Host plants and experimental warming impact fitness and infection outcomes in a migratory butterfly

Ecological Entomology, EarlyView.
Host plant species interacted with temperature treatment to shape monarch survival and infection probabilities. Temperature modified the expected role of tropical milkweed, which did not confer OE resistance to monarchs under elevated temperatures.

The occurrence of the Monarch butterfly, Danaus plexippus L. in the Azores, with a brief review of its biology. [PDF]

, 2001
The Monarch butterfly, Danaus plexippus L. (Lepidoptera, Nymphalidae), has been an occasional visitor to the Azores. However, during the last two decades it has become a resident species in these islands and has adapted its behaviour to the geographic ...

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, EarlyView.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

The conservatism of prairie pollinators according to experts and empiricism

Insect Conservation and Diversity, EarlyView.
We derived ecological conservatism values for prairie pollinators using expert opinion and analysis of remnant fidelity. Expert values were potentially biased and struggled to differentiate between remnant and non‐remnant prairie sites Empirical values showed advantages for pollinator‐based site assessment and prioritization in prairie regions ...

Native insect species should be selected for classroom rearings

Insect Conservation and Diversity, EarlyView.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Strategic mowing of roadside milkweeds increases monarch butterfly oviposition

Global Ecology and Conservation, 2019
The eastern North American migratory population of monarch butterflies (Danaus plexippus) has declined precipitously due, in part, to the widespread decline of its obligate host plant, milkweed (Asclepias spp.). Linear right-of-ways (e.g.

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,
