Spring Season Survey of the Urban Blowflies (Diptera: Calliphoridae) of Chicago, Illinois [PDF]

open access: yes, 2017
During May 1980, 1165 blowflies of 12 species were trapped on chemically enhanced rat carrion baits in a dense urban setting in Chicago. In descending order, Cynomyopsis cadaverina, Lucilia sericata, and Phormia regina were the most abundant species ...

Spring Phenological Records at Edmonton, Alberta

open access: yesThe Canadian field-naturalist, 1960
Flowering dates of several species at Edmonton, Alberta, are presented for the period 1926-1958. These dates are correlated with temperature records, the heat accumulated for flowering being expressed in thermal units (degree-days).

Long‐term monitoring reveals biomass loss and concurrent dominance changes in coastal zooplankton community

open access: yesEcography, EarlyView.
Anthropogenically induced changes in environmental conditions have been affecting species communities globally, leading to shifts in ecosystem functioning. Physical drivers like temperature, salinity and acidification are especially important in coastal ecosystems, and high‐resolution time‐series are essential to identify how these variables affect ...

Timing avian long-distance migration: from internal clock mechanisms to global flights [PDF]

open access: yes, 2017
Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away.

Data integration advances reproductive phenology research across temporal, spatial and taxonomic scales

open access: yesEcography, EarlyView.
Climate change is altering plant reproductive phenology; however, a scarcity of long‐term, systematic monitoring hinders our ability to quantify and predict these responses in many parts of the world. We addressed this gap by demonstrating how data integration can be used to produce a synthesised record of reproductive phenology observations (flowering

The Aphids (Homoptera: Aphididae) Associated With Bell Peppers and Surrounding Vegetation in Southern Illinois [PDF]

open access: yes, 2018
Outbreaks of cucumber mosaic virus (CMV) disease, caused by an aphid- transmitted pathogen, greatly reduced yields of bell pepper in southern Illinois in the mid-1990s.

Anuran call properties as reliable indicators of environmental suitability for reproduction

open access: yesFrontiers in Ecology and the Environment, EarlyView.
The onset of animal breeding activity is often accompanied by auditory signals, typically produced by males, that indicate reproductive status to potential mates and competitors. Here, using male anuran advertisement calls as a case study, we present the novel hypothesis that characteristics of ectotherm auditory signals that are modulated by ...

Linkages between climate, seasonal wood formation and mycorrhizal mushroom yields [PDF]

open access: yes, 2016
Fungi provide important forest ecosystem services worldwide. In Mediterranean pine forests, predicted warmer and drier conditions could lead to a decline in mushroom yields.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.
