Abstract:
Background and aims – North Saharan Acacia woodland is a fragile ecosystem altered by desertification and human activities. Little research has been conducted on the ecology of North Saharan Acacia woodland species. Seed size is a key trait to determine germination success, survival rate and establishment of Acacia woodland species under desert constraints.Methods – We analysed seed-size relationships in 42 selected woody plants in four different types of Acacia woodland vegetation which correspond to 26 plant species. We examined the correlation among seed size, fruit size, plant height, leaf

Abstract:
AbstractThe island fox (Urocyon littoralis) is one of few reportedly endemic terrestrial mammals on California's Channel Islands. Questions remain about how and when foxes first colonized the islands, with researchers speculating on a natural, human-assisted, or combined dispersal during the late Pleistocene and/or Holocene. A natural dispersal of foxes to the northern Channel Islands has been supported by reports of a few fox bones from late Pleistocene paleontological localities. Direct AMS 14C dating of these “fossil” fox bones produced dates ranging from ∼ 6400 to 200 cal yr BP, however, p

AbstractThe non-native midge Eretmoptera murphyi is Antarctica’s most persistent non-native insect and is known to impact the terrestrial ecosystems. It inhabits by considerably increasing litter turnover and availability of soil nutrients. The midge was introduced to Signy Island, South Orkney Islands, from its native South Georgia, and routes of dispersal to date have been aided by human activities, with little known about non-human-assisted methods of dispersal. This study is the first to determine the potential for dispersal of a terrestrial invertebrate species in Antarctica by combining

Abstract:
80 species of non-marine, non-migrant vertebrates, excluding also shore birds, have been recorded from the Krakatau archipelago since the explosive eruption of 1883.73 of these are believed to have established breeding populations and successfully colonized the islands (47 resident land birds species, 13 bats, 11 reptiles and 2 rats). A large proportion of these colonizers consists of species with wide distributions, broad ecological tolerances and/or association with urban or rural situations. 11 of the 73 colonizing species (8 resident land birds, 2 reptiles and a bat) have become extinct on

Abstract:
We argue that human-mediated invasions are part of the spectrum of species movements, not a unique phenomenon, because species self-dispersing into novel environments are subject to the same barriers of survival, reproduction, dispersal and further range expansion as those assisted by people. Species changing their distributions by human-mediated and non-human mediated modes should be of identical scientific interest to invasion ecology and ecology. Distinctions between human-mediated invasions and natural colonisations are very valid for management and policy, but we argue that these are valu

Abstract:
The value of distinguishing between plant species regarded as ‘native’ and ‘alien’ has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction between a ‘native’ and ‘naturalised’ flora and is applied for the entire Australian flora of vascular plants. Herbarium collections and ecological criteria were employed to determine the status of 168 species of ambiguous origin. The date of 1788 proved to be a relatively straightforward criterion to

Dams, utilized for hydroelectric or flood control purposes, obstruct organism dispersal and have contributed to the decline of many migratory fish populations. For threatened Chinook salmon (Oncorhynchus tshawytscha) from the Willamette River Basin in Oregon, human-assisted reintroductions are being used to facilitate dispersal to historical habitats located above dams. However, little is known about the reproductive outcomes of reintroduced individuals or the efficacy of reintroductions towards the goal of population demographic viability.

Abstract In the twenty-first century, the warming climate poses major threats to forest ecosystems. Assisted migration has emerged as a proactive adaptation and conservation strategy to mitigate the impacts of climate change and safeguard biodiversity. This approach comprises the human-assisted movement and dispersal of species and populations to areas predicted to be suitable under future climate conditions. Assisted migration is the subject of much debate in the scientific literature. While it offers potential benefits in terms of promoting biodiversity, sustaining forest productivity, and c

Abstract:
This chapter studies the causes and consequences of invasive alien species (IAS), as well as the methods to manage and mitigate their impacts. A native species (or indigenous species) is one that occurs within its natural range (past or present) and that does so in the absence of dispersal that is assisted, either directly or indirectly, by humans. In contrast, an alien species (also called exotic, foreign, introduced, nonindigenous, or non-native species) is one that occurs outside of its natural range (past or present) and beyond its natural dispersal abilities, assisted in some way by human
