Invasive Carcinoma

, 2017
This chapter illustrates the main form of breast cancer setting the basis of the diagnosis of malignancy on FNAC and providing some hints to direct cytological interpretation towards one or the other specific type of ...

Distribution of Asian knotweeds on the Rhône River basin, France: A multi-scale model of invasibility that combines biophysical and anthropogenic factors.

Science of the Total Environment, 2020
Biotic and abiotic factors are important drivers of the introduction, dispersal and establishment of an invasive species in fluvial corridors. In this study, we propose to better understand the spatial distribution of Asian knotweeds and to model their ...

Litter nutrient release and allelopathy jointly contribute to the diversity–invasibility relationship

Functional Ecology, Volume 39, Issue 12, Page 3446-3458, December 2025.
Abstract Elton's biotic resistance hypothesis suggests that diverse communities are more resistant to biological invasions. While below‐ground mechanisms play a crucial role in regulating the diversity–invasibility relationship, the role of litter as a key regulator of below‐ground processes remains underexplored. We used 15 common native plant species

Effects of initial disturbances and grazing regime on native grassland invasion by Eragrostis plana in southern Brazil

Perspectives in Ecology and Conservation, 2018
Extensive invasion of the Campos grasslands of southern Brazil by the South African grass, Eragrostis plana, is a serious conservation problem due to its low palatability and ability to quickly spread.

Density Dependence Promotes Species Coexistence and Provides a Unifying Explanation for Distinct Productivity–Diversity Relationships

Ecology Letters, Volume 28, Issue 12, December 2025.
We develop a mechanistic framework to understand how negative density dependence shapes diversity in complex communities. By modelling resource consumption and species interactions, we show that density‐dependent mortality expands coexistence zones and explains variable productivity–diversity relationships. A derived formula predicts species abundances

Evaluating Hypotheses of Plant Species Invasions on Mediterranean Islands: Inverse Patterns between Alien and Endemic Species

Frontiers in Ecology and Evolution, 2017
Invasive alien species cause major changes to ecosystem functioning and patterns of biodiversity, and the main factors involved in invasion success remain contested.

Plant-soil feedbacks promote coexistence and resilience in multi-species communities.

PLoS ONE, 2019
Both ecological theory and empirical evidence suggest that negative frequency dependent feedbacks structure plant communities, but integration of these findings has been limited.

Understanding trade pathways to target biosecurity surveillance

NeoBiota, 2013
Increasing trends in global trade make it extremely difficult to prevent the entry of all potential invasive species (IS). Establishing early detection strategies thus becomes an important part of the continuum used to reduce the introduction of invasive

The ‘filtering’ metaphor revisited: competition and environment jointly structure invasibility and coexistence

bioRxiv, 2018
‘Filtering’, or the reduction in species diversity that occurs because not all species can persist in all locations, is thought to unfold hierarchically, at large scales due to the environment and at small scales due to competition.

Landscape, demographic, and dispersal parameters influence the spread and establishment of an aquatic biological invasion

Ecosphere
Human‐mediated species introductions are contributing to the biotic homogenization of global flora and fauna. Despite extensive research, we lack simple methods of predicting how and where an introduced species will spread and establish, particularly in ...
