Extracellular nerve impulse traffic from both mechanoreceptors and putative chemore‐ceptors has been recorded. The first antennae of some, but not all, calanoid groups possess “giant” mechano receptive axons generating very large (mV) extracellular signals. There are two such giant antennal mechano receptors (GAMs) innervating setae of each distal tip. These are sensitive to small (< 10 nm) controlled hydro‐dynamic disturbances, including abrupt displacements and sinusoidal vibrations with frequencies up to and exceeding 2 kHz. Behavioral studies show that escape “jumps\"can be triggered in Labidocera madurae by the same types of disturbances. Sensitivities as low as 4 nm were observed at frequencies of ca. 900 Hz. Behavioral sensitivities are similar to those measured physiologically and suggest that firing of the GAMs is capable of triggering escape behavior, perhaps even with ...","PeriodicalId":360564,"journal":{"name":"Zooplankton: sensory ecology and physiology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124848865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, many suspension-feeding taxa modify food collection when they encounter sestonic particles of differing size, chemical signature, or available density These observations point to a substantial array of mechano- and chemosensory modalities, most of which are based on ciliary structures of the corona and buccal tube. The various cilia, ciliary bundles and cirri are coordinated through a series of nerves and muscles which permit remarkably complicated behaviors when the animals contact individual food cells. Rotifers appear more likely to utilize combined sensory and behavioral functions to accomplish food selectivity than other freshwater zooplankton. However, food cell electivities of the species Brachionus calyciflorus are modified by overall suspended cell density, emphasizing the caution needed when interpreting results of diet selection experiments.","PeriodicalId":360564,"journal":{"name":"Zooplankton: sensory ecology and physiology","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115162518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control response to linearly polarized white light involved an orientation at 90° to the e‐vector. With the addition of NaBr the response became more random. An EC50 (concentration which eliminates the response in 50% of the test individuals) of 1.31 x 10‐1 M NaBr was calculated using the statistic von Mises K.

Suspended particles not only affect visibility and net primary productivity, as light penetration is reduced, but may also affect the ability of herbivorous zooplankton to locate and ingest food. In Swan Lake, an oligotrophic lake in northwestern Montana, the dose association between zooplankton population development and seasonal maxima in turbidity levels suggests that the community present during peak turbidity is minimally impacted by suspended sediments. This report presents the results of laboratory investigations into the effect of suspended sediments on feeding by the copepod Diaptomus ashlandii, the dominant zoo‐plankter in Swan Lake. Ingestion rate for copepods feeding on 32P labeled algae was significantly reduced in the presence of suspended particles at all turbidity levels tested (5 to 200 NTU's) compared to ingestion rate in the absence of suspended particles (0 NTU's).","PeriodicalId":360564,"journal":{"name":"Zooplankton: sensory ecology and physiology","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126005388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aims of this contribution are to defend that statement, with selected examples, and to suggest that neural analysis, particularly sensory physiology, has great explanatory power of ecologically significant behavior. I have to begin with a personal note about plankton, recalling the lasting impression made long ago by a film on invertebrates in the Arctic where scyphomedusan jellyfish were pulsing at a rate well within the range familiar in summer temperate waters, warmer by 20o C. I must have been influenced by this observation and my own experiences in a study of the neural basis of fluctuations in the rate of pulsation of medusae (Bullock 1943), some of which was made in December 1941 in Pensacola, where my wife and I collected Rhopilema cruising at random in the Sound, stopped now and then by Army bridge guards concerned about saboteurs in that first fortnight after Pearl Harbor. At any rate, by the early fifties about half of my laboratory group was devoted to the physiological ecology of temperature acclimation in marine invertebrates. That field, which I left in the early sixties, still offers a challenge in the ecologically fundamental question of why some species are able to acclimate much more than others. The proposal I made in 1955, that different rates in the same organism acclimate to different degrees, resulting in greater disharmony in some species than others, may still be viable and most likely applies to rate processes in sensory and central nervous functions, among others. Medusae are large animals, relatively, although generally treated as planktonic. The first reaction from most workers when neurophysiology of plankton is mentioned concerns their small size or gelatinous nature. The first message I bring is not new but also not widely appreciated.","PeriodicalId":360564,"journal":{"name":"Zooplankton: sensory ecology and physiology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123813271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
