Article
System of Systems connect complex technological systems (e.g. power plants, transportation, and infrastructure) to provide additional services. Failures in one constituent system, however, can often cascade to other systems within the network. Decision makers need repeatable, generalizable System of System design-for-resilience approaches. Current...
Conference Paper
In this case study we report on the use of a Next Generation Science Standards (NGSS)-aligned form of Structure-Behavior-Function, called Structure-Function-Mechanism (SFM), to teach four high school engineering teachers an approach for Biologically Inspired Design (BID). Functional theories of design describe a natural way in which designers solve...
Conference Paper
Resilience is an emergent property of complex systems that describes the ability to detect, respond, and recover from adversity. Much of the modern world consists of multiple, interacting, and independent agents (i.e. Multi-Agent Systems). However, the process of improving Multi-Agent System resilience is not well understood. We seek to address thi...
Article
Networking complex sociotechnical systems into larger Systems of Systems (SoS) typically results in improved performance characteristics including sustainability, efficiency, and productivity. The response, or lack thereof, of many SoS to unexpected constituent system failures undermines their effectiveness in many cases. SoS performance after faul...
Article
Sustainability of urban areas is paramount in the coming years as cities continue to grow in population and resource consumption. A number of methods to model cities have been developed, including material flow analysis and urban metabolism, but these accounting methods do not fully analyze the complex network dynamics present within cities. Ecolog...

Full-text available
Traditional optimization models often lack a systems-level perspective at conception, which limits their effectiveness. Expanding system boundaries allow scientists and engineers to model complex interactions more accurately, leading to higher efficiency and profitability in industrial systems. Ecological systems have evolved for billions of years...

Full-text available
Biological systems have evolved to retain and recycle materials via decomposer networks. However, engineered systems are often deficient in the employment of decomposers despite their potential to improve efficiency and sustainability. These systems favor unmitigated growth and exploit natural resources, exporting pollutants to the environment as w...

Full-text available
Demands for efficient and resilient food production will increase due to population growth, climate change and other factors. This study compares the additive life cycles of traditional, large-scale lettuce and tilapia production with combined aquaponic agriculture to evaluate these methods based on their material efficiency and their associated en...
Article
Full-text available
Ecology has been used as a metaphor for industries and cities with the goal of creating better systems. The field of industrial ecology incorporates the principles of ecology into industrial network design, but this field often analyzed industries in a vacuum. Similarly, ideas such as urban metabolism and infrastructure ecology have been applied to...
Article
Increasing urbanization places cities at the forefront of achieving global sustainability. For cities to become more sustainable, however, the infrastructure on which they rely must also become more productive, efficient and resilient. Unfortunately the current paradigm of urban infrastructure development is fragmented in approach lacking a systems...
Conference Paper
Ecology is proving to be an innovative source for design principles. Studies have examined how ecological principles can enhance sustainability in industrial networks. Ecologically-inspired manufacturing networks tend to focus on supporting symbiotic relationship formation, creating a cyclical flow structure that has been shown to result in efficie...
Article
Industrial Ecology hypothesises that networks of industries designed to be analogous to the structure and properties of food webs may approach a similarly sustainable and efficient state. Although ecology is the metaphor for designing Eco-Industrial Parks (EIPs), prior research has shown that EIPs are inferior in performance compared to natural eco...
Article
Full-text available
Prey responses to predator cues are graded in intensity in accordance with the degree of threat presented by the predator. In systems in which prey gather information on predators by using chemicals, prey often respond more to the odor of predators that have consumed conspecifics, as opposed to heterospecifics. We investigated the response of a pre...
Article
Biologically Inspired Design (Biomimicry) and Industrial Ecology both look to natural systems to enhance the sustainability and performance of engineered products, systems and industries. Bio-inspired design (BID) traditionally has operated on a unit operation and single product level. In contrast, this paper describes how principles of network org...
Article
A key element for achieving sustainable manufacturing systems is efficient and effective resource use. This potentially can be achieved by encouraging symbiotic thinking among multiple manufacturers and industrial actors and establish resource flow structures that are analogous to material flows in natural ecosystems. In this paper, ecological prin...

