Junction canal Grantham & Sleaford 1833 plan
The 1794, Sleaford Navigation canalised the River Slea to the River Witham linking to the seaport of Boston. From 1797, the Grantham Canal connecting to the River Trent, transported coal to Grantham. Between the two towns ran 14 miles of the worst road in England (Stamford Mercury 1843). This denied Grantham and the East Midlands access to Boston's seaport to London. The Ancaster stone quarries lacked water transport to the west. John Rofe & Sons, Birmingham planned in 1833 a junction canal. In order not to injure or annoy the residence of any landed proprietor, the canal take a circuitous route. From Grantham, it rises from 60 meter above sea level to 125 m then enters a 25 m deep tunnel 2 1/2 miles in length. This would have made it the second longest canal tunnel in England. Unbuilt, there was a further attempt to link Sleaford, Grantham and Newark-on-Trent with a canal in 1840, but rendered superfluous by the railways arriving in the 1850s. Elevation x 8.

Data and R codes from: Exploring the effect of 195 years-old locks on species movement: Landscape genetics of painted turtles in the Rideau Canal, Canada
<p>Aquatic systems have been extensively altered by human structures (e.g., construction of dams/canals) and these have major impacts on the connectivity of wildlife populations through the loss and isolation of suitable habitats. Habitat loss and isolation affect gene flow and influence the persistence of populations in time and space by restricting movements. Isolation can result in higher inbreeding, lower genetic diversity, and greater genetic structure, which may render populations more vulnerable to environmental changes, and thus to extinction. Given the ubiquity and the persistence of dams and canals in space and time, it is crucial to understand their effects on the population genetics of aquatic species. Here, we documented the genetic diversity and structure of painted turtle (<em>Chrysemys picta</em>) populations in the Rideau Canal, Ontario, Canada. More specifically, we used 13 microsatellites to evaluate the influence of locks on genetic variation in 822 painted turtles from 22 sites evenly distributed along the 202-km canal. Overall, we found low, but significant, genetic differentiation suggesting that some dispersal is occurring throughout the canal. In addition, we showed that locks contribute to the genetic differentiation observed in the system. Clustering analysis revealed two distinct genetic groups whose boundary is associated with a series of six locks. Our results illustrate how artificial waterways, such as canal systems, can influence population genetic structure. We highlight the importance of adopting management plans that can mitigate the impacts of human infrastructure and preserve gene flow across the landscape to maintain viable populations.</p>

Morphological integration, canalization, and plasticity in response to emergence time in Abutilon theophrasti
<p>The relationships between trait plasticity and canalization, and between phenotypic integration and plasticity, have been under debate, largely because direct evidence is still scarce for their associations, especially in response to environments. To investigate the relationships between canalization, integration and phenotypic plasticity in response to emergence time, we conducted a field experiment with an annual herbaceous species of <em>Abutilon theophrasti</em>, by subjecting plants to four treatments of emergence time (spring, late spring, summer and late summer), to measure a number of morphological traits and analyze correlations of plasticity with canalization and integration in these traits, at two stages of plant growth. Results showed plants with delayed emergence had higher phenotypic integration and more positive correlations between integration and plasticity, but less negative correlations between decreased canalization and plasticity, compared to those emerged in spring. Results suggested significant environmental changes that induce plastic responses, rather than environmental stress, can result in greater phenotypic integration in plants. Negative correlations between decreased canalization and plasticity occurred more frequently in plants emerging in spring and the least frequently in those emerging in summer, suggesting their relationship depends on specific environmental conditions and the degree of plasticity. Both increased phenotypic integration and decreased canalization might merely be the outcome of plastic responses, rather than mechanisms constraining or facilitating plasticity.</p>

