Towards red listing understudied tropical insects: A case study of the dung beetles of Sabah, Malaysian Borneo

open access: yesInsect Conservation and Diversity, EarlyView.
We performed an IUCN Red List assessment for 159 dung beetle species from Sabah, Malaysian Borneo. Due to the lack of population demographic data, only Criterion B (i.e. geographic range) could be applied. Our findings show that the IUCN Red List Criteria can be applied to insect species based solely on occurrence data but highlight the importance of ...

Higher gregarine parasitism often in sibling species of host damselflies with smaller geographical distributions [PDF]

open access: yes, 2012
1. This study investigated inter-specific variation in parasitism by gregarines (Eugregarinorida: Actinocephalidae), among sibling species of damselflies (Odonata: Zygoptera), in relation to relative size of geographical ranges of host species.

Water availability and land‐use shape the diversity of Odonata in the Middle East

open access: yesInsect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

High Abundances of Species in Protected Areas in Parts of their Geographic Distributions Colonized during a Recent Period of Climatic Change [PDF]

open access: yes, 2014
It is uncertain whether Protected Areas (PAs) will conserve high abundances of species as their distributions and abundances shift in response to climate change. We analyzed large datasets for 57 butterfly and 42 odonate species (including four that have

Biodiversity and its restoration in limestone quarries: a review

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Limestone quarries impact natural areas, and they are spreading in relation to human population growth. Little is known about the impact of limestone quarries and their restoration on biodiversity. Objectives This review aims to provide an overview of how biodiversity is assessed in limestone quarries, how it impacts biodiversity,
