Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Task partitioning in insect societies. I. Effect of colony size on queueing delay and colony ergonomic efficiency [PDF]
, 1999 The collection and handling of colony resources such as food, water, and nest construction material is often divided into subtasks in which the material is passed from one worker to another. This is known as task partitioning.

Resilience Practices and Post‐Traumatic Growth Among Sudanese IDPs
Conflict Resolution Quarterly, EarlyView.ABSTRACT In this paper we examine the resilience of internally displaced persons (IDPs) in Sudan who have endured various forms of suffering resulting from being targeted or trapped by militants involved in large‐scale violence. Upon escaping the conflict zones, the civilians exhibit strength, adaptability, and wisdom in the face of various threats to ...

Reconstructing the functions of endosymbiotic Mollicutes in fungus-growing ants
eLife, 2018 Mollicutes, a widespread class of bacteria associated with animals and plants, were recently identified as abundant abdominal endosymbionts in healthy workers of attine fungus-farming leaf-cutting ants.

Bacterial microbiomes from vertically-transmitted fungal inocula of the leaf-cutting ant Atta texana [PDF]
, 2016 Microbiome surveys provide clues for the functional roles of symbiotic microbial communities and their hosts. In this study, we elucidated bacterial microbiomes associated with the vertically transmitted fungal inocula (pellets) used by foundress queens ...

Ecography, EarlyView.Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Occurrence of polygyny in Acromyrmex subterraneus molestans Santschi 1925 (Hymenoptera: Formicidae) [PDF]
Ciência Rural, 2004 Polygyny denotes the coexistence of two or more mated and fertile queens in the colony. A colony of Acromyrmex subterraneus molestans Santschi containing 14 queens was collected on campus of the Universidade Federal de Viçosa, Brazil, aiming to verify if

Nordic Journal of Botany, EarlyView.Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

Mating system and population genetic structure of the bulldog ant Myrmecia pavida [PDF]
, 2013 Understanding the evolution of the alternative mating strategies of monandry and polyandry is a fundamental problem in evolutionary biology because of the cost-benefit trade-offs associated with mating for females.
