The structure of natural microbial enemy-victim networks

The persistence of generalists and specialists is a topical question in community ecology and results from both ecological and evolutionary processes. At fine taxonomical scales, ecological specialisation, i.e...

Indigenous marine resource management on the Northwest Coast of North America

There is increasing recognition among anthropologists that indigenous peoples of the Northwest Coast actively managed their terrestrial and marine resources and ecosystems. Such management practices ensured th...

Wind farm potential is higher in prime habitat for uncommon soil crust lichens

Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidin...

Ammonia-oxidizing archaea and bacteria are structured by geography in biological soil crusts across North American arid lands

Biological soil crusts (BSCs) can dominate surface cover in dry lands worldwide, playing an integral role in arid land biogeochemistry, particularly in N fertilization through fixation and cycling. Nitrificati...

Ecological characterization of soil-inhabiting and hypolithic soil crusts within the Knersvlakte, South Africa

Within the Knersvlakte, cyanobacteria occur hypolithically underneath translucent quartz stones in areas with quartz pavement and, outside pavement areas, they are soil-inhabiting within the uppermost millimet...

On the role of traditional ecological knowledge as a collaborative concept: a philosophical study

The concept of traditional ecological knowledge (TEK), along with synonymous or closely related terms like indigenous knowledge and native science, has some of its origins in literatures on international devel...

Lichen species dominance and the resulting photosynthetic behavior of Sonoran Desert soil crust types (Baja California, Mexico)

Lichen dominated biological soil crusts (BSCs) occur over large areas in the Sonoran Desert of the southwestern USA and northwest Mexico. In Baja California BSCs show a distinct patchiness and several types ca...

Long-term changes in biological soil crust cover and composition

Communities change over time due to disturbances, variations in climate, and species invasions. Biological soil crust communities are important because they contribute to erosion control and nutrient cycling. ...

Cultural and health implications of fish advisories in a Native American community

Fish advisories are issued in an effort to protect human health from exposure to contaminants, but Native American communities may suffer unintended health, social, and cultural consequences as a result of war...

Fluxes of water, sediments, and biogeochemical compounds in salt marshes

Tidal oscillations systematically flood salt marshes, transporting water, sediments, organic matter, and biogeochemical elements such as silica. Here we present a review of recent studies on these fluxes and t...

Regional-scale relationship among biological soil crusts, invasive annual grasses, and disturbance

Sagebrush ecosystems in western North America are being replaced by the invasion of annual grasses, particularly Bromus tectorum. In experimental situations and in localized landscapes, prior studies have documen...

Early life on land and the first terrestrial ecosystems

Terrestrial ecosystems have been largely regarded as plant-dominated land surfaces, with the earliest records appearing in the early Phanerozoic (<550 Ma). Yet the presence of biological components in pre-Phan...

Terrestrial denitrification: challenges and opportunities

Denitrification is a process of great environmental importance but is difficult to study in terrestrial ecosystems. Methods for quantifying the process are problematic, variability in activity is high, and tem...

A spatially distributed, deterministic approach to modeling Typha domingensis (cattail) in an Everglades wetland

The emergent wetland species Typha domingensis (cattail) is a native Florida Everglades monocotyledonous macrophyte. It has become invasive due to anthropogenic disturbances and is out-competing other vegetation ...

Shorebird patches as fingerprints of fractal coastline fluctuations due to climate change

The Florida coast is one of the most species-rich ecosystems in the world. This paper focuses on the sensitivity of the habitat of threatened and endangered shorebirds to sea level rise induced by climate chan...

Impacts of fire and phosphorus on sawgrass and cattails in an altered landscape of the Florida Everglades

Although fire as a critical ecological process shapes the Florida Everglades landscape, researchers lack landscape-based approach for fire management. The interactive effect of fire, nutrients, water depth, an...

Stable isotope enrichment in muscle, liver, and whole fish tissues of brown-marbled groupers (Epinephelus fuscoguttatus)

The purpose of this study was to assess enrichments in stable carbon and nitrogen isotopes (δ¹³C and δ¹⁵N) in brown-marbled groupers (Epinephelus fuscoguttatus), a marine fish that has been widely used in aquacul...

C:N:P stoichiometry and nutrient limitation of the soil microbial biomass in a grazed grassland site under experimental P limitation or excess

The availability of essential nutrients, such as nitrogen (N) and phosphorus (P), can feedback on soil carbon (C) and the soil microbial biomass. Natural cycles can be supplemented by agricultural fertiliser a...

Bacterial microcosms obey Taylor's law: effects of abiotic and biotic stress and genetics on mean and variance of population density

According to the empirical regularity called Taylor's law, the variance of population density in samples of populations is a power of the mean population density. The exponent is often between 1 and 2. Our exp...

Landscape features and weather influence nest survival of a ground-nesting bird of conservation concern, the greater sage-grouse, in human-altered environments

Ground-nesting birds experience high levels of nest predation. However, birds can make selection decisions related to nest site location and characteristics that may result in physical, visual, and olfactory i...

Refining spatial neighbourhoods to capture terrain effects

Spatially explicit ecological research has increased substantially in the past 20 years. Most spatial approaches require the definition of a spatial neighbourhood or the region over which spatial relationships...

Downscaling future climate scenarios to fine scales for hydrologic and ecological modeling and analysis

Evaluating the environmental impacts of climate change on water resources and biological components of the landscape is an integral part of hydrologic and ecological investigations, and the resultant land and ...
