“…Such demographic history is expected for thermophilous organisms, which have likely faced unfavourable environmental conditions and population contractions during the coldest stages of the Pleistocene and demographic expansions coinciding with warm interglacials. A rapid postglacial expansion has been suggested for the largely co‐distributed white‐headed duck based on mtDNA (Muñoz‐Fuentes et al., 2005 ) and analogous demographic profiles have also been inferred based on genomic data for other thermophilous organisms with similar distributional ranges such as the Moroccan locust ( Dociostaurus maroccanus ; González‐Serna et al., 2020 ) and the Eurasian wild pea ( Pisum sativum ; Hellwig et al., 2022 ).…”

Genetic assessment of species that have experienced dramatic population declines provides critical information that is instrumental for the design of conservation recovery programs. Here, we use different sources of molecular data (mtDNA and ddRAD‐seq) to evaluate the genetic status of wild and captive populations of marbled teal (Marmaronetta angustirostris), a duck species classified as critically endangered in Spain and near threatened at a global scale. First, we determined the evolutionary and demographic trajectories of the wild population from Spain and the currently much larger population from Iraq, which is also the documented source of European zoo stocks. Second, we evaluated the suitability of the different captive populations for ongoing restocking programs in Spain and assessed their potential impact on the genetic composition of wild populations. Populations from Spain and Iraq were assigned to distinct genetic clusters, albeit with an overall low level of genetic differentiation, in line with their recent divergence (<8000 years ago) and lack of phylogeographic structure in the species. Demogenomic inferences revealed that the two populations have experienced parallel demographic trajectories, with a marked bottleneck during the last glacial period followed by a sudden demographic expansion and stability since the onset of the Holocene. The wild population from Spain presented high levels of inbreeding, but we found no evidence of recent genetic bottlenecks compatible with the human‐driven decline of the species during the past century. The captive populations from the two Spanish centers involved in restocking programs showed genetic introgression from European zoos; however, we found limited evidence of introgression from the zoo genetic stock into the wild population from Spain, suggesting captive‐bred birds have limited breeding success in the wild. Our study illustrates how ex situ conservation programs should consider the genetic distinctiveness of populations when establishing breeding stocks and highlights the importance of genetically assessing captive populations prior to reinforcement actions.

“…The insect is extremely voracious, has a high fecundity allowing it to quickly build large populations and disperse over long distances (Latchininsky, 1998; CABI, 2020; González-Serna et al 2020). When forming swarms under suitable conditions, they can cause substantial damage to more than 50 crops, and can develop over 150 plant species (Latchininsky, 1998;González-Serna et al 2020). This is not only problematic for farmers, the economy and food security, but for the environment in general, as the insect can damage thousands of hectares of native grasslands (Latchininsky, 1998) Although not all non-native Orthoptera species are considered as established in Europe, anecdotal evidence of impacts does exist for several species, while others have already established European populations and/or spread substantially.…”

Orthoptera encompasses 29,000 species. Due to their ability to migrate long-distances through hitchhiking or active dispersal but also due to their wide dietary spectrum, several orthoptera species can pose a phytosanitary threat. Despite information being scarce and contrasting among sources, we compiled literature on non-native Orthoptera species in Europe for this scoping review. We identified 41 relevant species, 35 are non-native (non-native to Europe n = 8, partly native to Europe n = 21, native range unknown/no information available n = 6), two arguably invasive species to Europe due to proven impacts, two are questionable and another two cryptogenic. Of these, 23 species are considered established. The two invasive orthopterans were the Moroccan Locust Dociostaurus maroccanus and the Desert Locust Schistocerca gregaria, which are invasive in several European countries. Non-native orthopterans can react very positively to climate warming, resulting in expanding geographical distributions. Furthermore, the number of invasive orthopterans in Europe is likely higher due to a paucity of assessments, increasing introduction rates, and observable impacts on agriculture as well as native species. While e.g., the Migratory Locust Locusta migratoria causes large-scale damage to crops by forming swarms, the southern oak bush cricket Meconema meridionale has a negative impact on native species, but neither species is listed as invasive. Besides this, there are other non-native Orthoptera species that could become invasive given increasing reproduction rates due to suitable conditions. Globalization and rising temperatures due to global warming are both increasing introduction rates and concomitantly the availability of suitable locations for reproduction, successful establishments, and finally swarm building. This will increase the probability of damages to agriculture, thus the economy and native biodiversity, eventually endangering human well-being. It is therefore important to monitor and study the invasiveness and impacts of non-native Orthoptera species to develop efficient management or preventive mitigation strategies.
