SUMMARY:Géza Meszéna (Eötvös University): Coexistence\, niche\, adaptation and all that...
DESCRIPTION:Abstract:\nWhy are there so many animals? According an old idea\, it is because there are so many different possibilities for life to adapt to. I’ll argue that it is still true\, and truer than the suggested alternatives. The challenge is to establish the precise mathematical treatment at this level of generality without losing the reach to the phenomenal complexity of the ecosystems. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Theresa Ong (Dartmouth College): Complex hysteretic patterns: hidden loops and ecological traps
DESCRIPTION:NOTE:\n Because of the asynchronous transition to Summer Time\, the usual time of the seminar (9 a.m. Pacific) is one hour earlier in Europe: 4 p.m. London and 5 p.m. Paris. \nAbstract:\nCritical transitions whereby small changes in conditions can cause large and irreversible changes in ecosystem states are a cause of increasing concern in ecology. Here\, I focus on the irreversibility of these transitions\, formally known as hysteresis. I will discuss a variety of complicated hysteretic patterns derived from theory and experiments\, which include “unattainable” stable states that once lost may never be recovered. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:György Barabás (Linköping): Coexistence and parameter sensitivity in stationary aperiodic environments
DESCRIPTION:Abstract:\nFirst\, I present a method for calculating how average population densities respond to parameter perturbations when the dynamics are periodic\, and show that this practical problem holds a strong connection with basic questions of coexistence. I then generalize this result to stationary nonperiodic density fluctuations. I finish by discussing the connection with existing formalisms for understanding coexistence in variable environments. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Priyanga Amarasekare (UCLA): Predicting the effects of climate warming: from chemistry to evolution
DESCRIPTION:Abstract\nI want to make the argument that understanding life on earth requires developing theory that integrates across levels of information\, from chemistry to evolution. I am going to focus on temperature variation and phenotypic plasticity\, not least because temperature is integral to all life processes\, and climate warming poses one of the greatest threats to life on earth. Predicting the effects of warming requires knowing whether organisms have sufficient plasticity to respond to current levels of warming\, and whether plasticity can evolve fast enough to keep pace with warming. But\, existing plasticity is the result of past evolution\, while future plasticity is the result future evolution. My thesis is that chemistry is integral to both understanding past evolution and predicting future evolution. I will present theory and data to support this idea and discuss future research directions. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Masato Yamamichi (The University of Queensland): How does rapid evolution promote species coexistence?
DESCRIPTION:Note: The event takes place 3 hours earlier than usual\, because of the location of our lecturer. He will speak at midnight\, local time\, even in this way. \nAbstract:\nPrevious studies have revealed that microevolution (i.e.\, temporal changes in allele frequencies) is pervasive in the wild and may be an important factor for understanding various ecological dynamics. Here\, I show how rapid evolution can promote species coexistence via density-dependent sexual and social selection (intraspecific adaptation load: Yamamichi et al. 2020 Trends Ecol. Evol.) and resource-dependent adaptive foraging in limit cycles (relative nonlinearity: Yamamichi & Letten 2021 Ecol. Lett.). Then I will discuss the potential synthesis of theories on species coexistence and eco-evolutionary dynamics. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Cinzia Soresina (University of Graz): The influence of cross-diffusion in pattern formation: multistability and Hopf bifurcations
DESCRIPTION:Abstract\nThe Shigesada-Kawasaki-Teramoto model (SKT) was proposed to account for stable inhomogeneous steady states exhibiting spatial segregation\, which describes a situation of coexistence of two competing species. Even though the reaction part does not present the activator-inhibitor structure\, the cross-diffusion terms are the key ingredient for the appearance of spatial patterns. We provide a deeper understanding of the conditions required on both the cross-diffusion and the reaction coefficients for non-homogeneous steady states to exist\, by combining a detailed linearised and weakly non-linear analysis with advanced numerical bifurcation methods via the continuation software pde2path. In particular\, we study the role of the additional cross-diffusion term in pattern formation\, showing that the bifurcation diagram undergoes major deformations leading to multistability regions. The presence of time-periodic spatial pattern appearing via Hopf bifurcation points is also investigated. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Chuliang Song (McGill University): An environment-dependent framework to study ecological networks
DESCRIPTION:Abstract: Ecological networks—how species interactions are organized within ecological communities—are highly structured\, which has motivated generations of ecologists to elucidate how these structures affect species coexistence. Unfortunately\, we still do not have a clear and consistent answer about the link between network structure and species coexistence. A possible explanation is that most of the studies do not take into account that the environment affects both network structure and species coexistence due to the multidimensional and changing nature of environmental factors. In this context\, the structural stability approach provides a theoretical framework grounded on biological realism to quantitatively link network structure\, species coexistence\, and environmental factors. In this talk\, I will introduce the theoretical framework and computational tools of the structural stability approach\, and present the empirical validation using field and experimental observations. \nThe Zoom link is the usual: https://liu-se.zoom.us/j/63158449287

