The establishment success of a population is function abiotic and biotic factors introduction dynamics. Understanding how these interact has direct consequences for understanding managing biological invasions applied ecology more generally. Here we use mesocosm approach to explore the size founding populations number events with environmental conditions (temperature) determine laboratory-reared Drosophila melanogaster. We found that temperature played biggest role in success, eclipsing other experimental when viewed overall. Under optimal propagule pressure was negligible importance success. At adverse temperatures, however, increased total size. This effect considerably stronger at cold than hot extreme. Whether introduced all once or by increments (changing events) had global effect. However, again, increasing seen extremes revealing opposite effects: adding flies incrementally decreased their extreme, but it These differing effects thermal implies different mechanisms are play either results suggest effort required prevent (or conversely, facilitate) varies environment ways can be complicated predictable.

Abstract Since Baker’s attempt to characterize the ‘ideal weed’ over 50 years ago, ecologists have sought identify features of species that predict invasiveness. Several traits are well studied, and we now understand many can facilitate different components invasion process, such as dispersal promoting transport or selfing enabling establishment. However, effects on context dependent. The in one community at stage may inhibit other communities success stages, benefits any given trait depend possessed by species. Furthermore, variation among populations is result evolution. Accordingly, evolution both prior after determine outcomes. Here, review how our understanding ecology invasive plants has developed since original efforts, resulting from empirical studies emergence new frameworks ideas assembly theory, functional ecology, rapid adaptation. Looking forward, consider trait-based approaches might inform less-explored aspects biology ranging responses climate change coevolution invaded communities.

Abstract Novel environmental conditions experienced by introduced species can drive rapid evolution of diverse traits. In turn, evolution, both adaptive and non‐adaptive, influence population size, growth rate, other important ecological characteristics populations. addition, spatial evolutionary processes that arise from a combination assortative mating between highly dispersive individuals at the expanding edge populations altered reproductive rates those accelerate expansion speed. Growing experimental evidence shows effects on dynamics be quite large, thus it affect establishment, persistence, distribution We review theoretical literature such eco‐evolutionary feedbacks evaluate implications these for biological control. Experiments show evolving establish higher grow larger than non‐evolving However, non‐adaptive processes, as genetic drift inbreeding depression also lead to reduced fitness declines in size. Spatial increase spread change front. These examples demonstrate power indicate is likely more biocontrol programs previously realized. discuss how this knowledge used enhance efficacy

Why do infectious diseases erupt in some host populations and not others? This question has spawned independent fields of research evolution, ecology, public health, agriculture, conservation. In the search for environmental genetic factors that predict variation parasitism, one hypothesis stands out its generality longevity: genetically homogeneous are more likely to experience severe parasitism than diverse populations. this perspective piece, I draw on overlapping ideas from evolutionary biology, conservation capture far-reaching implications link between diversity disease. first summarize development results experimental tests. Given convincing support protective effect diversity, then address following questions: (1) Where idea been put use, a basic applied sense, how can we better use limit disease spread? (2) What new hypotheses does established disease-diversity relationship compel us test? conclude monitoring, preserving, augmenting is our most promising evolutionarily informed strategies buffering wild, domesticated, human against future outbreaks.

To successfully colonize new habitats, organisms not only need to gain access it, they also cope with the selective pressures imposed by local biotic and abiotic conditions. The number of immigrants, preadaptation habitat presence competitors are important factors determining success colonization. Here, using two experimental set‐ups, we studied effect interspecific competition in combination propagule pressure on colonization habitats. Our model system consisted tomato plants (the novel habitat), two‐spotted spider mite Tetranychus urticae as our focal species red evansi a competitor. results show that positively affect success. More successful populations reach larger final population sizes either having higher per capita growth rates (due effects) or starting individuals. Although more colonizing non‐competitive environments than competitive ones, counteract negative effects competition, promoting study shows importance for habitats providing ability both exigencies community context.

Abstract Successful biological invasions are dependent on the invader being able to grow and reproduce in new environment. One way that microbial invaders may facilitate this is use cooperative public goods, such as metal-binding siderophores. However, siderophore production can be exploited by non-producing cheats who benefit from without paying any associated costs. Here, we test importance of cooperation for success Pseudomonas aeruginosa invading a 5-species community. We do comparing siderophore-producing strain, siderophore-deficient mutant strain 50:50 mixed population, both environments with weak (copper absent) strong present) requirement. found no effect type when siderophores were less essential growth, but large differences they selectively favoured. Here producer-cheat mix had greatest success, strains having near equal fitness reaching high densities, whilst isolation producers intermediate lowest. Similarly, resident diversity only differed across treatments copper was present. In conclusion, show presence provide larger invasion than pure cooperator populations, goods particularly beneficial.

Abstract Dispersal is a key ecological process that strongly influenced by both phenotype and environment. Here, we show juvenile environment influences dispersal not only shaping individual phenotypes, but also changing the phenotypes of neighbouring conspecifics, which influence how individuals disperse. We used model system ( Tribolium castaneum , red flour beetles) to test past dispersing their neighbours they disperse in current found dispersed especially far when exposed poor as adults if phenotype, or even one‐third neighbours’ were shaped juveniles. Juvenile therefore shapes directly, influencing well indirectly, external social Thus, minority group can entire group.

Abstract Colonization is a critical filter, setting the stage for short‐term and long‐term population success. Increased propagule pressure (e.g., more founding individuals) usually enhances colonization; however, this pattern may be driven by purely numeric effects, genetic diversity or both. To determine independent interactive effects of diversity, we conducted seed addition experiment in field using ruderal annual Arabidopsis thaliana . Propagule treatments spanned five levels, from 32 to 960 seeds per 0.25‐m 2 plot. Founder populations were composed one, four, eight genotypes exposed ambient reduced levels interspecific competition. Genotype monocultures included quantify additive vs. non‐additive effects. Populations followed three generations, with abundance, persistence genotype retention (the proportion introduced persisting over time) as major response variables. enhanced abundance immediately following introduction, particularly where nutrient availability was high competition reduced. Greater also increased likelihood through generations. However, most experienced rapid declines time, yielding no relationship between third‐generation across populations. Under competition, led marginal increase third generation that pronounced, statistically significant, low conditions. Genetic did not affect first generation, thus indicating strengthened time. Nevertheless, genotypic mixture fell short expectations based on performance (negative effects). associated declines, largely due one high‐performing lowest (i.e., identity Overall, our results indicate increases both can enhance colonization success but are highly context dependent. They highlight novel ways which factors impact Our findings pinpoint determinants fundamental process have key implications applications suppressed desired, including ecological restoration invasive species management.
