The significance of vegetation, fire and man in the stabilisation of sand dunes near the Warburton Ranges, Central Australia [PDF]

open access: yes, 1971
The vegetation cover of sand dunes and sandplain country in a part of Central Australia is aperiodically destroyed by fire, caused by lightning and Aboriginal activities.

Saltation transport on Mars

open access: yes, 2007
We present the first calculation of saltation transport and dune formation on Mars and compare it to real dunes. We find that the rate at which grains are entrained into saltation on Mars is one order of magnitude higher than on Earth.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

The missing piece of the puzzle: A new and widespread species of the genus Rhynchocalamus Günther, 1864 (Squamata, Colubridae) from the Arabian Peninsula [PDF]

open access: yesZoosystematics and Evolution
Discovery rates of new species are uneven across taxonomic groups and regions, with distinctive and widely distributed species being more readily described than species with secretive habits.

Navigating Market Constraints: Sustainable Startups Driving Transformative Change Through Venture Creation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper contributes to venture‐creation research by examining how sustainable startups can overcome market constraints to drive transformative change through their business development. Conceptually, we address this question by identifying venture‐creation narratives in the learning and experimental phases of sustainable startups that ...

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Successional development of the phototrophic community in biological soil crusts, along with soil formation on Holocene deposits at the Baltic Sea coast

open access: yesFrontiers in Ecology and Evolution
Harsh environmental conditions form habitats colonized by specialized primary microbial colonizers, e.g., biological soil crusts (biocrusts). These cryptogamic communities are well studied in drylands but much less in temperate coastal dunes, where they ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Long term behaviour of singularly perturbed parabolic degenerated equation [PDF]

open access: yes, 2011
In this paper we consider models for short-term, mean-term and long-term morphodynamics of dunes and megariples. We give an existence and uniqueness result for long term dynamics of dunes.

Gender Mainstreaming in Urban Food Policies: Governance Processes and Policy Designs From Three Spanish Cities

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This paper explores the integration of gender mainstreaming in urban food policies (UFPs) through three Spanish case studies: Barcelona, Valencia, and Zaragoza. While UFPs are pivotal for addressing sustainability in urban food systems, attention to gender disparities within them remains insufficient.
