Aim of this paper is to provide the first comprehensive synthesis about ground beetle (Coleoptera: Carabidae) distribution in high altitude habitats. Specifically, the attention is focused on the species assemblages living on the most common ice-related mountain landforms (glaciers, debris-covered glaciers, glacier forelands and rock glaciers) and the challenges, threats and opportunities carabids living in these habitats have to face concerning the ongoing climate warming. The suggested role of the ice-related alpine landforms, as present climatic refugia for cold-adapted ground beetles, is discussed. Finally, the needs to develop a large-scale High-alpine Biodiversity Monitoring Program to describe how the current climate change is shaping the distribution of high altitude specialists is highlighted.

In the current scenario of climate change, cold-adapted insects are among the most threatened organisms in high-altitude habitats of the Alps. Upslope shifts and changes in phenology are two of the most investigated responses to climate change, but there is an increasing interest in evaluating the presence of high-altitude landforms acting as refugia. Nebria germari Heer, 1837 (Coleoptera: Carabidae) is a hygrophilic and cold-adapted species that still exhibits large populations on supraglacial debris of the Eastern Alps. This work aims at describing the ecology and phenology of the populations living on supraglacial debris. To this end, we analysed the populations from three Dolomitic glaciers whose surfaces are partially covered by stony debris. We found that supraglacial debris is characterised by more stable colder and wetter conditions than the surrounding debris slopes and by a shorter snow-free period. The populations found on supraglacial debris were spring breeders, differently from those documented in the 1980s on Dolomitic high alpine grasslands, which were reported as autumn breeders. Currently, Nebria germari seems, therefore, to find a suitable habitat on supraglacial debris, where micrometeorological conditions are appropriate for its life-cycle and competition and predation are reduced.

Hosts of obligate avian brood parasites can diminish or eliminate the costs of parasitism by rejecting foreign eggs from the nests. A vast literature demonstrates that visual and/or tactile cues can be used to recognize and reject natural or model eggs from the nests of diverse host species. However, data on olfaction-based potential egg recognition cues are both sparse and equivocal: experimentally-applied, naturally-relevant (heterospecific, including parasitic) scents do not appear to increase egg rejection rates in two host species, whereas unnatural scents (human and tobacco scents) do so in one host species. Here I assessed the predictions that (i) human handling of mimetically-painted model eggs would increase rejection rates, and (ii) applying unnatural or natural scents to mimetically or non-mimetically painted model eggs alters these eggs’ respective rejection rates relative to controls. I studied wild American Robins (Turdus migratorius), a robust rejecter species of the eggs of obligate brood parasitic Brown-headed Cowbirds (Molothrus ater). There was no statistical evidence to support either prediction, whereas poorer color-mimicry was still a predicted cause of greater egg rejection in this data set. Nonetheless, future studies could focus on this and other host species and using these and different methods to apply and maintain the scenting of model eggs to more directly test hosts’ use of potential olfactory cues in the foreign-egg rejection process.

The intensively farmed fishponds of the Třeboň Basin in South Bohemia, Czech Republic host a substantial number Great Crested Grebe (Podiceps cristatus) pairs that nest later than the expected spring season and instead in summer, which may be associated with fishpond farming. A two-factor nested ANOVA of Great Crested Grebe egg and clutch characteristics showed no differences between spring (May-June) and summer (July - August) seasonal clutches. High egg total volume in spring nests was significantly related to both decreasing distance between nests and decreasing number of nests on the fishpond. The increase of total egg volume in summer nests was significantly related to the distance to the edge of littoral vegetation. There is no substantial difference between spring and summer egg characteristics, but total egg volume in spring nests is dependent on other characteristics that those in summer nests.

A finding of the lymnaeid species Ladislavella occulta (Jackiewicz, 1959) [Mollusca: Gastropoda: Lymnaeidae] in Hungary is reported, which is the first record of this snail in the country. The shells of L. occulta were found in 1989 in the marsh area of the Batorliget Nature Reserve. The current distribution of this species in Eastern and Central Europe is reviewed. It is hypothesized that L. occulta represents a relic species, whose origin may be traced back to the Pleistocene

Cryptic species are such evolutionary lineages that differ genetically but cannot or can only be hardly differentiated with traditional morphological methods, so they are classified as the same species. Several cryptic species have been discovered within the family Enchytraeidae and some of them have also been described formally. During the study of the enchytraeid fauna of South Korea, specimens were found which were identified as Bryodrilus ehlersi based on their morphological characters. This was an unexpected result, since this species is common in Northern and Central Europe but has not yet been found in the Far East. Sequence analysis of the mitochondrial cytochrome c oxidase subunit I gene, the nuclear histone 3 gene and the nuclear ribosomal ITS region showed unambiguously that the specimens collected in South Korea represent a different species. In this paper the description of this new cryptic species, Bryodrilus deogyunensis sp. n., is given with its comparison with the morphologically almost identical B. ehlersi.

