iCE40 Bitstream Size Reduction - Bitstreams and Reconfiguration Time Measurements
<p>The HDF5 file contains data from an experiment concerning bitstream size reduction for Lattice iCE40 FPGAs.</p> <p>Five projects were synthesized with two different toolchains and afterwards compacted and compressed.

Metabolic rate in common shrews is unaffected by seasonal temperature, leading to reduction of energetic costs through size reduction
<p>Small endothermic mammals have high metabolisms, particularly at cold temperatures. In light of this, some species have evolved a seemingly illogical strategy: they reduce the size of the brain and several organs to become even smaller in winter. To test how this morphological strategy affects energy consumption across seasonally shifting ambient temperatures, we measured oxygen consumption and behaviour in the three seasonal phenotypes of the common shrew (<i>Sorex araneus</i>), which differ in size by about 20%. Body mass was the main driver of oxygen consumption, not the reduction of metabolically expensive brain mass. Against our expectations, we found no change in relative oxygen consumption with low ambient temperature. Thus, smaller body size in winter resulted in significant absolute energy savings. This could only partly be explained by a change in activity budgets. Our findings highlight that these shrews manage to avoid one of the most fundamental and intuitive rules of ecology allowing them to subsist with lower resource availability and successfully survive the harsh conditions of winter.</p>
Reductions in home-range size and social interactions among dehorned black rhinoceroses (Diceros bicornis)
<div> <p>Poaching for horns and tusks is driving declines of megaherbivores worldwide, including the critically endangered African black rhinoceros (<em>Diceros</em> <em>bicornis</em>). By proactively dehorning entire rhinoceros populations, conservationists aim to deter poaching and prevent species loss. However, such conservation interventions may have hidden and underestimated effects on animals' behavior and ecology. Here, we combine >15 y of black rhino–monitoring data across 10 South African game reserves, comprising >24,000 sightings of 368 individuals, to determine the consequences of dehorning for black rhino space use and social interactions. While preventative dehorning at these reserves coincided with a nationwide decrease in black rhino mortality from poaching and did not infer increased natural mortality, dehorned black rhinos decreased their home range area by, on average, 11.7 km<sup>2</sup> (45.5%) and were 37% less likely to engage in social encounters. We conclude that dehorning black rhinos as an antipoaching measure alters their behavioral ecology, although the potential population-level effects of these changes remain to be determined.</p> </div>
Data from: The costs of living on the coast: reduction in body size and size-specific reproductive output in coastal populations of a widespread amphibian
<ol> <li>Body size is a critical component of organismal biology. Body size is known to be influenced by a plethora of environmental conditions, among which exposure to large-scale variations of salinity has been comparatively overlooked. Yet, exposure to salinity is known to affect energetic allocation toward growth and reproduction.</li> <li>In this study, we investigated the morphological differences between inland and coastal individuals of spined toads (<em>Bufo</em> <em>spinosus</em>) in Western France. </li> <li>We measured adult morphology both outside and during the reproductive season on 190 individuals, and assessed reproduction in pairs originating from inland (N=20) and coastal (N=30) environments.</li> <li>Overall, we found that adult coastal toads were smaller and lighter than inland individuals. Reproductive correlates of these differences included lower fecundity and smaller egg size (but higher egg density) in coastal females. Interestingly, these differences were not allometric correlates of body size, as coastal females invested proportionally less in all components of reproduction (fecundity, egg size and egg protection).</li> <li>These results suggest altered resource allocation to growth and reproduction in coastal amphibians, which may be related to the marked spatial gradient of salinity (measured in reproductive ponds) and the associated costs of osmoregulation (higher osmolality in coastal individuals), for which local adaptation and higher tolerance to salinity remains to be tested.</li> </ol>

Data from: Reductions in body size of benthic macroinvertebrates as a precursor of the Early Toarcian (Early Jurassic) extinction event in the Lusitanian Basin, Portugal
Reduction of body size is a common response of organisms to environmental stress. Studying the Early Toarcian succession in the Lusitanian Basin of Portugal, we tested whether the shell size of benthic marine communities of bivalves and brachiopods changed at and prior to the global, warming-related Toarcian Oceanic Anoxic Event (T-OAE). Statistical analyses of shell size over time show that the mean shell size of communities decreased significantly prior to the T-OAE. This trend is distinct in brachiopods and is caused by larger-sized species becoming less abundant over time, whereas it is not significant in bivalves, suggesting a decoupled response to environmental stress. Reductions in shell size precede the decline in standardized sample-level species richness associated with the Early Toarcian extinction event. Such decreases in the shell size of marine invertebrates, well before the onset of biodiversity change, suggest that reductions in body size more generally may be a precursor of a subsequent loss of species and turnover at the community-level caused by climate change. Sedimentological evidence is against hypoxia as a driver of extinction and preceding size decrease in the brachiopod fauna in the studied succession, although low oxygen levels are widely held responsible for elevated Early Toarcian extinction rates globally. Reduction of mean shell size in brachiopods but stasis in bivalves is difficult to explain with ocean acidification because experimental work shows that brachiopods can be resilient to lowered pH, albeit long-term metabolic costs and potential evolutionary adaptations are unknown. Rising Early Toarcian temperatures in the Lusitanian Basin seem to be a plausible factor in both diversity decline associated with the T-OAE as well as the preceding reductions in mean shell size because thermal tolerances in modern bivalves are among the highest within marine invertebrates.
