Nest-site is an important resource for cavity-nesting ants, what limits colony establishment and structures ant community composition through competition. In ecosystems frequently disturbed by firecontinuous of new colonies crucial to the process natural succession. Based on this perspective, we tested hypothesis that fire reduces amount cavities nesting (e.g., hollow branches, dry leaves curled, galls), with negative impact biodiversity. We searched added artificial-nests assess whether...
Abstract Plants bearing extrafloral nectaries ( EFN s) vary the secretion of nectar between day and night, which creates turnover in composition interacting ant species. Daily variation species foraging on vegetation is commonly observed, but its mechanisms are poorly understood. We evaluated daily availability interspecific aggressiveness ants as possible regulatory ant–plant interactions. hypothesized that (i) plants would interact with more during periods higher (ii) aggressive compete...
Diaspore (e.g. seeds, fruits) dispersal is pivotal for plant communities and often involves several steps different dispersing agents. Most studies focusing on diaspore by animals have highlighted the role of vertebrates, neglecting ants in non‐myrmecochorous plants. especially relevant current scenario declining vertebrate populations and, consequently, collapse system large‐seeded Although can never compensate service provided they mitigate impact decline via removal diaspores deposited...
Protected areas are crucial sanctuaries for biodiversity, strictly prohibiting the direct exploitation of natural resources and helping to maintain viable populations communities. However, even species within these face challenges from climate changes. This study compared present distribution five woody (Aspidosperma tomentosum, Kielmeyera coriacea, Peixotoa tomentosa, Qualea multiflora, Senna velutina) with their projected (in 2080–2100) in 30 protected Brazilian national parks. Our...
Ant-diaspore interactions are directly related to fruit consumption, seed predation and dispersal, being determinant for the plant fitness. However, although abundant diversified, these ecological have been neglected in network studies. Understanding structure of networks is first step preserving functions. describing not enough; we need understand what mechanisms behind patterns. In this study, time, describe ant-diaspore network, considering only that can benefit plants, separating it into...
Abstract: Primary seed dispersal of many rain-forest seeds occurs through defecation by mammals. Dung beetles are attracted to the defecations and their dung-processing behaviour these insects change initial pattern deposition. Final deposition patterns, i.e. where how deposited after dung beetle activity has taken place, may strongly depend on size. In this study we addressed following question: Do different sizes have patterns processing? We conducted a field experiment in lowland...
1. Harvester ants perform important ecological functions, such as seed predation and redistribution of nutrients in the soil, through a complex interactions. Most studies are static descriptions network structure, while their temporal organisations factors that modulate it have been neglected. 2. This study describes organisation influence climatic variables (e.g. temperature rainfall) on structure between harvester ant species its food resources (seeds invertebrates) Brazilian savanna over...
Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, regulators plant growth reproduction in most terrestrial ecosystems. Further, ants are widely used bioindicators the impact land use. We gathered information ant species Atlantic Forest South America. The ATLANTIC ANTS data set, which is part SERIES papers, a compilation records from collections (18,713 records), unpublished (29,651 published...
Abstract Biotic communities in heterogeneous agricultural landscapes can be shaped by both the land use of local patches and structure surrounding landscapes. However, studies usually focus on one or other factor, limiting our ability to propose management guidelines for conservation biodiversity human‐modified We used a site‐landscape design multi‐model inference assess effects use, landscape structure, their interactions, dung beetle assemblages Brazilian Cerrado , hotspot. captured...
Fire is one of the most relevant ecological disturbances in nature. Little known about effects fire on biodiversity ecosystems like rupestrian grasslands, which share characteristics with savanna and forest biomes. Brazilian grasslands are part an endangered ecosystem that has been modified by anthropogenic events have become more intense recent decades. In this study, we evaluated ground arboreal ant assemblages through a two-year monitoring program (24 monthly samplings). We found does not...
1. Harvester ants are major seed predators in arid environments. However, given that many harvester partly omnivorous and therefore potentially attracted to the elaiosomes of myrmecochorous seeds, it is unclear if these act as or dispersers when removing seeds. 2. We describe outcomes interactions between ant, Pogonomyrmex naegelii , plant, Microstachys serrulata a Brazilian savanna. We: (i) evaluated role elaiosome removal by P. ; (ii) investigated fate viability removed seeds; (iii) tested...
ABSTRACT Main Animals not only forage for abundant and nearby resources, but their diets can also be influenced by abiotic geographic factors. This often results in non‐random interactions among species. We investigate how seed density, distance from nest, (e.g., climate stability, temperature, precipitation) factors latitude, elevation continental hemisphere) influence the removal of food items (i.e., seeds dead arthropods) Pogonomyrmex Location South North America, Patagonia to Rocky...
The rupestrian complex is a montane transitional vegetation type between the Brazilian Savanna (‘Cerrado’) and Atlantic Forest, frequently threatened by human activities. In this study, we evaluated recovery to fire disturbance of ant fauna in an environment evolved under regime. We confirmed that diversity recovers quickly after fire. However, our results show assemblage burned areas presented greater ant’s foraging activity, here detected as higher abundance. composition changed over time,...
Studies comparing different land covers clearly show that land-use change commonly affects animal communities and the ecological functions they play in ecosystems. However, we lack a good understanding of effects more subtle changes, those occurring within cover type, can have on animals, if these are also mediated by shifts community attributes. We studied two important dung beetles tropical planted pastures with exotic African grasses. Due to differences management, varied grass cover,...
