Introduced galliforms as seed predators and dispersers in Hawaiian forests

In altered communities, novel species’ interactions may critically impact ecosystem functioning. One key ecosystem process, seed dispersal, often requires mutualistic interactions between frugivores

Combined effects of bird extinctions and introductions in oceanic islands: decreased functional diversity despite increased species richness

Aim We analyse the functional consequences of the changes in species composition resulting from extinctions and introductions on oceanic island bird assemblages. Specifically, we ask if introduced

Threatened and extinct island endemic birds of the world: Distribution, threats and functional diversity

The world's islands support disproportionate levels of endemic avian biodiversity despite suffering numerous extinctions. While intensive recent research has focused on island bird conservation or

Frugivore distributions are associated with plant dispersal syndrome diversity in the Caribbean archipelagos

Many plants rely on interactions with frugivores for dispersal, suggesting that animal communities may affect plant occupancy and diversity. However, the contribution of these interaction‐led biotic

Conservation paleobiology on Minami-Daito Island, Okinawa, Japan: anthropogenic extinction of cave-dwelling bats on a tropical oceanic island

Background With strong environmental and geographic filtration, vertebrates incapable of flying and swimming are often extirpated from island ecosystems. Minami-Daito Island is an oceanic island in

Scientists’ warning – The outstanding biodiversity of islands is in peril

Hawai‘i Forest Review: Synthesizing the Ecology, Evolution, and Conservation of a Model System

A roadmap to plant functional island biogeography

This work has shown that species traits can potentially offer new biological insights into the processes by which island life assembles and why some species perform better at colonising and persisting on islands.



Seed size predicts global effects of small mammal seed predation on plant recruitment.

It is suggested that seed size may serve as a key life-history trait that can integrate consumer effects to improve understandings of plant coexistence.

Collapse of dispersal trait diversity across a long‐term chronosequence reveals a strong negative impact of frugivore extinctions on forest resilience

Understanding how seed dispersal disruption may alter plant community diversity and dynamics over a large temporal scale remains a challenge. Here, we use a long‐term chronosequence to compare

The diets of moa (Aves: Dinornithiformes)

A synthesis of current knowledge about moa diets is provided, including summarising 2755 records of plant remains from 23 moa gizzard contents and 158 moa coprolites, to identify specific ecological functions and roles that have been lost due to the extinction of moa, and resolve to what extent these could be replaced via surrogate taxa.

Rodent detection and monitoring for conservation on islands: gnawed seeds provide reliable indicator of rodent presence

It is suggested that gnawed seeds can complement other rodent detection devices to increase the probability of detection and could be used to detect rodent presence on other island groups globally, e.g. using opened coconuts in the field as a kind of natural waxtag or ‘cocotag’.

Seed dispersal effectiveness by a large‐bodied invasive species in defaunated landscapes

Animal‐dispersed plants are increasingly reliant on effective seed dispersal provided by small‐bodied frugivores in defaunated habitats. In the Neotropical region, the non‐native wild pig (Sus

The ecology and evolution of seed predation by Darwin's finches onTribulus cistoideson the Galápagos Islands

Results suggest that Darwin's finches and T. cistoides are experiencing an ongoing coevolutionary arms race, and that the strength of this coev evolution varies in space and time.

Global Biodiversity

A highly resolved food web for insect seed predators in a species‐rich tropical forest

The first food web quantifying trophic interactions between the majority of co‐occurring woody plant species and their internally feeding insect seed predators suggests that seed predators are unlikely to mediate indirect interactions such as apparent competition between plant species, but are consistent with their proposed contribution to maintaining plant diversity via the Janzen–Connell mechanism.

Non-native Mammals Are the Main Seed Dispersers of the Ancient Mediterranean Palm Chamaerops humilis L. in the Balearic Islands: Rescuers of a Lost Seed Dispersal Service?

It is concluded that goats and pine martens are effective seed dispersers of C. humilis in this and probably other Mediterranean islands, where humans led to the extinction of its native seed disperser, as it was probably the case of the goat-like Myotragus balearicus in the Balearic Islands.