There is limited data available concerning the effect of T-2/HT-2 toxin or deoxynivalenol (DON) on invertebrates such as springtails, and no data on their life history and oxidative stress. Control maize and DON or T-2 toxin contaminated maize were fed to Folsomia candida with a toxin content of 16324 mg DON kg–1 or 671 mg T-2 kg–1 maize. Ten to twelve days old animals were investigated in a life-history test and a stress protein test.T-2 toxin did not affect Folsomia candida in any measured parameters. The DON exposed group showed decreased growth and reproduction, and a higher survival rate. DON treatment resulted in lower protein content, while reduced glutathione content was higher than in control. It suggests that DON activated the glutathione-related detoxification pathway, which possibly causes a higher survival rate. The results also suggest that the oral toxicity of DON or T-2 is lower than through physical contact.For that reason, DON and T-2 toxin contaminated maize is not suggested to be used as green manure in the native state. Alternative solutions could be using mycotoxin contaminated maize for biogas production, or after decontamination by bacterial strains, it can be used as organic fertilizer.
关于T-2/HT-2毒素或脱氧雪腐镰刀菌醇(DON)对弹尾等无脊椎动物的影响的数据有限，没有关于它们的生活史和氧化应激的数据。对照玉米和DON或T-2毒素污染玉米分别饲喂毒素含量为16324 mg DON kg-1和671 mg T-2 kg-1的假丝叶虫玉米。对10 ~ 12天大的动物进行生活史测试和应激蛋白测试。T-2毒素对假丝酵母菌均无影响。DON暴露组生长繁殖下降，存活率提高。DON处理导致蛋白质含量降低，而还原性谷胱甘肽含量高于对照组。提示DON激活了与谷胱甘肽相关的解毒途径，这可能导致更高的存活率。结果还表明，DON或T-2的口服毒性低于物理接触。因此，DON和T-2毒素污染的玉米不建议在原生状态下用作绿肥。替代的解决方案可能是使用霉菌毒素污染的玉米生产沼气，或者在菌株净化后，它可以用作有机肥料。

Over the past decades, spring temperatures have increased in temperate regions, which resulted in birds arriving earlier in spring. Nonetheless, the timing of some species’ spring migration relies on endogenous rhythms that are not affected by climate change. In this study, we analysed changes in the spring arrival dates of 36 bird species over two periods in 22 towns and villages in Southeast Hungary and West Romania. The first period covered the national spring migration counts between 1894 and 1926, while the second period took place between 2005 and 2019 and is based on our recent observation data. Our results show, that the average spring arrival dates of most long-distance migrant species have not changed significantly over the past 100 years. In contrast, in cases of medium and short-distance migrants, most species arrive earlier recently than in the past. This may be caused by the fact, that the migration habit of long-distance migrants is characterized by strong genetic determinants, so they can not react as quickly to the warmer spring weather in Europe as the medium and short-distance migrants. However, in cases of some long-distance migrants, the timing of spring migration changed due to the drying of wintering grounds.

Nonetheless, the timing of some species’ spring migration relies on endogenous rhythms that are not affected by climate change. In this study, we analysed changes in the spring arrival dates of 36 bird species over two periods in 22 towns and villages in Southeast Hungary and West Romania. The first period covered the national spring migration counts between 1894 and 1926, while the second period took place between 2005 and 2019 and is based on our recent observation data. Our results show, that the average spring arrival dates of most long-distance migrant species have not changed significantly over the past 100 years. In contrast, in cases of medium and short-distance migrants, most species arrive earlier recently than in the past. This may be caused by the fact, that the migration habit of long-distance migrants is characterized by strong genetic determinants, so they can not react as quickly to the warmer spring weather in Europe as the medium and short-distance migrants. However, in cases of some long-distance migrants, the timing of spring migration changed due to the drying of wintering grounds.","PeriodicalId":55558,"journal":{"name":"Acta Zoologica Academiae Scientiarum Hungaricae","volume":"66 1","pages":"283–298-283–298"},"PeriodicalIF":0.8,"publicationDate":"2020-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42412766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
