Adaptation drives the diversity of form and function observed in nature and is key to population persistence. Yet, adaptation can be limited by a lack of genetic variation, trade-offs, small population size, and constraints imposed by coevolving interacting species. These limits may be particularly important to the colonizing populations in restored ecosystems, such as native prairies restored through seed sowing. Here, we discuss how constraints to adaptation are likely to play out in restored prairie ecosystems and how management decisions, such as seed mix composition, prescribed fire, and strategic site selection, might be used to overcome some of these constraints. Although data are still limited, recent work suggests that restored prairie populations likely face strong selection and that promoting the potential for adaptation in these systems may be necessary for restoring populations both now and in the face of further global change.

Click Through Rate

Native advertising is a type of online advertising that matches the form and function of the platform on which it appears. In practice, the choice between display and in-feed native advertising presents brand advertisers and online news publishers with conflicting objectives. Advertisers face a trade-off between ad clicks and brand recognition, whereas publishers need to strike a balance between ad clicks and the platform’s trustworthiness. For policy makers, concerns that native advertising confuses customers prompted the U.S. Federal Trade Commission to issue guidelines for disclosing native ads. This research aims to understand how consumers respond to native ads versus display ads and to different styles of native ad disclosures, using randomized online and field experiments combining behavioral clickstream, eye movement, and survey response data. The results show that when the position of an ad on a news page is controlled for, a native ad generates a higher click-through rate because it better resembles the surrounding editorial content. However, a display ad leads to more visual attention, brand recognition, and trustworthiness for the website than a native ad.

Language produced in a specific event of communication will have its form and function. Some messages are delivered in direct ways meaning the form and the functions are symmetric; some others are delivered in indirect ways, asymmetric. Direct or indirect ways will give different perceptions to those who receive the content of the message. Considering the face of receivers is one of the principles that should be made by policy makers as they communicate with people in public space. This article aims to explain the forms of language used to prohibit littering and the way the maker of prohibition thinks about the writing of littering. The research is conducted by using non-participatory observation method. This, then, is followed by applying note taking technique and recording. The result shows mostly the writings of littering prohibition are made an indirect way and less number in indirect way. Having a direct way means society is placed as subordinate in relation to the authorities. Even though less in number, indirect littering prohibition shows some writings see an equal position between the writer and reader. Both take a similar point of view on littering.

Genetic variation in fitness is required for the adaptive evolution of any trait but natural selection is thought to erode genetic variance in fitness. This paradox has motivated the search for mechanisms that might maintain a population's adaptive potential. Mothers make many contributions to the attributes of their developing offspring and these maternal effects can influence responses to natural selection if maternal effects are themselves heritable. Maternal genetic effects (MGEs) on fitness might, therefore, represent an underappreciated source of adaptive potential in wild populations. Here we used two decades of data from a pedigreed wild population of North American red squirrels to show that MGEs on offspring fitness increased the population's evolvability by over two orders of magnitude relative to expectations from direct genetic effects alone. MGEs are predicted to maintain more variation than direct genetic effects in the face of selection, but we also found evidence of maternal effect trade-offs. Mothers that raised high-fitness offspring in one environment raised low-fitness offspring in another environment. Such a fitness trade-off is expected to maintain maternal genetic variation in fitness, which provided additional capacity for adaptive evolution beyond that provided by direct genetic effects on fitness.

Abstract Trade-offs caused by the use of an anatomical apparatus for more than one function are thought to be an important constraint on evolution. However, whether multifunctionality suppresses diversification of biomechanical systems is challenged by recent literature showing that traits more closely tied to trade-offs evolve more rapidly. We contrast the evolutionary dynamics of feeding mechanics and morphology between fishes that exclusively capture prey with suction and multifunctional species that augment this mechanism with biting behaviors to remove attached benthic prey. Diversification of feeding kinematic traits was, on average, over 13.5 times faster in suction feeders, consistent with constraint on biters due to mechanical trade-offs between biting and suction performance. Surprisingly, we found that the evolution of morphology contrasts directly with these differences in kinematic evolution, with significantly faster rates of evolution of head shape in biters. This system provides clear support for an often postulated, but rarely confirmed prediction that multifunctionality stifles functional diversification, while also illustrating the sometimes weak relationship between form and function.

