Species-habitat networks reveal conservation implications that other community analyses do not detect. [PDF]

open access: yesEcol Appl
Abstract Grassland restoration is an important conservation intervention supporting declining insect pollinators in threatened calcareous grassland landscapes. While the success of restoration is often quantified using simple measures of diversity or similarity to target communities, these measures do not capture all fundamental aspects of community ...

Polling the Public to Select Flagship Species for Tourism and Conservation-A 'Big Five' for the Peruvian Amazon? [PDF]

open access: yesEcol Evol
Flagship species are used to promote conservation and tourism, but selecting species purely for prescribed appealing characteristics may overlook unique flagships or homogenise selections. A strategy of polling the public can more directly identify existing preferences for species for marketing.

Multi-method approach to assessing the floral-visiting insect assemblage of rare, abophilous plant Baccharis vanessae in Southern California. [PDF]

open access: yesEcol Evol
In this study, we compare the accuracy of two different methods of monitoring to assess the insect assemblage of Encinitas Baccharis (Baccharis vanessae): focal observations and video recordings from camera traps. The insect vectors identified were as expected given B. vanessae pollination syndrome.

Local and landscape scale woodland cover and diversification of agroecological practices shape butterfly communities in tropical smallholder landscapes

open access: yesJournal of Applied Ecology, Volume 60, Issue 8, Page 1659-1672, August 2023., 2023
We show that diversified agroecological soil practices and flowering plant richness enhanced butterfly abundance on farms. However, our results suggest that on‐farm measures cannot compensate for the negative effects of continued woodland conversion. Therefore, we call for more active protection of remaining African woodlands in tandem with promoting ...

Synchronous long‐term trends in abundance and compositional variability of butterflies in Central Europe

open access: yesEcosphere, Volume 14, Issue 7, July 2023., 2023
Abstract Annual insect abundances are determined by short‐term population fluctuations and long‐term trends in community composition. Any assessment of this temporal variability needs long‐term quantitative data on abundances. Here we use museum data (1940–2017) of butterflies and burnet moths from southwestern Germany and central Austria comprising ...

Nest survival of threatened Eurasian Curlew (Numenius arquata) breeding at low densities across a human‐modified landscape

open access: yesIbis, Volume 165, Issue 3, Page 753-766, July 2023., 2023
Targeted management actions to boost key demographic rates can help to restore rare and localized populations but are increasingly required to stabilize or reverse declines of formerly common and widespread species. Many breeding wader populations across Europe are declining because of unsustainably low rates of productivity, and the conservation tools

European Habitats Directive has fostered monitoring but not prevented species declines

open access: yesConservation Letters, Volume 16, Issue 3, May/June 2023., 2023
Abstract Strong biodiversity declines have been reported across the European Union, especially in insects, despite conservation policy such as the Habitats Directive that aims to halt biodiversity loss. Using 50 years of observational data, we examined indicators for the goals of the Directive in terms of improving monitoring efforts and occupancy ...

Tens of thousands of migrating hoverflies found dead on a strandline in the South of France Des dizaines de milliers de syrphes migrateurs retrouvés morts sur une plage du sud de la France

open access: yesInsect Conservation and Diversity, Volume 16, Issue 2, Page 306-312, March 2023., 2023
A high number of insects were found dead on a beach in the South of France. We suspect strong winds or a localised storm were at the origin of their stranding. All dead species recorded are known for their migratory behaviour and hoverflies made up about 77% of the dead insects.

High‐, medium‐, and low‐dispersal animal taxa communities in fragmented urban grasslands

open access: yesEcosphere, Volume 14, Issue 2, February 2023., 2023
Abstract Urbanized areas are rapidly expanding into a variety of habitats. Urbanization and suburbanization are often associated with changes in biodiversity, which are naturally influenced by biotic interactions and abiotic habitat characteristics. The main cause of changes caused by suburbanization is fragmentation.

Using Red List Indices to monitor extinction risk at national scales

open access: yesConservation Science and Practice, Volume 5, Issue 1, January 2023., 2023
The Red List Index (RLI) measures change in the aggregate extinction risk of species. It is a key indicator for tracking progress toward nine of the Aichi and many proposed post‐2020 Global Biodiversity Framework Targets. Here, we compare and promote two formulations of the RLI used for reporting biodiversity trends at national scales. Abstract The Red
