Formulating effective management plans for addressing the impacts of invasive non-native species (INNS) requires the definition of clear priorities and tangible targets, and the recognition of the plurality of societal values assigned to these species. These tasks require a multi-disciplinary approach and the involvement of stakeholders. Here, we d...
Article
The study of the genetic characteristics of invasive plant species in native and invaded ranges is an increasingly important attempt for understanding current patterns of invasive plants distribution. While Argentina holds a significant number of invasive woody plant species, scant research has been conducted to determine their invasion pathways. H...

ContextKnowing which factors determine the spread of plant invaders is a relevant issue in global ecology. Cultural landscapes both influence and are affected by exotic species. Although bioclimatic boundaries, seed sources and landscape configuration all control the invasion process, they have been mostly studied separately and independently from...
Article
Disturbances such as selective logging in a forest may lead to a degradation process, where new species become dominant and replace the original vegetation. This is the case of the Semi-deciduous Atlantic Forest, where bamboos replace trees and palms, affecting the forest structure and dynamics. As bamboos show plant traits that contrast those of t...
Article
Full-text available
Evolutionary processes greatly impact the outcomes of biological invasions. An extensive body of research suggests that invasive populations often undergo phenotypic and ecological divergence from their native sources. Evolution also operates at different and distinct stages during the invasion process. Thus, it is important to incorporate evolutio...

Abstract. Invasive plant species may benefit from a reduction in herbivory in their introduced range. The reduced herbivory may cause a reallocation of resources from defence to fitness. Here, we evaluated leaf herbivory of an invasive tree species (Ligustrum lucidum Aiton) in its native and novel ranges, and determined the potential changes in lea...

Physiological characteristics of saplings can be considered one of the most basic constraints on species distribution. The shade-tolerant arborescent palm Euterpe edulis Mart. is endemic to the Atlantic Forest of Argentina, Brazil and Paraguay. At a local scale, saplings of this species growing in native forests are absent in gaps. We tested the hy...
Article
Ligustrum lucidum is the major exotic tree in NW Argentina montane forests (Yungas). To assess the effects of its expanding invasion on avian communities we (1) measured different habitat properties (vertical forest structure and composition, vegetation cover, light availability, air temperature, air relative humidity and soil litter depth), (2) co...
Article
Invasions of exotic tree species can cause profound changes in community composition and structure, and may even cause legacy effect on nutrient cycling via litter production. In this study, we compared leaf litter decomposition of two invasive exotic trees (Ligustrum lucidum and Morus sp.) and two dominant native trees (Cinnamomum porphyria and Cu...
Article
Many woody bamboo species are forest understory plants that become invasive after disturbance. They can grow rapidly forming a dense, nearly monospecific understory that inhibits tree regeneration. The principal aim of this study was to understand what functional traits of bamboos allow them to outcompete tree seedlings and saplings and become succ...

In tropical and subtropical moist forests the most important factor limiting plant growth is solar radiation. On this basis, tree species had traditionally been classified into two functional groups based on their requirements for germination, establishment and growth. While shade-tolerant species germinate, grow and establish in places with low so...

Potential areas for nature conservation in the Tandilia System of Argentina (Pampas region) still persist in the agricultural-dominated landscape in small hills and outcrops (sierras and cerrilladas), streams, small lagoons and their buffer areas, and roadsides, among others. Many of these areas have been studied from different perspectives and dimensions under multiple objectives (i.e. biodiversity, ecosystem services, structure and function, roles, cultural value, etc.) and some of them are critical biodiversity hotspots and a source of germoplasms and ecosystem services. However, until now the efforts for their conservation and sustainable management are scarce, being represented in isolated cases (areas) and without an integrated planning. We hypothesized that the lack of successful conservation strategies in the system is due to a great disconnection between humans and nature, and among humans themselves. In other words, there is a lack of coordination and linkage between different social actors (i.e. governmental institutions, farmers, and academic researchers) on environmental matters, and between them and the ecological structure. Our main goal is to generate a conceptual model that includes ecological resources (non-cropped lands conservation status and connectivity), the management that farmers perform on them, scientific investigations, and governance objectives on conservation, along with an explicit representation on how all these entities are connected to each other.
Project
This ambitious, international project aims to preserve biodiversity, ecosystem services and livelihoods by improving the strategic, long-term management of damaging invasive non-native species (INNS) that cannot be eradicated and must be managed in perpetuity. The project levers existing high quality ecological data on animal and plant invasive species already acquired by LATAM project members, together with targeted new data collection (including from experimental control), and integrates this with state-of-the-art modelling approaches developed by the UK project members in order to deliver novel tools and approaches that can inform the effective management of INNS in the region.
