Abstract:
Biological invasions are a major threat to biological diversity, agriculture, and human health. To predict and prevent new invasions, it is crucial to develop a better understanding of the drivers of the invasion process. The analysis of 4,533 border interception events revealed that at least 51 different alien ant species were intercepted at US ports over a period of 70 years (1914–1984), and 45 alien species were intercepted entering New Zealand over a period of 68 years (1955–2013). Most of the interceptions did not originate from species’ native ranges but instead came from invaded areas.

Identifying the origins of established alien species is important to prevent new introductions in the future. The greenhouse frog (Eleutherodactylus planirostris), native to Cuba, the Bahamas, and the Cayman Islands, has been widely introduced to the Caribbean, North and Central America, Oceania and Asia. This invasive alien amphibian was recently reported in Shenzhen, China, but the potential introduction sources remain poorly understood. Based on phylogenetic analysis using mitochondrial 16S, COI and CYTB sequences, we detected a complex introduction origin of this species, which may be from

Abstract:
The synthesis and single-crystal X-ray structure determination of a new cage molecule containing four oxygen, two sulfur, and two nitrogen heteroatoms are described. The structure determination shows that a twist occurs about each (tribenzyl) nitrogen bridgehead so that an overall helical configuration within putative quasi-2 symmetry is generated; both nitrogens have their lone pairs orientatedexo. Single crystals of this compound are homochiral. Semiempirical MO calculations have been used to probe the topological rigidity of this system relative to the more symmetrical analogue incorporatin

Abstract:
In the summer of 2021 we identified three new distribution localities of Darevskia praticola north of the Mureș River, and one locality south of the river. The habitats populated by D. praticola (broad-leaved forest with wet areas) and the altitude (175–245 m) of the new records are typical for this species. Nevertheless, D. praticola had not been recorded in 12 other localities with similar conditions from an area previously considered suitable for this species. Thus, D. praticola may be slowly expanding from a bridgehead north of the Mureș River, occupying new favorable habitats. Probably, D

Abstract:
The spectroscopic behavior of octa-t-butyltetra-2,3-triptycenotetraazaporphyrin and some of its metal complexes ( Cu 2+, Zn 2+ and Co 2+) were examined. UV-visible and electron paramagnetic resonance spectroscopy indicate that these phthalocyanine derivatives form cofacial dimers in pentane solution. Modeling suggests that the lowest energy configuration of the dimer is a self-complementary embrace in which the two phthalocyanine cores are staggered at an angle of 45° relative to each other. This configuration results in a remarkably intense and sharp absorption band (~635 nm; ε = ~4.0 × 105 M

Abstract:
Introduction. Hydraulic calculation of bridges is one of the most important stages in determining its basic geometric parameters. Therefore, it should be based on the exact equations of hydraulics that characterize the behavior of water flow. Currently, the hydraulic calculation of a small bridge is based on an empirically established dependence, which is that the compressed depth under the bridge hc is associated with the support H approximate dependence hc ≈ 0,5H and is independent of the compression of the flow bridge crossing. In this work, it is theoretically proved that taking such a rel

Abstract:
Global plant trade represents one of the main pathways of introduction for invertebrates, including insects, throughout the world. Non-native insects include some of the most important pests affecting cultivated and ornamental plants worldwide. Defining the origins and updating the distribution of non-native invasive species is pivotal to develop effective strategies to limit their spread. The agave weevil, Scyphophorus acupunctatus (Coleoptera, Dryophthoridae), is a curculionid beetle native to Central and North America, although it also occurs in Eurasia, Africa, Oceania and South America as

Abstract:
Les invasions biologiques constituent aujourd'hui une source d'inquiétude du fait de leur nette augmentation et des conséquences écologiques, économiques et sanitaires dont elles sont à l'origine. Pour qu'une population devienne envahissante, il faut (i) qu'elle soit introduite, (ii) qu'elle s'établisse et (iii) qu'elle prolifère. Chacune de ces trois étapes constitue un défi difficile à relever, et les processus en jeu sont encore mal connus.

This abstract is not so much a summary of the big stones laid thus far, but rather some point-work in the cementing that holds them all together. It is one of the longest of the chapter abstracts, for this, the shortest of the chapters. A summary is given of what the Constructive Logicist has been able to attain by means of core reasoning in accordance with natural-deduction rules of introduction and elimination, especially for carefully de signed abstraction operators. The naturals and the rationals are fully within Kroneckerian purview. But now one must prepare to engage with the reals. The
