Spatial and temporal signatures of fragility and threshold proximity in modelled semi-arid vegetation [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2010
Understanding the behaviour of complex environmental systems, particularly as critical thresholds are approached, is vitally important in many contexts. Among these are the moisture-limited vegetation systems in semi-arid (SA) regions of the World, which support approximately 36 per cent of the human population, maintain considerable biodiversity and ...

Parametrization of the increase of the aeolian erosion threshold wind friction velocity due to soil moisture for arid and semi-arid areas [PDF]

Annales Geophysicae, 1999
Abstract. Large-scale simulation of the soil-derived dust emission in semi-arid regions needs to account for the influence of the soil moisture on the wind erosion threshold. Soil water retention consists of molecular adsorption on the soil grain surface and capillary forces between the grain.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Aridity threshold of ecological restoration mitigated atmospheric drought via land‒atmosphere coupling in drylands

Communications Earth & Environment
Land‒atmosphere coupling intensifies the vulnerability of ecosystems in drylands. However, whether and how ecological restoration would modify the land‒atmosphere coupling across drylands remains unclear.

A major reorganization of Asian climate by the early Miocene [PDF]

Climate of the Past, 2008
The global climate system experienced a series of drastic changes during the Cenozoic. In Asia, these include the climate transformation from a zonal pattern to a <i>monsoon-dominated pattern</i>, the disappearance of typical subtropical ...

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

The dominant effect of atmospheric drought on carbon and water fluxes in Central Asia and the response of critical thresholds

Agricultural Water Management
In the context of global climate change, the severity and frequency of drought events are on the rise. Compound droughts, marked by both soil aridity and atmospheric dry conditions, exert significant effects on how terrestrial ecosystems operate.

Classifying avian drinking behaviour: ecological insights and implications in a changing world

Biological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
