Assessing Biodiversity Declines Understanding human impact on biodiversity depends sound quantitative projection. Pereira et al. (p. 1496 , published online 26 October) review scenarios that have been developed for four main areas of concern: species extinctions, abundances and community structure, habitat loss degradation, shifts in the distribution biomes. are projected whole 21st century all scenarios, but with a wide range variation. Hoffmann 1503 draw results five decades' worth data...
Abstract: Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis , is an emerging infectious disease implicated in declines of amphibian populations around globe. An one that has recently been discovered; increased incidence, geography, or host range; newly evolved. For any given outbreak disease, it therefore possible to state two hypotheses regarding its origin. The novel hypothesis states spread into new geographic areas, whereas endemic suggests present...
Abstract The chytrid fungus Batrachochytrium dendrobatidis has been implicated as the causative agent of mass mortalities, population declines and extinctions amphibian species worldwide. Although several studies have shown that prevalence chytridiomycosis (the disease caused by fungus) increases in cooler months, magnitude timing these seasonal fluctuations yet to be accurately quantified. We conducted sampling a single stony creek frogs Litoria wilcoxii on 13 occasions over 21‐month period...
ABSTRACT The chytrid fungus Batrachochytrium dendrobatidis has been implicated as the causative agent of mass mortalities, population declines, and extinctions stream‐breeding amphibian species worldwide. While factors that limit distribution abundance B. across large geographical regions are fairly well understood, little is known about within localized areas such individual catchments. accurate identification populations likely to be exposed urgently required for effective disease...
Chytridiomycosis is a recently emerged, infectious skin disease of amphibians that has been linked directly to mass mortalities, population declines, and species extinctions worldwide. An understanding the factors limit distribution abundance Batrachochytrium dendrobatidis (the etiological agent chytridiomycosis) urgently required. We conducted surveys at 31 lowland sites distributed north-south along 2315 km Australian east coast encompassed 20.8 degrees latitude. A total 863 adult male...
Summary 1. Altered global climates in the 21st century pose serious threats for biological systems and practical actions are needed to mount a response species at risk. 2. We identify management from across world diverse disciplines that applicable minimizing loss of amphibian biodiversity under climate change. Actions were grouped three thematic areas intervention: (i) installation microclimate microhabitat refuges; (ii) enhancement restoration breeding sites; (iii) manipulation hydroperiod...
Amphibians, like other animals, generate corticosterone or cortisol glucocorticoid responses to stimuli perceived be threatening. It is generally assumed that the response of animals capture and handling reflects such as sight a predator are thought natural stressors. Fijian ground frogs (Platymantis vitiana) preyed upon by introduced cane toads (Rhinella marina), we used test hypothesis will induce stress in an amphibian. Urinary metabolite concentrations increased male exposed toad for 1,...
Abstract The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding global decomposition patterns the drivers such are hampered by lack coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide found an overall negative correlation between initial mass‐loss rates stabilization factors plant‐derived carbon, using Tea Bag Index (TBI). factor quantifies degree to which easy‐to‐degrade components accumulate during...
Rainforest frogs are classified into nine ecological guilds based on features of reproduction, habitat use, temporal activity, microhabitat and body size. The largest differences between the microhylid rest frog species. Within non-microhylids, there two primary groups consisting (i) regionally endemic rainforest specialists, (ii) a more ecologically diverse group species that less specialized in their requirements. Most which includes three guilds, have declined or gone missing recent...
Abstract Catastrophic declines of amphibian populations have been reported from upland areas around the world, yet within regions not all species affected. Herein, we examine relationships between conservation status and ecological traits for over 60 eastern Australia. Among 24 phylogenetic groups examined, eight contained only declining species, both non‐declining had no suggesting are influenced by their evolutionary history. Declines one ( Philoria frosti ) 20 (i.e. genera Assa,...
Abstract: Global climate warming is expected to cause systematic shifts in the distribution of species and consequently increase extinction risk. Conservation managers must be able detect, measure accurately predict range order mitigate impacts on biodiversity. However, important responses change may go unnoticed or dismissed if we fail collect sufficient baseline data apply most sensitive analytical tests. Here use randomizations a contemporary set rainforest birds north‐eastern Australia...
The disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has dramatic amphibian population declines and extinctions in Australia, Central North America, Europe. Bd is associated with >200 species of amphibians, but not all that become infected are susceptible to disease. Specifically, rapidly emerged some areas world, such as USA, throughout South causing collapse. mechanism behind rapid global emergence poorly understood, part due an incomplete picture...

Abstract Global climates are changing rapidly and biological responses becoming increasingly apparent. Here, we use empirical abundance patterns across an altitudinal gradient predicted range shifts to estimate change in total population size relative distribution area response climate warming. Adopting this approach predict that, for nine out of 12 species regionally endemic birds, will decline more than with increasing temperature. Two showed comparable loss one exhibited a slower area....
