The impacts of biological invasions
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

The relationship between the feather tuft of the uropygial gland and terrestrial/aquatic birds [PDF]
The bird´s uropygial gland has a papilla in its caudal end and it can also show a feather tuft. These feathers may have a raquis or not. The purpose of our study was to compare the number, dimensions and types of the tuft´s feathers in aquatic and ...

How much biotic nativeness matters across human demographic groups
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Biology of Invasive Monk Parakeets in South Florida
Abstract Monk Parakeets (Myiopsitta monachus) have been in Florida for >40 yrs, having been imported by the thousands for the pet trade. This conspicuous, charismatic species is now widely established, but relatively little is known about its population biology outside South America.

Vertebrates...and the conflicts in public image [PDF]
The author explores human perceptions, as influenced by words and the images they conjure in the human brain. People worldwide have formed strong images relating to our environment, both positive and negative: beauty and splendor vs.

Combining trade data and niche modelling improves predictions of the origin and distribution of non-native European populations of a globally invasive species [PDF]
Aim: Although propagule pressure and environmental constraints are among the most important factors determining invasion success, studies considering both factors simultaneously are scarce.

Variable social organization and breeding system of a social parrot revealed by genetic analysis
Social organization and contributions to reproduction vary widely within and between species that breed in groups. Such variation often arises from the process of group formation, which drives patterns of relatedness and hence the degree of social conflict and co‐operation between group members.

The Number and Distribution of Introduced and Naturalized Parrots
Parrots have been transported and traded by humans for at least the last 2000 years and this trade continues unabated today. This transport of species has involved the majority of recognized parrot species (300+ of 382 species).

ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...
