Coping with temperature extremes: thermal tolerance and behavioral plasticity in desert leaf-cutting ants (Hymeno ptera: Formicidae) across an altitudinal gradient
(Oesterreichische Gesell Entomofaunistik, 2020-06-10)
Current approaches to assess and predict the impact of climate warming on ectotherms are largely based on their physiological sensitivity to temperature. However, these physiological studies provide little insight into the ...
Appetitive and aversive learning of plants odors inside different nest compartments by foraging leaf-cutting ants
(Pergamon-Elsevier Science Ltd, 2018-08)
Cues inside the nest provide social insect foragers with information about resources currently exploited that may influence their decisions outside. Leaf-cutting ants harvest leaf fragments that are either further processed ...
Avoidance of plants unsuitable for the symbiotic fungus in leaf-cutting ants: Learning can take place entirely at the colony dump
(Public Library of Science, 2017-03-08)
Plants initially accepted by foraging leaf-cutting ants are later avoided if they prove unsuitable for their symbiotic fungus. Plant avoidance is mediated by the waste produced in the fungus garden soon after the incorporation ...
Observation of leaf-cutting ants foraging on wild mushrooms
(Birkhauser Verlag Ag, 2012-05-25)
This study reports on the observation of an unusual behavior in leaf-cutting ants: foraging on wild mushrooms. A colony of Acromyrmex lundi in Buenos Aires (Argentina) was observed intensively harvesting basidiomes (mushroom ...
Wood-rotting basidiomycetes associated with declining native trees in timber-harvesting compartments of the Garden Route National Park of South Africa
(Wiley Blackwell Publishing, Inc, 2017-12)
Trees in the Garden Route National Park (GRNP) indigenous forests in South Africa are selectively harvested for timber based on criteria that include signs and symptoms induced by wood-rotting fungi. However, virtually ...
Complete mitogenome of the biocontroller fungus Purpureocillium sp. (Ascomycota, Ophiocordycipitaceae, Hypocreales)
(Taylor and Francis Ltd., 2018-01-01)
The strain Purpureocillium sp. UdeA0106 is an antagonist of nematodes, fungi, and garden symphylans from crops with high economic importance in Colombia (Salazar 2013; Salazar et al. 2014; Cardona et al. 2014; Gallego ...
Termites and necrophagous insects associated with early Pleistocene (Gelasian) Australopithecus sediba at Malapa, South Africa
(Elsevier Science, 2020-12)
This study focuses on two early Pliestocene Australopithecus sediba hominin specimens and associated fauna from Malapa, South Africa. These specimens have been interpreted as having fallen through a shaft opening into a ...
Leaf spots of calibrachoa caused by Nigrospora oryzaeManchas foliares em calibrachoa causadas por Nigrospora oryzae
(Sociedade Brasileira de Floricultura e Plantas Ornamentais, 2020-08)
Calibrachoa hybrida (calibrachoa, million bells) is a flowering ornamental with increasing importance due to the existence of many successful cultivars for growing indoors in containers and planting in the garden and ...
Diversity of mycobiota in colonies of different species of leaf-cutting ants and sampling sites across ArgentinaDiversidad de micobiota en diferentes especies de hormigas cortadoras de hojas y sitios de Argentina
(Asociación Argentina de Ecología, 2017-12)
Las hormigas de la familia Attini son un grupo monofilético que incluye más de 230 especies distribuidas exclusivamente en el Nuevo Mundo. Todas las hormigas Attini superiores se alimentan de un hongo que cultivan dentro ...
Simulated folivory increases vertical transmission of fungal endophytes that deter herbivores and alter tolerance to herbivory in Poa autumnalis
(Oxford University Press, 2020-05)
• Background and Aims: The processes that maintain variation in the prevalence of symbioses within host populations are not well understood. While the fitness benefits of symbiosis have clearly been shown to drive changes ...
