Succession is threatening the large population of Lycopodiella inundata (L.) Holub. on anthropogenic site [PDF]

Ecological Questions, 2016
Lycopodiella inundata is an endangered, wetland species, able to occur in secondary, anthropogenic habitats. The article presents five-year changes in the occurrence of Lycopodiella inundata on the one of the largest stands in Central Poland. Chosen parameters of population were examined in different stages of vegetation succession. In open thickets

Natural products and extracts from plants as natural UV filters for sunscreens: A review. [PDF]

Animal Model Exp Med, 2023
It summarized natural UV filters from plant in the last 6 years in types of major constituent, main biological effects, evaluation methods of UV radiation resistance, anti‐UV radiation experiment models and anti‐UV radiation mechanisms, in order to better understand the role of herbal extracts in exerting their photo protective activity.

Is there silicon in flowers and what does it tell us? [PDF]

Ecol Evol, 2023
Whether flowers accumulate Si and what the implications may be was largely unknown. We analysed the flowers separated into their different anatomical parts, and leaves of different taxa. We conclude that flowers contain Si, in large amounts for some species, and hence the function of this element warrants more attention.

Scrub encroachment promotes biodiversity in temperate European wetlands under eutrophic conditions. [PDF]

Ecol Evol, 2022
We examine the effects of encroachment on biodiversity along gradients of soil moisture and soil fertility in open and wooded wetlands in Denmark. Our results support existing knowledge of the importance of nutrient poor, wet mires and meadows for rare species but on former arable lands where restoration of infertile habitats is less feasible we ...

Isolation of cholinesterase and β-secretase 1 inhibiting compounds from Lycopodiella cernua

Bioorganic & Medicinal Chemistry, 2015
Three new serratene-type triterpenoids (1-3) and a new hydroxy unsaturated fatty acid (13) together with nine known compounds (4-12) were isolated from Lycopodiella cernua. The chemical structures were established using NMR, MS, and Mosher's method. Compound 13 showed the most potent inhibitory activity against acetylcholinesterase (AChE) with an IC50 ...

Histological analysis of indirect somatic embryogenesis in the Marsh clubmoss Lycopodiella inundata (L.) Holub (Pteridophytes)

Plant Science, 2000
An efficient in vitro plant regeneration method was developed for Lycopodiella inundata (L.) Holub, an endangered medicinal Lycopod (Pteridophytes). Vegetative apices were used as explant material. Nodular calluses were established after three cycles (13 weeks each) on a medium containing a few minerals and organic compounds and supplemented with 0.05 ...

Techniques for locating and analyzing subterranean Lycopodium and Diphasiastrum gametophytes in the field. [PDF]

Appl Plant Sci, 2022
Abstract Homosporous club mosses have an archaic life cycle, alternating two locationally, nutritionally, and physiologically independent generations. The sexual generation of club mosses—the gametophytes (or prothallia)—are among the least researched botanical subjects.

Adaptive plant traits under anthropogenic burning regimes: A database for UK heath and mire plant species. [PDF]

Am J Bot
Abstract Premise Humans have used fire to manage landscapes for millennia, but this use of fire is declining in many ecosystems. Understanding how plants respond to these changes is key to predicting ecosystem resilience and impacts on services such as biodiversity and carbon sequestration. However, many ecosystems lack data on plant fire responses.
