Nevertheless, there has been little follow up research on the ManhattAnt since its discovery, and it has yet to be formally identified. Here we use genetic and morphological approaches to confirm the identity of the ManhattAnt and characterize its introduced range and colony structure. Results from genetic analyses placed the ManhattAnt within the <i>Lasius emarginatus</i> species complex, and morphological comparisons ruled out closely related species to identify the ManhattAnt as the European ant <i>L. emarginatus</i> with 93–99% certainty depending on the nest sample. Since its initial discovery in the region, the ManhattAnt has become one of the most common ants in New York City and has spread at a rate of 2 km/yr into New Jersey and onto Long Island. Based on the climate it inhabits within its native range, <i>L. emarginatus</i> could expand to cover much of the eastern United states from Massachusetts to Georgia. Although many successful invasive ants display supercoloniality with little aggression between neighboring nests, we found no evidence that <i>L. emarginatus</i> colonies in New York City are supercolonial. Continued monitoring of <i>L. emarginatus</i> is warranted, as it has been increasingly reported as an indoor pest and is known to form mutualisms with honeydew producing pests of street trees.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"29 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141170399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it returned to the Santa Cruz River in 2015 independently of these actions, which prompted concerns that a non-native <i>Poeciliopsis</i> lineage had been introduced from Mexico. Some Gila topminnow populations in Mexico are sympatric with <i>P. monacha-occidentalis</i>, which is an exclusively female taxon that originated from historical hybridization between <i>P. occidentalis</i> and headwater livebearer (<i>P. monacha</i>). This hybrid taxon reproduces through hybridogenesis, which is a unique mode of sexual reproduction in which half of one parent’s genome is inherited without recombination. This unique property was leveraged to identify hybridogens among 868 individuals from Arizona, USA using common genetic markers (i.e., nuclear microsatellite and mitochondrial sequence data). We described methods for <i>P. monacha-occidentalis</i> identification and conducted population genetic analysis of Santa Cruz River <i>P. occidentalis</i> populations to infer their possible origins. We concluded that human-mediated introduction was the most probable explanation for the current Santa Cruz River <i>P. occidentalis</i> and <i>P. monacha-occidentalis</i> presence. Contemporary diversity may be explained by four introduction events. Population ancestry estimates indicate that <i>P. monacha-occidentalis</i> may have hybridized with two <i>P. occidentalis</i> lineages in the Santa Cruz River. Variable prevalence of <i>P. monacha-occidentalis</i> was noted in two river sections, but the conservation implications of this hybridization are unclear.

It adversely affects native plant and animal communities, but its ecosystem-level effects, particularly on hydrology, are little known. Since milkweed has an extensive, deep root system and large, broad leaves, we assumed a negative effect on the soil moisture content of the hosting ecosystem. Following the before-after control-impact protocol, we first compared the soil moisture content of the top 120 cm of the soil under seven milkweed stands to that of non-invaded reference sites. We then treated half of the stands by mechanically removing all aboveground milkweed biomass and repeated the comparative soil moisture measurements. We found that milkweed stands had significantly drier soils than reference grasslands during the growing season, but the soil under milkweed stands recharged to the level of the references in autumn and winter. However, the amount of moisture needed for this recharge was lost from deeper percolation to groundwater. Milkweed treatment prevented the depletion of moisture during the growing season, saving 21.6 l m⁻² of water on average. Treatment did not affect non-milkweed plant biomass, thus, moisture patterns could fully be attributed to the milkweed stands. Our results reinforce the importance of milkweed suppression in invaded grasslands, as, besides enabling the recovery of the native grassland ecosystem, it promotes groundwater recharge, which is particularly important in the dry regions of Central Europe, currently facing severe aridification due to climate change and unfavourable land use trends.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"34 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141170396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accumulation of anthocyanins in stems under low temperature conditions exhibits strong cold tolerance, and therefore may be one mechanism supporting the northward spread of the species. However, the role and synthesis mechanism of anthocyanins in the stems of <i>S. trilobata</i> when confronted with low temperature stress are still unclear. Field experiments have shown that compared to in summer, the stems of <i>S. trilobata</i> significantly accumulated anthocyanins to cope with winter. Further short-term low-temperature treatments (0 °C) were conducted on red and green stems of <i>S. trilobata</i>, and the results showed that the red stems exhibited lower levels of reactive oxygen species, membrane damage, and chlorophyll fluorescence changes compared to the green stems. In an indoor low-temperature control experiment, it was observed that <i>S. trilobata</i> exhibited significant accumulation of callus in the periderm of its stems compared to <i>S. calendulacea</i>, which subsequently resulted in increased levels of sucrose, glucose, and fructose contents. Furthermore, there was a significantly induced higher levels of abscisic acid and cytokinin in <i>S. trilobata</i> stems under low temperatures. Under the joint regulation of these carbohydrates and hormones, the key structural genes associated with anthocyanins synthesis pathway in <i>S. trilobata</i> stems were more strongly induced compared to <i>S. calendulacea</i>. The upregulation of <i>CHS</i>, <i>CHI</i>, <i>F3H</i>, and <i>DFR</i> gene expression levels in <i>S. trilobata</i> was higher than that of native species, which directly leads to the accumulation of more anthocyanins in the epidermis of the stem of <i>S. trilobata</i>, thereby reducing the degree of oxidative stress and maintaining normal growth under low temperature. In summary, anthocyanins play an important light filtering role in the response of <i>S. trilobatas</i> stem to low temperature stress, which is one of the important mechanisms for its successful invasion into southern China. In the context of global climate change, we need to increase our vigilance against further invasion of <i>S. trilobata</i> into colder inland regions such as temperate regions.

