Differential cellular proliferation underlies heterochronic generation of cranial diversity in phyllostomid bats
Background Skull diversity in the neotropical leaf-nosed bats (Phyllostomidae) evolved through a heterochronic process called peramorphosis, with underlying causes varying by subfamily. The nectar-eating (subfamily Glossophaginae) and blood-eating (subfamily Desmondontinae) groups originate from insect-eating ancestors and generate their uniquely s...
Multi-faceted analysis provides little evidence for recurrent whole-genome duplications during hexapod evolution
Published in BMC Biology
BackgroundGene duplication events play an important role in the evolution and adaptation of organisms. Duplicated genes can arise through different mechanisms, including whole-genome duplications (WGDs). Recently, WGD was suggested to be an important driver of evolution, also in hexapod animals.ResultsHere, we analyzed 20 high-quality hexapod genom...
Sequencing and Analyzing the Transcriptomes of a Thousand Species Across the Tree of Life for Green Plants
The 1,000 Plants (1KP) initiative was the first large-scale effort to collect next-generation sequencing (NGS) data across a phylogenetically representative sampling of species for a major clade of life, in this case theViridiplantae, or green plants. As an international multidisciplinary consortium, we focused on plant evolution and its practical ...
On the origin of oxygenic photosynthesis and Cyanobacteria.
Published in The New phytologist
Oxygenic phototrophs have played a fundamental role in Earth's history by enabling the rise of atmospheric oxygen (O2 ) and paving the way for animal evolution. Understanding the origins of oxygenic photosynthesis and Cyanobacteria is key when piecing together the events around Earth's oxygenation. It is likely that photosynthesis evolved within ba...
A large-scale species level dated angiosperm phylogeny for evolutionary and ecological analyses
...
Phylogenies are a central and indispensable tool for evolutionary and ecological research. Even though most angiosperm families are well investigated from a phylogenetic point of view, there are far less possibilities to carry out large-scale meta-analyses at order level or higher. Here, we reconstructed a large-scale dated phylogeny including near...
Tackling Rapid Radiations With Targeted Sequencing
...Published in Frontiers in Plant Science
In phylogenetic studies across angiosperms, at various taxonomic levels, polytomies have persisted despite efforts to resolve them by increasing sampling of taxa and loci. The large amount of genomic data now available and statistical tools to analyze them provide unprecedented power for phylogenetic inference. Targeted sequencing has emerged as a ...
Signal evolution and morphological complexity in hummingbirds (Aves: Trochilidae)
Understanding how animal signals are produced is critical for understanding their evolution because complexity and modularity in the underlying morphology can affect evolutionary patterns. Hummingbird feathers show some of the brightest and most iridescent colors in nature. These are produced by optically complex stacks of hollow, platelet-shaped o...
Opportunities for short rotation coppice production on free-range chicken farms in Flanders : farmers' perceptions and c...
This paper focuses on systems producing short rotation coppice willows (SRCW) in chickens' free-range areas. We aim to map chicken farmers' motivation to implement SRCW, and to assess the economic viability of these systems. Semi-structured interviews were conducted with 18 free-range chicken farmers. Farmers agreed that chickens would prefer SRCW ...
Unconventional monetary policy and bank risk taking
We analyze the presence of bank risk taking associated with unconventional monetary policy in the United States between 2008 and 2015 using corporate syndicated loan data at the bank-firm level. We measure monetary policy using the identification-through-heteroskedasticity approach with a VAR model. To identify the risk-taking channel we control fo...
