Laurier Biology Departmental Seminars Poster Colouring Book (Vol 2), Tristan A.F. Long

Biology Faculty Publications

Welcome to Volume 2 of the Wilfrid Laurier University Department of Biology seminar series poster collection! When I was compiling a colouring book based on academic seminar posters last year, I had no idea how well it would be received. As of this writing, Volume 1 has been downloaded almost 1000 times (!): https://scholars.wlu.ca/biol_faculty/94/, and was featured in a great article by Cheyenne Bholla: https://www.therecord.com/news/waterloo-region/2022/04/27/laurier-biology-profs-science-posters-have-been-turned-into-a-downloadable-colouring-book.html.

So, I guess it’s time for a sequel, featuring some more of my favourite designs! This time round I’ve included several sets of posters – often drawn years apart – that are thematically …

Ancyronyx Jhoanae Sp. Nov. (Coleoptera: Elmidae), A New Spider Riffle Beetle Species From Luzon, Philippines, And New Records For A. Tamaraw Freitag, 2013, Christalle Beatriz N. Seno, Hendrik Freitag

Biology Faculty Publications

Ancyronyx jhoanae sp. nov., a new species of genus Ancyronyx Erichson, 1847 from Luzon is described using an integrative taxonomic approach. Illustrations of habitus and diagnostic characters are provided. Molecular analysis of a fragment of the COI 5’-end was employed to support the morphological species concept. Differences from closely related species based on molecular and morphological data are discussed. First records of A. tamaraw Freitag, 2013 from Luzon are reported.

Laurier Biology Departmental Seminars Poster Colouring Book (Vol 1), Tristan A.F. Long

Biology Faculty Publications

Departmental seminar posters are largely utilitarian affairs – who is talking?, when are they speaking?, where is the seminar? (and maybe will there will be refreshments served?). While functional, they often fail to capture the beauty and excitement of their subject matter, and may fail to engage a wider audience. As the organizer of the Wilfrid Laurier University Department of Biology seminar series in 2014, on a lark, I started drawing posters that tried to illustrate our speaker’s research in a non-conventional manner, and hopefully appeal to those that might otherwise find attending a departmental seminar intimidating. Little did I …

Salicylic Acid And N-Hydroxypipecolic Acid At The Fulcrum Of The Plant Immunity-Growth Equilibrium, Alyssa Shields, Vanessa Shivnauth, Christian Danve M. Castroverde

Biology Faculty Publications

Salicylic acid (SA) and N-hydroxypipecolic acid (NHP) are two central plant immune signals involved in both resistance at local sites of pathogen infection (basal resistance) and at distal uninfected sites after primary infection (systemic acquired resistance). Major discoveries and advances have led to deeper understanding of their biosynthesis and signaling during plant defense responses. In addition to their well-defined roles in immunity, recent research is emerging on their direct mechanistic impacts on plant growth and development. In this review, we will first provide an overview of how SA and NHP regulate local and systemic immune responses in plants. We …

Temperature Regulation Of Plant Hormone Signaling During Stress And Development, Christian Castroverde, Damaris Dina

Biology Faculty Publications

Global climate change has broad-ranging impacts on the natural environment and human civilization. Increasing average temperatures along with more frequent heat waves collectively have negative effects on cultivated crops in agricultural sectors and wild species in natural ecosystems. These aberrantly hot temperatures, together with cold stress, represent major abiotic stresses to plants. Molecular and physiological responses to high and low temperatures are intricately linked to the regulation of important plant hormones. In this review, we shall highlight our current understanding of how changing temperatures regulate plant hormone pathways during immunity, stress responses and development. This article will present an overview …

Fast Shoreline Erosion Induced By Ship Wakes In A Coastal Lagoon: Field Evidence And Remote Sensing Analysis, Luca Zaggia, Giuliano Lorenzetti, Giorgia Manfe, Gian Marco Scarpa, Emanuela Molinaroli, Kevin E. Parnell, John Rapaglia, Maria Gionta, Tarmo Soomere

Biology Faculty Publications

An investigation based on in-situ surveys combined with remote sensing and GIS analysis revealed fast shoreline retreat on the side of a major waterway, the Malamocco Marghera Channel, in the Lagoon of Venice, Italy. Monthly and long-term regression rates caused by ship wakes in a reclaimed industrial area were considered. The short-term analysis, based on field surveys carried out between April 2014 and January 2015, revealed that the speed of shoreline regression was insignificantly dependent on the distance from the navigation channel, but was not constant through time. Periods of high water levels due to tidal forcing or storm surges, …
