Article Synopsis
- The spread of invasive species, such as the red swamp crayfish, is linked to their reproductive success and population dynamics, making them hard to control.
- A study developed a SNP panel to genotype 1800 individuals in southeastern Michigan, revealing important genetic information about their mating system and reproductive success.
- Findings show a common occurrence of multiple paternity in crayfish populations, emphasizing the need for advanced genomic tools to monitor their population responses and improve control strategies.
Article Synopsis
- The Landscape Theory of Food Web Architecture (LTFWA) explores how body size, trophic position, and energy channels interconnect in diverse habitats to maintain system stability, but evidence has been inconsistent across different ecosystems.
- In a study of the Lake Michigan food web, researchers found a positive correlation between body size and trophic position, with variations based on whether species were supported by pelagic or benthic energy sources.
- The findings indicated that while native top predators contribute to food web stability by connecting energy pathways, introduced species may disrupt this structure, highlighting the complex impacts of human activity on ecosystem dynamics.
The decision to remove or repair a dam depends on multiple variables, many of which encompass both physical and social factors. In Wisconsin, the Department of Natural Resources is mandated to inspect small dams every ten years. A safety inspection often acts as a trigger event to a dam removal or repair decision.
