Invasive alien palm Pinanga coronata threatens native tree ferns in an oceanic island rainforest

The invasive alien leaf miner Cameraria ohridella and the native tree Acer pseudoplatanus: a fatal attraction?

1 The horse-chestnut leaf miner Cameraria ohridella is an invasive moth in Europe and a serious pest of horse-chestnut Aesculus hippocastanum. The moth also occasionally attacks sycamore maple Acer pseudoplatanus, when situated beside infested horse-chestnuts. 2 The main objective of the present study was to provide an overview of the relationship between C. ohridella and A. pseudoplatanus and ...

The Role of Native Ecosystems in Constraining Alien Tree Invasions

Alien tree invasions cause widespread impacts to ecosystem structure and function in many regions across the globe. Limiting the spread of these invasions into untransformed native ecosystems is often a management priority. Understanding the mechanisms by which these native ecosystems are able to resist tree invasion can not only enhance our understanding of invasion processes but may also aid ...

Oeceoclades maculata, an alien tropical orchid in a Caribbean rainforest.

BACKGROUND AND AIMS Undisturbed forest habitat can be relatively impenetrable to invasive, non-native species. Orchids are not commonly regarded as invasive, but some species have become invasive and these generally depend on habitat disturbance. One of the most aggressive orchids is Oeceoclades maculata, a terrestrial species with remarkable ecological amplitude. Originally from tropical Afric...

Honeybees and Pollen as Indicators of Alien Plant Species in Two Native Forest Ecosystems of an Oceanic Island (La Palma, Canary Islands)

Apis mellifera L. is a generalist pollinator present in most of the Canary Islands. When foraging, honeybees transfer pollen grains to honey, and presence and abundance of pollen from different species can be interpreted as a sign of local flora, and a cue to spread of aliens. The relative use of alien vs native species by honeybees could influence island pollination mutualisms and/or favour al...