Article
Full-text available
The key intended learning outcome of interdisciplinary engineering courses and programs is the development of students' ability to integrate knowledge known as integrated understanding. Still, there are only few examples of assessment tasks designed to deliberately assess this attribute in engineering education, and little is known about how to dev...
Article
Full-text available
We examined whether chemically mediated risk perception by prey and the effects of changes in prey behavior on basal resources vary as a function of the amount of prey biomass consumed by the predator. We studied these issues using a tritrophic system composed of blue crabs, Callinectes sapidus (top predator), mud crabs Panopeus herbstii (intermedi...
Article
When presented with a fine-scale upwelling or downwelling shear flow in a laboratory flume, 2 tropical copepods from the Red Sea, Acartia negligens and Clausocalanus furcatus, performed a set of behaviors that resulted in apparent depth-keeping and the potential for producing patchiness. Analyses of free-swimming trajectories revealed a behavioral...
Article
Cyclical industrial networks are becoming highly desirable for their efficient use of resources and capital. Progress toward this ideal can be enhanced by mimicking the structure of naturally sustainable ecological food webs (FWs). The structures of cyclic industrial networks, sometimes known as eco-industrial parks (EIPs), are compared to FWs usin...
Article
This chapter discusses how animals navigate through chemical plumes to find prey, and the ecological consequences of this process. It emphasizes tools to characterize the hydrodynamic/chemical signal conditions and how these conditions affect navigation. It examines which signals provide information from the plumes and what the informationgathering...
Article
Full-text available
Abstract Nonconsumptive effects (NCEs) have been shown to occur in numerous systems and are regarded as important mechanisms by which predation structures natural communities. Sensory ecology-that is, the processes governing the production, propagation, and masking of cues by ambient noise-provides insights into the strength of NCEs as functions of...

Full-text available
At Georgia Tech in 2005, we developed an interdisciplinary undergraduate semester-long course, biologically inspired design (BID), co-taught each year by faculty from biology and engineering. The objective of this chapter is to share our teaching experience with those interested in teaching such a course themselves. The specific curriculum of a BID...
Article
Greater predator body size is often associated with greater predation risk. According to the threat-sensitive predator avoidance hypothesis, prey should display graded responses to increasing predator body size; in turn, these differences in behaviour should also cause differing indirect effects. Yet, in aquatic systems, where prey often use chemic...

Full-text available
The chemical world of crustaceans is complex and rich in information about features of the environment in which they are found. Consequently, it is not surprising that the chemical senses of crustaceans are used in most aspects of their lives, including reproduction, securing resources, interacting with conspecifics, and avoiding predators. The che...
Chapter
We take a sensory ecological approach to examining the role of chemical information in regulating ecological interactions in molluscan communities. Current and past studies suggest that molluscs can use chemical cues to determine both the type of predator and general information about it's proximity, thus allowing potential prey to evaluate the lev...
Conference Paper
In this paper we use ecology metrics to analyze closed loop manufacturing networks, specifically eco-industrial parks. Eco-industrial parks (EIP) have become a popular manifestation of sustainable initiatives around the world. EIP examples and proposals have met with varying success. We create here three groupings of industrial networks based on th...
Article
The prevalence of inherently unstable intraguild (IG) predation in natural systems suggests that many biotic and abiotic factors, including habitat complexity and population size structure, affect interactions between IG predators and prey. We investigated the role of shared oyster resource use (Crassostrea virginica), predator size, and habitat co...
Conference Paper
Full-text available
We develop a plume tracking algorithm for a swarm of mobile sensing agents in turbulent flow. Inspired by blue crabs, we propose a stochastic model for plume spikes based on the Poisson counting process, which captures the turbulent characteristic of plumes. We then propose an approach to estimate the parameters of the spike model, and transform th...
Article
Despite the well-accepted role of water flow in mediating ecological processes, the spatial and temporal variation of hydrodynamic conditions experienced by organisms is largely unknown in intertidal estuarine habitats. Current ecological and hydrodynamic sampling approaches may prevent adequate assessment of these impacts by confounding spatial an...
Article
Full-text available
Predator body size often indicates predation risk, but its significance in non-consumptive effects (NCEs) and predator risk assessment has been largely understudied. Although studies often recognize that predator body size can cause differing cascading effects, few directly examine prey foraging behavior in response to individual predator sizes or...
Article
Full-text available
A sustainable global community requires the successful integration of environment and engineering. In the public and private sectors, designing cyclical ("closed loop") resource networks increasingly appears as a strategy employed to improve resource efficiency and reduce environmental impacts. Patterning industrial networks on ecological ones has...

