Predators As Agents of Selection and Diversification
diversity Review Predators as Agents of Selection and Diversification Jerald B. Johnson * and Mark C. Belk Evolutionary Ecology Laboratories, Department of Biology, Brigham Young University, Provo, UT 84602, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-801-422-4502 Received: 6 October 2020; Accepted: 29 October 2020; Published: 31 October 2020 Abstract: Predation is ubiquitous in nature and can be an important component of both ecological and evolutionary interactions. One of the most striking features of predators is how often they cause evolutionary diversification in natural systems. Here, we review several ways that this can occur, exploring empirical evidence and suggesting promising areas for future work. We also introduce several papers recently accepted in Diversity that demonstrate just how important and varied predation can be as an agent of natural selection. We conclude that there is still much to be done in this field, especially in areas where multiple predator species prey upon common prey, in certain taxonomic groups where we still know very little, and in an overall effort to actually quantify mortality rates and the strength of natural selection in the wild. Keywords: adaptation; mortality rates; natural selection; predation; prey 1. Introduction In the history of life, a key evolutionary innovation was the ability of some organisms to acquire energy and nutrients by killing and consuming other organisms [1–3]. This phenomenon of predation has evolved independently, multiple times across all known major lineages of life, both extinct and extant [1,2,4]. Quite simply, predators are ubiquitous agents of natural selection. Not surprisingly, prey species have evolved a variety of traits to avoid predation, including traits to avoid detection [4–6], to escape from predators [4,7], to withstand harm from attack [4], to deter predators [4,8], and to confuse or deceive predators [4,8]. -

Niche Evolution Evolutionary Biology Oxford Bibliographies
8/23/2016 Niche Evolution Evolutionary Biology Oxford Bibliographies Niche Evolution Alex Pyron LAST MODIFIED: 26 MAY 2016 DOI: 10.1093/OBO/97801999417280075 Introduction The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and longterm regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes. General Overview Niche evolution has rarely, if ever, been addressed in depth as a standalone topic. -

Recent invaders tend to produce fewer, but larger, juveniles, delay the onset but increase the duration of reproduction, survive longer, and senesce more slowly than earlier ones. These traits are associated with higher ranks in a competitive hierarchy established in a previous study. However, the endemic species, now nearly extinct in the island, is inferior to the other three with respect to both competition and colonization traits, violating the trade-off assumption.

Interpretation of Models of Fundamental Ecological Niches and Species’ Distributional Areas
Biodiversity Informatics, 2, 2005, pp. 1-10 INTERPRETATION OF MODELS OF FUNDAMENTAL ECOLOGICAL NICHES AND SPECIES’ DISTRIBUTIONAL AREAS JORGE SOBERÓN Comisión Nacional de Biodiversidad, México, and Instituto de Ecología, UNAM, México AND A. TOWNSEND PETERSON Natural History Museum and Biodiversity Research Center, University of Kansas, Lawrence, Kansas 66045 USA Abstract.—Estimation of the dimensions of fundamental ecological niches of species to predict their geographic distributions is increasingly being attempted in systematics, ecology, conservation, public health, etc. This technique is often (of necessity) based on data comprising records of presences only. In recent years, modeling approaches have been devised to estimate these interrelated expressions of a species’ ecology, distributional biology, and evolutionary history—nevertheless, a formal basis in ecological and evolutionary theory has largely been lacking. In this paper, we outline such a formal basis to clarify the use of techniques applied to the challenge of estimating ‘ecological niches;’ we analyze example situations that can be modeled using these techniques, and clarify interpretation of results. Key words.—ecological niche, fundamental niche, realizad niche, geographic distribution The fact that, at certain scales, climatic and occurrences with data sets summarizing climatic, physical factors affect profoundly the distributions topographic, edaphic, and other ‘ecological’ of species has been known for a very long time. In dimensions (in the form of GIS layers); the last two decades, mathematical techniques combinations of environmental variables most designed to estimate the geographic extent of the closely associated with observed presences of “fundamental ecological niche” (FN), or subsets of species can then be identified and projected onto it, defined mostly in coarse-scale climatic landscapes to identify appropriate regions, as dimensions [the “bioclimatic envelope” or climatic above. -
Annual Meeting 1998
PALAEONTOLOGICAL ASSOCIATION 42nd Annual Meeting University of Portsmouth 16-19 December 1996 ABSTRACTS and PROGRAMME The apparatus architecture of prioniodontids Stephanie Barrett Geology Department, University of Leicester, University Road, Leicester LE1 7RH, UK e-mail: [email protected] Conodonts are among the most prolific fossils of the Palaeozoic, but it has taken more than 130 years to understand the phylogenetic position of the group, and the form and function of its fossilized feeding apparatus. Prioniodontids were the first conodonts to develop a complex, integrated feeding apparatus. They dominated the early Ordovician radiation of conodonts, before the ozarkodinids and prioniodinids diversified. Until recently the reconstruction of the feeding apparatuses of all three of these important conodont orders relied mainly on natural assemblages of the ozarkodinids. The reliability of this approach is questionable, but in the absence of direct information it served as a working hypothesis. In 1990, fossilized bedding plane assemblages of Promissum pulchrum, a late Ordovician prioniodontid, were described. These were the first natural assemblages to provide information about the architecture of prioniodontid feeding apparatus, and showed significant differences from the ozarkodinid plan. The recent discovery of natural assemblages of Phragmodus inflexus, a mid Ordovician prioniodontid with an apparatus comparable with the ozarkodinid plan, has added new, contradictory evidence. Work is now in progress to try and determine whether the feeding apparatus of Phragmodus or that of Promissum pulchrum is most appropriate for reconstructing the feeding apparatuses of other prioniodontids. This work will assess whether Promissum pulchrum is an atypical prioniodontid, or whether prioniodontids, as currently conceived, are polyphyletic. -

