The stepwise rise of angiosperm‐dominated terrestrial ecosystems

open access: yesBiological Reviews, EarlyView.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

An Angiosperm species dataset reveals relationships between seed size and two-dimensional shape [PDF]

open access: yes, 2019
Datasets containing information on seed size have been published and are currently available. Nevertheless, there is a lack in the literature of a dataset dedicated to seed shape. We present a preliminary version for a dataset on seed morphology based on

Reversibility of sex changes in the plant kingdom: more important than we thought?

open access: yesBiological Reviews, EarlyView.
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...

The family classification of the New Caledonian angiosperms has become more stable with the application of the APG system

open access: yesCladistics, EarlyView.
Abstract The era of molecular systematics has had a tremendous impact on taxonomy, with the increasing availability of phylogenetic trees allowing the recircumscription of higher taxa, particularly through the application of the monophyletic principle.

Intratumoural tigilanol tiglate in the multicentre treatment of equine sarcoids and cutaneous melanomas

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Intralesional chemotherapeutic administration represents an important treatment option for equine cutaneous neoplasia. Tigilanol‐tiglate (TT), a novel molecule extracted from Fontainea picrosperma, an Australian rainforest plant, is registered for intratumoural treatment of canine MCT, leading to rapid oncosis and tumour slough ...

Beyond Deception: What Else Do Flower Wasps (Hymenoptera: Thynnidae: Thynninae) Do in Flowers Worldwide?

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Wasps, although less recognised as good pollinators, also feed on nectar and pollinate flowers. Specialised pollination systems, such as orchids that mimic the pheromones of female wasps to attract males, are complex and specific. This interaction occurs with some Thyninnae wasps that also visit flowers to obtain nectar and perform other ...

The targeted metabolomic profile of laticifers in rubber tree

open access: yesJournal of Integrative Plant Biology, EarlyView.
Targeted metabolomic profiling of rubber tree (Hevea brasiliensis) laticifers identified metabolites that were reprogramming by domestication, revealed active isoprenoid metabolism in the laticifers, and discovered loci with potential biosynthetic applications, supporting the potential of developing laticifers as bioreactors for production of valuable ...

Dioecy in a wind‐pollinated herb explained by disruptive selection on sex allocation via inbreeding avoidance

open access: yesNew Phytologist, EarlyView.
Summary The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both. It has hitherto been difficult to uncouple the importance of these two hypotheses.
