Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

open access: yesEcological Entomology, EarlyView.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

open access: yesEcological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

PERIPHERY TO CENTRE STAGE: THE SARRASANI CIRCUS IN WEIMAR GERMANY

open access: yesGerman Life and Letters, EarlyView.
ABSTRACT The modern European circus was more than just entertainment: it was a powerful platform where fantasies of empire, ideas of national identity, and notions of racial difference came together and were put on public display. In interwar Germany, the Sarrasani Circus — the largest circus enterprise in the country at the time — built on the legacy ...

Cowbirds use conspecific social information to detect host nests in the wild

open access: yesIbis, EarlyView.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

open access: yesIbis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Long‐term population changes for the UK stag beetle Lucanus cervus—Evidence from citizen science surveys and museum collections

open access: yesInsect Conservation and Diversity, EarlyView.
The stag beetle Lucanus cervus is a European Protected Species and declining dead wood specialist, but long‐term population trends in the United Kingdom remain largely unknown. We used 82,883 citizen science records and historic data from museum records to compare geographic distribution trends, and results suggest a broadly stable distribution over ...
