Description and distribution of Desmacella hyalina sp. nov. (Porifera, Desmacellidae), a new cryptic demosponge in glass sponge reefs from the western coast of Canada

Law LK, Reiswig HM, Ott BS, McDaniel N, Guillas KC, Kahn AS, Dinn C, Leys SP
Glass sponges (Porifera, Hexactinellida) form globally unique reefs that support deep-sea biodiversity in the Canadian northeast Pacific. In February 2017, the largest known reefs were protected within the Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area...

Schlägel, Ulrike E, Lewis, Mark A.
Animals of many species demonstrate movement behaviour in which decisions are based on a variety of information. Effects of resources have been studied widely, often under the assumption that the environment is constant over the course of the study. Much less understood is the role of dynamic...

Detecting minimum energy states and multi-stability in nonlocal advection–diffusion models for interacting species
Download2022-06-13
Valeria Giunta, Thomas Hillen, Mark A. Lewis, Jonathan R. Potts
Deriving emergent patterns from models of biological processes is a core concern of mathematical biology. In the context of partial differential equations, these emergent patterns sometimes appear as local minimisers of a corresponding energy functional. Here we give methods for determining the...

Detecting seasonal episodic-like spatiotemporal memory patterns using animal movement modelling
Download2021-01-01
Peter R. Thompson, Andrew E. Derocher, Mark A. Edwards, Mark A. Lewis
Spatial memory plays a role in the way animals perceive their environments, resulting in memory-informed movement patterns that are observable to ecologists. Developing mathematical techniques to understand how animals use memory in their environments allows for an increased understanding of...

Density-dependent constraints on parasite growth, survival or reproduction are thought to be important in preventing the unchecked increase in parasite numbers within individual hosts or host populations. While it is important to know where, and with what severity, density dependence is acting...

Developing techniques for monitoring forest tent caterpillar populations using synthetic pheromones
Download2003
Abstract: To effectively monitor forest tent caterpillar, Malacosoma disstria Hubner (Lepidoptera: Lasiocampidae), populations using sex pheromone baited traps, we field-tested pheromone dispenser (lure) type, lure age, and trap design using (Z,E)-5,7-dodecadienal:(Z,Z)-5,7-dodecadienal (100:1)....

Developmental Basis of an Anatomical Novelty: Heteroarthrocarpy in Cakile lanceolata and Erucaria erucarioides (Brassicaceae)
Download2006
Donohue, K., Tisdale, T.E., Kramer, E.M., Hall, J.C.
To understand the developmental basis of a novel anatomical feature, we present a comparative developmental study of an ecologically significant novelty in fruit morphology. Most members of the tribe Brassiceae have heteroarthrocarpic fruits, in contrast to the unsegmented fruits of many...

Diet and Growth of Northern Pike in the Absence of Prey Fishes: Initial Consequences for Persisting in Disturbance-Prone Lakes.
Download2006
Venturelli, P. A., Tonn, W. M.
The northern pike Esox lucius is a renowned piscivore, but will prey opportunistically on invertebrates (e.g., in small lakes of boreal Alberta, where winterkill can unexpectedly reduce or eliminate prey fishes). We emulated such a disturbance by stocking a fishless lake with northern pike and...
