Large-scale impacts of multiple co-occurring invaders on monkey puzzle forest regeneration, native seed predators and their ecological interactions

Global Ecology and Conservation, 2016
Most ecosystems of the world are being increasingly invaded by a variety of alien species. However, little is known about the combined ecological impacts of multiple co-occurring invaders.

Sex and Age Effects on Monk Parakeet Home-Range Variation in the Urban Habitat

Diversity, 2021
Home-range size is a key aspect of space-use, and variation in home-range size and structure may have profound consequences for the potential impact of damage and control strategies for invasive species.

A Cross‐Sectional Study on Parakeets Feeding and Housing Practices in Italy

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Italy has one of the largest companion bird populations in Europe. This study aimed to investigate feeding and housing practices among Italian parakeet owners. An online questionnaire was distributed, yielding 433 voluntary responses. Participants were classified as hobbyists (HBY; ≤ 13 birds owned) or breeders (BRD; > 13 birds owned) to ...

The prevalence of psittacine circovirus in native and exotic parrots in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology at Massey University [PDF]

, 2005
Psittacine circovirus (PCV) has been identified in more than 60 psittacine species worldwide in both aviary and wild populations. The virus is a causative agent of psittacine circoviral disease (PCD), a highly infectious disease characterised by beak and

The spread of non‐native species

Biological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Estimating the population size of two critically endangered South Pacific parakeets : the Tasman Parakeet and Malherbe's Parakeet : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology, Massey University, New Zealand [PDF]

, 2018
The Cyanoramphus parakeets are a cryptically coloured group of birds that are distributed across the islands of the South Pacific region. Due to their restricted range and island distributions, species belonging to this genus are considered vulnerable to

Combining trade data and niche modelling improves predictions of the origin and distribution of non-native European populations of a globally invasive species [PDF]

, 2017
Aim: Although propagule pressure and environmental constraints are among the most important factors determining invasion success, studies considering both factors simultaneously are scarce.
