To Follow in Their Footsteps
When the First Crusade ended with the conquest of Jerusalem in 1099, jubilant crusaders returned home to Europe bringing with them stories, sacred relics, and other memorabilia, including banners, jewelry, and weapons. In the ensuing decades, the memory of the crusaders' bravery and pious sacrifice was invoked widely among the noble families of western Christendom. Popes preaching future crusades would count on these very same families for financing, leadership, and for the willing warriors who would lay down their lives on the battlefield. Despite the great risks and financial hardships associated with crusading, descendants of those who suffered and died on crusade would continue to take the cross, in some cases over several generations. Indeed, as Nicholas L. Paul reveals inTo Follow in Their Footsteps, crusading was very much a family affair.
Scholars of the crusades have long pointed to the importance of dynastic tradition and ties of kinship in the crusading movement but have failed to address more fundamental questions about the operation of these social processes. What is a \"family tradition\"? How are such traditions constructed and maintained, and by whom? How did crusading families confront the loss of their kin in distant lands? Making creative use of Latin dynastic narratives as well as vernacular literature, personal possessions and art objects, and architecture from across western Europe, Paul shows how traditions of crusading were established and reinforced in the collective memories of noble families throughout the twelfth and thirteenth centuries. Even rulers who never fulfilled crusading vows found their political lives dominated and, in some ways, directed by the memory of their crusading ancestors. Filled with unique insights and careful analysis,To Follow in Their Footstepsreveals the lasting impact of the crusades, beyond the expeditions themselves, on the formation of dynastic identity and the culture of the medieval European nobility.

Effects of Marine and Freshwater Macroalgae on In Vitro Total Gas and Methane Production
This study aimed to evaluate the effects of twenty species of tropical macroalgae on in vitro fermentation parameters, total gas production (TGP) and methane (CH4) production when incubated in rumen fluid from cattle fed a low quality roughage diet. Primary biochemical parameters of macroalgae were characterized and included proximate, elemental, and fatty acid (FAME) analysis. Macroalgae and the control, decorticated cottonseed meal (DCS), were incubated in vitro for 72 h, where gas production was continuously monitored. Post-fermentation parameters, including CH4 production, pH, ammonia, apparent organic matter degradability (OMd), and volatile fatty acid (VFA) concentrations were measured. All species of macroalgae had lower TGP and CH4 production than DCS. Dictyota and Asparagopsis had the strongest effects, inhibiting TGP by 53.2% and 61.8%, and CH4 production by 92.2% and 98.9% after 72 h, respectively. Both species also resulted in the lowest total VFA concentration, and the highest molar concentration of propionate among all species analysed, indicating that anaerobic fermentation was affected. Overall, there were no strong relationships between TGP or CH4 production and the >70 biochemical parameters analysed. However, zinc concentrations >0.10 g x kg(-1) may potentially interact with other biochemical components to influence TGP and CH4 production. The lack of relationship between the primary biochemistry of species and gas parameters suggests that significant decreases in TGP and CH4 production are associated with secondary metabolites produced by effective macroalgae. The most effective species, Asparagopsis, offers the most promising alternative for mitigation of enteric CH4 emissions.

Algal Bioremediation of Waste Waters from Land-Based Aquaculture Using Ulva: Selecting Target Species and Strains
The optimised reduction of dissolved nutrient loads in aquaculture effluents through bioremediation requires selection of appropriate algal species and strains. The objective of the current study was to identify target species and strains from the macroalgal genus Ulva for bioremediation of land-based aquaculture facilities in Eastern Australia. We surveyed land-based aquaculture facilities and natural coastal environments across three geographic locations in Eastern Australia to determine which species of Ulva occur naturally in this region and conducted growth trials at three temperature treatments on a subset of samples from each location to determine whether local strains had superior performance under local environmental conditions. DNA barcoding using the markers ITS and tufA identified six species of Ulva, with U. ohnoi being the most common blade species and U. sp. 3 the most common filamentous species. Both species occurred at multiple land-based aquaculture facilities in Townsville and Brisbane and multiple strains of each species grew well in culture. Specific growth rates of U. ohnoi and U. sp. 3 were high (over 9% and 15% day(-1) respectively) across temperature treatments. Within species, strains of U. ohnoi had higher growth in temperatures corresponding to local conditions, suggesting that strains may be locally adapted. However, across all temperature treatments Townsville strains had the highest growth rates (11.2-20.4% day(-1)) and Sydney strains had the lowest growth rates (2.5-8.3% day(-1)). We also found significant differences in growth between strains of U. ohnoi collected from the same geographic location, highlighting the potential to isolate and cultivate fast growing strains. In contrast, there was no clearly identifiable competitive strain of filamentous Ulva, with multiple species and strains having variable performance. The fast growth rates and broad geographical distribution of U. ohnoi make this an ideal species to target for bioremediation activities at land-based aquaculture facilities in Eastern Australia.

