Curio muirii is the only species in the genus with bifacial leaves, making it crucial for understanding leaf evolution in this group. Leaf development can be divided into three stages: initiation, bizonal primordium, and intercalary growth. The developing leaves of C. muirii are bifacial and resemble those of other angiosperms from inception to the end of the bizonal primordium stage. However, as in monocots, the primary vascular bundles differentiate at the end of the bizonal primordium stage. The unifacial forerunner tip, which is recognized for Curio species but unknown for other eudicots, is the rst discernible part of the de nitive leaf. The leaf blade and petiole in C. muirii are distinctive in their biphasic development during the intercalary stage. The petiole grows faster than the leaf blade during the rst phase. During the second phase, the lamina overcomes the petiole in terms of length. In the developing leaf blade, the marginal meristem was not found. Adaxial meristem activity causes the leaf base to thicken unevenly during intercalary growth and envelopes the younger leaf primordium in the resultant depression.
Curio muirii是该属中唯一具有双面叶的物种,因此对于了解该类植物的叶片进化至关重要。叶片的发育可分为三个阶段:起始阶段、双叶初生阶段和闰叶生长阶段。C. muirii 发育中的叶片是双面的,从起始阶段到双层原基阶段的末期与其他被子植物的叶片相似。然而,与单子叶植物一样,初级维管束在双叶初生期末期分化。单面先端是原始叶片的第一个可辨认部分,库里欧属植物有单面先端,而其他真叶植物则没有。C. muirii 的叶片和叶柄在闰叶阶段具有独特的双相发育特征。在第一阶段,叶柄的生长速度快于叶片。在第二阶段,叶片的长度超过叶柄。在发育中的叶片中,没有发现边缘分生组织。正面分生组织的活动会导致叶基部在闰生期间不均匀地变厚,并将幼叶初生体包裹在由此产生的凹陷中。

The list of parasitoids inhabit in the centers of mass reproduction of the allied bark beetle Ips amitinus (Eichh.) in the Tomsk Region is given. Parasitoids were reared from the branches cut in the upper parts of the crowns to the Siberian pine Pinus sibirica Du Tour., inhabited by the allied bark beetle. The branches were collected in the centers of its mass reproduction in the Tomsk region, in the invasive part of the range of this xylophagous allied bark beetle. In addition to Ips amitinus, the branches were inhabited by Pityogenes chalcographus (L.), Pityogenes conjunctus Rtt., Pissodes piniphilus (Hbst), and Monochamus saltuarius Gebler. In total, 11 species of xylophagous parasitoids inhabiting branches were found, including 5 parasitoids of the union bark beetle: Coeloides ungularis (Thomson.), Dinotiscus eupterus (Walker), Tomicobia seitneri (Ruschka), Rhopalicus tutela (Walker), Roptrocerus xylophagoraum (Ratzeburg). Eubazus semirugosus (Nees), Spathius rubidus (Rossi), Eurytoma arctica Thomson, Tomicobia pityophthori (Bouček), Rhopalicus quadratus (Ratzeburg) were bred from the branches that dwelt Ips amitinus и Pityogenes chalcographus. Braconid Coeloides ungularis Thomson as the host of Ips amitinus is indicated for the rst time.
本文列出了托木斯克地区树皮甲壳虫(Ips amitinus (Eichh.))大量繁殖中心的寄生虫清单。寄生虫是从西伯利亚松树树冠上部剪下的枝条上饲养的。这些树枝是在托木斯克地区的大量繁殖中心采集的,位于这种食木质部异型树皮甲虫的入侵范围内。除了 Ips amitinus,树枝上还栖息着 Pityogenes chalcographus (L.)、Pityogenes conjunctus Rtt.、Pissodes piniphilus (Hbst) 和 Monochamus saltuarius Gebler。总共发现了 11 种栖息在树枝上的食木质寄生虫,其中包括 5 种寄生于联合树皮甲的寄生虫:Coeloides ungularis (Thomson.), Dinotiscus eupterus (Walker), Tomicobia seitneri (Ruschka), Rhopalicus tutela (Walker), Roptrocerus xylophagoraum (Ratzeburg).Eubazus semirugosus (Nees), Spathius rubidus (Rossi), Eurytoma arctica Thomson, Tomicobia pityophthori (Bouček), Rhopalicus quadratus (Ratzeburg) 是在栖息着 Ips amitinus и Pityogenes chalcographus 的树枝上繁殖的。Braconid Coeloides ungularis Thomson 是 Ips amitinus 的宿主,这还是第一次被指出。

The role of steppe marmots, or the bobak marmots, in the formation and maintenance of the structural and species diversity of steppe meadows is shown. Due to grazing, animals form small-grass meadows within their settlement. The marmot’s trophic activity hinders the development of tall grasses: Bromopsis inermis, Calamagrostis epigeios, Elytrigia repens etc. Without grazing,large grasses form cenotically closed groups and displaces most of the weakly competitive meadow plant species. During the growing season, marmots change the set of consumed grasses. This excludes the digression of the small-grass meadow in their settlement. Thanks to the burrowing activity marmot’s settlements appear in the meadows. Unique ecological conditions of marmot’s settlements contribute to the formation of microgroups of dry meadow species. In addition, annual and biennial plants, as well as nitrophilous, nemoral and boreal plants, which are not characteristic for steppe meadows, are actively introduced into marmot’s settlements.
