Biogeography and Ecological Diversification of a Mayfly Clade in New Guinea

Frontiers in Ecology and Evolution, 2019
Understanding processes that have driven the extraordinary high level of biodiversity in the tropics is a long-standing question in biology. Here we try to assess whether the large lineage richness found in a New Guinean clade of mayflies (Ephemeroptera),

Catchment conversion to agriculture alters freshwater macroinvertebrate community responses to flow disturbance: results from a replicated in‐stream experiment

Oikos, Volume 2026, Issue 7, July 2026.
Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Unveiling the Global Linnean Shortfall in Leptophlebiidae (Ephemeroptera, Insecta): Historical Trends and Conservation Implications

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT Understanding how many species exist on Earth is a fundamental yet challenging question in biology, with significant implications for biodiversity conservation. The Linnean shortfall, or the gap in taxonomic knowledge, remains a major obstacle, particularly in highly diverse groups like insects. This study focuses on the family Leptophlebiidae
