A morphogenetic study of sporangia-partitioning complex
Acta Societatis Botanicorum Poloniae, 2015 The bilobed sporangia in the species of Anthoceros, Isoetes and Ophioglossum are described. The morphogenetic importance of the process of "fission" in evolutionary development of sporangia in pteridophytes is discussed.

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.Wild boars that have recently arrived in Port‐Cros National Park are reducing the reproductive success of Yelkouan shearwaters by destroying nests and predating on eggs and chicks. In the absence of measures to control the wild boar population, this would likely accelerate the decline of the Yelkouan shearwater population.

Nordic Journal of Botany, Volume 2026, Issue 7, July 2026.Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.

Phylogenomics indicates the "living fossil" Isoetes diversified in the Cenozoic.
PLoS ONE, 2020 The fossil record provides an invaluable insight into the temporal origins of extant lineages of organisms. However, establishing the relationships between fossils and extant lineages can be difficult in groups with low rates of morphological change over

Freshwater habitats within the Natura 2000 network
Ecological Applications, Volume 36, Issue 3, April 2026.Abstract Freshwater biodiversity is experiencing dramatic declines. Despite improvements, the trend remains negative, underlining that effective and coordinated initiatives are needed. Protected areas are considered a global cornerstone of biodiversity conservation, and in Europe, the Natura 2000 network plays a central role in safeguarding ...

Environmental DNA, Volume 8, Issue 2, March/April 2026.Bryophyte‐targeted primers captured a longer DNA fragment, moving beyond the indirect “bycatch” approach using vascular plant primers. This improved detection and recovered greater bryophyte diversity, with substantial overlap with taxa obtained through bycatch.

The role of Alpine botanical gardens in integrating germplasm bank collections and mission
PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

Isoetes in Alaska and the Aleutians
American Fern Journal, 1999 Three species of Isoetes are recognized as present in the study area: I. echinospora Durieu (diploid, 2n=22), I. maritima Underw. (tetraploid, 2n=44) and I. occidentalis L.F. Hend. (hexaploid, 2n=66). Three interspecific hybrids are expected and two are known to be present: I. xpseudotruncata D.M. Britton & D.F.