SUMMARY:Neo Martinez (Indiana University): Predicting Ecosystem Phenotype from Community Genotype: Can Allometric Trophic Network Theory Help Meet the Challenge?
DESCRIPTION:Abstract:\nTheoretical ecology has investigated a series of concepts from stability and complexity through biodiversity and ecosystem function to coexistence and tipping points for which empirical data typically plays a less-than-satisfying role. To coax theoretical ecology towards increased empirical relevance and broader scientific synthesis\, I propose that environmental biologists focus on predicting key characteristics of an ecosystem from the genotypes within its constituent communities. Such metagenomes effectively identify the organisms and their interactions within ecosystems. Following the first of several “virtual cells” built by systems biologists that predicts a human pathogen’s phenotype from its genotype\, powerful social (e.g.\, structured collaborations)\, scientific (e.g.\, networks of networks) and technical (e.g.\, computer and data science) concepts for accomplishing the proposed task will be described along with a plausible workflow based on allometric trophic network theory. Anticipated benefits include more integrated\, mechanistic\, and predictive theory of how ecosystem structure and function emerge from organisms interacting within a habitat. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Rafael D'Andrea (Stony Brook University): Counting niches: Can spatial patterns reveal niche partitioning in tropical forests?
DESCRIPTION:Abstract: \nWe investigate the idea that tropical biodiversity is maintained by a combination of niche segregation and niche sharing among species by asking whether tree species in Barro Colorado Island\, Panama\, fall into groups differing by the local conditions where they typically occur. We first group together species often found near each other\, then show that the resulting three groups are statistically associated with distinct local nutrient levels. Finally\, we find clear distinctions among those groups in traits associated with life history strategies. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries \neventbrite link (for reminders): https://www.eventbrite.co.uk/e/theoretical-ecology-seminar-series-tickets-119884512805

SUMMARY:Jacob D. O’Sullivan (Queen Mary): The emergent macroecology of Lotka-Volterra metacommunities
DESCRIPTION:Abstract: \nFor decades Lotka-Volterra community models have been used to try to understand how ecological interactions may drive community-scale properties such as species richness\, network structure\, and species abundance distributions; in short the various dimensions of biodiversity. Here I show how extending the basic community models into spatially and environmentally heterogeneous landscapes can help us understand how local scale ecological processes – abiotic and biotic filtering\, and dispersal – can propagate up the organisational hierarchy to determine regional scale patterns in biodiversity. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries

SUMMARY:Mathew Leibold (University of Florida): Linking process to pattern in community assembly in diverse metacommunities
DESCRIPTION:Abstract: \nI’m interested in exploring the degree to which theory on ‘disordered systems’ to community assembly can be linked to statistical methods of pattern analysis. Here\, I hope to describe the problem and outline some possible approaches and answers. By doing so\, I hope to generate interest and discussion on possible solutions. \nZoom link: https://liu-se.zoom.us/j/63158449287 \nPast lectures are on the YouTube channel: https://www.youtube.com/c/TheoreticalEcologySeminarSeries

SUMMARY:Laura Dee (Colorado Boulder): Putting ecological theory to work for conservation
DESCRIPTION:Abstract. Two grand challenges of our time are climate change and biodiversity loss. This talk focuses on the fundamental question of: to what extent can ecological theory help us understand the consequences of these global changes to inform conservation?  I will present two examples investigating this larger question: 1) the consequences of extreme events in boreal forests for ecological stability versus ecosystem services outcomes’ and the 2) vulnerability of food webs versus ecosystem services to species losses in coastal food webs.  In the first case\, commonly used ecological measures also fall short of predicting disturbance impacts on forest ecosystem services–  exhibiting low correlations or systematic biases. In the other case\, food web robustness is strongly related to ecosystem service robustness in aggregate\, but different types of ecosystem services vary dramatically in their robustness to species’ losses. Together\, this work highlights that the complex nature of socioeconomic and ecological systems create challenges for extrapolating ecological theory to understand threats from global change for conservation goals .  Thus\, I will highlight exciting research avenues for discussion on how ecological theory to contribute to conservation and interdisciplinary research in our inherently socio-environmental systems.

SUMMARY:Rachel Germain (UBC): Theory in service of empirical research: examples from experiments on the ecology and evolution of species coexistence
DESCRIPTION:Science operates through a healthy feedback between theory and experiments. As an empiricist who uses theory for different purposes\, I will begin by describing some barriers to more fully integrating theory into empirical research in ecology and evolution (and how to overcome those barriers). I will then describe two applications of theory in my own work: 1. how empirical findings have inspired new questions to be addressed theoretically\, and\, 2. how ecological theories guide the questions I ask and the experiments I design (and some challenges to doing so). Within this overarching framework\, I will focus on several projects\, including: how spatial scale has counter intuitive effects on the evolution of life history strategies\, how species coexistence evolves on microevolutionary and macroevolutionary timescales\, and how coexistence theory can provide insights for speciation.
