Climate change winner in the deep sea? Predicting the impacts of climate change on the distribution of the glass sponge Vazella pourtalesii
Beazley, Lindsay; Kenchington, Ellen; Murillo, Francisco Javier; Brickman, David; Wang, Zeliang; Davies, Andrew; Roberts, Emyr Martyn; Rapp, Hans Tore (Journal article; Peer reviewed, 2021)Shallow-water sponges are often cited as being ‘climate change winners’ due to their resiliency against climate change effects compared to other benthic taxa. However, little is known of the impacts of climate change on ... -
Glass sponge grounds on the Scotian Shelf and their associated biodiversity
Hawkes, Nickolas James; Korabik, Michelle; Beazley, Lindsay; Rapp, Hans Tore; Xavier, Joana R.; Kenchington, Ellen (Peer reviewed; Journal article, 2019)Emerald Basin on the Scotian Shelf off Nova Scotia, Canada, is home to a globally unique population of the glass sponge Vazella pourtalesi. Through the analysis of both in situ photographs and trawl catch data from annual ... -
The Hexactinellid Deep-Water Sponge Vazella pourtalesii (Schmidt, 1870) (Rossellidae) Copes With Temporarily Elevated Concentrations of Suspended Natural Sediment
Wurz, Erik; Beazley, Lindsay; MacDonald, Barry; Kenchington, Ellen; Rapp, Hans Tore; Osinga, Ronald (Journal article; Peer reviewed, 2021)Plumes of re-suspended sediment potentially smother and clog the aquiferous system of filter-feeding sponges with unknown implications for their health. For the first time, we examined the physiological responses of repeated ... -
Mapping benthic ecological diversity and interactions with bottom-contact fishing on the Flemish Cap (northwest Atlantic)
Murillo, Francisco Javier; Kenchington, Ellen; Koen-Alonso, Mariano; Guijarro, J.; Kenchington, T.J.; Sacau, M.; Beazley, Lindsay; Rapp, Hans Tore (Journal article; Peer reviewed, 2020)The ecological diversity of benthic invertebrates from bottom trawl surveys was mapped for the Flemish Cap, a plateau of ~200 km radius in the northwest Atlantic. Species density (SpD), the exponential Shannon diversity ... -
A Microbial Nitrogen Engine Modulated by Bacteriosyncytia in Hexactinellid Sponges: Ecological Implications for Deep-Sea Communities
Maldonado, Manuel; López-Acosta, María; Busch, Kathrin; Slaby, Beate M.; Bayer, Kristina; Beazley, Lindsay; Hentschel, Ute; Kenchington, Ellen; Rapp, Hans Tore (Journal article; Peer reviewed, 2021-03-17)Hexactinellid sponges are common in the deep sea, but their functional integration into those ecosystems remains poorly understood. The phylogenetically related species Schaudinnia rosea and Vazella pourtalesii were herein ... -
Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf
Hanz, Ulrike; Beazley, Lindsay; Kenchington, Ellen; Duineveld, Gerard; Rapp, Hans Tore; Mienis, Furu (Journal article; Peer reviewed, 2021)The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in ...
