The Biofilm grazer model is an agent based model (ABM) built upon the MESA ABM framework ( https://mesa.readthedocs.io/en/stable/ ). The model helps us understand the effects of nutrient, light and grazing on the spatio-temporal development of rivernine biofilm. Instructions from the README.md will help you set up the environment and run the model.

In this letter, we introduce The Polar Vocabularies and Semantics Working Group, originally established as a joint effort between the joint SAON/IASC Arctic Data Committee and the Data Management Collaboration Team of the Interagency Arctic Research Policy Committee. We Invite, communities of practice to actively engage with us in our activities (described below), to advance the state of semantics-based applications in polar activities (and to increase interoperability between stakeholders and rights holders within existing and emerging digital ecosystems).

A Bayesian network-based, user-friendly decision support tool modelling how different socioeconomic factors affect the effectiveness of a marine protected area. This is the model included in the paper "Socio-economic factors boosting the effectiveness of marine protected areas: a Bayesian network analysis".

Cross-basin and cross-taxa patterns of marine community tropicalization and deborealization in warming European seas. Nature Communications Please check the github repo cti_cross_region_taxon for updates. Abstract Ocean warming and acidification, decreases in dissolved oxygen concentrations, and changes in primary production are causing an unprecedented global redistribution of marine life. The identification of underlying ecological processes underpinning marine species turnover, particularly the prevalence of tropicalization over deborealization, has been recently debated in the context of ocean warming. Here, we track changes in the mean thermal affinity of marine communities across European seas by calculating the Community Temperature Index for 65 biodiversity time series collected over four decades and containing 1,817 species from different communities (zooplankton, coastal benthos, pelagic and demersal invertebrates and fish). We show most communities and sites have clearly responded to ongoing ocean warming via abundance increases of warm-water species (tropicalization; 54%) and decreases of cold-water species (deborealization; 18%). Tropicalization dominated Atlantic sites compared to semi-enclosed basins such as the Mediterranean and Baltic Seas, probably due to physical barrier constraints to connectivity and species colonization. Semi-enclosed basins appeared to be particularly vulnerable to ocean warming, experiencing the fastest rates of warming and biodiversity loss through deborealization. Keywords: climate change, community temperature index, CTI, ocean connectivity.

Sub-acute ruminal acidosis (SARA), a disorder characterized by chronic low ruminal pH, occurs in feedlot cattle fed high-concentrate diets. Forages slow digestion and reduce acid production. Thus, we aimed to assess how motivated finishing cattle are to access forage (Sudan grass hay, SG) via their willingness to interact with an electrified barrier. Reticulorumen pH was measured to contextualize the results with digestive health. Twenty-eight animals fed a high-concentrate ration ad-libitum had access to 4 L one of two treatments (n=14/treatment) fed once a day behind a barrier: 1) SG, or 2) an additional offering of the normal ration (TMR). To access a treatment, the steer voluntarily pushed his muzzle against an electrified barrier. The electrical current was increased exponentially every 24 h (0, 156, 312, 625, 1250, 2500, 5000 µA) until the animal ceased accessing it. Visits to the treatment were recorded continuously 24 h/d and reticulorumen pH was measured every 10 min. Rumen pH averaged 3.0±1.2 and 2.3±0.9 h/d below 5.6, for SG and TMR, respectively, meeting the criterion for SARA. However, animals with access to SG were less likely to advance to the next current than TMR animals (P<0.01) and were approximately 3x less willing to interact with higher currents than TMR (mean maximum current touched: 469±169 and 1380±254 mA, respectively, mean±SE, P=0.01). Lower motivation to access SG was further demonstrated through fewer visits to the SG (2.4±0.4 vs 5.3±0.6 #/d, P<0.01), and less SG consumed than TMR (32.0±0.1 vs 74.0±0.0 %/d, P<0.01). Overall, finishing cattle valued the TMR more than SG, likely because of differences in the quantity offered, palatability, and familiarity. When rumen health was considered, SG animals visited more often (r=0.5, P=0.09) and showed fewer failed attempts (r=-0.5, P=0.06) to access forage as the severity and duration of pH depression below 5.6, for example, increased. There was no relationship between any measure of treatment use and pH depression for TMR animals (P≥0.3). These findings provide evidence that cattle are motivated for Sudan grass hay when experiencing chronic low reticulorumen pH. However, the findings also contribute to the mixed evidence about motivation for forage in this life stage, because, overall TMR was valued more highly than SG. Indeed, despite widespread pH depression, TMR cattle contrafreeloaded for additional concentrate, demonstrating unexpectedly high motivation for this resource.

The Swiss Federal Food Safety and Veterinary Office (FSVO) is providing a report intended to serve as a basis for discussion on the impact of mercury released from permafrost on Switzerland’s food safety. In order to identify the relevant fish that might indicate the mercury exposure of the Swiss population and to monitor possible changes in the situation in the coming years, the data available in the scientific literature and databases were reviewed. It covers only certain aspects of data interpretation and does not claim to be comprehensive. CH;PDF;efsafocalpoint@blv.admin.ch