Beyond the exponential horn: a bush-cricket with ear-canals which function as coupled resonators
<p>Bush-crickets have dual-input, tympanal ears located in the tibia of their forelegs. The sound will, first of all, reach the external sides of the tympana, before arriving to the internal sides through the bush-cricket ear-canal, the acoustic trachea (AT), with a phase lapse and pressure gain. It has been shown that for many bush-crickets, the AT has an exponential horn-shaped morphology and function, producing a significant pressure gain above a certain cut-off frequency. However, the underlying mechanism of different AT designs remains elusive. In this study, we demonstrate that the AT of the duetting bush-cricket <em>Pterodichopetala</em> <em>cieloi</em> function as coupled resonators, producing sound pressure gains at the sex-specific conspecific calling song frequency, and attenuating the remainder – a functioning mechanism significantly different than an exponential horn. Furthermore, it is demonstrated that despite the sexual dimorphism between the <em>P</em>. <em>cieloi</em> AT, both male and female AT have a similar biophysical mechanism. The analysis was carried out using an interdisciplinary approach, where micro-computed tomography was used for the morphological properties of the <em>P</em>. <em>cieloi</em> AT, and a finite-element analysis was applied on the precise tracheal geometry to further justify the experimental results and to go beyond experimental limitations.</p>

Data from: Associations between developmental stability, canalization and phenotypic plasticity in plants with temporally heterogeneous environmental experience
<p>We subjected eight plant species to a first round of alternating inundation and drought vs. constantly moderate water treatments and a second round of water conditions. Fluctuating asymmetry (FA), intra- and inter-individual variations (CV<sub>intra</sub> and CV<sub>inter</sub>), and plasticity in traits were measured and correlations between variables were calculated for each species. Early temporally heterogeneous experience decreased the leaf size of half of the species, but had complex effects on leaf fluctuating asymmetry (FA) and inter-individual variation (CV<sub>inter</sub>) in traits immediately or in late conditions, with little effects on intra-individual variation (CV<sub>intra</sub>). There were several positive correlations between FA and CV<sub>inter</sub>, while there were correlations between CV<sub>inter</sub> and plasticity in early treatments, but negative ones in late treatments.</p>

Data from: The first pre-Quaternary fossil record of the clade Mabuyidae with a comment on the enclosure of the Meckelian canal in skinks
We here describe the first Neogene record of the squamate clade Mabuyidae. Although this clade has a cosmopolitan distribution today, no pre-Quarternary fossil record of these reptiles has so far been documented. The material comes from the locality Solnechnodolsk (Russia) and is dated to the late Miocene (MN 13). Although it comprises only jaw elements, it constitutes the first evidence of the occurrence of fossil skinks around the area of the Black Sea. The material is identical to Heremites vittatus, showing the existence of this lineage as early as the late Miocene. Thus, it may be used as a potential calibration point for further studies. The comparative anatomy of the structures of lower jaw in selected scincomorph taxa with a special reference to Mabuya group is presented. The closure of the Meckelian canal is the condition at the basal node of the clade Sphenomorphidae + Eugongylidae + Egerniidae + Mabuyidea, whereas the closed canal in Acontias (Acontidae) evolved independently. However, Sphenomorphidae (Asymblepharus and Scincella) + Eugongylidae (Ablepharus) retain a large anterior opening of the Meckelian canal, whereas only a small opening characterizes the basal node of Egerniidae and Mabuyidae, except for H. vittatus and H. septemtaeniatus. The closure of the Meckelian canal in these two taxa is less well developed in comparison with other mabuyid skinks. Thus, a heterochronic pedomorphic process might have played a role in the evolution of these skinks. The Meckelian canal condition supports the monophyly of Heremites.
Relationship of dredged canals and wetland loss in Louisiana
<p>The direct effects of converting wetlands to open water by dredging can be magnified by indirect effects. For example, the dredged canal allows for recovery of mineral fluids 1000s of m belowground which may induce geological subsidence or faulting; dredged material deposited at the surface to form continuous levees may create hydrologic stressors on the wetland plants resulting in a conversion to open water habitat as a result of both soil waterlogging and drying, less organic matter and sediment accumulation, or greater erosion. We quantified indirect effects by demonstrating a robust dose-response relationship between coastal land loss and dredging canals in the Mississippi and Niger river deltas over 60 years. Importantly, the ratio of land loss to canal area increases with time – a legacy effect. We also found that flood protection levees on the main channel did not magnify the effect of dredging on wetland loss by inhibiting sediment flow into adjacent wetlands along its banks.</p>
