Importance of riparian vegetation for water bodies

Riparian area is a transitional semiterrestrial/semiaquatic biome, the interface between land and river or stream extending from the edges of water bodies to the edges of upland regions. This area includes flood plains and landscapes closely surrounding streams, rivers, vernal pools, ephemeral streams, ponds and lakes. Plant habitat along water bodies is riparian vegetation, consisted of hydrophilic …

Fungi in ecosystems

Fungi have existed roughly 5/6 of the earth’s existance. They have had a lot of time to adapt to every environment on earth. For comparison, the humanoid species has existed 0,01 % of earth’s time (from the first speciments of the genus to Homo sapiens). Fungi are everywhere – they are so widespread, they make …

Dolphin series: monitoring dolphins

For the biologist, dolphin research presents challenges and opportunities in trying to understand individual species in their marine ecosystems. Marine mammals are highly mobile, cover large areas, move in three spatial dimensions, and spend most of their lives under water. So for most species of delphinids, basic aspects of their evolution, physiology, ecology, behavior and …

Dolphin series: fishery interactions

Fishing intensity keeps increasing throughout the world, which has negative impacts on nontarget species, including marine mammals. Thus bycatches have become a critical issue for marine mammal populations. Every year fishing industry removes about 80–90 million tons of fish and other marine organisms from the world’s oceans. Another 7–8 million tons of unwanted animal biomass …

Threats to dolphins

Dolphin mortality results from both natural and anthropogenic causes. Natural causes include old age, failure to thrive as a calf, intra-specific agonistic interactions, predation, stingray wounds, disease, storms and biotoxins from harmful algal blooms such as red tides. Threats of human origin include entanglement in nets, entanglement in or ingestion of fishing gear, pollution, boat …

How dolphins communicate

Dolphins keep a complex social network which includes a few close associates (such as mothers and calves or pair-bonded individuals) and some more casual relationships within a larger group. Dolphins hunt together for food, pods coordinate their movements to herd prey. They have a very acute sense of hearing which they use to communicate with …
