Data from: Bite of the cats: relationships between functional integration and mechanical performance as revealed by mandible geometry
Cat-like carnivorous mammals represent a relatively homogeneous group of species whose morphology appears constrained by exclusive adaptations for meat eating. We present the most comprehensive dataset of extant and extinct cat-like species to test for evolutionary transformations in size, shape and mechanical performance, i.e. von Mises stress and surface traction, of the mandible. Size and shape were both quantified by means of Geometric Morphometrics while mechanical performance was assessed applying Finite Element Models to two dimensional geometry of the mandible. Additionally, we present the first almost complete composite phylogeny of cat-like carnivorans for which well-preserved fossil mandibles are known, including representatives of 35 extant and 59 extinct species of Felidae, Nimravidae and Barbourofelidae. This phylogeny was used to test morphological differentiation, allometry, and covariation of mandible parts within and among clades. After taking phylogeny into account, we found that both allometry and mechanical variables exhibit a significant impact on mandible shape. We also tested if mechanical performance was linked to morphological integration. Mechanical stress at the coronoid process is higher in sabertoothed cats than in any other clade. This is strongly related to the high degree of covariation within modules of sabertooths mandibles. We found significant correlation between integration at the clade level and per-clade averaged stress values, on both original data and by partialling out interclade allometry from shapes when calculating integration. This suggests a strong interaction between natural selection and the evolution of developmental and functional modules at the clade level.

An integrated single-cell RNA-seq atlas of the mouse hypothalamic paraventricular nucleus links transcriptional and function types
<p>The hypothalamic paraventricular nucleus (PVN) is a highly complex brain region that is crucial for homeostatic<br> regulation through neuroendocrine signalling, outflow of the autonomic nervous system (ANS), and projections<br> to other brain areas. The past years, single-cell datasets of the hypothalamus have contributed immensely<br> to the current understanding of the diverse hypothalamic cellular composition. While the PVN has been<br> adequately classified functionally, its molecular classification is currently still insufficient.</p> <p>To address this, we created a detailed atlas of PVN transcriptional cell types by integrating various PVN<br> single-cell datasets into a recently published hypothalamus single-cell transcriptome atlas. Furthermore, we<br> functionally profiled transcriptional cell types, based on relevant literature, existing retrograde tracing data<br> and existing single-cell data of a PVN-projection target region.</p>

Supplementary data to: Trapped in the morphospace: the trade-off between morphological integration and functional performance can limit adaptation
<p>The evolution of complex morphological structures can be seen as the result of interplay between different anatomical units evolving in a coordinated fashion. These can be influenced by genetic, developmental and/or functional integration in response to selective pressures. Using the highly derived humeral morphology of talpid moles as model, here we test whether functional specialization (measured as performance) can be linked to increased levels of morphological integration and, if so, what is the extent of the relationship. Combining 2D geometric morphometrics, phylogenetic comparative methods and functional landscape modelling, we demonstrate that the high biomechanical performance of subterranean moles was coupled with a high degree of integration, whereas less specialized taxa displayed intermediate or low magnitudes of integration. Theoretical morphs occurring in high-performance areas of the functional landscape not covered by any species showed a marked drop in covariation levels, suggesting the existence of a genuine tradeoff between integration and performance in the evolution of talpid moles. We argue that the remarkable stability of the subterranean environment may have helped constraining humeral morphology over a restricted area of the functional landscape, trapping subterranean moles in a narrow region of the landscape, impeding any attempt to reposition on a new ascending slope.</p>

Figure 2 It shows how DRYvER will use this cyclic model as a structured loop embedded in a meta-system perspective to guide adaptive management of DRNs. DRYvER will translate climate projections into changes in flow intermittence patterns at multiple scales, including that of the strategically-selected focal DRNs. This physical setting will then be used to implement a dynamic meta-system perspective to understand the cascading changes in biodiversity, ecosystem functions and ecosystem services. This knowledge will be integrated to develop a multi-criteria decision framework combining scientific, management, socio-economic, legislative barriers and leverages to promote an adaptive management of DRNs.

Functional integration of multiple sexual ornaments: signal coherence and sexual selection
<p><span>The sexual ornamentation of animals typically consists of multiple distinct traits. The classical research approach focuses on differences among these traits, but this approach may often be misleading because of correlations among distinct sexual traits of similar origins. There are many published studies on the correlation structures of sexual traits, but the way receivers take into account the components of an integrated, multi-component trait system remains mostly unknown. Here we propose a general analytical framework to assess the possible sexual selection consequences of within-individual coherence in the expression of multiple correlated sexual traits. We then apply this framework to a long-term mutual plumage coloration data set from a wild bird population. The results suggest that the coherence of component plumage color traits is not sexually selected. However, component trait coherence affects sexual selection on integrated plumage color. When assessing across-spectrum plumage reflectance, receivers choosing mates apparently disregard a component trait if it is inconsistent with the overall expression of other components. This indicates that separately examining and manipulating distinct sexual traits may often be misleading. Theoretical and empirical studies should further explore the effects of coherence on the ornament-preference</span><span> co-evolution.</span></p>
