<title>Predictive tools for integrated socio-environmental systems</title>

<description>Combining dynamical population ecology models with policy scenarios is an
important approach in both population biology and bioeconomics.
At its best, this approach may provide predictive understanding of future behavior.
But in complex socio-environmental systems (SES),
applying such theory requires large amounts of data and system understanding.
Reduced-complexity representations, like networks, provide promise but are not
yet linked to dynamic theory.
I am Co-leading a SESYNC working group focused on addressing this gap.</description>

<description>&lt;&ndash; Click the link for a video of the talk!
Forecasting or projecting involves a wide range of timescales and associated assumptions about human behavior. At one end of the spectrum are very-near-term physical forecasts (like the weather) and at another end are long-run, scenario-based projections (like global emissions pathways). Ecological forecasts span a range of timescales and assumptions about human behavior. The main message of this talk was that in developing and thinking about &ldquo;ecological forecasting&rdquo; as a discipline, we must be clear about whether and to what extent a forecast is incorporating human behavior.</description>

<description>Human livelihoods and ecosystem fates are often linked by water.
I have a longstanding interest in the population biology of rivers,
and in using theory and methods from computational ecology to understand
and manage rivers to sustain aquatic life and nature&rsquo;s benefits to people.
I am co-leading a SESYNC working group focused on
systems where shallow aquifers link groundwater use to instream flows,
leading to tradeoffs between users and potential tipping points.</description>

<title>Efficient pedigree recording for fast population genetics simulation</title>
<link>https://www.ashander.info/posts/2018/11/tree-sequence-recording-in-forward-simulations/</link>

<description>We describe a way to record all of the gene-trees along a segment of genome, as well as how genetic material is passed down through the pedigree, during a forwards-time population genetic simulation. To make effective use of this information, we describe both efficient storage methods for this embellished pedigree as well as a way to remove all information that is irrelevant to the genetic history of a given set of individuals, which dramatically reduces the required amount of storage space.</description>

<title>The mechanisms of phenology: the patterns and processes of phenological shifts</title>
<link>https://www.ashander.info/posts/2018/10/phenology-mechanisms-pattern-process/</link>

<guid>https://www.ashander.info/posts/2018/10/phenology-mechanisms-pattern-process/</guid>
<description>From the abstract
Species across a wide range of taxa and habitats are shifting phenological events in response to climate change. While advances are common, shifts vary in magnitude and direction within and among species, and the basis for this variation is relatively unknown. We examine previously suggested patterns of variation in phenological shifts in order to understand the cue–response mechanisms that underlie phenological change. Here, we review what is known about the mechanistic basis for nine factors proposed to predict phenological change (latitude, elevation, habitat type, trophic level, migratory strategy, ecological specialization, species’ seasonality, thermoregulatory mode, and generation time).</description>

<description>Inference of process from pattern is a major methodological challenge,
yet increasingly available &ldquo;big&rdquo; phenotypic and genomic data promises to shed light on
otherwise-difficult-to-collect vital rates in natural populations.
I develop and apply methods to use this data to

<title>Eco-evolutionary dynamics in human-dominated systems</title>

<description><p>In my Ph.D., I sought to understand the consequences of trait change due to
evolutionary and plastic responses in changing environments, developing
theory on population dynamics resulting from these processes in stochastic environments. Using this theory
I showed how environmental autocorrelation controls the benefits to plasticity in new environments.
Further, these theories provide predictions about the entire distribution of population sizes and fitness
levels within a population.</p>
<p>My M.Sc. research focused on the evolutionary ecology of sea lice, farmed and
wild salmon. Recently, I&rsquo;ve become particularly interested in the ways in
which the combination of wild salmon migrations and salmon farm management
can influence chemical resistance evolution on farms, potentially providing a
benefits to people (which some have called &ldquo;EVOsystem services&rdquo;).</p>

<title>Predicting evolutionary rescue via evolving plasticity in stochastic environments</title>
<link>https://www.ashander.info/posts/2016/09/noisy-plastic-evolutionary-rescue/</link>

<guid>https://www.ashander.info/posts/2016/09/noisy-plastic-evolutionary-rescue/</guid>
<description>Phenotypic plasticity and its evolution may help evolutionary rescue in a novel and stressful environment, especially if environmental novelty reveals cryptic genetic variation that enables the evolution of increased plasticity (panels a and b in the figure below). But the environmental stochasticity ubiquitous in natural systems may alter these predictions (panel c). This might occur, for example if high plasticity amplifies phenotype-environment mismatches. Although previous studies have highlighted this potential detrimental effect of plasticity in stochastic environments, they have not investigated how it affects extinction risk in the context of evolutionary rescue and with evolving plasticity.</description>

