Machines that Dream

Benjamin David Robert Bogart
Watching and Dreaming is a body of work that enables the viewer to peer inside the “mind” of a machine to observe its perceptions, mind wanderings, and dreams. This is not a metaphorical representation of dreams, nor a technical exercise in AI such as DeepDream [1] but the realization of a computational model of dreaming informed by cognitive neuroscience. This level of description avoids biases towards Jungian and Freudian psychology that assume dreaming is exclusively...

Dataset: Resource limitation has a limited impact on the outcome of virus-fungus co-infection in an insect host

Pauline Deschodt & Jenny Cory
Infection by pathogens is strongly affected by the diet or condition of the prospective host. Studies that examine the impact of diet have mainly focussed on single pathogens; however, co-infections within a single host are thought to be common. Different pathogen groups might respond differently to resource availability and diverse infections could increase the costs of host defence, meaning the outcome of mixed infections under varying dietary regimes is likely to be hard to predict....

Bumble bee occurrences of North America from 1805–2020

Leif Richardson, Laura Melissa Guzman, Hanna Jackson, Sarah Johnson, Lora Morandin & Leithen M'Gonigle
Bumble bee occurrence data used for "Climate change winners and losers among North American bumble bees": These data comprise 649 407 specimen records from 48 species and spans 1805–2020. These records have been compiled from a variety of collections and sources with reputable origin. Data contributors are listed in: https://www.leifrichardson.org/bbna.html

Climate and conspecific density inform phenotypic forecasting of juvenile Pacific salmon body size

Marta Ulaski, Heather Finkle, Anne Beaudreau & Peter Westley
1. Predicting effects of climate on fitness-linked phenotypic traits, such as body size, is important for the management and conservation of species in the face of global change. During sensitive life stages, small changes in mean trait values can have large effects on survival and population productivity. 2. The transition from freshwater to saltwater by migrating anadromous fishes such as Pacific salmon (genus Oncorhynchus) is a critical life history transition, where survival is mediated by...

A deglacial hazard cascade exemplified by the landslide, tsunami and outburst flood at Elliot Creek, Southern Coast Mountains, British Columbia, Canada

Marten Geertsema, Brian Menounos, Gemma Bullard, Jonathan Carrivick, John Clague, Chunli Dai, Davide Donati, Goran Ekstrom, Jennifer Jackson, Patrick Lynett, Manuele Pichierri, Andy Pon, Dan Shugar, Doug Stead, Justin Del Bel Belluz, Pierre Friele, Ian Giesbrecht, Derek Heathfield, Tom Millard, Sasha Nasonova, Andrew Schaeffer, Brent Ward, Darren Blaney, Erik Blaney, Camille Brillon … & Meghan Sharp
We describe and model the evolution of a recent landslide and outburst flood in the southern Coast Mountains, British Columbia, Canada. About 18 Mm3 of rock descended 1000 m from a steep valley wall and traveled across the toe of a glacier before entering a 0.6 km2 glacier lake and producing a >100-m high wave. Water overtopped the lake outlet and scoured a 10-km long channel before depositing debris on a 2 km2 fan below...

Data from: Watershed classification predicts streamflow regime and organic carbon dynamics in the Northeast Pacific Coastal Temperate Rainforest

Ian Giesbrecht, Suzanne Tank, Gordon Frazer, Eran Hood, Santiago Gonzalez Arriola, David Butman, Dave D'Amore, David Hutchinson, Allison Bidlack & Ken Lertzman
Watershed classification has long been a key tool in the hydrological sciences, but few studies have been extended to biogeochemistry. We developed a combined hydro-biogeochemical classification for watersheds draining to the coastal margin of the Northeast Pacific coastal temperate rainforest (1,443,062 km2), including 2,695 small coastal rivers (SCR) and 10 large continental watersheds. We used cluster analysis to group SCR watersheds into 12 types, based on watershed properties. The most important variables for distinguishing SCR...

Marbled Murrelets prefer stratified waters close to freshwater inputs in Haida Gwaii, BC, Canada

Sonya Pastran, Mark Drever & David Lank
The Marbled Murrelet (Brachyramphus marmoratus) is a small seabird that is currently listed as threatened in Canada. Understanding this species’ marine habitat preferences plays a vital role in our ability to focus conservation planning. We used the longest-running at-sea survey dataset available in British Columbia to examine hotspot persistence and habitat use at Laskeek Bay, Haida Gwaii, BC. The Laskeek Bay Conservation Society has been conducting spring and summer surveys along fixed transect routes in...

Code, data and supplementary material from: Analyzing phylogenetic trees with a tree lattice coordinate system and a graph polynomial

Pengyu Liu, Priscila Biller, Matthew Gould & Caroline Colijn
This dataset includes code, used and generated data for the experiments in the paper Analyzing Phylogenetic Trees with a Tree Lattice Coordinate System and a Graph Polynomial, and the supplementary material of the paper. The paper introduces representation and comparison methods for rooted unlabelled phylogenetic trees based on a tree lattice that serves as a coordinate system for rooted binary trees with branch lengths and a graph polynomial that fully characterizes tree shapes. The methods...

Interactive effects of multiscale diversification practices on farmland bird stress

Elissa Olimpi, Hallie Daly, Karina Garcia, Victoria Glynn, David Gonthier, Claire Kremen & Leithen M'Gonigle
Farmland diversification practices (i.e., methods used to produce food sustainably by enhancing biodiversity in cropping systems) are sometimes considered beneficial to both agriculture and biodiversity, but most studies of these practices rely on species richness, diversity, or abundance as a proxy for habitat quality. Biodiversity assessments may miss early clues that populations are imperiled when species presence does not imply persistence. Physiological stress indicators may help identify low-quality habitats before population declines occur. We explored...

Using GBIF to Demonstrate Colonial Legacies on Biodiversity Data

Ryan S. Mohammed, Melissa Kemp, Michelle J. LeFebvre, Alexis M. Mychajliw, Grace Turner, Kelly Fowler, Michael Pateman, Maria A. Nieves-Colón, Lanya Fanovich, Siobhan B. Cooke, Liliana M. Dávalos, Scott M. Fitzpatrick, Christina M. Giovas, Myles Stokowski & Ashley A. Wrean
Biologists recognize the Caribbean archipelago as a biodiversity hotspot and employ it for their research as a “natural laboratory”, but do not always appreciate that these ecosystems are in fact palimpsests shaped by multiple human cultures over millennia. We discuss two case studies of the Caribbean’s fragmented natural history collections, the effects of differing legislation and governance by the region’s multiple nation states. We use digital natural history specimen data from GBIF to demonstrate how...

Epigenetic induction may speed up or slow down speciation with gene flow: code and data

Philip Greenspoon, Hamish Spencer & Leithen M'Gonigle
Speciation is less likely to occur when there is gene flow between nascent species. Natural selection can oppose gene flow and promote speciation if there is variation in ecological conditions among the nascent species' locations. Previous theory on ecological speciation with gene flow has focused primarily on the role of genetic variation in ecological traits, largely neglecting the role of non-genetic inheritance or transgenerational plasticity. Here we present the simulation code and data from models...
