Orchid conservation: how can we meet the challenges in the twenty-first century?
Botanical Studies, 2018 With c. 28,000 species, orchids are one of the largest families of flowering plants, and they are also one of the most threatened, in part due to their complex life history strategies.

Bark water storage capacity influences epiphytic orchid preference for host trees.
American-Eurasian journal of botany, 2020 PREMISE Of all orchid species described, 70% live on phorophytes. Trees offer a vital space with characteristics that influence the successful establishment and life cycle of orchids.

American Journal of Botany, EarlyView.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.

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]
, 2013 The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization
Ecography, EarlyView.Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Anther mimicry in an African orchid pollinated by pollen-feeding beetles. [PDF]
Plant Biol (Stuttg)Beetles chew the fleshy yellow tips of an orchid's petals and pollinate its flowers, representing a novel case of pollen‐seeking beetles being deceived through anther mimicry. Abstract Flowers of many species have yellow markings that appear to mimic anthers or pollen and attract the attention of pollen‐seeking insects (usually female bees).

The Dark Side of Orchid Symbiosis: Can Tulasnella calospora Decompose Host Tissues?
International Journal of Molecular Sciences, 2020 Photosynthetic orchids associate with mycorrhizal fungi that can be mostly ascribed to the “rhizoctonia” species complex. Rhizoctonias’ phylogenetic diversity covers a variety of ecological/nutritional strategies that include, beside the symbiosis ...

Speciation, dispersal and the build‐up of fern diversity in the American tropics
Ecography, EarlyView.Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overlooked speciation, a critical driver of species richness, and insufficiently accounted for temporal changes in ...
