Biotic interactions and plant invasions.
TLDR
It is concluded that species introductions generally alter plants' interactions with enemies, mutualists and competitors, and that there is increasing evidence that these altered interactions jointly influence the success of introduced populations. Expand
Introduced species and their missing parasites
TLDR
The number of parasite species found in native populations is twice that found in exotic populations, and introduced populations are less heavily parasitized than are native populations. Expand
Ecosystem energetic implications of parasite and free-living biomass in three estuaries
TLDR
It is shown that parasites have substantial biomass in these ecosystems and that the annual production of free-swimming trematode transmission stages was greater than the combined biomass of all quantified parasites and was also greater than bird biomass. Expand
Parasites, pathogens, and invasions by plants and animals
TLDR
In conjunction with other biological and physical factors, release from parasites helps explain the increased demographic performance of invasive species, potentially accounting for much of the damage they cause. Expand
Release from Parasites as Natural Enemies: Increased Performance of a Globally Introduced Marine Crab
TLDR
A global assessment of the effect of parasitism and predation on the ecological performance of European green crab populations found that introduced species suffer less from parasites compared to populations where they are native. Expand
Direct and interactive effects of enemies and mutualists on plant performance: a meta-analysis.
TLDR
A meta-analysis of experiments in which two enemies, two mutualists, or an enemy and a mutualist were manipulated factorially found that the magnitude of (negative) enemy effects was greater than that of (positive) mutualist effects in isolation, but in the presence of other species, the two effects were of comparable magnitude. Expand
Effects of vulture declines on facultative scavengers and potential implications for mammalian disease transmission.
TLDR
The role of vultures in carcass decomposition and level of contact among mammalian scavengers is highlighted, leading to hypothesize that changes in vulture abundance may affect patterns of disease transmission among mammalian carnivores. Expand
Indirect effects of parasites in invasions
TLDR
The indirect effects of parasitic infection are important at a range of biological scales from within a host to the whole ecosystem in determining invasion success and impact, and requires an interdisciplinary approach by ecologists and parasitologists across animal and plant systems. Expand
Is the Collapse of Mud Shrimp (Upogebia pugettensis) Populations Along the Pacific Coast of North America Caused by Outbreaks of a Previously Unknown Bopyrid Isopod Parasite (Orthione griffenis)?
A dramatic increase in prevalence of the recently discovered bopyrid isopod parasite, Orthione griffenis, likely introduced in the 1980s from Asia to the Pacific coast of North America, coincidedExpand
Molecular phylogenetics reveals differential divergence of coastal snails separated by the Isthmus of Panama.
TLDR
Mangrove dwelling species were probably the last to be separated by the final closure of the Central American Seaway, and thus their divergence times correspond most accurately to the completion of the Isthmus. Expand