Inferior temporal cortex (IT) is a key part of the ventral visual pathway implicated in object, face, and scene perception. But how does IT work? Here, I describe an organizational scheme that marries form and function and provides a framework for future research. The scheme consists of a series of stages arranged along the posterior-anterior axis of IT, defined by anatomical connections and functional responses. Each stage comprises a complement of subregions that have a systematic spatial relationship. The organization of each stage is governed by an eccentricity template, and corresponding eccentricity representations across stages are interconnected. Foveal representations take on a role in high-acuity object vision (including face recognition); intermediate representations compute other aspects of object vision such as behavioral valence (using color and surface cues); and peripheral representations encode information about scenes. This multistage, parallel-processing model invokes an innately determined organization refined by visual experience that is consistent with principles of cortical development. The model is also consistent with principles of evolution, which suggest that visual cortex expanded through replication of retinotopic areas. Finally, the model predicts that the most extensively studied network within IT—the face patches—is not unique but rather one manifestation of a canonical set of operations that reveal general principles of how IT works.

Burn injuries are responsible for a significant portion of surgically treatable morbidity throughout the world and particularly in underdeveloped and developing countries. Intentional flame, chemical, and contact burns are unfortunately a common mechanism of injury. It is estimated that intentional chemical burns are responsible for between 2 and 20% of burn injuries seen at burn centers in lower income countries. Women are commonly targeted and the perpetrators are often known to the victims. The combination of a high disease prevalence, limited surgical and anesthetic resources, a vulnerable patient population, and largely disfiguring, nonlethal injuries present unique challenges for the reconstructive surgeon who may not encounter such cases regularly. In this article, we present a case of a 16-year-old female who sustained severe, full-thickness burns to the face including eyelids, neck, abdomen, and upper extremities after an intentional acid attack. She began her treatment course with us approximately 1 year after the injury. The deformities of her oral and periorbital regions presented particularly difficult reconstructive problems, including impending visual loss. Using plastic surgical principalization, we provided our patient adequate restoration of facial form and function through numbers of interventions using fundamental and state-of-the-art techniques.

Abstract The 2010 Deepwater Horizon (DWH) oil spill resulted in extensive damage to the northern Gulf of Mexico ecosystem. Resulting fines and penalties have triggered one of the largest ecological restoration efforts in U.S. history. Nearly $20 Billion in funding from oil spill-related claims and settlements will be available in the coming years for environmental restoration and economic recovery. At the same time, climate change is also impacting ecosystem form and function in the Gulf region, which could undermine the long-term sustainability of projects by limiting their useful life or impeding anticipated benefits over time (e.g., ecosystem services, flood protection). These challenges can be considered and addressed in project planning, selection and adaptive management phases of restoration. If decision-makers do not consider the longevity of projects in the face of climate-related stressors, in 30 to 50 years there could be very little to show for a $20 Billion investment, with the Gulf ecosystem still in need of extensive restoration but without the monetary resources to accomplish restoration goals and mitigate climate-related impacts. This paper provides a framework for decision makers to consider how to incorporate climate change considerations for wetland restoration activities related to the DWH spill.

Plant life-history strategies are constrained by cost-benefit trade-offs that determine plant form and function. However, despite recent advances in the understanding of trade-offs for vegetative and physiological traits, little is known about plant reproductive economics and how they constrain plant life-history strategies and shape interactions with floral visitors. Here, we investigate plant reproductive trade-offs and how these drive interactions with floral visitors using a dataset of 17 reproductive traits for 1,506 plant species from 28 plant-pollinator studies across 18 countries. We tested whether a plant's reproductive strategy predicts its interactions with floral visitors and if the different reproductive traits predict the plant's role within the pollination network. We found that over half of all plant reproductive trait variation was explained by two independent axes that encompassed plant form and function. Specifically, the first axis indicated the presence of a trade-off between flower number and flower size, while the second axis indicated a pollinator dependency trade-off. Plant reproductive trade-offs helped explain partly the presence or absence of interactions with floral visitors, but not differences in visitation rate. However, we did find important differences in the interaction level among floral visitor guilds on the different axes of trait variation. Finally, we found that plant size and floral rewards were the most important traits in the understanding of the plant species network role. Our results highlight the importance of plant reproductive trade-offs in determining plant life-history strategies and plant-pollinator interactions in a global context.
