Indications of polymorphism in the behaviour and morphology of burbot (Lota lota) in a European lake
AbstractIn this study, polymorphism in behaviour, morphology, and stable isotope signatures of burbot from Lake Southern Konnevesi, Finland, Europe, was examined. First, local knowledge was collected on exceptional polymorphism of the spawning behaviour and morphology of burbot. These phenomena were then studied based on catch samples. Interviews and catch sample analyses suggested two morphs of burbot: one morph spawning in late February in the littoral zone and other in late March, in deep profundal, depths of about 30 m. Fish caught from the profundal zone had higher average proportional somatic body weights and wider heads than those caught from the littoral spawning sites in February. …
Pathways towards a sustainable future envisioned by early-career conservation researchers
Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation continues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization of, actions furthering sustainability. We conducted a survey (n = 67) and an interactive workshop (n = 35) for ECR attendees of the 5th European Congress of Conservation Biology (2018). Building on these data and discussions, we identified ongoing and forthcoming advances in conservation science. These include increased transdisciplinarity, science communication, advocacy in conservati…
Suojeltujen soiden potentiaali luontohaittojen hyvittämisessä on hiipumassa?
Ekologiset kompensaatiot ovat keino, jonka avulla voidaan estää kokonaisheikennyksen syntymistä luonnolle. Kompensaation tarve luonnon monimuotoisuuden köyhtymisen pysäyttämiseksi on tunnistettu kansainvälisesti ja sittemmin myös Suomessa luonnon-suojelulain toimivuusarvioinnissa (kts. hallituksen esityksen luonnos, Valtioneuvosto 2021). Alue ja Ympäristö -lehdessä julkaistu tutkimuksemme ”Ekologisten haittojen hyvittäminen suojelualueita ennallistamalla” (Mustajärvi ym. 2019) tarkasteli jo aiemmin suojeltujen, mutta ihmistoiminnan heikentämien alueiden soveltumista kompensaatiossa tarvittavien luontohyötyjen tuottamiseen. Sen keskeisenä tavoitteena oli selvittää, voidaanko jo aiemmin suoje…
