Persistence and dynamic of forest snails in the Western Carpathians over the last 40 thousand years
Boreas, EarlyView.The glacial/interglacial cycles have shaped the landscape of temperate Europe for the past 2.5 million years, with open landscapes prevailing during the glacial and forested landscapes during the interglacial periods. However, the survival and recolonization strategies of temperate forest species during glacial phases remain poorly understood and hotly

European Journal of CombinatoricsGiven a metric space $\mathcal{M}$ that contains at least two points, the chromatic number $χ\left(\mathbb{R}^n_{\infty}, \mathcal{M} \right)$ is defined as the minimum number of colours needed to colour all points of an $n$-dimensional space $\mathbb{R}^n_{\infty}$ with the max-norm such that no isometric copy of $\mathcal{M}$ is monochromatic.

Boreas, EarlyView.The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Lessons from an eradication under multiple constraints of an island rat population of record density
Conservation Biology, EarlyView.Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Partition regularity of Pythagorean pairs
Forum of Mathematics, PiWe address a core partition regularity problem in Ramsey theory by proving that every finite coloring of the positive integers contains monochromatic Pythagorean pairs (i.e., $x,y\in {\mathbb N}$ such that $x^2\pm y^2=z^2$ for some $z ...

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages
The Economic History Review, EarlyView.Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

European Journal of Philosophy, EarlyView.ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...