<description>It’s a long tradition in statistical graphics going from Tufte back toTukey andClevelandto advise against using bar charts. Many folks, includingme, have pejorativelycalled the common (in ecology, at least) bar chart + SE a “dynamite plot”.Although Ben Bolker has questionedthe wisdom of this sentiment, I think in most cases they’re worth avoiding. (I discuss this morein “When and here are dynamite plots appropriate” below.</description>

<description>Version of notes for discussion I led in Sebastain Schreiber&rsquo;s for PBG 271 Research Conference in Ecology on &ldquo;Life history evolution in stochastic environments&rdquo;.
Reading Childs et al and Stearn&rsquo;s piece on Bernoulli Childs, Metcalf and Rees (2010) present a plant-focused review of bet-hedging, including a review of essential theory. As in many papers on bet-hedging, these authors distiguish between conservative and diversified strategies.
Geometic mean fitness concept When fitness is temporally variable, the appropriate measure of evolutionary success is the expected geometric mean growth rate of a genotype.</description>

<title>Understanding the joint effects of plastic and evolutionary change on demography from time series</title>

<description>Background/Question/Methods
In nature, selection often fluctuates, but observed changes in traits may owe not only to selection but plasticity. Further, changes in traits due to selection and to plasticity do not have equal demographic effects: the cost of selection is paid through declines in population number or growth rate. Thus, observed trajectories of trait value and population number can depend on interactions between plasticity, evolution and environment. The extent to which these interactions affect observed trajectories depends on the demographic context.</description>

<description>This video and poster introduces our project, &ldquo;Trade-Offs and Synergies in Floodplain Management - A Historical-Ecological Approach&rdquo;
Floodplains have long been favored sites for agriculture and settlement due to their fertility, flat topography, and proximity to rivers for easy transport of goods. To reduce flood risk attendant with flood plain settlement, extensive flood protection structures have been built, including elaborate networks of levees. These modifications have greatly reduced the ecological benefits that intact river-flood plain systems provide.</description>

<description>Exchange of diseases between domesticated and wild animals is a rising concern for conservation. In the ocean, many species display life histories that separate juveniles from adults. For pink salmon (Oncorhynchus gorbuscha) and parasitic sea lice (Lepeophtheirus salmonis), infection of juvenile salmon in early marine life occurs near salmon sea-cage aquaculture sites and is associated with declining abundance of wild salmon. Here, we develop a theoretical model for the pink salmon/sea lice host–parasite system and use it to explore the effects of aquaculture hosts, acting as reservoirs, on dynamics.</description>

<description>Human food production activities can dominate natural systems, altering ecological and evolutionary aspects of the environment. Disease-mediated interactions are of particular concern. For example, parasites may &ldquo;spill-over&rdquo; from farms to wildlife. Parasites isolated on farms can evolve resistance to treatment chemicals , but &ldquo;spill-back&rdquo; from wildlife to farms may alter evolutionary dynamics. Here, we consider exchange of parasites (Lepeophtheirus salmonis) between wild (Oncorhynchus gorbuscha) and farmed salmon. We derive and analyze discrete-time models that implicitly include wild salmon migrations.</description>

<description>We help companies to grow by helping them to raise capital&hellip; Companies that grow create wealth. This, in turn, allows people to have jobs that create more growth and more wealth. It&rsquo;s a virtuous cycle. We have a social purpose. &mdash; Lloyd Blankfein
Ed Abbey wrote that Blankfein&rsquo;s virtuous cycle, growth for the sake of growth, is &ldquo;the logic of the cancer cell&rdquo;. Whether or not you buy this anti-captialist mumbo jumbo, there is something cancerous about a jobless, finance-led recovery.</description>

<title>Science education and uncertainty</title>

<description>A brand new &ldquo;-gate&rdquo; on the climate science front has me thinking about the relationship between science and the public. A big issue in communicating science stems from the fundamental disconnect between science as practiced and science as taught in introductory formats, e.g. in high school.
Most people learn science as fact. The reality is emerging scientific knowledge (in fact all scientific knowledge) is uncertain. Those who disagree idealogically with the state of scientific knowlege highlight this uncertainty.</description>

<title>Wrong, not confused</title>

<description>Quoting Turchin (1998) quoting Hull (1988) quoting Bacon (?) :
In science it is better to be wrong than confused.
The point is, though a mathematical model that purports to repesent reality will be wrong, one with clear definitions and assumptions can be helpful. Mathematical modeling is a tool to move from confusion about a process to making clear (if wrong) statements about that process.</description>

