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

New 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

The physiological resilience of fern sporophytes and gametophytes: advances in water relations offer new insights into an old lineage

Frontiers in Plant Science, 2013
Ferns are some of the oldest vascular plants in existence and they are the second most diverse lineage of tracheophytes next to angiosperms. Recent efforts to understand fern success have fo-cused on the physiological capacity and stress tolerance of ...

Tmesipteris eucampta (Psilotaceae), a newly described species for plants of Tmesipteris from Lord Howe Island

New Zealand Journal of Botany, Volume 63, Issue 5, Page 1506-1517, December 2025.
ABSTRACT Tmesipteris eucampta is described here as a new fern species endemic to Lord Howe Island. Plants of Tmesipteris from Lord Howe Island have long been attributed to T. truncata. However, the elongated and more fusiform synangia and narrowly oblong or narrowly obovate leaves of T.

Phylogenetic analyses place the Australian monotypic Revwattsia in Dryopteris (Dryopteridaceae)

PhytoKeys, 2012
Revwattsia fragilis (Watts) D.L. Jones (Dryopteridaceae), originally described as a Polystichum Roth by the pioneer Australian botanist Reverend W.W. Watts in 1914, is a rare epiphytic fern endemic to northeastern Queensland, Australia. Known from only a

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

New 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.

Germinação de esporos de Polypodium pleopeltifolium: resultados preliminares Polypodium pleopeltifolium spores germination: preliminary results

Acta Botânica Brasílica, 1992
Polypodium pleopeltifolium é uma pteridófíta que ocorre, como epífita, em cerrados do Estado de São Paulo. A espécie é fotoblástica positiva, mas alguns esporos germinam no escuro. Tratamento com aplicações curtas a 40 e 5ºC e temperaturas alternadas não

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti‐herbivore defenses, selection for qualitative toxins, and acceleration of plant–herbivore coevolution

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Cyanogenesis prospection in galled and non-galled tissues of Microgramma squamulosa (Polypodiaceae)

Lilloa, 2020
Cyanogenic glycosides are defense substances that can produce hydrocyanic acid when they undergo hydrolysis as a result of herbivory, a process called cyanogenesis.
