 52, Issue 5, Page 944-966, December 2025.
ABSTRACT Alpine ecosystems are vulnerable to the warming climate, yet alpine soil mesofauna remains the less studied part of NZ biodiversity. Here we present a survey of soil mesofauna communities of three mountain peaks in the Nelson‐Tasman and Marlborough regions of the South Island of New Zealand.

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia

open access: yesAmerican Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.
