Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae)

open access: yesBMC Evolutionary Biology, 2019
Background Tropical rainforests (TRFs) harbour almost half of the world’s vascular plant species diversity while covering only about 6–7% of land. However, why species richness varies amongst the Earth’s major TRF regions remains poorly understood.

Leaf dimorphism of Microgramma squamulosa (Polypodiaceae): a qualitative and quantitative analysis focusing on adaptations to epiphytism

open access: yesRevista de Biología Tropical, 2013
The epiphytic fern Microgramma squamulosa occurs in the Neotropics and shows dimorphic sterile and fertile leaves. The present study aimed to describe and compare qualitatively and quantitatively macroscopic and microscopic structural characteristics of ...

Biomechanical consequences of epiphytism in intertidal macroalgae

open access: yes, 2013
Summary: Epiphytic algae grow on other algae rather than hard substrata, perhaps circumventing competition for space in marine ecosystems.

Epiphytism across a megadiverse pteridoflora

open access: yesRevista Peruana de Biología
Ferns and lycophytes represent the second largest epiphytic group of vascular plants. Here we examined herbaria collection and literature to provide an account of epiphytes for Peru’s pteridoflora. We assessed compositional differences related to geography, altitudinal distribution, and vegetation type, along with observations on endemism and ...

Evidence for a Cenozoic radiation of ferns in an angiosperm-dominated canopy.

open access: yes, 2020
In today's angiosperm-dominated terrestrial ecosystems, leptosporangiate ferns are truly exceptional--accounting for 80% of the approximately 11,000 nonflowering vascular plant species.

Radicular anatomy of twelve representatives of the Catasetinae subtribe (Orchidaceae: Cymbidieae)

open access: yesAnais da Academia Brasileira de Ciências, 2012
Considering that the root structure of the Brazilian genera belonging to the Catasetinae subtribe is poorly known, we describe the roots of twelve representatives from this subtribe.

Bioactivity of Secondary Metabolites from Macroalgae

open access: yes, 2015
International audienceIn intertidal ecosystem, biotic (reproduction stage, algal growth, herbivory, epiphytism, fouling…) and abiotic (temperature, salinity, UV…) parameters are known to affect the algal species repartition. In response to this stresses,
