Hohokam canals as multi-use facilities: Pre-historic canal system in the central Arizona-Phoenix metropolitan area
This is the digitized version of a map of the Hohokam canal system in what is now the Phoenix metropolitan area. It is based on the thesis research by J. B. Howard (Howard, J. (1990). Paleohydraulics : techniques for modeling the operation and growth of prehistoric canal systems. Thesis (M.A.)--Arizona State University, 1990). The original paper map is based on previous archaeological data, overlayed onto USGS 7.5 minute quadrangle maps to recreate the canal pattern.

Ocean multi-use scientific literature bibliographies
<p>Bibtex files listing and describing scientific publications dealing with ocean multi-use and multiple uses published until the end of 2020. The file called "2O210209_Scopus_final_KWclean.bib" is a collection of publications dealing with multi-use in its broader sense while the file named "20210209_Scopus_final_short_KWclean.bib" is a selection of publications refering to multi-use in its narrower sense (i.e. synergistic combinations of human activities at sea). </p> <p>Both file are the result of the following process:</p> <p>The bibliographic search was performed on Scopus on publications’ title, abstract and keywords as follows: “multi-use” OR “multiple uses” OR “multifunctional use” OR “co-use” AND “ocean” OR “sea” OR “marine” OR “maritime” OR “coastal”. Filters were used to exclude conference papers, notes and non-classified publications. This query returned 1 700 distinct documents published between 1970 and 2020. After individually reviewing each one, 1 389 publications were purged from the corpus because they were exclusively focused on the terrestrial realm, dealing with other topics than human activities at sea or approaching marine uses separately.</p> <p>Once these steps were completed, the corpus contained 311 references, including 278 journal papers and 33 book chapters. Some papers published before 2010 and others dealing with <em>pescatourism</em> were not captured by Scopus since they did not explicitly refer to MU or its synonyms. In the first case, the authors mentioned in the title, the abstract or the keywords the uses combined instead of multi-use and, in the second one, they do not always label their research with this term. In spite of these limitations, the corpus was larger and more diverse than expected. The papers dealing with the European conception of multi-use were embedded in a large number of publications mainly related to Marine Protected Areas (MPAs) and secondarily to Marine Spatial Planning (MSP). In fact, protected perimeters allowing human activities such as fishing or tourism, as well as marine spaces covered by planning processes are often described as “multiple uses” and even “multi-use” territories. Schupp et al. already mentioned that ocean multi-use was linked to the management model inspired by the Great Barrier Reef Marine Park zoning experience, but they did not explain how these two objects of study were connected. This relationship deserves special attention since MU, MPAs and MSP address, albeit quite differently, the same problem: the long-term co-existence of intensifying and diversifying activities at sea. Thus, it was decided to extract the 68 papers related to the European conception of multi-use to compare this sub-corpus to the main one. The first one is referred as the short collection and to the second one as the large collection.</p>
Supporting live data sessions in multi-user virtual reality using CAVA360VR
<p>A dense composite 2D video clip showing the different screens and audio chat of three analysts using <em>CAVA360VR </em>(Collaborate, Annotate, Visualise, Analysis 360 video in Virtual Reality) to hold a live virtual data session at a national research conference in 2019. The three co-analysts (M, J and P) in VR were collaborating even though they were in three different physical locations across two countries. The video data that they analysed together involved multicam recordings of six participants in a two-team competition to solve a Lego puzzle when only one member in each group could view the hidden Lego construction in order to instruct the others in their team how to rebuild it from a pile of blocks. The video clip shows the viewport chosen by each of the three analysts. There are three possible viewports that can be selected: a) what they each see in their VR HMD (head-mounted display), b) an over-the-shoulder view (with an outline showing their avatar), and c) a static third-person view of the three analysts. A fourth screen shows the view of an observer in non-VR mode.</p>
Coexistence from a lion's perspective: Movements and habitat selection by African lions (Panthera leo) across a multi-use landscape
