Mourning as posthuman ethics : interspecies grief and solidarity in extinction plays
Autorzy:
Kamińska, Aleksandra
Opis:
Among the current calls for a redefinition of the Anthropocene as a non-anthropocentric concept, cultural extinction studies offer ways of advancing posthuman ethics through more-than-human practices of mourning. Adapting Judith Butler’s notion of (un)grievability, extinction studies scholars promote cultural practices aimed at recognising the grievability of other-than-human lives. Arguably, one of the media enabling the enactment of interspecies mourning is theatre. Building on the theoretical framework proposed by cultural extinction studies, the article discusses a selection of contemporary plays grouped under the label of “extinction drama,” focusing on the themes of humans’ and other-than-humans’ shared vulnerability to extinction, humanimal temporalities of extinction, and interspecies mourning.

Opis:
In a discrete Lotka-Volterra model, the set of points where a population remains unchanged over one generation is a hyperplane. Examining the relative position of these hyperplanes, we give sufficient conditions for a groupof species to drive another species to extinction. Further using these hyperplanes, we find necessary and sufficient conditions where every w-limit point of the model has at least one species missing. Building on the workof Hofbauer et al. (1987) involving permanence, we obtain a sufficient condition for one or more species to persist. Additionally, in the presence of extinction occurring, we take these persistence results and the previously mentioned extinction results and extend them to subsystems of the full model. Finally, we combine the ideas of persistence and weak extinctionto obtain another extinction result.

Rare species of birds nesting in the area of the Rogów Forest District in the years 1949–2015

Opis:
Przemysław Szmit
The aim of the study was to combine and summarize data on rare species of breeding forest birds found in the area of the Experimental Forest District near the Rogów village (Łódź Province). Our study area comprised 230 km2 of field and forest mosaic, where forests accounted for almost 17% of the area (13 forest complexes of 35 - 1000 ha). The results are based on the authors’ own field observations from the years 2000 - 2015 as well as historical data since 1949 including original research papers, diploma theses, unpublished manuscripts, oral information and analyses of museum collections. The following criteria were used to categorise bird species as rare: (1) species that ceased breeding in the area, (2) taxa that were under strict protection and their abundance was no higher than 6 breeding pairs. In overall, 10 species were classified as rare, of which three do not breed in the area any more: grey heron Ardea cinerea, osprey Pandion haliaetus, European roller Coracias garrulus. However, non-breeding individuals of grey heron and osprey are still recorded in the area (the last cases of breeding pairs were recorded in the 1970s and 1961, respectively), while the European roller went extinct. In recent years, the abundance of another three species was probably stable: European honey buzzard Pernis apivorus, Eurasian hobby Falco subbuteo and nightjar Caprimulgus europaeus. Four species started breeding in the last 30 years: black stork Ciconia nigra, white-tailed eagle Haliaaetus albicilla, common crane Grus grus, stock dove Columba oenas. The trends in the abundance of the investigated species are similar to those observed in the country in overall.

Opis:
Aurochs (Bos primigenius) was a unique species lasting through Pleistocene and Holocene for about two million years. The aurochs was one of the largest animals ever to inhabit Europe. The longest the species survived in the very Central Europe (presently Poland), where in spite of being taken under quite modern protection the last aged cow died in the year 1627. The most often brought up reason for dying out of the Aurochs is hunting and pouching. Another belief is, that growing agriculture pushed them away further from human sites. The study of the ancient DNA is quite a challenge. Although more and more research centers undertake the task, there is still little knowledge on this matter. First step of analysis is finding of certified aurochs bones or teeth and isolation of DNA. That was the most important step, followed by cloning of aurochs DNA in bacterial system for further analysis encompassing DNA sequencing and comparison with the existing bovine database in search for any similarities and specific genes. Some of the results have been already published. Studies of aurochs help also understanding history of species, its relation to other species and perhaps will help preventing extinction of other animals.

Opis:
The herpetofaunal biodiversity of West Indies suffered a significant change during the last few million years that is well documented for some squamate reptilies (lizards). However, almost nothing is known about past biodiversity of snakes, which are active predators and important component of terrestrial ecosystems. Here we describe the fossil remains of snakes (Reptilia: Serpentes) from the late Pleistocene of El Abrón Cave, Cuba. This is the first representative assemblage of fossil snakes from Cuba. It allows us to evaluate the taxonomic diversity of snakes in the Pleistocene of the island for the first time. The material includes eight taxa from the four snake families: cf. Cubatyphlops (Typhlopidae), Tropidophis melanurus, Tropidophis sp., Cubophis cf. cantherigerus, Arrhyton sp., cf. Caraiba andreae, Dipsadidae indet., and Natricidae indet. (Natricidae). Two (Dipsadidae indet. and Natricidae indet.) are not known in the modern fauna of Cuba. The assemblage from El Abrón Cave shows that ophidian Pleistocene assemblage was different from modern snake fauna of Cuba and was probably more diverse at genus level than it is now. Most of taxa revealed in El Abrón Cave were not previously known in the fossil record.

Aktywizm klimatyczny w mediach. Studium przypadku Extinction Rebellion Kraków
Climate activism in the media. Case study of Extinction Rebellion Kraków.
Autorzy:
Smółka, Patryk
Opis:
The article addresses issues of climate disaster information management and communication in the social media of a grassroots activist movement. In order to formulate conclusions and empirically confront the described phenomenon, a case study method was used that included content analysis, observation and an interview with an activist involved in the organisation’s media management. The paper presents the history and description of the activities of the Extinction Rebellion movement, the concept of climate activism in the media, the networking of activist activities and the idea of management in the Anthropocene. This is followed by a description of the state of the research on the organization and of the methodological background of media management and social media management. Next a discussion of different elements and outcomes of the study, as well as a presentation of the conclusions takes place. The paper concludes by presenting the impact of the decentralised movement structure on the effectiveness of XR Krakow’s media activities.
Artykuł porusza kwestie zarządzania informacją o katastrofie klimatycznej i komunikacji oddolnego ruchu aktywistycznego w mediach społecznościowych. W celu sformułowania wniosków i empirycznej konfrontacji z opisywanym zjawiskiem zastosowano metodę studium przypadku obejmującą analizę treści, obserwację i wywiad z osobą aktywistyczną zaangażowaną w zarządzanie mediami organizacji. W artykule przedstawiono historię i opis działalności ruchu Extinction Rebellion, koncepcję aktywizmu klimatycznego w mediach, usieciowienie działań aktywistycznych oraz ideę zarządzania w antropocenie. W dalszej części opisano stan badań nad organizacją oraz metodologiczne podłoże zarządzania mediami i zarządzania mediami społecznościowymi, po czym omówiono poszczególne elementy i wyniki badania oraz przedstawiono wnioski. W konkluzji pracy przedyskutowano wpływ zdecentralizowanej struktury ruchu na skuteczność działalności XR Kraków w mediach.
