Planorbidae, Lymnaeidae and Physidae of Ecuador (Mollusca: Basommatophora) [PDF]

open access: yesMemórias do Instituto Oswaldo Cruz, 2004
In the course of a trip to Ecuador I had the opportunity of collecting topotypic specimens of the following nominal species of pulmonate molluscs: Biomphalaria cousini Paraense, 1966; Planorbis equatorius Cousin, 1887; P. canonicus Cousin, 1887; Lymnaea cousini Jousseaume, 1887 and P. boetzkesi Miller, 1879. Additional findings were: Helisoma trivolvis

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Observação do comportamento biológico de Biomphalaria glabrata de concha anômala Observations on the biological behaviour of Biomphalaria glabrata with an anomalous shell

open access: yesRevista de Saúde Pública, 1975
Foi encontrado na criação de Biomphalaria glabrata em laboratório, um caramujo vivo com anomalia na concha. A anomalia consiste na mudança de nível das voltas. O exemplar foi isolado para estudo de seu comportamento biológico.

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3355-3369, November 2025.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.

Effects of competition and predation risk from a life history intraguild predator on individual specialisation

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1811-1822, September 2025.
Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

The Nature of Oceanic Dispersal in the Diversification Process on Insular Systems in Asia

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim To clarify the characteristics and contribution of oceanic dispersal (OD), a representative of long‐distance dispersal, to phylogenetic diversification on insular systems. Location Eastern Eurasia. Time Period Post‐Neogene. Major Taxa Studied Freshwater snails of the genus Gyraulus (Mollusca: Gastropoda). Methods We conducted comprehensive

Investigating the Effects of Flow Regulation Combining Stream Geomorphology With Macroinvertebrate Ecology: A Case Study in the Orobic Alps (Italy)

open access: yesEcohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT Mountain streams exhibit hydrogeomorphological heterogeneity, which is further intensified by the presence of hydraulic infrastructure. Despite extensive research on the influence of hydrological conditions and flow regulation on ecology, there is a notable absence of holistic studies investigating stream dynamics from both geomorphologic and ...
