Bridging a biogeographic 'gap' : microfossil evidence for the quillwort Isoetes on the Cumberland Plain west of Sydney during the early Colonial period [PDF]

open access: yes, 2013
Fossil spores preserved on historical archaeological sites at Parramatta and Richmond indicate that two or more species of the quillwort genus Isoetes (family Isoetaceae) were growing along rivers on the Cumberland Plain, west of Sydney, during the late ...

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

Larvicidal potential of Cyathea species against Culex quinquefasciatus

open access: yesPharmaceutical and Biomedical Research, 2017
Resistance to insecticides has persuaded researchers to find new methods to control Culex quinquefasciatus proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.

Biodiversity and spatial distribution of epiphytic ferns on Alsophila setosa Kaulf. (Cyatheaceae) caudices in Rio Grande do Sul, Brazil

open access: yesBrazilian Journal of Biology
The extractive exploitation of the tree fern Alsophila setosa Kaulf. alters forest formations and diminishes the availability of micro-habitat for epiphytes. A survey of epiphytic fern communities on A.

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

Nitrogen transfer from nitrogen-fixing lichen to co-occurring epiphytes in the subtropical forests of Yunnan

open access: yesGuangxi Zhiwu
Acquiring sufficient nitrogen(N)to meet requirements for growth is a major challenge for epiphytes living in nutrient-poor canopy habitats. Cyanolichens(lichens that contain cyanobacterial symbionts)can function as the primary participants in biological ...

Comparing vegetative effects of domestic stock and feral goats as ungulate herbivores in Waingaro: Year 1 results [PDF]

open access: yes, 2006
Fencing remnant native vegetation has become a widespread activity throughout New Zealand to increase native biodiversity. However, there have not been many studies to show if this is an effective approach when feral goats (Capra hircus) are present. The

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

open access: yesBoreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.