<p>Diminishing wild space and population fragmentation are key drivers of large carnivore declines worldwide. Persistence of large carnivores in fragmented landscapes often depends on the ability of individuals to move between separated subpopulations for genetic exchange and recovery from stochastic events. Where separated by anthropogenic landscapes, subpopulations' connectivity hinges on the area's socio-ecological conditions for coexistence and dispersing individuals' behavioral choices. Using GPS-collars and resource- and step-selection functions, we explored African lion (<em>Panthera leo</em>) habitat selection and movement patterns to better understand lions' behavioral adaptations in a landscape shared with pastoralists. We conducted our study in the Ngorongoro Conservation Area, Tanzania, a multiuse rangeland, that connects the small, high density lion subpopulation of the Ngorongoro Crater with the extensive Serengeti lion population. Landscape use by pastoralists and their livestock varies seasonally, driven by the availability of pasture, water, and disease avoidance. The most important factor for lion habitat selection was the amount of vegetation cover, followed by the distance to human settlements and the interaction between those two variables, with selectivity strengths varying with season and time of day. All lions were more willing to approach human settlements at night and during the dry season, selecting strongly for cover when moving closer to humans during the day. Resident females most consistently used areas close to humans, but also relied more consistently on cover than males. Connectivity of lion subpopulations, facilitated by nomadic males, does not appear to be blocked by sparse pastoralist settlements and nomadic males avoided humans on the landscape more strongly than did resident lions. These results are consistent with lions balancing risk from humans with exploitation of livestock by altering their behaviors to reduce potential conflict. Our study lends some optimism for the adaptive capacity of lions to promote coexistence with humans in shared landscapes.</p>

Reintroduced wolves and hunting limit the abundance of a subordinate apex predator in a multi-use landscape
Top-down effects exhibited by apex predators are modulated by human impacts on community composition and species abundances. For these reasons, research supporting strong top-down effects of apex predators occurs almost entirely within protected areas rather than the much more common multi-use landscapes dominating modern ecosystems. Based on 16 years of monitoring, we developed an integrated population model to disentangle the concurrent contributions of a reintroduced apex predator, the gray wolf, human hunting, and prey abundances on vital rates and abundance of a subordinate apex predator, the puma. Increasing wolf numbers had strong negative effects on puma fecundity, and subadult and adult survival. Puma survival was also influenced by density-dependence. Overall, our results showed that puma dynamics in our multi-use landscape were more strongly influenced by top-down forces exhibited by a reintroduced apex predator, than by human hunting or bottom-up forces (prey abundance) subsidized by human activities. Quantitatively, the average annual impact of human hunting on equilibrium puma abundance was approximately equivalent to the effects of 20 wolves. Based on these results, wolves may have limited pumas across North America historically, and dictated puma scarcity in systems lacking sufficient refugia to mitigate the effects of competition.
Livestock grazing is associated with seasonal reduction in pollinator biodiversity and functional dispersion but cheatgrass invasion is not: variation in bee assemblages in a multi-use shortgrass prairie
<p>Livestock grazing and non-native plant species affect rangeland habitats globally. These factors may have important effects on ecosystem services including pollination, yet, interactions between pollinators, grazing, and invasive plants are poorly understood. To address this, we tested the hypothesis that cattle grazing and site colonization by cheatgrass (Bromus tectorum) impact bee foraging and nesting habitats, and the biodiversity of wild bee communities, in a shortgrass prairie system. Bee nesting habitats (litter and wood cover) were marginally improved in non-grazed sites with low cheatgrass cover, though foraging habitat (floral cover and richness, bare soil) did not differ among cattle-grazed sites or non-grazed sites with low or high cheatgrass cover. However, floral cover was a good predictor of bee abundance and functional dispersion. Mean bee abundance, richness, diversity and functional diversity were significantly lower in cattle-grazed habitats than in non-grazed habitats. Differences in bee diversity among habitats were pronounced early in the growing season (May) but by late-season (August) these differences eroded as Melissodes spp. and Bombus spp. became more abundant at study sites. Fourth-corner analysis revealed that sites with high floral cover tended to support large, social, polylectic bees; sites with high grass cover tended to support oligolectic solitary bees. Both cattle-grazed sites and sites with high cheatgrass cover were associated with lower abundances of above-ground nesting bees but higher abundance of below-ground nesters than non-grazed sites with low cheatgrass cover. We conclude that high cheatgrass cover is not associated with reduced bee biodiversity or abundance, but cattle grazing was negatively associated with bee abundances and altered species composition. Although floral cover is an important predictor of bee assemblages, this was not impacted by cattle grazing and our study suggests that cattle likely impact bee communities through effects other than those mediated by forbs, including soil disturbance or nest destruction. Efforts aimed at pollinator conservation in prairie habitats should focus on managing cattle impacts early in the growing season to benefit sensitive bee species.</p>
