Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Forces Behind South Australia's Unusual Structural Changes Since 1840

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
