Geophysical Prospecting, Volume 73, Issue 9, November 2025.ABSTRACT In Brazil, concerns about marine life have resulted in strong restrictions on seismic operations, with a minimum distance of 60 km between source vessels and an exclusion zone of 1000 m for marine mammals. These restrictions impact survey efficiency, duration, logistics and cost. Optimized and physically smaller seismic sources may reduce cost

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork
Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Global Ecology and Biogeography, Volume 33, Issue 12, December 2024.ABSTRACT Aim Changes in landscape configuration significantly impact ecosystems and the services they provide, including disease regulation for both humans and wildlife. Land use conversion usually favors disturbed‐adapted species, which are often known reservoirs of zoonotic parasites, thereby potentially escalating spillover events (i.e., the ...

Tijdschrift voor Economische en Sociale Geografie, Volume 115, Issue 4, Page 554-570, September 2024.Abstract Developing walkable urban environments is crucial for enhancing urban liveability and sustainability. To evaluate the chrono‐urbanism status, this study combines conventional census and mapping data with social media check‐in big data. A composite index is proposed, which assesses the accessibility of essential urban functions under the 5/10 ...