It is made available under aCC-BY 4.0 International license. Abstract Fitness is typically represented in heavily simplified terms in evolutionary genetics, often using constant selection coefficients. This excludes fundamental ecological factors such as dynamic population size or density-dependence from the most genetically-realistic treatments of evolution, a problem that inspired MacArthur's influential but problematic r/K theory. Following in the spirit of r/K-selection as a general-purpose theory of density-dependent se- lection, but grounding ourselves empirically in \primary strategy" trait classification schemes like Grime's triangle, we develop a new model of density-dependent selection which revolves around territorial contests. To do so, we generalize the classic lottery model of territorial acquisition, which has primarily been used for studying species co-existence questions, to accommodate arbitrary densities. -
Limits to Species Richness in a Continuum of Habitat Heterogeneity: an ESS Approach
Evolutionary Ecology Research, 2000, 2: 293–316 Limits to species richness in a continuum of habitat heterogeneity: An ESS approach William A. Mitchell* Department of Zoology, University of Wisconsin, Madison, WI 53706, USA ABSTRACT I use a co-evolutionary model to investigate the co-existence of species in ecological and evolutionary time in an environment that comprises a continuum of habitat heterogeneity. The model considers the ecology and evolution of communities organized by a trade-off in foraging costs over the environmental continuum. I assume that foragers use an optimal patch departure rule for depleting environments, where the rule itself depends on both the habitat and the forager’s phenotype, which is a heritable evolutionary strategy. I consider the effects of three variables on co-evolutionarily stable co-existence: (1) travel cost, (2) maintenance and replace- ment cost, and (3) the range of habitat heterogeneity. When travel cost is positive, it, as well as the other two variables, affects species richness. Increasing either travel cost or maintenance cost results in a decrease in richness. Increasing habitat heterogeneity can increase species richness. Keywords: co-evolution, evolutionarily stable strategy, habitat selection, species richness, travel cost. INTRODUCTION Species richness results from a combination of processes occurring at different spatial scales. At the provincial scale, immigration, dispersal and source–sink dynamics influence richness (Holt, 1985, 1993; Ricklefs, 1987, Pulliam, 1988). At the local scale, species inter- actions such as competition may be important (Rosenzweig, 1981; Tilman, 1982). To pre- dict species richness and how it is expected to change with environmental conditions requires an understanding of the importance and relative contributions of both types of processes (Holt, 1993). -

Butfailure to take into account the effect of temporalfluctuation in population size (FPS) on Ne may routinely lead to unrealistically optimistic viability assessments. We thus evaluate a technique that accounts for the effect of FPS on Ne. Using time series of annual counts of 48free-ranging animal populations, we show that Ne is dependent on timescale: as more census records are incorporated, estimates of FPS tend to increase, and thus estimates of N tend to decrease. -

Previous research has emphasised the ecological and evolutionary singularity of these environments and their great conservation value, as they are extremely endangered and also include a highly specialised biota with a high degree of endemism and genetic diversity. However, until recently, our knowledge about the biogeographical patterns and evolutionary processes of the lineages inhabiting these particular systems has been very sparse. This paper is a compilation and summary of the principal results obtained from various recent studies that were developed in the framework of the PhD thesis of the first author and focused on the water beetle diversity of the Mediterranean inland saline waters. The evolution of salinity tolerance, the main factors driving diversification on saline lineages and the application of all this information to provide relevant data for the conservation of aquatic saline biodiversity are addressed.
