Change in predicted lagomorph species richness from the 1930s to 2080s.

<p>(<b>a</b>) Global patterns in predicted species loss and gain showing details in (<b>b</b>) North America and (<b>c</b>) Asia. Light grey indicates areas occupied by “unmodellable” species with uncertain outcomes.</p

Relationships between species traits and responses to future climate change.

<p>The ability of species’ traits to predict changes in (<b>a</b>) range (<b>b</b>) mean elevation (<b>c</b>) maximum elevation and (<b>d</b>) (<b>e</b>) (<b>f</b>) poleward movement under future climate (between ∼1930s and ∼2080s) for each group; pikas (red), rabbits (blue) and hares and jackrabbits (black). Diet breadth is a categorical variable and is therefore represented as a bar plot (±1 standard error) with sample sizes (i.e. numbers of species) shown above the bars. Only significant predictors of change are shown here. The dashed line at zero indicates no change in the response variable.</p

Characterisation of predicted lagomorph bioclimatic envelope change.

<p>Scatterplots show the linear relationship between range change (%) and (<b>a</b>) poleward movement (°), (<b>b</b>) elevational change (m) and (<b>c</b>) poleward movement and elevational change. The numbers of species in each quadrant that exhibited positive or negative change on each axis are shown with percentages in parentheses. Temporal trends for (<b>d</b>) range change, (<b>e</b>) poleward movement and (<b>f</b>) elevational change ± 1 standard error for each species group; pikas (red), rabbits (blue) and hares and jackrabbits (black).</p

A simultaneous dual-site technosignature search using international LOFAR stations

The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence of technologically advanced extraterrestrial life. Radio signals similar to those engineered on Earth may be transmitted by other civilizations, motivating technosignature searches across the entire radio spectrum. In this endeavor, the low-frequency radio band has remained largely unexplored; with prior radio searches primarily above 1 GHz. In this survey at 110–190 MHz, observations of 1,631,198 targets from TESS and Gaia are reported. Observations took place simultaneously with two international stations (noninterferometric) of the Low Frequency Array in Ireland and Sweden. We can reject the presence of any Doppler drifting narrowband transmissions in the barycentric frame of reference, with equivalent isotropic radiated power of 1017 W, for 0.4 million (or 1.3 million) stellar systems at 110 (or 190) MHz. This work demonstrates the effectiveness of using multisite simultaneous observations for rejecting anthropogenic signals in the search for technosignatures</p