The Seeding and Cultivation of a Tropical Species of Filamentous Ulva for Algal Biomass Production
Filamentous species of Ulva are ideal for cultivation because they are robust with high growth rates and maintained across a broad range of environments. Temperate species of filamentous Ulva are commercially cultivated on nets which can be artificially 'seeded' under controlled conditions allowing for a high level of control over seeding density and consequently biomass production. This study quantified for the first time the seeding and culture cycle of a tropical species of filamentous Ulva (Ulva sp. 3) and identified seeding density and nursery period as key factors affecting growth and biomass yield. A seeding density of 621,000 swarmers m(-1) rope in combination with a nursery period of five days resulted in the highest growth rate and correspondingly the highest biomass yield. A nursery period of five days was optimal with up to six times the biomass yield compared to ropes under either shorter or longer nursery periods. These combined parameters of seeding density and nursery period resulted in a specific growth rate of more than 65% day(-1) between 7 and 10 days of outdoor cultivation post-nursery. This was followed by a decrease in growth through to 25 days. This study also demonstrated that the timing of harvest is critical as the maximum biomass yield of 23.0 ± 8.8 g dry weight m(-1) (228.7 ± 115.4 g fresh weight m(-1)) was achieved after 13 days of outdoor cultivation whereas biomass degraded to 15.5 ± 7.3 g dry weight m(-1) (120.2 ± 71.8 g fresh weight m(-1)) over a longer outdoor cultivation period of 25 days. Artificially seeded ropes of Ulva with high biomass yields over short culture cycles may therefore be an alternative to unattached cultivation in integrated pond-based aquaculture systems.

Whose Middle Ages? : teachable moments for an ill-used past
\"Whose Middle Ages? is an interdisciplinary collection of short, accessible essays intended for the nonspecialist reader and ideal for teaching at an undergraduate level. Each of twenty-two essays takes up an area where digging for meaning in the medieval past has brought something distorted back into the present: in our popular entertainment; in our news, our politics, and our propaganda; and in subtler ways that inform how we think about our histories, our countries, and ourselves. Each author looks to a history that has refused to remain past and uses the tools of the academy to read and re-read familiar stories, objects, symbols, and myths\"-- Provided by publisher.

The protein content of seaweeds: a universal nitrogen-to-protein conversion factor of five
A global drive to source additional and sustainable biomass for the production of protein has resulted in a renewed interest in the protein content of seaweeds. However, to determine accurately the potential of seaweeds as a source of protein requires reliable quantitative methods. This article systematically analysed the literature to assess the approaches and methods of protein determination and to provide an evidence-based conversion factor for nitrogen to protein that is specific to seaweeds. Almost 95 % of studies on seaweeds determined protein either by direct extraction procedures (42 % of all studies) or by applying an indirect nitrogen-to-protein conversion factor of 6.25 (52 % of all studies), with the latter as the most widely used method in the last 6 years. Meta-analysis of the true protein content, defined as the sum of the proteomic amino acids, demonstrated that direct extraction procedures underestimated protein content by 33 %, while the most commonly used indirect nitrogen-to-protein conversion factor of 6.25 over-estimated protein content by 43 %. We therefore determined whether a single nitrogen-to-protein conversion factor could be used for seaweeds and evaluated how robust this would be by analysing the variation in this factor for 103 species across 44 studies that span three phyla, multiple geographic regions and a range of nitrogen contents. An overall median nitrogen-to-protein conversion factor of 4.97 was established and an overall mean nitrogen-to-protein conversion factor of 4.76. We propose that the overall median value of 5 be used as the most accurate universal seaweed nitrogen-to-protein (SNP) conversion factor.
