Facilitation of benthic assemblages by Bluehead Chubs: Testing the stress‐gradient hypothesis in streams

open access: yesEcology of Freshwater Fish, Volume 33, Issue 2, April 2024.
Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

Escaping malnutrition by shifting habitats: A driver of three‐spined stickleback invasion in Lake Constance

open access: yesJournal of Fish Biology, Volume 104, Issue 3, Page 746-757, March 2024.
Abstract Fatty acids, and especially long‐chain polyunsaturated fatty acids, are biologically important components in the metabolism of vertebrates, including fish. Essential fatty acids (EFA) are those that in a given animal cannot be synthesized or modified from precursors and must therefore be acquired via the diet.

Assessing the Effects of Parasitism and Predation by Water Mites on the Mosquitoes

open access: yesTrends in Computational and Applied Mathematics, 2007
Water mites (Hydrachnidia) are a group of arthropods with a complex life cycle which includes larval and three nymphal stages. The mite larvae parasitize aquatic and semiaquatic insects, while deutonymphs and adult mites are predators of insect larvae ...

Mediterranean springs: Keystone ecosystems and biodiversity refugia threatened by global change

open access: yesGlobal Change Biology, Volume 30, Issue 1, January 2024.
Mediterranean spring ecosystems are unique habitats supporting a remarkable array of biodiversity and providing important ecological functions and ecosystem services. However, global change poses important threats to these freshwater ecosystems, such as changes in climate patterns and increasing human pressures like overexploitation and pollution.

Constant diversification rates of endemic gastropods in ancient Lake Ohrid: ecosystem resilience likely buffers environmental fluctuations [PDF]

open access: yes, 2015
Ancient lakes represent key ecosystems for endemic freshwater species. This high endemic biodiversity has been shown to be mainly the result of intra-lacustrine diversification.
