Abstract80 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… 

Ecological aspects of plant colonisation of the Krakatau Islands

The varied data discussed in the paper indicates that with the exception of the strand-line, no component of the Krakatau flora or vegetation has yet approached a stable composition.

The role of animals in the colonization of the Krakatau Islands by fig trees (Ficus species)

The colonization of Anak Krakatau by Ficus species, agaonid wasps and volant frugivores over a critical decade (1982-92) is reviewed, including preliminary assessments of the effects of pollinator limitation on four pioneer fig species and indications of a possible effect of the presence of avian raptors, particularly the peregrine falcon, on fig colonization and forest diversification.

The birds of Anak Krakatau: the assembly of an avian community

The avian colonization of Anak Krakatau, an emergent volcanic island, is described for the period 1952–1991 with emphasis on the resident land birds. The few species that had colonized the island by

Plant colonization, succession and ecosystem development on Surtsey with reference to neighbouring islands

It is revealed that seabirds, through their transfer of nutrients from sea to land, are major drivers of develop- ment of these ecosystems and in the area impacted by seagulls, dense grassland swards have developed and plant cover, species richness, diversity, plant biomass and soil carbon are significantly higher than in low-impact areas, which re- mained relatively barren.

Anak Krakatau's vegetation and flora circa 1991, with observations on a decade of development and change

Ecological surveys were conducted over the period 1989 to 1991 on the island of Anak Krakatau. The aims of the study were to detail a key phase of rapid change in the vegetation succession and plant

Early successional communities on islands may include specialised aeolian-based pioneer arthropods scavenging on aerial fallout on volcanic lava or ash. Some such species appear to be restricted to

Ecology and conservation of bat species in the Western Ghats of India

Examination of the response of bats to coffee and tea plantations, and to riparian habitats, in the southern Western Ghats shows that combining catching and acoustic data gave the most complete picture of the assemblage, but that acoustic data alone detected more species than catching data alone.

Passive dispersal in arachnids

Some arachnids (spiders, mites and pseudoscorpions) are able to use both active and passive dispersal. The best-known passive dispersal method in arachnids is called eballooningi and starts with

Anak Krakatau — a colonization model within a colonization model?

AbstractThe ppaer re-examines three suggestions previously made concerning the colonization of the Krakatau islands since the extirpating 1883 eruption that involve the more recently emergent

Legacy or colonization? Posteruption establishment of peregrine falcons (Falco peregrinus) on a volcanically active subarctic island

It is hypothesized that the rapid reestablishment of peregrine falcons on Kasatochi was likely facilitated by behavioral characteristics of p PeregrineFalcons breeding in the Aleutian Islands, such as year‐round residency and breeding site fidelity, the presence of an abundant food source (seabirds), and limited vegetation requirements by seabirds and falcons.



Bird colonization of Anak Krakatau, an emergent volcanic island

Bird colonization of Anak Krakatau in the 1980s serves as a model for the early colonization processes that occurred on the archipelago in the first two decades of this century, including those species denied open habitats by plant succession.

Colonization of the Krakatau Islands by Animals: A Perspective from the 1980s

An examination of cases of turnover in animal species on the Krakataus since 1883, particularly vertebrates, supports the findings of plant ecologists that very little, if any, turnover is stochastic, and offers an analogy with the early decades of colonization after 1883.

Krakatau : colonization patterns and hierarchies

The Islands of Krakatau, Indonesia, provide a study site where a 106-year history of primary colonization leading to the establishment of lowland tropical forest can be documented and simple notions of equilibria are shown to be inadequate in such complex ecosystems.

Krakatau invertebrates: The 1980s fauna in the context of a century of recolonization

Invertebrate groups are at differing stages on the route towards an equilibrium number of species, and ecological changes involved in equilibration of the fauna as a whole should be the subject of future studies.

Colonization of the Krakatau Islands by Land Birds, and the Approach to an Equilibrium Number of Species

Analysis of the colonization data suggests that the first resident land birds colonized the Krakataus one or two decades after the 1883 eruption, and Anak Krakatau provides an ecological refuge, postponing the extinction of birds that depend on these open habitats.

Biogeography of mammals in SE Asia: estimates of rates of colonization, extinction and speciation

It is suggested that insular mammalian faunas typically are not in equilibrium, brrause geological and climatic changes can occur as rapidly as colonization and speciation, and any model of island biogeography to be widely applicable to insular faunaas must include speciation as a major variable.

Recolonization of the Krakatau Islands and adjacent areas of West Java, Indonesia, by bats (Chiroptera) 1883-1986

Since the cataclysmic eruption of 1883, 25 species of bats, of which 11 are pteropodids, have recolonized the Krakatau Islands and adjacent areas of West Java, Indonesia. Sixteen have been recorded

The colonization of the Krakatau Islands by fig wasps and other chalcids (Hymenoptera, Chalcidoidea)

Comparisons between chalcids collected by similar methods on the Krakatau Islands and in tropical West Africa indicated that at the family level the faunas are remarkably similar.

The Land Molluscs of the Krakatau Islands, Indonesia

The land molluscs collected on the 1984-85 Zoological Expeditions to the Krakatau Islands are reported on, and a synopsis provided of all previous land mollusc records since the 1883 eruption. The

The butterfly fauna of the Krakatau Islands after a century of colonization

Twenty species new to the Krakatau Islands and many new records to particular islands imply that the butterfly fauna is far from equilibrium, and conservation measures are suggested.
