A proper understanding of tissue and cell structure is of great importance for correct biological inferences, and particularly so in organisms used as research models. Nothobranchius spp. are short-lived freshwater fish species which are promising model organisms for toxicology, evolutionary ecology, aging and regeneration research. Nevertheless, studies examining Nothobranchius histology have focused exclusively on a few specific organs and associated functional impairments, and there is a lack of reference material on the natural state and appearance of tissue structure. Here we present a detailed histological map of the major body organ systems, which was built from 300 Nothobranchius spp. specimens. This overview offers baseline material for comparative histological studies and provides insights into functional and anatomical aspects of organs related to the unique life cycle of Nothobranchius spp.","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49460463","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}

This trend continued in the 20th Century when international trade and the transport of people and goods greatly accelerated. Initially the negative effects of deliberate and accidental introductions of alien species were not fully recognised. One of the first insightful works on the subject was the book by the famous British ecologist, Charles Elton, “The Ecology of Invasions by Animals and Plants”, published in 1958. In the 1980s the Scientific Committee on Problems of the Environment (SCOPE) focused on the causes, impacts, and management of invasions, but a breakthrough came after 1992 when, during the United Nations Conference on Environment and Development (UNCED), also known as the Rio de Janeiro Earth Summit, biological invasions were identified as one of five threats to biodiversity (Meyerson & Simberloff 2021). The Convention on Biological Diversity, Article 8, which was formulated at the Rio summit, committed signatory nations to prevent, control, and eradicate potentially harmful alien species. Following this event, the number of publications on biological invasions began to increase exponentially (Ricciardi & MacIsaac 2008, Richardson & Pyšek 2008). Understanding the causes of expansion, especially of an invasive nature, and the consequences for local biota stimulated a generation of researchers to undertake studies aimed at recognizing the principles and general patterns related to this problem (e.g. Lodge 1993, Moyle & Light 1996, Vitousek et al. 1996, Williamson & Griffiths 1996, Richardson & Pyšek 2008), and to develop a common, consistent nomenclature (Copp et al. 2005).","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46006732","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}

Invasive carps are ecologically and economically problematic fish species in many large river basins in the United States and pose a threat to aquatic ecosystems throughout much of North America. Four species of invasive carps: black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), are particularly concerning for native ecosystems because they occupy and disrupt a variety of food and habitat niches. In response, natural resource agencies are developing integrated pest management (IPM) plans to mitigate invasive carps. Control tools are one key component within a successful IPM program and have been a focal point for development by governmental agencies and academic researchers. For example, behavioural deterrents and barriers that block migratory pathways could limit carps range expansion into new areas, while efficient removal methods could suppress established carp populations. However, control tools are sometimes limited in practice due to uncertainty with deployment, efficacy and availability. This review provides an overview of several emerging modelling approaches and control technologies that could inform and support future invasive carp IPM programs.","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41935332","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}

We analysed and compared the structure and parameters of the songflight calls of expansive Pipistrellus kuhlii and Pipistrellus lepidus, that recently colonized Central Europe from the south and east, respectively. Bat calls were recorded mainly in urban areas of Central Europe and the Balkans, including a narrow zone of these species' recent parapatric or sympatric occurrence (around the Carpathians and the eastern part of the Pannonian Basin). The newly described songflight calls of P. lepidus consist of more elements (median 6), are longer (mean 56.4 ms) and of a higher frequency of maximum energy (mean 25.7 kHz) than those of P. kuhlii (median 3, mean 41.0 ms and mean 14.0 kHz, respectively). This finding provides new evidence that P. lepidus represents a different species, in accordance with results from previous genetic and morphological studies. Reported differences in songflight calls permit the acoustic discrimination of P. kuhlii and P. lepidus, which is not possible based on overlapping parameters of their echolocation calls. Our findings enable distributional and ecological studies of these two species, based on acoustic methods, in the context of their rapid European expansion and the local co-occurrence.","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46559742","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}

This study examined escape behaviour of hooded crows, Corvus cornix, in an urban environment, in Belgrade, Serbia, with the goal of assessing the effect of breeding season on components of escape behaviour; flight initiation distance (FID), distance fled (DF), and escape method (flying vs. running/walking). Using GLMMs, it was shown that FID was longer during the breeding season, and increased with alert distance. DF was significantly influenced by escape method, with birds escaping for distances greater than 10 m more often when flying, whereas escape method itself was significantly influenced by FID, with birds escaping more often by flying at greater distances from an approaching predator. The majority of individuals (78%) fled for distances < 10 m after initiating escape, and escaped by walking or running (67%). Our results show that hooded crows, although adapted to living in highly urbanized environments, may be more risk-averse during the breeding season, which may allow them to more successfully take care of their young.","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46855019","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}

Miller","doi":"10.25225/jvb.21064","DOIUrl":"https://doi.org/10.25225/jvb.21064","url":null,"abstract":"Abstract. An information-theoretic approach was used to evaluate non-native freshwater fish species introduced to insular habitats of Hawaii and Guam comparing successful establishments vs. failures. Since the late 1800s, as many as 81 non-native freshwater fish species have been recorded as introduced to Hawaii and Guam (combined) and 50 (62%) of these are documented as having one or more established populations. We examined eleven independent variables to investigate establishment success by creating 21 a priori logistic regression models ranked using Akaike's Information Criterion adjusted for small sample size. An additional eight post-hoc models were included that comprised the best a priori model and various combinations of individual variables. The best overall model of establishment probability included effects of taxonomic affinity (family membership), prior establishment success on other tropical islands, and hypoxia tolerance. Establishment success in Hawaii and Guam was highest for those species established on many other islands, and according to our best model air-breathing fishes were more likely to become established. Six fish families, each with from three to 18 species introduced to Pacific islands, were highly successful at establishment: Cichlidae (16 established of 18 species introduced), Poeciliidae (seven of eight), Cyprinidae (four of seven), Centrarchidae (four of four), Clariidae (three of three), and Loricariidae (three of four). Those that successfully established include both small and moderately large-bodied taxa, while representing a diverse array of other morphological and life-history traits. Pathways and motives associated with fish introductions in the Pacific have been linked to desires to develop aquaculture, enhance wild stocks of food, sport, and bait fishes, for use as biological control agents, or are linked to the ornamental fish trade. We found that many established species were introduced via multiple pathways (up to eight) and our analyses suggest that the combination of prior establishment success on other tropical islands and presence of non-native fishes in multiple pathways was indicative of high propagule pressure. Our study results and conclusions on Pacific tropical island introductions are in general agreement with previous studies on non-native freshwater fishes in other regions of the world and similar to observations in continental ecosystems and temperate zones.","PeriodicalId":48482,"journal":{"name":"Journal of Vertebrate Biology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48016531","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}
