This paper outlines the fieldwork methods utilized by ecologists in (re)presenting wolves in Romania. By revealing the processes and performances of this aspect of wildlife conservation, the paper highlights the complex more-than-human assemblages that make up wolf ecology. It briefly discusses the ways HAS (Human-Animal Studies) and the social sciences have addressed conservation and unpacked the oft obscured hinterland of bodies and technologies. It then blends field stories and ethnographic narrative to emphasize the multi-sensory techniques employed in non-invasive wolf research. By using this novel case, the paper contextualizes the significance of concepts such as becoming, affect, and attunement in creating partial affinities between researchers and wildlife. It argues that these contribute to an emplaced knowledge that allows practices to adapt to contingencies in field. This is important when modern, remote technologies aimed at minimizing effort in the field are seen to be a panacea for monitoring elusive wildlife.

By considering the emergence and threat of African Swine Fever (ASF) in Europe, this paper demonstrates the growing role of veterinary rationales in reframing contemporary human-wild boar coexistence. Through comparative ethnographies of human-wild boar relations in the Czech Republic, Spain and England, it shows that coexistence is not a predictable and steady process but is also demarked by points of radical change in form, course and atmosphere. Such moments, or wild boar events, can lead to the (re-)formation or magnified influence of certain discourses, practices and power relations in determining strategies of bio-governance. Specifically, this paper highlights how the spread of ASF in Europe has accelerated an already ongoing process of veterinarization, understood as the growing prominence of veterinary sciences in the mediation and reorganization of contemporary socioecologies. This example highlights how veterinary logics increasingly influence localized human-wildlife relations and, through analogous practices of biosecurity and control, also connect different places and geographic contexts.

Effects were investigated of PO,-P limitation and climate on natural assemblages of marine diatoms grown in outdoor semicontinuous cultures. The cultures were grown at 3 dilution rates (1.7; 0.851; 0.32 doublings d-l) throughout the year. Temperature dependent maximum growth rate of cultures was predicted by the Eppley equation. Nutrient limitation measured as N : P and Si : P cellular ratios increased with decreasing dilution rate or increasing temperature in a manner analogous to that in single-species cultures studied by other workers. However, species dominance changed with changing nutrient stress. Skeletonema costatum was dominant at high dilution rates; it was replaced by Chaetoceros spp. and then Cylindrotheca closterjum at lower dilution rates. Thalassiosira spp. COexisted with S. costatum or Chaetoceros spp. at low light intensities and temperatures. It is concluded that multi-species cultures adapt to nutrient stress by species replacement rather than physiological adaptation of a single species.
