Most migratory birds of the world's flyways are in decline, or in conservation troubles by now. The Old World flyway connecting Western Europe with Africa is no exception and hardly a surprise, while Africa features a tragic colonial legacy serving primarily the 'Global North' and a small group of wealthy or royal actors while the vast majority of people in Africa etc are ignored. Further, this Afro‐Palaearctic flyway is unique in the fact that it features deep science, done for over 100 years, by elite universities, institutions and NGOs. Still, bird numbers in UK, Germany, France, Spain, and Africa overall are in decline already for easily over a decade. It's a crisis of science-based conservation, as practiced by 'The West', in Europe and by Africa and its NGOs and governance. Here I assess a flyway conservation review by Vickery et al (2023) in the context of science bias, reality context, poverty and some ecological economics perspectives for conservation effectiveness. Reference is made to our own work, e.g. Walther and Huettmann (2021) and Chernetsov and Huettmann (2005), as well as to modern conservation practices, development aid and a future outlook involving climate change, modern methods as well as conflicts and warfare centered around resource extraction at avian conservation hotspots in Africa and the flyway.

Urban gulls are a fascinating issue in recent times. Most people in the world now live in cities, where they are confronted with urban governance and its wildlife, such as cockroaches, squirrels, rats, pigeons and gulls, let's say. In the subarctic this issue is widely unstudied but matters equally while most people in the world do live in cities: The Anthropocene. Here I present on a recent study by us on gulls using urban habitat surveys, 'Big Data', GIS, machine learning and its inference (Huettmann et al. 2023). I present that short-billed gulls swap in summer an ecological niche space with ravens, driven by human factors like industrialization, rivers and gravel pits and food subsidies whereas 'natural forests' now get overruled. This work has implications how urban spaces are to be managed due to gulls being known as major disease reservoirs and perceived pests. Thus far, this scheme is poorly addressed while an effective and sustainable municipal management does rule in the absence, with amateur bird watchers and contractors often dominating. An effective urban wildlife management is certainly lacking for most arctic and polar regions where pandemics currently affect such avian populations and subsequently can result into massive population crashes.

When snow gets warmed up it melts; virtually every child will know that.  However, on a policy and public level, those details are hardly acknowledged, certainly not the vast impacts that relate to lacking 'snow pack', e.g. seasonality, regional climate, and feeding water tables, rivers, estuaries and thus directly contributing to farming, global food security and warfare even - to name just a few. Here I share my first-hand experiences across years from observing snow and ice in winter for areas like Hindu Kush-Himalaya, Antarctica and Alaska, the mountains and ice sheet landscapes. Those 'coldspots' are traditionally known for major ice and snow - cooling areas - of the world as indicators of the global temperature. In this podcast I outline how this crucial subject for humanity -driven by man-made CO2 and Greenhouse Gas (GHGs) - received too little attention but hopefully can get addressed better now for future generations.

New Zealand (NZ) is blessed with a unique, quite wild nature and its endemic biodiversity. Also, NZ as a relatively small nation with c. 5.1 mio inhabitants features the world's 4th largest exclusive economic zone (EEZ). But modern NZ also entails many governance problems. Indigenous concepts are becoming now more dominant in NZ, and commercial fisheries there have a governance stronghold. Many of the fisheries products are actually for export, e.g. U.S., Asia and the EU/UK. Like found in many fisheries nations, e.g. Japan, Norway and Iceland, the set up of Marine Protected Areas (MPAs) get widely opposed and marine protected areas make just for s very tiny fraction of the EEZ and its conservation. This podcast elaborates on an article by journalist Andrea Vance (2022) presenting an overview of the MPA process in NZ and specifically for the southeastern coastline -the South East Marine Protection (SEMP) network process initiated already in 2013 - featuring great ecosystems and conservation species like yellow-eyed penguins, royal albatross, dolphins, sea lions and rock lobsters.

Some environmental patterns appear to be local - but upon closer inspection - then have a wider and larger spill-over and are actually driven by global actors. Based on a recent study by Veit et al. (2021) here a seabird example is presented - the Elegant Tern - and how its conservation management effects spill into the wider Pacific and the Atlantic, including western Europe (Spain and France). It turned global. Most individuals of this tern species breed on just one tiny island in southern California - Isla Raza. However, individual bird vagrants of Elegant Terns are found by bird watchers and researchers in areas far away from this source but directly affected by rodent/predator-removal and other factors - most of them man-made and cultural. The concept of telecoupling (=widely connected sources, sinks and spill-overs) can be applied here and it helps in the Anthropocene to understand how global economies, their cultures/attitudes and actions all affect oceans, species, prey and climate alike - including some of the associated El Nino patterns.   References (selection) Liu J., Y.
