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

Ecol 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.

Diversity of Butterflies (Hexapoda: Lepidoptera: Rhopalocera) Around Campus 4 of Universitas Ahmad Dahlan

Jurnal Riset Biologi dan Aplikasinya, 2021
The conversion of land functions can result in a decrease of environmental quality, which can reduce the diversity of butterflies. This study aimed to determine the diversity level and to find the most abundant and less abundant butterfly species around ...

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

Journal 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

Ecosphere, 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

Ibis, 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

Butterfly diversity in an urban area illustrates the significance of green spaces in urban biodiversity conservation [PDF]

Arthropods, 2023
Rapid urbanisation and population growth are a threat to butterflies found in urban habitats. In this study, we look at the diversity and abundance of butterflies in a small urban green space, our college campus which is surrounded by urban sprawl in ...

European Habitats Directive has fostered monitoring but not prevented species declines

Conservation 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 ...