<title>Negative results or technical problems?</title>

<guid>https://www.ashander.info/posts/2009/11/omitting-negative-results/</guid>
<description>True or false: &ldquo;Non-publication of negative results is extraordinarily common in science&hellip;.&rdquo; ?
This comes from biomed world, specifically protein design, where some awesome claims&mdash;design of protein receptors to detect TNT (the explosive) among other things&mdash;have come under scrutiny. The lab involved recently retracted some other work.
The quotation above is from Loren Looger, who was a PhD student on the project. He&rsquo;s referrring to unreported instances where a designed protein didn&rsquo;t bind the target and concludes that the omission &ldquo;did not seem inappropriate.</description>

<description>&ldquo;Salish Sea&rdquo; is on its way to being an official name in the U.S. and Canada. Can Cascadia be far behind?
Stefan Freelan at WWU made the beautiful map of the region here. His page has lots of details about the region and the history of the term.</description>

<description>An NYT column reports on fur seal whiskers serving as biogeochemical records. This kind of data is more and more common, e.g. otoliths, feathers, shells. What can scientists do with it?
I&rsquo;ve mainly seen biogeochemical markers used to infer relatively static traits of individual like origin and age or to make coarse-scale statements about diet (trophic level). The fur seal study got trophic information at a bit finer scale (within-year variation), connecting that to yearly migrations.</description>

<description>Today I mailed my absentee ballot for the S.F. municipal election. The Good People footed the bill to send it up here to me in Edmonton, I&rsquo;m not sure whether they intended to spring for the return journey.
The only clue was the cryptic (to me) &ldquo;U.S. Postage Paid. 39 USC 3406. PAR AVION&rdquo; printed in the upper right hand corner of the return envelope. I&rsquo;m not sure why it would say &lsquo;par avion&rsquo; if they weren&rsquo;t intending to pay, but if they were why would it say &lsquo;U.</description>

<title>Market substitution in aquaculture</title>

<guid>https://www.ashander.info/posts/2009/10/market-substitution-aquaculture/</guid>
<description>A recent article in BioScience [1] focused on the relationship between aquaculture and conservation. This topic is quite interesting to me, but it&rsquo;s obviously subtle. I don&rsquo;t have well-defined thoughts except that (i) aquaculture could theoretically relieve pressure on some wild fisheries and (ii) certain aquaculture operations have proven negative impacts on some ecosystems.
This paper aims to highlight broad trends in capture and culture fisheries and quantify effects on biodiversity.</description>

<title>Canadian lag</title>

<description>The Coastal Voices blog at Living Oceans had an intersting post up remarking on the disparity between Canadian&rsquo;s self-image as environmental progressives and reality&mdash;that they appeaer to lag the U.S. in marine protection and other conservation issues. The author wondered why this might be. I left a comment, which I&rsquo;ll expand on here.
I&rsquo;ve had similar thoughts and my guess is this blind spot for domestic environmental issues owes to Canada&rsquo;s: (i) vast wild-lands (natural resources), (ii) very low population and (iii) long-standing economic dependence on extraction of those resources.</description>

<description>Title: Background Template: etc
I am a Postdoctoral Scholar in the Shaffer lab at UCLA. Working in collaboration with Peter Ralph (now at U of Oregon), we are developing methods that use genomic data to inform demographic models of the desert tortoise (Gopherus agassizii). These models will enable us to analyze effects of scenarios for development in the Mojave desert on the population viability of the tortoise.
In September 2016, I received my Ph.</description>

<description> Title: This site Template: etc
A long-overdue website redesign. My overall goal is to combine personal academic website (papers, projects, CV, etc) along with a platform for quick blog-like entries (perhaps later adding disqus integration, share buttons etc).
Currently, pull data from figshare for results. Eventually I&rsquo;d like to automatically pull data from other sources (eg github).
Details templated (jinja2) index to pull from results (papers, preprints), themes (overall project categories) and notes (blog-like) will add projects (work in progress, github repos, project descriptions) as top-level category soon these categories are repeated on top nav rotating banner image with some shots from old website Engine + hosting Pelican engine for a static site to generate results, projects, notes from markdown hosting on github Style bootstrap, using bootswatch yeti via pelican-bootstrap3 very light additional css (eg padding elements) customizations to pelican-bootstrap3 include rotating banner bar (via javascript in base template), limiting sidebar display to blog-like (called notes here) entries, and adding neighbor arrows to blog posts </description>

<description>Title: Funding Template: etc
My postdoctoral research in the Shaffer lab at UCLA is funded by the US Fish and Wildlife Service.
My Ph.D. support has included a two-year traineeship with the REACH IGERT, as well as a one-year Bridge RA-ship funded through the same program.
My M.Sc. was supported largely by the Pacific Institute of Mathematical Sciences International Graduate Training Centre in mathematical biology. I also received a (1 year) University of Alberta Master&rsquo;s Scholarship, which paid for tuition during my first term.</description>
