Supplementary material from "Experimental evidence of human recreational disturbance effects on bird-territory establishment"
<p><strong>Abstract</strong></p> <p>The worldwide increase in human outdoor activities raises concerns for wildlife. Human disturbances, even at low levels, are likely to impact species during sensitive periods of the annual cycle. However, experimental studies during the putative sensitive period of territory establishment of birds which not only investigate low disturbance levels, but which also exclude the effect of habitat modification (e.g. walking trails) are lacking. Here, we experimentally disturbed birds in forest plots by walking through twice a day during territory establishment. Later we compared the breeding bird community of experimentally disturbed plots with that of undisturbed control plots. We discovered that the number of territories (−15.0%) and species richness (−15.2%) in disturbed plots were substantially reduced compared with control plots. Species most affected included those sensitive to human presence (assessed by flight-initiation distances), open-cup nesters and above-ground foragers. Long-distance migrants, however, were unaffected due to their arrival after experimental disturbance took place. These findings highlight how territory establishment is a sensitive period for birds, when even low levels of human recreation may be perceived as threatening, and alter settlement decisions. This can have important implications for the conservation of species, which might go unnoticed when focusing only on already established birds.</p>

Data from: North Asian Pliocene-Pleistocene beremendiin shrews (Mammalia, Lipotyphla, Soricidae): a description of material from Russia (Siberia), Kazakhstan, and Mongolia and the paleobiology of Beremendia
Beremendiini is an extinct group of soricine shrews that were widely distributed during the Pliocene and Pleistocene. Their occurrence in China has been investigated, but their presence in North Asian regions has remained poorly studied. This paper analyzes 56 fossil remains of Beremendiini collected from 16 early Pliocene to Early Pleistocene localities in Russia (Siberia), Kazakhstan, and Mongolia and shows the presence of two beremendiin species: Beremendia fissidens and Beremendia minor. North Asian Beremendia considerably varies in size and qualitative characteristics, although most of the different states have been identified in European or Chinese specimens. Through the application of geometric morphometric techniques, mandibular shape analyses reveal similarities between the members of the beremendiin genera Peisorex, Beremendia, and Lunanosorex. Shape analyses and comparisons of mandibular characteristics reveal 'trophic' analogies between Beremendia and Blarina members and a new model of 'Mandible Swinging and Sliding' (MSS-model) accounting for the similarities in mandibular morphology with implications for the understanding of the diet of Beremendia.
Biomass material - undulating venus shell - supported nanoscale zero-valent iron for the adsorption of Pb2+ and Cd2+ ions in aqueous solution
<p>Nanoscale zero-valent iron (NZVI) has a high adsorption capacity for heavy metals, but easily forms aggregates. Herein, preprocessed undulating venus shell (UVS) is used as support material to prevent NZVI from reuniting. The SEM and TEM results show that UVS had a porous layered structure and NZVI particles were evenly distributed on the UVS surface. A large number of adsorption sites on the surface of UVS-NZVI are confirmed by IR and XRD. UVS-NZVI is utilized for adsorption of Pb<sup>2+</sup> and Cd<sup>2+</sup> at pH=6 in aqueous solution, and <a name="_Hlk35440679">the experimental maximum adsorption capacities are 29.91 mg·g<sup>-1</sup> and 38.99 </a>mg·g<sup>-1</sup>, respectively. Adsorption isotherm results indicate that the adsorption of ions by UVS-NZVI is more in line with the Langmuir model when Pb<sup>2+</sup> or Cd<sup>2+</sup> existed alone. For the mixed solution of Pb<sup>2+</sup> and Cd<sup>2+</sup>, only the adsorption of Pb<sup>2+</sup> by UVS-NZVI conforms to the Langmuir model. Kinetic studies demonstrate that the determination coefficients (R<sup>2</sup>) of the pseudo first-order kinetic model for UVS-NZVI adsorption of Cd<sup>2+</sup> and Pb<sup>2+</sup> are higher than those of the pseudo second-order kinetic model and Elovich kinetic model. Highly efficient performance for metal removal makes UVS-NZVI show potential application to heavy metal ion adsorption.</p>

Supplementary material for "Glucocorticoid levels are linked to lifetime reproductive success and survival of adult barn owls"
<p><strong>Abstract</strong></p> <p>Glucocorticoid hormones, such as corticosterone, are crucial in regulating daily life metabolism and energy expenditure, as well as promoting short-term physiological and behavioural responses to unpredictable environmental challenges. Therefore, glucocorticoids are considered to mediate trade-offs between survival and reproduction. Relatively little is known about how selection has shaped glucocorticoid levels. We used 15 years of capture–recapture and dead recovery data combined with 13 years of corticosterone and breeding success data taken on breeding barn owls (<em>Tyto alba</em>) to investigate such trade-offs. We found that survival was positively correlated with stress-induced corticosterone levels in both sexes, whereas annual and lifetime reproductive success (i.e. the sum of young successfully fledged during the entire reproductive career) was positively correlated with both baseline and stress induced corticosterone levels in females only. Our results suggest that, in the barn owl, the stress-induced corticosterone response is a good proxy for adult survival and lifetime reproductive success. However, selection pressure appears to act differently on corticosterone levels of males and females.</p>