Article
Full-text available
Blue crabs can distinguish and navigate to attractive (food) odors even when aversive odors (injured crab metabolites) are released nearby. Blue crabs in these conditions detect the aversive odor and avoid it, but find the attractive source with nearly the same success rate as when the attractive source is presented alone. Spatially and temporally...
Article
The ability of predators to navigate efficiently towards prey patches can determine competitive ability, abundance and distribution of predator or prey species. Slowly moving odour-mediated predators that have a high capacity for temporal integration of signals can successfully navigate prey odour plumes in naturally turbulent environments, but the...
Article
Indirect effects, which can be either positive or negative, may be important in areas containing biotic structure, because such structure can provide refuge and habitat, produce additional sensory cues that may attract predators, and modify the sensory landscape in which predator-prey interactions occur. To determine the indirect effects of biotic...

Full-text available
We designed and implemented a control algorithm for sensor-mediated chemical plume tracking in a turbulent flow environment. In our design, we focused on development of a signal processing strategy capable of replicating behavioral responses of actively tracking blue crabs (Callinectes sapidus) to chemical stimuli. The control algorithm is evaluate...
Presentation
Zooplankton exploit a variety of chemical and fluid mechanical cues in foraging, mate-seeking, and habitat partitioning contexts. To examine the influence of environmental cues on zooplankton aggregations in coastal marine thin layers, a laboratory thin layer mimic was built. The apparatus uses a laminar, planar jet (the Bickley jet) to produce eco...
Article
Full-text available
The chemosensory signal structure governing the upstream progress of blue crabs to an odorant source was examined. We used a three-dimensional laser-induced fluorescence system to collect chemical concentration data simultaneously with behavior observations of actively tracking blue crabs (Callinectes sapidus) in a variety of plume types. This allo...

Full-text available
This study examined the role of broadly distributed sensor populations in chemosensory searching, especially cross-stream heading adjustment. We used three-dimensional laser-induced fluorescence to collect chemical concentration data simultaneously with behavior observations of actively tracking blue crabs (Callinectes sapidus). Our analysis indica...
Conference Paper
Sustainable design is as an important movement in design. Biologically inspired design is a major paradigm for sustainable design. In this paper, we analyze a corpus of biologically inspired design projects in terms of sustainability. We then describe a case study of analogical design of a fog harvesting net, and abstract from it the patterns of Hy...
Chapter
Full-text available
Many animals obtain information about conspecifics or heterospecifics that is transmitted in waterborne chemical plumes or trails. The ability to use chemicals for distance communication minimally requires that the receiver of a chemical signal be able to detect and identify the chemical constituents. Since animals often use plumes or trails to fin...
Conference Paper
Background/Question/Methods In recent decades, both oyster and blue crab populations have suffered significant declines often attributed to coastal development and overfishing. However, little is known about the biotic species interactions, such as trophic cascades, that could affect the stability and resilience of oyster reef communities and in...
Conference Paper
Background/Question/Methods As summarized in a variety of experimental studies and reviews, predators commonly have large impacts on prey populations and community organization through lethal or consumptive effects (CEs) and by nonlethal or nonconsumptive effects (NCEs) whereby predators cause prey to alter their morphology, behavior, and/or habita...
Conference Paper
Background/Question/Methods: Predator foraging success within patchy prey distributions is dependent on the ability of the predator to locate prey patches as well as distinguish patch quality. The success of odor-mediated predators in locating prey patches in estuarine environments is dependent on their ability to detect and follow chemical plumes;...
Article
Predators often have large effects on community structure, but these effects can be minimized in habitats subjected to intense physical stress. For example, predators exert large effects on rocky intertidal communities on wave-protected shores but are usually absent from wave-swept shores where hydrodynamic forces prevent them from foraging effecti...