图中展示了草原旱獭(或称波巴克旱獭)在形成和维持草原草甸的结构和物种多样性方面所起的作用。由于放牧,动物在其聚居地内形成了小草甸。旱獭的营养活动阻碍了高草的生长:Bromopsis inermis、Calamagrostis epigeios、Elytrigia repens 等。在没有放牧的情况下,大型牧草会形成封闭的群落,并取代大部分竞争力较弱的草地植物物种。在生长季节,旱獭会改变消耗的草群。这就排除了它们定居的小草草甸的可能性。由于旱獭的穴居活动,草地上出现了旱獭的聚居地。旱獭栖息地独特的生态条件有助于形成干燥草地物种的小群。此外,旱獭栖息地还积极引入了一年生和二年生植物,以及草原草甸不具备的亲硝植物、沼泽植物和北方植物。

The article presents the results of the study of benthic flora along the western coast of the Crimean Peninsula (Sevastopol region, Black Sea) in the summer of 2020. Hydrobotanical studies covered the water areas of Cape Tyubek, Lukull, VaiVai, Margopulo, Nemetskaya and Yazykovaya Balka. The flora included macroalgae of 74 species from the departments Chlorophyta, Heterokontophyta and Rhodophyta. The identified taxonomic composition was characterized by high species saturation of suprageneric taxa and low genus coefficient (1.1–2.0), coincidence of the proportion “order/family” in the divisions and in the whole algoflora, as well as “order/family/genus” in Heterokontophyta and Rhodophyta. The basis of taxonomic diversity was the following Rhodophyta (Ceramiales, Corallinaceae, Rhodomelaceae, Ceramiaceae), Chlorophyta (Cladophorales, Ulvales, Cladophoraceae, Ulvaceae), Heterokontophyta (Ectocarpales, Chordariaceae). Multispecies orders and families united from 55 to 88% of the total number of species found. High species diversity was characteristic of the genera Cladophora, Ulva, Polysiphonia and Ceramium. Seventeen species included in the national Red Data Books and international lists were found in the studied areas of the western coastal zone, which indicates the conservation significance of the study area. The large proportion of permanent species, their high joint contribution with additional species, the presence of maximum occurrence in a quarter of species (100%), and the average value of Jaccard’s coefficient (60%) testified to the spatial homogeneity of the species composition in the studied water area, which corresponded to relatively uniform habitat conditions of hydrobionts along the open sea coasts. Spatial changes in taxonomic composition were moderate (Cv = 9–26%). The difference in the extreme values of the absolute number of taxa was insignificant (by 30-50%). Among the departments, Chlorophyta was characterized by the lowest variation in the number of taxa, and Rhodophyta – by the highest. The increase in the difference between the extreme values of the absolute number of taxa was realized in the direction of orders < families < genera < species. The results of phytoindication indicate the warm-water character of the flora and the emerging trend of increasing trophicity of algal habitat in the study area.
