Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Biodiversity of macrozoobenthos in a large river, the Austrian Danube, including quantitative studies in a free-flowing stretch below Vienna: a short review [PDF]

open access: yes, 2005
The Danube is ca. 2850 km in length and is the second largest river in Europe. The Austrian part of the Danube falls 156 metres in altitude over its 351 km length and, since the early 1950s, the river has been developed into a power-generating waterway ...

Lacustrine mollusc radiations in the Lake Malawi Basin : experiments in a natural laboratory for evolution [PDF]

open access: yes, 2012
In terminal Pliocene-early Pleistocene times, part of the Malawi Basin was occupied by paleo-lake Chiwondo. Molluscan biostratigraphy situates this freshwater lake either in the East African wet phase between 2.7-2.4 Ma or that of 2.0-1.8 Ma.

Prey preference follows phylogeny: evolutionary dietary patterns within the marine gastropod group Cladobranchia (Gastropoda: Heterobranchia: Nudibranchia)

open access: yesBMC Evolutionary Biology, 2017
The impact of predator-prey interactions on the evolution of many marine invertebrates is poorly understood. Since barriers to genetic exchange are less obvious in the marine realm than in terrestrial or freshwater systems, non-allopatric divergence may ...

The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]

open access: yes, 2000
Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Phylogenomics and the evolution of larval feeding habits in the blow flies (Diptera: Calliphoridae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Phylogenomic data from anchored hybrid enrichment provide a new phylogeny of Calliphoridae that delimits the family and confirms division into eight monophyletic subfamilies. Fossil‐calibrated divergence times place the origin of Calliphoridae in the mid‐Eocene (ca. 41 Mya) along with other rapidly radiating families of oestroid Diptera. Reconstruction