To investigate whether the distribution of <i>T. officinale</i> is affected by the tendency of buildings to create warm, sheltered microenvironments, we surveyed the abundance of both dandelion species relative to existing structures in town. We established transects extending up to 5 m from each side of 23 buildings, and recorded the number of plants in 50 cm × 50 cm quadrats along each transect. We found that <i>T. officinale</i> performed better on the south sides of buildings, that flowering decreased away from buildings, and that these effects were stronger for <i>T. officinale</i> than the native <i>T. lacerum</i>. Soil temperatures were warmer on the south rather than on the north-facing sides, providing a possible explanation.

Invasive alien conifers are weeds that are not only costly to manage, but consistently reinvade after management efforts. Understanding how many seeds survive to germinate is a key part in understanding the weed life cycle puzzle. Here we investigated the contribution that seed predators have on reducing invasive alien conifer seed survival across both invaded and uninvaded habitats in Aotearoa New Zealand. We combined quantitative and qualitative experiments to measure seed predation across invaded and uninvaded habitats, as well as to identify which fauna are the most prolific seed predators. We utilised ex-situ empirical evidence with in-situ observations to provide realistic impacts from different seed predator species. We found that introduced mammals, particularly rodents, were the primary seed predators of invasive conifers. Seed predation pressure was highest in herbicide treated invasive alien conifer forests, indigenous beech forests, and managed pasture containing grazing livestock. Indigenous tussock areas support fewer vertebrate seed predators and as a result are particularly vulnerable to conifer invasion. The majority of seed predation occurs within the first two weeks post-dispersal. These results suggest that introduced mammal control operations, which are essential to protect endemic New Zealand species, will likely result in increasing invasive conifer populations by reducing seed predation pressure. Seed predation varies greatly between habitats, suggesting invasion and reinvasion rates are higher in ungrazed areas of lower forest density that support fewer introduced mammals.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"24 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140936681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total, more than 2200 people were surveyed, belonging to nine different stakeholder groups that are in contact with invasive species (hunters and members in hunting associations, farmers, members of environmental and conservation organizations, members in allotment garden clubs, animal welfare supporters, divers, employees in zoological gardens, administrative employees in the regulatory authority, speleologists). It was found that the number of invasive animal and plant species in Germany was roughly correctly estimated in all groups, but the economic damage caused by invasive species was substantially underestimated.

In all surveyed groups, there was a notable level of interest in invasive species, and they were commonly regarded as environmental issues.

Invasive wild pigs (<i>Sus scrofa</i>) are among the most prolific invaders on the planet, causing billions of dollars in agricultural and environmental damage annually. Newly introduced to Canada in the 1980s, we examined wild pig invasion potential across the northern prairies from western Canada into the currently wild pig-free northern U.S. states. We used GPS collar data collected in the Canadian prairies to quantify resource selection and incorporated results into an electric circuit theory framework to evaluate potential regional landscape connectivity. While available landcover types in this region were dominated by crops and grasslands, wild pigs were predominately located in deciduous forest, crops, and wetlands. Resource selection modelling indicated wild pigs selected deciduous forest and wetlands over other landcover types. These selection tendencies resulted in areas at greater risk of occupation in an intermixture dominated by crops interspersed with waterbodies and deciduous forest fragments, which facilitated movement. Given the pervasiveness of this intermixture across the northern prairies, there was a high potential for invasive wild pigs to move throughout much of the region with areas in southern Saskatchewan and Manitoba, northeastern Montana, North and South Dakota, and western portions of Minnesota being particularly vulnerable.
