New Reports of Exotic and Native Ambrosia and Bark Beetle Species (Coleoptera: Curculionidae: Scolytinae) From Ohio [PDF]

open access: yes, 2018
In a 2007 survey of ambrosia and bark beetles (Coleoptera: Curculionidae: Scolytinae) along a transect in northeastern Ohio, we collected six exotic and three native species not previously reported from the state.

Are Local Filters Blind to Provenance? Ant Seed Predation Suppresses Exotic Plants More than Natives [PDF]

open access: yes, 2014
The question of whether species’ origins influence invasion outcomes has been a point of substantial debate in invasion ecology. Theoretically, colonization outcomes can be predicted based on how species’ traits interact with community filters, a process

Controlled ectomycorrhization of an exotic legume tree species Acacia holosericea affects the structure of root nodule bacteria community and their symbiotic effectiveness on Faidherbia albida, a native sahelian Acacia [PDF]

open access: yes, 2008
In the 400-700 mm rainfall zone, Acacia holosericea was found to be one of the best-adapted exotic tree showing excellent survival rate and rapid early growth (Harwood, 1994).

ECOLOGICAL RELEASE OF AN EXOTIC SPECIES UPON SUPPRESSION OF ITS INVASIVE PREDATOR: A FIVE-YEAR CASE STUDY, WITH NOTES ON OTHER SPECIES, AND THE LIFE HISTORY OF THE MEDITERRANEAN GECKO, HEMIDACTYLUS TURCICUS [PDF]

open access: yes, 2014
Ecological release allows a species to expand beyond its currently occupied niche upon removal of a limiting mechanism such as a predator or competitor. Unfortunately, these interactions between exotic and invasive organisms are relatively unknown.

Introduction of Alien Tree Species and its Influence on Floristical Composition and Vegetation Structure of Acidophilous Oak Forests: The Experimental Plots in the Zielonka Forest [PDF]

open access: yes, 2011
In 1879 Schwappach first established 54 experimental forest plots on habitat of acidophilous oak forest Calamagrostio-Quercetum in the Zielonka Forest near Poznań, on which 20 exotic tree species were cultivated. Until this day 32 of the mentioned forest

Exotic herbaceous species interact with severe drought to alter soil N cycling in a semi-arid shrubland [PDF]

open access: yes, 2020
Mediterranean-type ecosystems are increasingly threatened by climate change and exotic annual species, jeopardizing the native communities and their global biodiversity.

Preliminary checklist of the bees of St. Eustatius, Lesser Antilles (Hymenoptera: Apoidea: Anthophila) [PDF]

open access: yes, 2013
We present a preliminary checklist of bees (Hymenoptera: Apoidea: Anthophila) compiled for St. Eustatius, an island located in the Lesser Antilles of the eastern Caribbean. The list has nine species, including six that have not been previously documented

Comparative Biology of Temperate and Subtropical Bark and Ambrosia Beetles (Coleoptera: Scolytidae, Platypodidae) in Indiana and Florida [PDF]

open access: yes, 2017
Bark and ambrosia beetles were compared from two intensively studied sites. The Indiana site produced 58 species, the Florida site 57 species; 17 species occurred at both sites. Much greater plant host diversity at the Indiana site seems balanced by more

Restoring Balance: Using Exotic Species to Control Invasive Exotic Species [PDF]

open access: yesConservation Biology, 2004
Abstract:  Invasive species threaten natural habitats worldwide, and active human management is required to prevent invasion, contain spread, or remediate ecosystems following habitat degradation. One powerful technology for invasive species management in sensitive habitats is biological control, the use of ...