文章介绍了 2020 年夏季对克里米亚半岛西海岸(黑海塞瓦斯托波尔地区)底栖植物区系的研究结果。水生植物研究覆盖了秋别克角、卢库尔、瓦伊瓦伊、马尔戈普洛、内梅茨卡亚和亚兹科瓦亚-巴尔卡的水域。植物区系包括叶绿纲、异叶绿纲和红叶纲的 74 种大型藻类。已确定的分类组成的特点是:超属类群的物种饱和度高,属系数低(1.1-2.0),各区和整个生物群中的 "目/科 "比例一致,异叶绿体和红叶植物区系中的 "目/科/属 "比例一致。分类多样性的基础是红叶植物界(角藻纲、珊瑚科、红藻科、角藻属)、绿叶植物界(叶绿藻纲、莼菜纲、叶绿藻科、莼菜科)和异叶植物界(外果皮植物界、脊索动物门)。多物种的目和科占发现物种总数的 55%至 88%。石花菜属、莼菜属、多石花菜属和 Ceramium 属的物种多样性很高。在西部沿海地区的研究区域发现了 17 个列入国家红色数据手册和国际名录的物种,这表明该研究区域具有重要的保护意义。永久性物种所占比例较大,它们与其他物种的共同贡献率较高,四分之一的物种出现率最高(100%),以及 Jaccard 系数的平均值(60%)证明了研究水域物种组成的空间均一性,这与公海沿岸水生生物相对均一的生境条件相吻合。分类组成的空间变化不大(Cv = 9-26%)。分类群绝对数量的极值差异不大(30-50%)。在各区中,叶绿体区(Chlorophyta)的类群数量变化最小,而红叶区(Rhodophyta)的类群数量变化最大。类群绝对数量极值之间的差异按目 < 科 < 属 < 种的方向增加。植物指示结果表明,研究区域的植物区系具有暖水特征,藻类栖息地的滋养程度呈上升趋势。

Literature data and new data on the distribution of bats of the Pipistrellus pipistrellus/pygmaeus complex in the Cis-Urals and the Urals are summarized. During the expeditionary work of 2015-2018 and 2023, the habitation of Soprano Pipistrelle P. pygmaeus was established in the Udmurt Republic, the Republic of Bashkortostan and the Orenburg region, and the search for Common Pipistrelle P. pipistrellus s. str., as well as in the adjacent territories of the Volga region, did not give a positive result. Previously cited in literary sources, information about the habitation of P. pipistrellus in the Cis-Urals and the Urals was not supported by museum copies, so they cannot be veri ed. In this regard, we believe that all indications of nds in the Cis-Urals and Urals Common Pipistrelle P. pipistrellus made by other authors should be attributed to the form P. pygmaeus. In total, we caught ten individuals of P. pygmaeus (6♀♀ad, 3♀♀ and 1♂ sad). In examined animals, morphometric indicators and external diagnostic signs turned out to be typical for the species. Soprano Pipistrelle is found in oodplain forests in lowland and low-mountain areas with heights up to 250 m above sea level. The Cis-Urals and Urals are included in the eld of breeding by females of P. pygmaeus, as evidenced by the ndings of adult females and subadalt. Adult males in the study area were not recorded. Beyond the Ural Range, the nds of P. pygmaeus are unknown, thus, the western foothills of the Urals are the eastern border of the distribution of the species. The seasonal movement routes and wintering sites are not known. In the Cis-Urals and Urals, Soprano Pipistrelle is a very rare, locally common species. To preserve populations and identify ecological features of the habitat of P. pygmaeus on the border of the range, it is advisable to conduct monitoring studies and add the species to the Red Books of the Udmurt Republic, the Republic of Bashkortostan and the Orenburg Region.
总结了关于琵琶蝠/琵琶蝠复合体在西乌拉尔和乌拉尔地区分布的文献数据和新数据。在 2015-2018 年和 2023 年的考察工作中,在乌德穆尔特共和国、巴什科尔托斯坦共和国和奥伦堡地区确定了高音琵琶蝠(Poprano Pipistrelle P. pygmaeus)的栖息地,对普通琵琶蝠(Popistrellus P. pipistrellus s. str.)以及伏尔加河地区邻近地区的搜寻没有取得积极成果。之前在文学资料中引用的关于琵鹭在西乌拉尔和乌拉尔居住的信息没有得到博物馆副本的支持,因此无法证实。在这方面,我们认为其他作者关于西乌拉尔和乌拉尔常见琵鹭栖息地的所有描述都应归于 P. pygmaeus。我们总共捕获了 10 只 P. pygmaeus(6♀♀ad,3♀♀ 和 1♂ sad)。在被检查的动物中,形态指标和外部诊断征象被证明是该物种的典型特征。槐鹬生活在海拔 250 米以下的低地和低山地区的原始森林中。从成年雌鸟和亚雌鸟的发现情况来看,顺乌拉尔和乌拉尔地区是雏杓鹬雌鸟的繁殖地。在研究地区没有记录到成年雄性。乌拉尔山脉以外,侏儒蛙的分布区尚不清楚,因此乌拉尔山脉西麓是该物种分布的东部边界。该物种的季节性移动路线和越冬地点尚不清楚。在西乌拉尔和乌拉尔,槐鹬是一种非常罕见的地方常见物种。为了保护该物种的种群并确定其分布区边界的生态特征,最好开展监测研究,并将该物种列入乌德穆尔特共和国、巴什科尔托斯坦共和国和奥伦堡州的红皮书中。
