Article
Biological collections are important repositories of biodiversity, as they include various types of data potentially useful to different areas of science and can contribute to the establishment of biodiversity conservation policies. For a long time, scientific collections were considered only as physical databases; in this context Harold G. Fowler...

Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costl...
Article
Solenopsis invicta and Solenopsis saevissima are the most common fire ants in Brazil. Environmental disturbances favour the colony dispersal of both species, particularly those with an anthropogenic origin. However, the frequencies of the species can vary according to the amount of anthropogenic disturbances. Crops near native vegetation fragments...

Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant sp...

Mutualistic association between Azteca Forel, 1878 ants and Cecropia Loefl. plants are one of the most studied interactions in Neotropics, however, natural history studies of Azteca species still poorly investigated due to the great effort required to conduct detailed descriptive studies. Here, we describe biological aspects of Azteca muelleri Emer...

Twigs in the litter derived from the fragmentation of tree branches form one microhabitat, where entire colonies of ants, both leaf litter and arboreal species, can be found. The objective was to survey ant species that are presente in both the leaf litter and twigs simultaneously. We describe the nest type, the social structure of the colonies and...

Resumo: As coleções de referência são importantes acervos para a biodiversidade. Nelas, estão contidas amostras representativas e informações biológicas de regiões específicas, que servem de base para muitos estudos científicos. A coleção de referência do Laboratório de Mirmecologia do Alto Tietê reúne uma das mais expressivas coleções de formigas...

Resumo: A serapilheira é diversa em micro-habitats que são explorados por diferentes espécies de formigas para nidificação, e esses recursos são fundamentais para a diversificação de suas comunidades. Nos galhos oriundos da fragmentação de ramos de arbóreas é possível encontrar colônias com adultos alados e imaturos de formigas de serapilheira e ar...

... Solenopsis invicta is native to South America and is largely distributed in the Pantanal region, at the headwaters of the Paraguay River, an area composed of savannas and seasonally flooded wetlands; its distribution ranges from Porto Velho (Rondônia, north Brazil) to the extreme south of the country (Pitts et al. 2018). But its occurrence has been extending to regions of the Brazilian coast into areas of the Atlantic Domain through introductions by anthropogenic means, with the expansion being discussed as a result of a bottleneck effect (Nagatani et al. 2022;Ramalho et al. 2023). The species has gained worldwide recognition for its remarkable success as an invasive ant in southern United States, Asia and even Europe, earning its place among the top 100 most harmful invasive species globally, according to the IUCN/SSC Invasive Species Specialist Group. ...
... Ants are important components of edaphic communities and represent one of the most abundant populations in coffee systems (Teixeira;Silva;Mendonça, 2014;Guimarães et al., 2016;Sales;Baldiand;Queiroz, 2018). These insects have been used as bioindicators as they are sensitive to environmental changes, abundant and present in disturbed or undisturbed habitats (Brown-Junior, 2000;Philpott et al., 2010;Ribas et al., 2012;Rodríguez-de-León et al., 2019). ...
... Azteca species exhibit a range of nesting habits (Longino 2007). Many species in this genus keep mutualistic associations with their host plants, such as Cecropia Loefl., 1758 (Urticaceae), whose structure offers both shelter and food to the ants, which in return, give to the plant protection against herbivory (Hölldobler & Wilson 1990;Dejean et al. 2008;Oliveira et al. 2015;Carneiro et al. 2018;Nagatani et al. 2021). Others build carton nests with several chambers hanged on tree branches (Forel 1904;Bondar 1939;Cuezzo 2003). ...
... Wood is an important habitat for many species including ants, termites, beetles, and many other arthropods (Ulyshen 2016;King et al. 2018;Ulyshen & Sobotnik 2018). Wood -both living and dead -can provide suitable places for nest sites (Blüthgen & Feldhaar 2010;King et al. 2018;Ulyshen & Sobotnik 2018;Fernandes et al. 2020), and is a source of food, e.g., for some termites and beetles (Ulyshen 2016;Ulyshen & Sobotnik 2018). Decaying wood is also a good habitat for microorganisms such as fungi and bacteria (Ulyshen 2016;Ulyshen & Sobotnik 2018;Lupala et al. 2019). ...
... The latter are more restricted in their nature than museum collections and are usually the product of specific research projects. They give the researcher in charge and his or her research group quick and in-depth access to the species of a particular place or region (see Souza-Campana et al. 2020), and can be formed by different types of material. Local collections store information on the communities inhabiting a particular region, with its diverse landscapes and floristic formations. ...
