A photo of a small dark black fly with an orange head and black eyes.

There's a new fly in town.

While out for a run yesterday, in Ōtautahi-Christchurch, NZ, I noticed this unusual orange-headed black fly. I uploaded my photos to #iNaturalist when I got home and learned that it's the Australian Soldier Fly, *Inopus rubriceps* […]

#Invasionbiology understands that you can predict that moving species around the globe will lead to mayhem at some future point. It also understands we cannot predict the where, when, who and how. Pretending to have the capacity to predict ecology, now or in the future, is disingenuous.

We shows that two introduced populations occupy different ecological niches, structuring genetic variation and limiting spread. 🧬

Job offer: PostDoc in “Invasion Biology, Spectroscopy, Chemical Ecology” 80-100% (f/m/d) You will join the FORSAID initiative which is seeking to establish a novel and comprehensive paradigm for identifying, observing and containing pest proliferations across Europe. As part of FORSAID, your research will focus on the invasive emerald ash borer (Agrilus planipennis, EAB) which has killed millions of ash trees outside its native range over the past 20 years. Given the advancing threat of the EAB in central Europe, it is crucial to implement effective screening and diagnostic methods. These methods are essential for two main purposes: the early detection of the beetle in European ash populations and the identification of ash trees with increased resistance to the pest. You will use controlled infestation experiments in biosafety greenhouses in combination with some field work to: (i) monitor the leaf spectral and metabolomic responses of ash trees attacked by EAB, (ii) use these response signals to distinguish EAB-induced stress from drought-related symptoms, and (iii) identify tree genotypes with enhanced resistance to EAB. You hold a PhD degree in Biology or Environmental Sciences and have a strong background in multivariate statistical analyses, chemical ecology, plant-herbivore interactions and experimental planning. Furthermore, we expect good knowledge in R programming, a good command of English, as well as strong skills in scientific paper writing. FORSAID encourages close collaborations among different European research groups. As such it is essential that you enjoy interacting with scientists of an interdisciplinary team and presenting your data to an international audience.

Figure illustrating 19 types of ecological impacts caused by invasive species, categorized across six levels of ecological organization: individual, population, species, assemblage, ecosystem function/service, and abiotic environment. The levels are shown as a series of six downward arrows, each representing a broader ecological scale. Each impact type is numbered, labeled, and illustrated with an icon, positioned according to the level it primarily affects. Arrows indicate how impacts can accumulate and cascade from one level to another, showing the interconnected and multi-scalar nature of biological invasion impacts.

We know invasive species cause several ecological impacts—but what kinds, exactly? 🌿⚠️🧪
Our latest paper breaks down the different types of impacts, from individuals to entire ecosystems. #Ecology #InvasionBiology

💡 This formulation follows the basic form ‘subject – relationship – object’, enhancing clarity & computational applications in #invasionbiology.

Hi folks,

I joined a couple of days ago.

I study #invasivespecies in freshwater ecosystems. My favorite model organisms are fish, mussels & crayfish. My students & I are keen to develop #invasionbiology theory to understand the impacts of introduced non-native animals on biodiversity & food webs.

How can #eDNA methods be applied to problems of terrestrial #biosecurity & #InvasionBiology? Our new review in #SciTotEnv looks into how this promising tool is being applied, its future potential & what needs to be done to close priority #KnowledgeGaps.

Do Aquatic Macrophytes Limit the Invasion Potential of Exotic Species in Pantanal Grasslands? - Wetlands Natural disturbances have the potential to limit exotic species invasions. The exotic grass, Urochloa humidicola, has high propagation potential following seasonal flooding, but, flooding tends to reduce the cover. Neither the potential for U. humidicola form a seed bank for recruitment following seasonal flooding, nor the mechanism responsible for reducing adult plant cover during floods is currently known. The soil seed bank of a U. humidicola was sampled for 2 years. To examine the potential role of competition with aquatic macrophytes in reducing its cover during floods, cuttings of U. humidicola were flooded in tanks in presence and absence of aquatic macrophytes for 3 months. Seedling density of U. humidicola was higher post-flood (245 seedlings/m−2) than the post-dry (130 seedlings/m−2). Germination occurred throughout the year, with highest seedling densities at the five to 7 months following soil collection. Competition with aquatic plants significantly increased mortality (c. 70%) of inundated U. humidicola. Our findings suggest that the survival potential of U. humidicola under flood is high, but is limited by shading of aquatic macrophytes. Nonetheless, its seed bank germinates throughout the year, though delayed by flooding. Control of invasive species in grasslands of the Pantanal depend on natural hydrological and biological drives.