Mixing upper level undergraduates majoring in engineering with those majoring in biology, we have devised a course on biologically-inspired design (BID) that provides practical training in methods and techniques that facilitate the identification and translation of biological principles into solutions for human challenges. The challenges of interdi...
Article
Blue crabs are cannibalistic, and therefore the scent of injured conspecifics represents both a potential food cue, as well as an indicator of predation risk. We examined the response of blue crabs to conspecific odor alone, as well as in mixtures of attractive cues to determine how animals evaluate and respond to this odor. We explicitly manipulat...
Article
Full-text available
Habitat complexity often modifies rates of prey capture by visual predators, but little is known about how structural features affect non-visual olfactory consumers. Laboratory studies indi- cate that turbulent water flow over complex bedforms mixes chemical information in ways that con- fuse some olfactory foragers but improve the odor-tracking ab...
Article
Blue crabs (Callinectes sapidus) and other aquatic organisms locate food and mates by tracking turbulent odorant plumes. The odorant concentration fluctuates unpredictably due to turbulent transport, and many characteristics of the fluctuation pattern have been hypothesized as useful cues for orienting to the odorant source. To make a direct linkag...
Article
Full-text available
Chemical cues mediate many critical life processes, such as feeding, reproduction, and benthic settling, for aquatic organisms. Depending on the fluid velocity and flow regime, released chemicals are transported via diffusion, laminar advection, or turbulent advection prior to organism reception. Here, we review transport mechanisms and ecological...
Article
Recent studies have shown that the oceanographic distribution of mobile zooplankton can be attributed, at least in part, to foraging and aggregative behaviors. A laboratory system was developed to test the cues that induce these behaviors. The system mimics thin layer structure in the ocean, and the research has focused on calanoid copepods, specif...
Article
Full-text available
Previous studies have shown that prey living under intense consumer pressure possess stronger defenses against consumers than related species in habitats where consumer pressure is low. We tested whether prey sensitivity to risk would be heightened in habitats with elevated preda- tion pressure and accordingly whether prey living in these areas wou...
Article
Full-text available
Many studies have shown that nonlethal predator effects such as trait-mediated interactions (TMIs) can have significant impacts on the structure and function of communities, but the role that environmental conditions play in modulating the scale and magnitude of these effects has not been carefully investigated. TMIs occur when prey exhibit behavio...

Several species and developmental stages of calanoid copepods were tested for responses to environmental cues in a laboratory apparatus that mimicked conditions commonly associated with patches of food in the ocean. All species responded to the presence of phytoplankton by feeding. All species responded by increasing proportional residence time in...
Article
Full-text available
Biologically inspired design (BID) or biomimicry consists of using biological principles to inform engineering designs and applications. As both a method and goal, BID therefore cuts across many disciplines that currently are organized around functional criteria (e.g. mechanical engineering) or levels of inquiry (e.g. cell biology). Two challenges...

Caribbean spiny lobsters display a diversity of social behaviors, one of the most prevalent of which is gregarious diurnal sheltering. Previous research has demonstrated that shelter selection is chemically mediated, but the source of release and the identity of the aggregation signal are unknown. In this study, we investigated the source and speci...
Article
The lethal and nonlethal impacts of predators in marine systems are often mediated via reciprocal detection of waterborne chemical signals between consumers and prey. Local flow environments can enhance or impair the chemoreception ability of consumers, but the effect of hydrodynamics on detection of predation risk by prey has not been investigated...
