Ascomycetes From North Temperate Lakes in Wisconsin
A comprehensive study of freshwater ascomycetes in seven lakes in northern Wisconsin was carried out. These lakes are part of the Long Term Ecological Research (LTER) project and have been the subject of limnological studies since the early 1900's. Our knowledge of freshwater ascomycetes is fairly …

Tropicalisation of temperate seagrass meadows in Western Australia: Predicting the impact of tropical herbivorous fishes on temperate seagrass meadows
… in the distribution of tropical species to temperate regions, a process termed “tropicalisation”. The poleward expansion of tropical herbivores into temperate seagrass meadows is predicted to increase grazing pressure and alter ecosystem services and processes in these seagrass systems. This …

Trophic Dynamic Interactions in a Temperate Karst River
<p>Surface streams in karst landscapes are often characterized by high nutrient levels due to incomplete filtration through series of innumerable, below-ground conduits. Seasonal growth of the filamentous alga, Cladophora, is typically associated with nutrient-rich waters. This research compared …

Concrete ecological enhancement in the temperate marine environment
… were monitored between April and October in a temperate harbour. Using video footage, it was possible to ascertain the length of time bass, shore crabs, and shanny spent in each habitat and what behaviours they engaged in. More time was generally spent sheltering within the seaweed-covered …

Hair Sheep Production in Temperate, Deciduous Appalachian Silvopastures
… have been proposed for silvopastures in humid temperate regions, but little data comparing animal performance from systems with different deciduous tree species are available. Forage and animal performance was compared from open systems (i.e., no trees) with that from silvopastures containing …

Effects of anthropogenic land use on temperate mangrove forests
… effects of human land use on several aspects of temperate mangrove ecosystems and aims to identify potential vulnerabilities of ecosystem processes to provide a holistic view on the impacts that humas are having on these important ecosystems. By working across a broad gradient of human land use, …

Dynamics and Drivers: Carbon fluxes from temperate freshwater reservoirs
… the highest recorded in the literature from temperate reservoir systems (means up to 48 mg m-2 day-1), while CO2 rates of influx were among the highest (means up to 687 mg m-2 day-1). However, these flux rates were heterogeneous between reservoirs and within reservoirs, dependent upon the …

Diversification dynamics and evolution of the Australian temperate flora
The Australian temperate flora mostly comprises sclerophyllous elements that are a dominant and characteristic feature of the southern half of the Australian continent. Despite being a characteristic component of the Australian biota, the diversification dynamics and evolutionary history of this …

Frontiers in alley cropping: Transformative solutions for temperate agriculture
… the economic competitiveness of the most common temperate AC system – black walnut trees for timber with annual grain alley crops – against the widespread maize-soybean rotation. Even without monetization of environmental benefits, I demonstrate that AC can improve landowner profitability across …

Towards an understanding of seasonal ecophysiology in north-temperate fish
… a process putatively present in 20 other north-temperate fish species. Then, I conducted biweekly field sampling across five pumpkinseed populations to investigate how seasonal patterning in foraging, structural modifications, and energy accumulation across multiple somatic tissues shape …

A Global Conservation Assessment of Temperate Forests: Status and Protection
… of forests in three major biomes; boreal, temperate and tropical. I found that forests in the temperate biome are less abundant and less protected than forests in the boreal and tropical biomes. I conducted regional analyses for five continents on the degree of protection of temperate …

Does nest size constrain clutch size? A tropical-temperate test
… clutch size of tropical as opposed to north temperate birds has intrigued researchers for a long time. An untested hypothesis posits that higher nest predation in the tropics favors smaller nests thereby constraining clutch-size. We tested this hypothesis by conducting an experiment to test …

Microbial diversity and activity in temperate forest and grassland ecosystems
Ecosystems currently face widespread biodiversity losses and other environmental disturbances, such as climate warming, related to increased anthropogenic activities. Within this context, scientists consider the effects of such changes on the biodiversity, and hence on the activity, of soil …

Emission of biogenic halocarbons in temperate and tropical coastal zones
… incubations of 15 species. Laboratory studies on temperate macroalgae were also performed, with a focus on the impact of exposure and desiccation on halocarbon emissions. Desiccation-related halocarbon emissions are of interest due to a growing seaweed aquaculture industry; seaweeds are often left …
