Climate constrains the evolutionary history and biodiversity of crocodylians [PDF]
, 2015 The fossil record of crocodylians and their relatives (pseudosuchians) reveals a rich evolutionary history, prompting questions about causes of long-term decline to their present-day low biodiversity.

Preserving morphology while extracting DNA: a non-destructive field-to-museum protocol for slide-mounted specimens [PDF]
Biodiversity Data JournalOur study aimed to develop an optimised laboratory protocol ensuring the preservation of morphological structures and extraction of high-quality DNA sequences from Psychodidae (Insecta, Diptera) specimens. With 310 analysed specimens, we investigated the

Synchronised monitoring of plant and insect diversity: a case study using automated Malaise traps and DNA-based methods [PDF]
Biodiversity Data JournalThe occurrence and distribution of insects and their possible associations with plant species are largely unknown in Germany and baseline data to monitor future trends are urgently needed.

Per capita interactions and stress tolerance drive stress-induced changes in biodiversity effects on ecosystem functions [PDF]
, 2016 Environmental stress changes the relationship between biodiversity and ecosystem functions, but the underlying mechanisms are poorly understood. Because species interactions shape biodiversity-ecosystem functioning relationships, changes in per capita ...

Protosiphonorhinus patrickmuelleri gen. et sp. nov., the first fossil member of the sucking millipede family Siphonorhinidae (Colobognatha, Siphonophorida) described from Cretaceous Myanmar amber [PDF]
Evolutionary SystematicsMillipedes (Diplopoda) are an abundant group of fossilized terrestrial arthropods throughout the Palaeozoic Era. However, there is a gap in the Mesozoic Period with only slightly more than a dozen fossils known, until more recent fossil records – mainly ...

Island time and the interplay between ecology and evolution in species diversification. [PDF]
, 2015 Research on the dynamics of biodiversity has progressed tremendously over recent years, although in two separate directions - ecological, to determine change over space at a given time, and evolutionary, to understand change over time.
