Vector bionomics and vectorial capacity as emergent properties of mosquito behaviors and ecology

Sean Wu, Penny Hancock, Arnaud Le Menach, Tanya Russell, Thomas Burkot, , Derek Cummings, Kelly Compton, Daniel Citron, John Marshall, Biyonka Liang, Catherine Moyes, Qian Zhang, David Smith, Samson Kiware, Anne Wilson, Thomas Scott, John Henry, Steven Lindsay, Amit Verma & Hector Sanchez C.
Mosquitoes are important vectors for pathogens that infect humans and other vertebrate animals. Some aspects of adult mosquito behavior and mosquito ecology play an important role in determining the capacity of vector populations to transmit pathogens. Here, we re-examine factors affecting the transmission of pathogens by mosquitoes using a new approach. Unlike most previous models, this framework considers the behavioral states and state transitions of adult mosquitoes through a sequence of activity bouts. We developed...

Data from: Ocean acidification alters predator behaviour and reduces predation rate

Sue-Ann Watson, Jennifer B. Fields & Philip L. Munday
Ocean acidification poses a range of threats to marine invertebrates; however, the emerging and likely widespread effects of rising carbon dioxide (CO2) levels on marine invertebrate behaviour are still little understood. Here, we show that ocean acidification alters and impairs key ecological behaviours of the predatory cone snail Conus marmoreus. Projected near-future seawater CO2 levels (975 µatm) increased activity in this coral reef molluscivore more than threefold (from less than 4 to more than 12...

Data from: Community-wide scan identifies fish species associated with coral reef services across the Indo-Pacific

Eva Maire, Sébastien Villéger, Nicholas A.J. Graham, Andrew S. Hoey, Joshua Cinner, Sebastian C.A. Ferse, Catherine Aliaume, David J. Booth, David A. Feary, Michel Kulbicki, Stuart A. Sandin, Laurent Vigliola, David Mouillot & Sebastian C. A. Ferse
Determining whether many functionally complementary species or only a subset of key species are necessary to maintain ecosystem functioning and services is a critical question in community ecology and biodiversity conservation. Identifying such key species remains challenging, especially in the tropics where many species co-occur and can potentially support the same or different processes. Here, we developed a new community-wide scan (CWS) approach, analogous to the genome-wide scan, to identify fish species that significantly contribute,...

Data from: Genetic and paleomodelling evidence of the population expansion of the cattle egret Bubulcus ibis in Africa during the climatic oscillations of the Late Pleistocene

Carlos Congrains, Antônio F. Carvalho, , Graeme S. Cumming, Dominic A. W. Henry, Shiiwua A. Manu, Jacinta Abalaka, Cristiano D. Rocha, Moussa S. Diop, Joãozinho Sá, Hamilton Monteiro, Lars H. Holbech, Francis Gbogbo & Silvia N. Del Lama
Increasing aridity during glacial periods produced the retraction of forests and the expansion of arid and semi-arid environments in Africa, with consequences for birds. Cattle egret (Bubulcus ibis) is a dispersive species that prefers semiarid environments and requires proximity to bodies of water. We expected that climatic oscillations led to the expansion of the range of the cattle egret during arid periods, such as the Last Maximum Glacial (LGM) and contraction of distribution during the...

Data from: Blue Carbon stocks of Great Barrier Reef deep-water seagrasses

Paul York, Peter I. Macreadie & Michael A. Rasheed
Shallow-water seagrasses capture and store globally-significant quantities of organic carbon (OC), often referred to as ‘Blue Carbon’; however, data is lacking on the importance of deep-water (>15 m) seagrasses as Blue Carbon sinks. We compared OC stocks from deep-, mid- and shallow-water seagrasses at Lizard Island within the Great Barrier Reef Lagoon. We found deep-water seagrasses (Halophila species) contained similar levels of OC as shallow-water species (e.g Halodule uninervis) (0.64 ± 0.08% and 0.9 ±...

Data from: Latitudinal and seasonal variation in space use by a large, predatory reef fish, Plectropomus leopardus

Molly E. Scott, Michelle R. Heupel, Colin A. Simpfendorfer, Jordan K. Matley & Morgan S. Pratchett
1. Temperature directly affects the metabolic rate and resource requirements of ectothermic animals, which is likely to influence their movement and habitat use. Space use is a fundamental component of an animal’s ecology and the extent of an animal’s home range has consequences for individual distributions, community structure and ecosystem function. As ocean temperatures continue to rise as a result of global warming, determining the effects of temperature on space use and movement patterns of...

Data from: Australian house geckos are more aggressive than a globally successful invasive Asian house gecko

Adam Cisterne, Lin Schwarzkopf & David A. Pike
Invasive species are implicated in native species declines globally, but predicting the effect of specific invaders on a given native species remains difficult. Many successful invaders are highly aggressive, while others are not. The highly successful invasive Asian house gecko, Hemidactylus frenatus, has achieved a pan-tropical distribution. We investigated direct interactions between H. frenatus and a sympatric native Australian house gecko (Gehyra dubia) to determine the strength and nature of aggressive exclusion, and which species...

Data from: Giant coral reef fishes display markedly different susceptibility to night spearfishing

Alan R. Pearse, Richard J. Hamilton, John Howard Choat, John Pita, Glenn Almany, Nate Peterson, Grant S. Hamilton & Erin E. Peterson
The humphead wrasse (Cheilinus undulatus) and bumphead parrotfish (Bolbometopon muricatum) are two of the largest, most iconic fishes of Indo-Pacific coral reefs. Both species form prized components of subsistence and commercial fisheries and are vulnerable to overfishing. C. undulatus is listed as Endangered and B. muricatum as Vulnerable on the IUCN Red List of Threatened Species. We investigated how night spearfishing pressure and habitat associations affected both species in a relatively lightly exploited setting; the...

Data from: A fuzzy-set-theory-based approach to analyze species membership in DNA barcoding

Ai-Bing Zhang, Christoph Muster, Hong-Bing Liang, Chao-Dong Zhu, Ross Crozier, Ping Wan, Jie Feng & Robert D Ward
Reliable assignation of an unknown query sequence to its correct species remains a methodological problem for the growing field of DNA barcoding. While great advances have been achieved recently, species identification from barcodes can still be unreliable if the relevant biodiversity has been insufficiently sampled. We here propose a new notion of species membership for DNA barcoding - fuzzy membership, based on fuzzy set theory - and illustrate its successful application to four real datasets...

Data from: Disentangling the effects of key innovations on the diversification of Bromelioideae (Bromeliaceae)

Daniele Silvestro, Georg Zizka & Katharina Schulte
The evolution of key innovations, novel traits that promote diversification, is often seen as major driver for the unequal distribution of species richness within the tree of life. In this study, we aim to determine the factors underlying the extraordinary radiation of the subfamily Bromelioideae, one of the most diverse clades among the neotropical plant family Bromeliaceae. Based on an extended molecular phylogenetic data set, we examine the effect of two putative key innovations, that...