Data from: Trade-offs in the multi-use potential of managed boreal forests
1. Implementing multi-use forest management to account for both commercial and non-commercial ecosystem services is gaining increased global recognition. Despite its spatial extent, and great economic and ecological values, few studies have evaluated the boreal forest and its management to assess the potential for simultaneous delivery of a suite of ecosystem services. 2. Using data from a Swedish long-term experiment this study explores how biodiversity of the ground vegetation and potential delivery of multiple ecosystem services (timber production, carbon (C) storage and non-timber forest products) are influenced by two common silvicultural practices (thinning, fertilization and their interaction). 3. Diversity (diversity indices and species richness) of the ground vegetation was higher in thinned than in unthinned forest, something partly explained by six species of lichens that only occurred in thinned forest. In addition, supply of lichens for reindeer forage was three times higher in thinned forest. Fertilization negatively affected the lingonberry shrub (Vaccinium vitis-idaea). Timber production increased with fertilization, but decreased with thinning. The potential for C storage was highest in fertilized forests, which, apart from having the highest timber production, also supported the highest standing tree biomass. 4. The silvicultural practices evaluated induced trade-offs among the ecosystem features studied as thinning increased biodiversity of the ground vegetation, production potential of wild berries and lichens, but reduced timber production and the forest's potential for C storage. Fertilization, had the opposite effect, promoting the potential for C storage at the expense of biodiversity and the ecosystem services delivered by the ground vegetation. 5. Synthesis and applications. Silvicultural practice had a pronounced effect on the multi-use output, and trade-offs among values were common. Nevertheless, our study demonstrates that silvicultural practices that are currently adopted in Sweden can be used to adjust the multi-use potential output of forests, suggesting that commonly used practices can be applied to maintain, or even increase the multi-use potential of the boreal forest biome, if management objectives are allowed to vary across the landscape. A prerequisite for this is site specific management objectives that clearly determine the desired output.

Nutrient loading from a sustainably certified aquaculture operation dwarfs annual nutrient inputs from a large multi-use watershed, Lake Yojoa, Honduras (DATA)
<p><strong>Dataset for manuscript entitled: "Nutrient loading from a sustainably certified aquaculture operation dwarfs annual nutrient inputs from a large multi-use watershed, Lake Yojoa, Honduras"</strong></p> <p><strong>Abstract: </strong>Net-pen aquaculture is a popular and increasingly prevalent method for producing large quantities of low-fat protein in freshwater ecosystems across the tropics. While there are numerable social and economic advantages associated with aquaculture, there are also challenges related to the environmental sustainability of aquaculture operations which supply pens with externally produced feed. For example, excessive nutrient loading which can drive rapid eutrophication in aquatic ecosystems is a major risk. In this study we compare the estimated annual nutrient loads from the six principal tributaries that contribute to Lake Yojoa to the estimated nutrient load of a large net-pen Tilapia operation located in the central region of the lake. The Tilapia farm was responsible for ~ 86% of the nitrogen (N) and ~95% of the phosphorus (P) contributions to Lake Yojoa for the year of our study. This disproportionate nutrient loading of both N and P suggests that this single aquaculture operation, more so than changes in nutrient inputs from the watershed, was responsible for the previously documented deterioration of Lake Yojoa. This study shows the potential for net-pen aquaculture to have disproportionately negative impacts on freshwater ecosystems, even when operations meet the current sustainability certifications standards. We suggest shifts in metrics that could improve the impact of the certification process so that best practices can reduce the impact of net-pen aquaculture on freshwater ecosystems and arrive at the intended goal of long-term environmental sustainability.</p> <p>Data files: </p> <ul> <li>rating_curves_2018_2019: Rating cruves for tributaries Helado, Balas, Varsovia, and Raices</li> <li>sensor_2018_2019: Pressure transducer data for Healdo, Balas, Varsovia, and Raices</li> <li>Staff_TS_27MAY21: Manual stage measurements for Helado, Balas, Varsovia, and Raices</li> <li>13OCT21_Rivers: In stream nutrient data for all tributaries</li> <li>q_cacao_2019: Discharge for Cacao calculated using Manning's equation (methods provided in text)</li> <li>q_yure_2019: Discharge for Yure calculated using Manning's equation (methods provided in text)</li> <li>N_P_aqua: Nutrient contributions from aquaculture (calculations provided in Supplemental Text 4)</li> <li>precip: Yojoa watershed precipitation</li> </ul> <p> </p>
