Invasive mosquitofish become more aggressive in the presence of native pike young-of-year: implications for native predator recruitment
Published: 2025-10-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology
Invasive species often exhibit aggressive behaviour, boldness, and high foraging activity, which contribute to their establishment success and impact on native ecosystems. The mosquitofish (Gambusia holbrooki), one of the world’s most invasive fish species, is known for its aggressive nature, which threatens the survival of native species. Lake littoral zones, critical for juvenile fish [...]

The invasive Asian tiger mosquito (Aedes albopictus) has become an important public health concern in Italy, particularly in the Po Valley area, where its biting behaviour and nuisance have contributed to multiple outbreaks of mosquito-borne diseases over the last two decades. To address this growing threat, the Emilia-Romagna region has conducted intensive mosquito monitoring efforts since 2010, [...]
Species Invasion in a Two-Dimensional Space with Irregularly Shaped Patches
Published: 2025-09-24
Subjects: Ecology and Evolutionary Biology, Population Biology
Accounting for spatial heterogeneity in the evolution of a species population in a given space is of much importance in population ecology, epidemiology and related fields in biosciences. Past literature has presented such analysis in the presence of regions with distinct diffusion/growth properties, often referred to as patches. However, most of the past work is limited to one-dimensional space, [...]
Spatial networks of habitats, populations, and communities: connecting approaches to keep cutting edges
Published: 2025-09-23
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Purpose of review: Spatial networks are extensively used in ecology to represent exchanges among landscape features (e.g., habitat patches, river segments) or biological entities (e.g., individuals, populations, communities). I reviewed the literature produced in the past 25 years using these networks. Distinct types of spatial networks have emerged in several subfields of ecology. I aimed to [...]
Trends of ungulate species in Europe: not all stories are equal
Published: 2025-09-17
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology, Zoology
Wild ungulates have deep impacts on socio-ecological systems, and analyzing large-scale population trends in a multispecies set can identify their environmental and socio-economic drivers. We collected annual hunting bags (n = 11,046, period 1975-2018) of 7 wild ungulates of high management interest across 25 European countries. We identified different temporal trends in hunting bags and for roe [...]

Persefone.jl: Modelling Biodiversity in Dynamic Agricultural Landscapes
Published: 2025-08-31
Subjects: Agriculture, Behavior and Ethology, Biodiversity, Population Biology
Agricultural landscapes are highly dynamic, constantly changing in space and time due to the effects of farm management and environmental factors. To forecast the effects of changes in agricultural systems on biodiversity, we need to understand these landscape dynamics and how they impact different species. Here, we present Persefone.jl, an open-source process-based model of agricultural [...]

Predictive Evolutionary Genomics: Principles, Validation, and Practice
Published: 2025-08-11
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Evolution, Genomics, Life Sciences, Plant Sciences, Population Biology
Contemporary evolution occurs on observable timescales, enabling prospective evolutionary forecasting with quantitative frameworks rather than only retrospective inference. We propose a unified probabilistic framework that integrates three approaches linked to detectability windows through time. Trait-based models use multivariate quantitative-genetic equations to project correlated phenotypic [...]
