Geographical distribution and aspects of the ecology of the hemiparasitic angiosperm Striga asiatica (L) Kuntze: A herbarium study [PDF]

open access: yes, 1997
Striga asiatica (Scrophulariaceae) is an obligate root hemiparasite of mainly C-4 grasses (including cereals). It is the most widespread of the 42 Striga species occurring in many semi-tropical, semi-arid regions of mainly the Old World.

A new Australian species of Luffa (Cucurbitaceae) and typification of two Australian Cucumis names, all based on specimens collected by Ferdinand Mueller in 1856 [PDF]

open access: yes, 2011
As a result of his botanical explorations in northern Australia, Ferdinand von Mueller named several Cucurbitaceae that molecular data now show to be distinct, requiring their resurrection from unjustified synonymy.

A simple and affordable protocol to assess censer seed dispersal: First confirmation of the mechanism in the genus Solanum

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise The censer seed dispersal mechanism, whereby mature fruits are retained on plants and seeds dispersed by mechanical shaking, is among the most specialized wind‐aided seed dispersal strategies employed by the flowering plants. An efficient, affordable, and easily repeatable protocol for determining whether a species uses this unusual ...

Animal‐mediated seed dispersal: A review of study methods

open access: yesApplications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

A curated benchmark dataset for molecular identification based on genome skimming

open access: yesScientific Data
Genome skimming is a promising sequencing strategy for DNA-based taxonomic identification. However, the lack of standardized datasets for benchmarking genome skimming tools presents a challenge in comparing new methods to existing ones.

Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

open access: yesEcography, EarlyView.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...
