Wild populations of Triatoma infestans: Compilation of positive sites and comparison of their ecological niche with domestic population niche
(Elsevier Science, 2017-12)
Background: For several years, the wild populations of Triatoma infestans, main vector of Trypanosoma cruzi causing Chagas disease, have been considered or suspected of being a source of reinfestation of villages. The ...
Using global and regional Species Distribution Models (SDM) to infer the invasive stage of latrodectus geometricus (Araneae: Theridiidae) in the Americas
(Entomological Society of America, 2016)
© The Authors 2016. The brown widow spider, Latrodectus geometricus C. L. Koch, 1841, is a large spider of the family Theridiidae that belongs to a genus of medical interest owing to its potent neurotoxic venom, which ...
Assessing the impact of deforestation and climate change on the range size and environmental niche of bird species in the Atlantic forests, Brazil
Aim Habitat loss and climate change are two major drivers of biological diversity. Here we quantify how deforestation has already changed, and how future climate scenarios may change, environmental conditions within the ...
Sprouts and saplings regeneration niche, crown carbon balance, and crown photosynthetic limitations of Eucryphia cordifolia Cav. plants at field and nursery conditions Nicho de regeneración, balance de carbono y limitaciones de la fotosíntesis a nivel de copa de rebrotes y plantas de eucryphia cordifolia Cav. creciendo en condiciones naturales y de cultivo
(Universidad de Concepción . Facultad de Ciencias Naturales y Oceanográficas . Departamento de Botanica, 2013)
Sprouting is a widespread trait of geographical, ecological and taxonomical scales that allows resource exploitation, space colonization, vegetative reproduction and post-disturbance persistence. It is considered that ...
The dimensionality of ecological networks
How many dimensions (trait-axes) are required to predict whether two species interact? This unanswered question originated with the idea of ecological niches, and yet bears relevance today for understanding what determines ...
Avoidance of achromatic colours by bees provides a private niche for hummingbirds

Daily pattern of locomotor activity of the synanthropic spiders Loxosceles laeta and Scytodes globula
(American Arachnological Society, 2018)
The locomotor activity of the Chilean recluse spider Loxosceles laeta (Nicolet, 1849), and the spitting spider, Scytodes globula Nicolet, 1849, were studied in the laboratory under controlled conditions (LD 12:12). In ...
Potential Climate-Driven Impacts on the Distribution of Generalist Treefrogs in South America
(Herpetologists League, 2016-03-01)
Climate change is considered a serious threat to biodiversity. If populations no longer have physiological, morphological, or behavioral adaptations to withstand novel climatic conditions, or if they are unable to change ...
