Shell shape and environmental data for five North American land snail species
<p>The morphological distinctness of land snail shells is almost certainly related to the unique environments in which they live. Even with the development of genetic and epigenetic tools for understanding factors contributing to phenotype, much research is focused on understanding environmental effects on land snail shell form. Most studies focus on single taxa, with review articles summarizing shared patterns and correlations of shell response to the environment. Herein we provide a dataset of shell shapes and environmental data for five species of partially sympatric North American land snail. Data are sourced from museum specimens, invaluable resources for biological and biodiversity information. We imaged, landmarked, georeferenced, and extracted environmental parameters for 3,701 land snail specimens representing five North American land snail species: <em>Anguispira alternata</em>, <em>Euglandina rosea</em>, <em>Haplotrema concavum</em>, <em>Mesodon thyroidus</em>, and <em>Mesomphix globosus</em>. These specimens represent most of the primary dry holdings for the five species at the Florida Museum of Natural History, Gainesville, Florida, USA. The landmark and environmental data are provided in formats (TPS and CSV respectively) compatible with modern methods of analyzing and interpreting geometric morphometric data.</p>
Micro-tomographic images of a flask-shaped microfossil specimen from the Lower Devonian of China
<p>Our samples were prepared using palynological technique to extract specimens from rocks. After hydrochloric-hydrofluoric (HCL-HF) acid maceration and water rinsing to neutralization, organic residues were sieved with nylon mesh (10 μm mesh openings) to remove small impurities. Specimens were examined under a binocular stereo microscope for further microfossil analyses. A total of 16 specimens with typically flask-shaped forms were obtained and then photographed with the Tescan MAIA3 scanning electron microscope. We picked one specimen to take X-ray micro-tomography by using the Zeiss Xradia 520 Versa tomographic microscope. Image data were processed by the VGStudioMax 3.0. This dataset includes the raw micro-tomography images.</p>
Stochastic dispersal shapes the spatial pattern of species richness in mountain landscapes
<p class="MsoNormal"><strong><span>Aim<a name="OLE_LINK3"></a>: </span></strong><span><span>Biogeographers have begun to address the problem of species distribution patterns in three-dimensional space. A key question is: What patterns of species richness would arise on the three-dimensional surface of a landscape under minimal biological assumptions? Recently, a theory called "Landscape Elevational Connectivity" (LEC) has been developed, which measures how topography and geomorphology drive biodiversity patterns. Here, we tested the predictive ability of LEC for spatial patterns of species richness for the first time.</span></span></p> <p class="MsoNormal"><span><strong><span>Location: </span></strong></span><span><span>The Tibetan Plateau.</span></span></p> <p class="MsoNormal"><span><strong><span>Methods:</span></strong></span><span><span> We </span><span>used the "stacked species distribution models" (S-SDMs) approach to</span></span><span><span> estimate the empirical spatial distribution pattern of bird species richness on the Tibetan Plateau based on online species occurrence data and expert maps, and we compared this estimated distribution with the predictions of LEC.</span></span></p> <p class="MsoNormal"><span><strong><span>Results: </span></strong></span><span><span>We found a high correlation between the LEC null model and observed bird species richness in the biodiversity hotspot on the southeast edge of the Tibetan Plateau (Spearman's correlation, <em>r</em><span>s</span> = 0.746, 95% CI: 0.744-0.748).

We conclude that it would be fruitful to reconsider the contribution of deterministic factors to the distribution pattern of species richness, especially in mountain landscapes, by applying LEC as a null model.</span></span></p>

Dolphin-shaped lavabo with a bowl
The presented object is a wall lavabo – for washing the hands of a priest before the liturgy. It consists of two elements: a water vessel and a bowl. The vessel is made of forged and repousse copper sheet; it has the shape of a dolphin bent in a sigmoidal shape in the conventional approach typical of modern art. The animal's surface is covered with scales rendered in the repousse technique, and the fins were cast in brass. Its open mouth surrounds the spout with a valve. On the dolphin's belly there is a handle used for hanging the vessel on the wall. The bowl has the shape of a palmette shell and features holes for attaching it to the wall.

Data from: Hydrodynamic performance of suction feeding is virtually unaffected by variation in the shape of the posterior region of the pharynx in fish
To capture prey by suction, fish generate a flow of water that enters the mouth, and exits at the back of the head. It was previously hypothesized prey-capture performance is improved by a streamlined shape of the posterior region of the pharynx, which enables an unobstructed outflow with minimal hydrodynamic resistance. However, this hypothesis remained untested for several decades. Using computational fluid dynamics simulations, we now managed to quantify the effects of different shapes of the posterior pharynx on the dynamics of suction feeding, based on a feeding act of a sunfish (Lepomis gibbosus). In contrast to what was hypothesized, the effects of the imposed variation in shape were negligible: flow velocity patterns remained essentially identical, and the effects on feeding dynamics were negligibly small. This remarkable hydrodynamic insensitivity implies that, in course of the evolution, the observed wedge-like protrusions of the pectoral surfaces of the pharynx probably resulted from spatial constraints and/or mechanical demands on the musculoskeletal linkages, rather than constraints imposed by hydrodynamics. Our study therefore exceptionally shows that a streamlined biological shape subjected to fluid flows is not always the result of selection for hydrodynamic improvement.
