Separation of analytic sets by rectangles of low complexity
, 2014 We provide Hurewicz tests for the separation of disjoint analytic sets by rectangles of the form $\Gamma\times\Gamma'$ for $\Gamma,\Gamma'\in {\mathbf\Sigma^0_1 , \mathbf\Pi^0_1 , \mathbf\Pi^0_2 }$

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts
Conservation Science and Practice, EarlyView.Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

Ibis, EarlyView.Biodiversity conservation requires effective monitoring of ecological communities in remote locations, where limited accessibility often restricts survey efforts. Passive acoustic monitoring (PAM) is becoming an established method for measuring biodiversity, facilitated by the increased accessibility of autonomous recording units.

On the Diameter of Universal Cover
, 2018 Here we obtain upper bounds for diameters of covering spaces of compact length spaces with the lifted metric. We give a proof by Sergei Ivanov of the fact that the diameter of an $n$-fold cover of a space of diameter $d$ is bounded above by $dn$. We also

Countable dense homogeneity in powers of zero-dimensional definable spaces [PDF]
, 2015 We show that, for a coanalytic subspace $X$ of $2^\omega$, the countable dense homogeneity of $X^\omega$ is equivalent to $X$ being Polish. This strengthens a result of Hru\v{s}\'ak and Zamora Avil\'es.
