Yet, cliffs are difficult to sample, and rock-dwelling lichens can be challenging to identify; therefore, cliff lichens are often excluded from biodiversity studies. This omission creates fundamental gaps in our understanding of cliff lichens that lead to underestimation of overall community diversity. This study addresses one such gap by asking a basic question: do lichen communities on cliffs differ from rock-dwelling lichen communities in forests? To answer this question, we compared lichen communities from three cliffs in the Linville Gorge (North Carolina, USA; 369 m<sup>2</sup> of cliff face surveyed) to rock and soil-dwelling lichen communities in forested plots across the same region (Southern Appalachian Mountains, USA, Alabama to North Carolina; 198 1-hectare forested plots). Forest plots were further divided into three groups based on elevation, proximity to Linville Gorge cliffs, and location within the state of North Carolina. A total of 225 rock or soil-dwelling lichen species were found in forest plots throughout the study area, while 104 species were found on cliffs. Two rare cliff-specialist species, <em>Canoparmelia alabamensis,</em> and <em>Chrysothrix susquehannensis,</em> were locally abundant on the studied cliffs but absent from surrounding forests. Our results show that cliffs support 20% of regional rock-dwelling lichen diversity, and that these cliff communities are distinct from those in forests. The high diversity, occurrence of unique species, and presence of rare lichens on cliffs indicate that cliff lichens should be included in biodiversity inventories and stewardship plans. To support this inclusion, we provide the first checklist for the lichens of Linville Gorge. Checklists like this one, including both cliff and non-cliff lichens, provide data on regional diversity and rarity that inform lichen conservation and rock climbing management.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"81 ","pages":"Pages 112-120"},"PeriodicalIF":3.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142743120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also explored the validity of growth- and stress-related phytohormones as functional traits to evaluate stress acclimation responses in the field. We compared the response of plants, considering both mother rosettes and newly produced clones, to a very extreme summer drought event occurring in small cliffs in Les Guilleries mountains (NE Spain). We measured various stress makers in the field together with hormonal profiling through a metabolomic approach using liquid chromatography coupled to tandem mass spectrometry. Results showed that clonal propagation was arrested during the study period and revealed a 100-fold increase in abscisic acid content from spring to summer both in mothers and new clones, concomitantly with reductions in relative water content, which decreased by 20% only. The stress-related bioactive jasmonate, jasmonoyl-isoleucine increased simultaneously with abscisic acid, while growth-related hormones, including bioactive cytokinins (2-isopentenyl adenine and <em>trans</em>-zeatin) decreased from spring to summer, which was consistent with growth arrest. It is concluded that <em>S. tectorum</em> adjusts recruitment of new clones during periods of low water availability and withstands extreme drought events during the summer (preventing severe cell turgor loss at soil water contents below 2% and temperatures above 43 ºC) by successfully activating a complex hormonal response that underlies the great capacity of this species to survive extreme climatic events.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"81 ","pages":"Pages 96-105"},"PeriodicalIF":3.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Species reintroductions and population reinforcements (i.e. conservation translocations) are an important component of conservation, yet are rare in urban environments, possibly because of perceived risks in highly modified and complex social-ecological urban systems. Here we review the literature describing urban conservation translocations to provide guidance for their effective implementation. We find that urban translocations have been performed for a variety of aims including focal species conservation, improvements in ecosystem functions in the later stages of restoration projects (e.g. seed dispersal in revegetated sites) and for site remediation (e.g. organic pollution removal), and enhancing human-nature connections. Conservation translocations were found in a range of urban habitat types including formal and informal greenspaces, grey spaces, streams, ponds, and marine environments, ranging from near-historic conditions (e.g. remnant/restored sites) to highly modified novel/designed systems. Barriers and enablers varied between terrestrial and aquatic release sites, with predators, habitat suitability, and leaving release sites being more important in terrestrial sites and disturbance (flooding) regime and pollution being more important in aquatic sites. A range of techniques have been applied to mitigate these barriers. Success rates in urban translocations are high (&gt;90 %) and comparable to conservation translocations in general, suggesting they can contribute to urban biodiversity conservation by assisting species to overcome dispersal barriers and occupy otherwise suitable urban habitats. However, evaluation methods vary widely between urban translocation studies. There is also a need for longer-term monitoring of translocation success that might be achieved simultaneously while enhancing human-nature connections through citizen science programs.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"81 ","pages":"Pages 85-95"},"PeriodicalIF":3.0,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Movement ecology aims to understand the causal relationships between environmental conditions, animal movements, interactions and coexistence of species, as well as effects of movement patterns on ecosystem processes. In contrast, practical conservation primarily aims to understand organisms' movements to improve species management, protection, legal monitoring or risk assessment, and species-habitat interactions. Despite the many studies of movement ecology in basic and applied sciences as well as in practical conservation in terrestrial ecosystems, knowledge gain and transfer between disciplines are limited. Better integration and linking of both disciplines would result in diverse science-practice synergies, but these are currently constrained by numerous challenges that need to be overcome. From a scientific perspective, knowledge gain from practice is limited by a multitude of case studies with limited spatial and temporal resolution. This can be overcome by improving access and combining the diversity of data for a research area that often deals with small sample sizes. From a practical perspective, the movement ecology framework, which is often dedicated to basic research, as well as the access and language barriers to scientific publications, limit the application of scientific results. Here movement ecologists should be encouraged to consider conservation issues more frequently in addition to basic research. The transfer of scientific results could be improved by scientists providing sufficient details for practitioners to extract relevant information and publish at least an open-access abstract in local language with clear management recommendations. Further, the use of open-access repositories allows both, scientists and practitioners an overview of the multitude of studies and helps to share data in order to derive general conclusions. Challenges impacting science and practice can be conceptual, organisational and technical in nature. Such constraints can be overcome, for example, by providing verified trapping protocols, using recent technological developments and analytical methods combined with trainings on these state-of-the-art tracking and analysing tools. In particular, collaborative project planning between scientists and practitioners can help to improve the sampling design of applied studies and broaden the data base for science in order to significantly advance the movement ecology framework and gain comprehensive knowledge for practical conservation.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"81 ","pages":"Pages 59-65"},"PeriodicalIF":3.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between population grain yield and individual fitness (mean individual grain yield in mixture) of genotypes was resource dependent in a way that is consistent with the theory: when resource levels are low and limit individual growth directly, individual and population yield are positively correlated. When resource levels are high and the growth of individual plants is limited by competition for these resources, the relationship between individual fitness and population yield becomes negative. There was evidence for the unimodal relationship at the intermediate resource level. Old cultivars had higher fitness than newer cultivars at all three resource levels.
