Recent developments in design and manufacturing have greatly expanded the space for functional part production by enabling control of structural details at small scales to inform behavior whole-structure level. This can be achieved with cellular materials, such as honeycombs, foams lattices. Designing structures materials involves answering an important question: What is optimum unit cell application interest? There currently no classification framework that describes spectrum methodology...
The amount of energy consumed within an average city block is order magnitude higher than that in any other ecosystem over a similar area. This driven by human food inputs, but the consequence these resources for urban animal populations poorly understood. We investigated role foods ant diets across urbanization gradient Manhattan using carbon and nitrogen stable isotopes. found some—but not all—ant species living Manhattan's most urbanized habitats had δ 13 C signatures associated with...
Summary How species respond to temperature change depends in large part on their physiology. Physiological traits, such as critical thermal limits ( CT max and min ), provide estimates of performance but may not capture the full impacts fitness. Rather, likely a combination traits—including limits—that vary among species. Here, we examine how correlate with main components that influence fitness ants. First, compare affected colony survival growth two ant differ responses warming field—...
A field-based climate warming experiment reveals a loss of dynamical community stability due to altered species interactions.
Dominance rank in animal societies is correlated with changes both reproductive physiology and behavior. In some social insects, dominance status used to determine a division of labor, where few colony members reproduce while most remain functionally sterile. Changes reproduction behavior this context must be coordinated through crosstalk between the brain system. We investigated role for biogenic amines forming connection ant Harpegnathos saltator. species, workers engage an elaborate...
Few studies have quantified the relative importance of direct effects climate change on communities versus indirect that are mediated thorough species interactions, and limited evidence is conflicting. Trait-based approaches been popular in change, but can they be used to estimate effects? At level, thermal tolerance a trait often predict winners losers under scenarios change. But might also inform when interactions likely important because only subsets will able exploit available warmer...
Phenotypic plasticity allows organisms to respond changing environments throughout their lifetime, but these changes are rarely reversible. Exceptions occur in relatively long-lived vertebrate species that exhibit seasonal brain size, although similar have not been identified short-lived species, such as insects. Here, we investigate reproductive workers of the ant Harpegnathos saltator . Unlike most H. capable sexual reproduction, and they compete a dominance tournament establish group...
Abstract Architected materials such as lattices are capable of demonstrating extraordinary mechanical performance. Lattices often used for their stretch-dominated behavior, which gives them a high degree stiffness at low-volume fractions. At the other end spectrum, bending-dominated tend to be more compliant and interest energy absorption Here, we report class ultra-compliant interwoven that demonstrate up an order magnitude improvement in compliance over traditional counterparts similar...
Physiological intolerance of high temperatures places limits on organismal responses to the temperature increases associated with global climatic change. Because ants are geographically widespread, ecologically diverse, and thermophilic, they an ideal system for exploring extent which physiological tolerance can predict environmental Here, we expand simple models that use thermal warming. We investigated degree changes in abundance under warming reflect reductions niche space their foraging....
Social dominance hierarchies are widespread, but little is known about the mechanisms that produce nonlinear structures. In addition to despotic hierarchies, where a single individual dominates, shared exist, multiple individuals occupy rank. vertebrates, these complex relationships thought develop from interactions require higher cognition, similar cases of have been found in social insects. Combining empirical observations with modeling approach, we show all three hierarchy...
Abstract Extreme developmental plasticity within the eusocial insects defines separation between queen and worker castes. The switch these 2 pathways is thought to be under tight social control. Although a large emphasis has been placed on effect of larval nutrition caste determination, workers many species have no direct control over feeding. This may particularly relevant early evolution ants, when behaviors that allow fine nutrition, such as mouth-to-mouth food exchange larvae workers,...
We develop a fluid mechanical model of the arterial tree in order to address key question what determines heart rate mammals. propose that frequency pulsatile pressure gradient, which minimizes resistance flow and facilitates movement, coincides with physiological rate. Using data from literature on 95 mammals as function body mass, radius aorta we construct target curve cardiac versus aortic radius. This serves benchmark for comparison our model's results. Our elastic one-dimensional flow,...
<title>Abstract</title> Increasing urban temperatures due to the heat island effect are associated with widespread biodiversity declines. Because cities distributed across diverse climatic zones, effects of on may vary geographically. Here, we examined how warming influences ant communities four U.S. that span 6.6° latitude and differ by 4.1°C in average summer temperature. We sampled ants using baits placed at base a single common tree species along an temperature gradient within each city....
Abstract Nests provide a buffer against environmental variation, but conditions may also vary at different locations within nest. Conditions can based on abiotic factors, such as moisture and temperature, well biotic the presence of microbes potential pathogens. Therefore, characterizing how animals adjust their position inside nests to track microclimate preferences while same time preventing pathogen exposure is necessary understand benefits provide. Here we studied colonies acorn‐nesting...
Abstract Because ectotherm activity and metabolism are sensitive to temperature, terrestrial arthropods may be especially responsive ongoing climatic warming. Here, we quantified responses of arthropod abundance two years warming in an outdoor temperature manipulation experiment at Duke Forest, North Carolina, USA. Nine open‐top chambers were individually heated year‐round from 1.5° 5.5°C above ambient temperature. From monthly pitfall trapping, collected identified 4,468 representing 24...
Abstract Biodiversity provides a massive library of ideas for bio-inspired design, but the sheer number species to consider can be daunting. Current approaches sifting through biodiversity identify relevant biological models include searching champion adapters that are particularly adept at solving specific design challenge. While adapter approach has benefits, it tends focus on narrow set popular while neglecting majority species. An alternative is comparative method, which leverages by...
