local extinction of the asian tiger mosquito (aedes albopictus) following rat eradication on palmyra atoll.the asian tiger mosquito, aedes albopictus, appears to have been extirpated from palmyra atoll following rat eradication. anecdotal biting reports, collection records, and regular captures in black-light traps showed the species was present before rat eradication. since then, there have been no biting reports and no captures over 2 years of extensive trapping (black-light and scent traps). by contrast, the southern house mosquito, culex quinquefasciatus, was abundant before and after rat eradica ...201829491026
forecasting the spatial and seasonal dynamic of aedes albopictus oviposition activity in albania and balkan countries.the increasing spread of the asian tiger mosquito, aedes albopictus, in europe and us raises public health concern due to the species competence to transmit several exotic human arboviruses, among which dengue, chikungunya and zika, and urges the development of suitable modeling approach to forecast the spatial and temporal distribution of the mosquito. here we developed a dynamical species distribution modeling approach forecasting ae. albopictus eggs abundance at high spatial (0.01 degree wgs8 ...201829432489
areas with high hazard potential for autochthonous transmission of aedes albopictus-associated arboviruses in germany.the intensity and extent of transmission of arboviruses such as dengue, chikungunya, and zika virus have increased markedly over the last decades. autochthonous transmission of dengue and chikungunya by aedes albopictus has been recorded in southern europe where the invasive mosquito was already established and viraemic travelers had imported the virus. ae. albopictus populations are spreading northward into germany. here, we model the current and future climatically suitable regions for ae. alb ...201829914102
larval superiority of culex pipiens to aedes albopictus in a replacement series experiment: prospects for coexistence in germany.the asian tiger mosquito aedes albopictus is an extremely invasive, globally distributed and medically important vector of various human and veterinary pathogens. in germany, where this species was recently introduced, its establishment may become modulated by interspecific competition from autochthonous mosquito species, especially culex pipiens (s.l.). while competitive superiority of ae. albopictus to cx. pipiens (s.l.) has been described elsewhere, it has not been assessed in the epidemiolog ...201829394910
new dates on dingo bones from madura cave provide oldest firm evidence for arrival of the species in australia.the dingo is the only placental land mammal aside from murids and bats to have made the water crossings to reach australia prior to european arrival. it is thought that they arrived as a commensal animal with people, some time in the mid holocene. however, the timing of their arrival is still a subject of major debate with published age estimates varying widely. this is largely because the age estimates for dingo arrival are based on archaeological deposit dates and genetic divergence estimates, ...201830026564
letting the 'cat' out of the bag: pouch young development of the extinct tasmanian tiger revealed by x-ray computed tomography.the tasmanian tiger or thylacine (thylacinus cynocephalus) was an iconic australian marsupial predator that was hunted to extinction in the early 1900s. despite sharing striking similarities with canids, they failed to evolve many of the specialized anatomical features that characterize carnivorous placental mammals. these evolutionary limitations are thought to arise from functional constraints associated with the marsupial mode of reproduction, in which otherwise highly altricial young use the ...201829515893
effects of human impacts on habitat use, activity patterns and ecological relationships among medium and small felids of the atlantic forest.competition theory and niche theory suggest that two morphologically similar species may coexist by reducing the overlap of at least one dimension of their ecological niche. the medium and small neotropical felids are an interesting group of carnivore species for studying intraguild competition. due to differences in size it is expected that the larger ocelot exert strong interference competition on the smaller felids (southern tiger cat, margay and jaguarundi); which, in turn, may exert exploit ...201830067785
