To understand the success of invasive alien species, it is necessary to evaluate the site-specific eco-evolutionary challenges they face in their new environments. We explored whether the rearrangement of genetic diversity is linked to the invasiveness of Prosopis juliflora by (i) comparing different stages of invasion (founding vs invasive populat...
Although invasive alien species have long been recognized as a major threat to nature and people, until now there has been no comprehensive global review of the status, trends, drivers, impacts, management and governance challenges of biological invasions. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)...
The context‐depency of biological invasions makes it difficult to understand why some species become succesfull invaders and others not. Such understanding requires studying closely‐related invasive and non‐invasive alien taxa sharing the same introduction history in the same environment. We identified this unusual situation in Kenya where the indi...
During the Anthropocene, humans are changing the Earth system in ways that will be detectable for millennia to come [1]. Biologically, these changes include habitat destruction, biotic homogenization, increased species invasions, and accelerated extinctions [2]. Contemporary extinction rates far surpass background rates [3], but they seem remarkabl...
The ability to reproduce via multiple strategies is crucial for the invasion success of alien plant species. Here, we use Carpobrotus taxa (species and hybrids) to explore how trade-offs between and within these strategies may influence plant invasion dynamics. Native to South Africa, Carpobrotus plants are globally prominent in coastal ecosystems,...
The genus Carpobrotus N.E.Br. comprises between 12 and 25 species, most of which are native to South Africa. Some Carpobrotus species are considered among the most damaging invasive species in coastal dune systems worldwide. In their introduced areas, these species represent a serious threat to native species and significantly impact soil condition...
Asare-Nuamah et al. (2022) and Koffi et al. (2020) found that almost 90 per cent of their sampled farmers from Ghana used synthetic pesticides for fall armyworm control. Tambo et al. (2020) and Houngbo et al. (2020) also reported that 87 per cent and 91 per cent of sampled farmers in Rwanda and Benin, respectively, applied synthetic pesticides to c...
Case studies of the role of national and international networks and
regional partnerships in the management of the Invasive Alien Species.
Oryctolagus cuniculus (rabbits) biological control in Australia.
Some examples of specific surveillance include the Mamalu Poepoe programme, which is coordinated through the Hawaii Invasive Species Council 1 targeting invasive ants, mosquitoes, coconut rhinoceros beetle and Africanized bees at airports (Kaufman & Atwood, 2019). The main objective of the programme was to provide baseline data on invasive ants at...
The International Plant Protection Convention (IPPC) International Standards for Phytosanitary Measures (ISPMs) greatly assist in management strategies by providing global standards in plant health management. ISPMs cover a wide range of topics, including: pest risk analysis, surveillance, phytosanitary pest status, pest reporting, regulated pest l...
According to Island Conservation’s Database of Island Invasive Species Eradications (DIISE, 2018), there have been over 1,500 eradication attempts of vertebrate alien species. As a result, 38 mammal species have been eradicated, in almost 1,100 events, with an 88 per cent success rate on 798 islands followed by 9 bird species, in 22 events, with an...
Indigenous peoples may not use more western terms of “management” and “restoration” when working to change the impacts of invasive alien species in their country, landscapes and culturally and spiritually important places. Where Indigenous Peoples care for their traditional lands impacted by invasive alien species, they do not use scientific termin...
Species-based management technologies for Invasive Alien Species.
Executive summary
1. Substantial knowledge, options and experience in management of biological invasions exist at the regional, national and local levels (well established) {5.2, 5.3, 5.4, 5.5, 5.6}. Key challenges for the effective implementation of biological invasion management include developing appropriate policies and regulations to support m...
To eliminate hull biofouling and niche areas fouling, different tools and technologies have been developed in line with following the International Maritime Organization Guidelines on biofouling (The Marine Environment Protection Committee, 2011). Vessel in-water cleaning or treatment is recognized as an important and practical tool to maintain a v...
Summary of surveillance and diagnostic technologies for invasive alien species
management.
Earth observation-remote sensing detection-Recent growth in personal mobile computing has led to improvements in size and energy efficiency of electronic sensor devices, enabling their deployment on small-sized animals. Dubbed "One Giant Leap for Wildlife Tracking", lightweight telemetric tags have been deployed on hummingbirds, pigeons, toucans, a...
Results of characterization of invasive alien species management by Indigenous Peoples and local communities based on 76 case studies (Table SM.5.1). Focus of management, ecosystems where management was conducted, managed taxa and motives for management were shown with the frequency of mention, frequency of percentages and percentage of cases repor...
Pathway surveillance tolls and technologies.
Knowledge of the introduction history and spread dynamics of invasive species can provide important insights for management (Ens et al. in Environ Rev (in press), 2022), however such information is often unavailable for accidental introductions. Here we infer how the European shore crab, Carcinus maenas , and its congener, the Mediterranean shore c...
Accurate taxonomic identification of alien species is crucial to detect new incursions, prevent or reduce the arrival of new invaders and implement management options such as biological control. Globally, the taxonomy of non-native Prosopis species is problematic due to misidentification and extensive hybridization. We performed a genetic analysis...
Here, I studied the drivers of spread and the mechanisms underlying their invasion success, including hybridization, rapid evolution and plasticity.
PREMISE OF THE STUDY: Knowledge about the introduction history (source(s), number and size of introduction events) of an invasive species is a crucial prerequisite to understand invasion success and to facilitate eective and sustainable management approaches, especially for eective biological control. We investigated the introduction history of t...
"El libro está estructurado en base a fichas que resumen de manera simple los aspectos más básicos para la identificación de las especies y su historia natural. Cada ficha muestra una descripción de los caracteres diagnósticos y ecológicos de la especie, fotografías de cada especie, y se enfatiza en cada caso los impactos y los procedimientos que s...
Myotis atacamensis is a vespertilionid bat known from western Peru to northern and central Chile, where it is usually associated with coastal deserts. Here, we report the southernmost record of the species, extending its geographical distribution by 160 km. This represents the first observation of M. atacamensis in the temperate sclerophyllous fore...
Aquatic invasive species are a major threat to native freshwater ecosystems and cause enormous ecological and economic damage worldwide. Didymosphenia geminata (Lyngbye) M. Schmidt is an emerging invasive aquatic species that is spreading aggressively in Southern South America. Using niche analysis and species distribution models (SDMs), we examine...
Myotis atacamensis is a poorly known bat species endemic to the central portion of the pacific coast of South America, where it is known from the province of Lambayeque, Peru (Latitude 5oS) to the province of Elqui (Latitude 30oS), Chile. Here, we report the first record of M. atacamensis for the province of Choapa (Latitude 31oS, Coquimbo Region)...
Negative photoblastism is defined as the inhibitory effect of light on seed germination. This effect can be modulated by abiotic variables, such as temperature, light condition and water potential. This conditions change notoriously at higher altitudes, could promote differentiations in the photoblastic response among populations. Also, this physio...

Este efecto puede ser modulado por variables abióticas, tales como temperatura, condición lumínica y potencial hídrico. Estas condiciones cambian notoriamente a mayores altitudes, pudiendo promover diferenciación en la respuesta fotoblás...
