Climate and Demography Dictate the Strength of Predator-Prey Overlap in a Subarctic Marine Ecosystem

Creator:: Hunsicker, Mary E., Ciannelli, Lorenzo, Bailey, Kevin M., Zador, Stephani, and Stige, Leif Christian
Abstract:: There is growing evidence that climate and anthropogenic influences on marine ecosystems are largely manifested by changes in species spatial dynamics. However, less is known about how shifts in species distributions might alter predator-prey overlap and the dynamics of prey populations. We developed a general approach to quantify species spatial...

The effect of climate variation on agro-pastoral production in Africa

Creator:: Stige, Leif Christian, Stave, Jørn, Chan, Kung-Sik, Ciannelli, Lorenzo, Pettorelli, Nathalie, Glantz, Michael, Herren, Hans R., and Stenseth, Nils Chr.
Abstract:: Using national crop and livestock production records from 1961–2003 and satellite-derived data on pasture greenness from 1982–2003 we show that the productivity of crops, livestock, and pastures in Africa is predictably associated with the El Niño Southern Oscillation and the North Atlantic Oscillation. The causal relations of these results are...

Predicting fish recruitment from juvenile abundance and environmental indices

Creator:: Stige, Leif Christian, Hunsicker, Mary E., Bailey, Kevin M., Yaragina, Natalia A., and Hunt, George L., Jr.
Abstract:: Prediction of year-class strength is a critical challenge for fisheries managers. Theoretically, predictions of recruitment should be better when they are based on estimates of cohort size taken close to the age of recruitment and may improve if the effects of environmental factors that influence pre-recruit mortality are accounted for....

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

Modelling dendritic ecological networks in space: an integrated network perspective

Creator:: Peterson, Erin E., Ver Hoef, Jay M., Isaak, Dan J., Falke, Jeffrey A., Fortin, Marie-Jos ee, Jordan, Chris E., McNyset, Kristina, Monestiez, Pascal, Ruesch, Aaron S., Sengupta, Aritra, Som, Nicholas, Steel, E. Ashley, Theobald, David M., Torgersen, Christian E., and Wenger, Seth J.
Abstract:: Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...

Population growth across heterogeneous environments: effects of harvesting and age structure

Creator:: Durant, Joel M., Hidalgo, Manuel, Rouyer, Tristan, Hjermann, Dag O., Ciannelli, Lorenzo, Eikeset, Anne Maria, Yaragina, Natalia, and Stenseth, N. C.
Abstract:: Population growth is affected by several factors such as climate, species interaction and harvesting pressure. However, additional complexity can arise if fishing increases the sensitivity to environmental variability. To predict the effects of fisheries and climate on marine populations, there is a need for improved understanding of how they affect...

Russian and Baltic states fishery developments

Creator:: Shriver, Ann
Abstract:: While accurate information about developments in the fisheries of the former USSR is somewhat difficult to obtain, certain trends have been remarked on by Russian, Baltic State[1], and international observers, and some data is available to support them. The objective of this research is to collect, assess, crosscheck, analyze, and...

Understanding Software-2.0: A Study of Machine Learning library usage and evolution

Creator:: Dilhara, Malinda, Ketkar, Ameya, and Dig, Danny
Abstract:: Enabled by a rich ecosystem of Machine Learning (ML) libraries, programming using learned models, i.e., Software-2.0, has gained substantial adoption. However, we do not know what challenges developers encounter when they use ML libraries. With this knowledge gap, researchers miss opportunities to contribute to new research directions, tool builders do...
