 issued from : C.W. Gill in Mar. Biol., 1986, 93. [p.451, Fig.1, (3-5)]. Scanning transmission electon photomicroscopy. from female (Roscoff, France): 3, setae on preaxial edge of A1, showing various positions of pegs (pg); 4, typical arrangment of Type 1 (t1) and Type 2 (t2) setae, peg (pg), and pores (p); 5, detail of peg and pore. Nota : The A1 musculature is organised into five discrete bundles around the periphery of the A1 close to the cuticle. Muscle bundles run in the sub-, post-, and supra-axial regions of the A1, so their contraction causes the A1 to be flicked backwards. A pre-axial set is innervated by a pair of neurons which are associated with mitochondria. Nervous processes are present in the post-axial part of the A1. Setae, pegs and pores are present on the A1. The external morphology differs with regard to size, and their ultrastructure shows that they may be of two distinct types ; Type 1 seta supra-axial (t1) and Type 2 seta sub-axial (t2) . One of each type probably occurs in the pair of setae at each segment junction. The histology and behavioural experiments concerning A1 (see Gill , 1985 ; Gill & Crisp, 1985), demonstrate that the Type 1 setae have the fine structure of a mechanoreceptor, and are used to detect distant water disturbances. The type 2 setae may be chemosensory (as aesthetes have been identified on the A1 of other species of copepods [see laverack, 1968 ; Griffiths and Frost, 1976 ; Gill, 1983 ; Fleminger, 1985]. The antennulary pegs do not appear to be innervated. Amputating the A1 of individuals prevented it from detecting distant water disturbances, but not those nearby (Gill & Crisp, 1985), so mechanoreceptors must be present on other areas of the body.

 issued from : C.W. Gill in Mar. Biol., 1986, 93. [p.452, Fig.2, (6-7)]. SEM photography Female: 6, position of several sensillae on anterior of cephalosome; a = antennule; f = frontal horn (rostrum); sf = supra-frontal sensillae; pl = large pore; cs = coeloconica sensilla; 7, detail of coeloconica (cs) and pore (p). Nota : On dorsal forehead two ‘supra-frontal sensillae’ (frontal organ) (see Elofsson, 1971) occur near a large central pore, on either side of the sensillae is a coeloconica sensilla and a small pore which may be chemoreceptors receiving external stimuli (see Fleminger, 1973). There are other small pegs and large pores of < 0.0045 mm diameter in this area ; The frontal horns (rostrum) are probably sensory and their cuticle is perforated by many pores in Calanus finmarchicus (Elofsson, 1971), but not in adult Temora longicornis. Of the other integumental structures present on the cephalosome, large pores are most common.

 issued from : C.W. Gill in Mar. Biol., 1986, 93. [p.452, Fig.1, (8)]. SEM photography Female: 8, patches of epicuticular spines (se), a seta (s), peg (pg), large pore (pl), and pore (p) on dorsal surface of metasome. Nota : Structures resembling sensillae are most common on the dorsal surface of the metasome, which is often partly covered by epicuticular spines, occuring in patches and pointing in a posterior direction ; Setae, pegs and large pores are distributed on the integument in patterns that form signatures characteristic of species (see Fleminger, 1973).

 issued from : C.W. Gill in Mar. Biol., 1986, 93. [p.452, Fig.1, (10)]. Light microscope Female: 10, last segment of urosome (u) and caudal rami. s = setae. Nota : The caudal rami have apical setae, with a single row of narrow setae on the inner edge of each caudal ramus. Nota : The fine setae on the caudal rami and metasome may be mechanosensory. The specimens are very sensitive to water jets directed at the urosome and caudal rami. It is possible that the fine setae on the caudal rami respond to small rapid movements of water in a similar way to the setae on the anal cerci of cockroaches and crikets. These insect setae warn against sudden attack from behind by detecting rapid air currents, causing the insect to escape (Cambi, 1890).

 Issued from : N.J. Bannister in J. mar. biol. Ass. U.K., 73. [p.100, Fig.3]. SEM of Temora longicornis from Menai Bridge pier (Wales). A: a pore on the second swimming leg, with vesicular material at its opening; B: pore (p) on the third swimming leg adjacent to a spine (sp) with granular material (g) around the pore opening and along the spine. Scale bars: 4 µm (A); 10 µm (B). Nota: The large secretion granules in the secretory cells stained suggest the presence of protein. The observations lend support to the view that non-luminous secretion may act as an antifouling agent. It was noticed that the cuticle of these animals was remarkably free of any fouling organism, especially bacteria.

Long-term change of Temora longicornis abundance in a Dutch tidal inlet (Marsdiep, Texel, North Sea) in relation to eutrophisation.
Nota: The long-term increase of Temaora longicornis could have been induced by an increased reproduction and growth rate or by a decreased mortality.
It is not likely that mortality by predation decreased, because the the carnivore predators tended to increase (see Boddeke & Hagel, 1991). The results suggest that eutrophisation had a stimulating effect on the abundance, and possibly the length of the growing season in relation with a corresponding lengthening and earlier start of the Phaeocystis bloom. |

Some characteristics of 3 successive generations of Temora longicornis per year.
Nota: The results in Table suggest that the first 2 new generations of the year can cope with mortality rates of 0.10 to 0.11/day, but the third generation in summer only with 0.06/day.
It seems that the deterioration of food condition in the sea causes a decline in numbers already in the second new generation, spawned in May-June. The low, but steady egg production from June to September may be very important to maintain a pelagic hibernating population, which can produce the first new generation in spring.
It has been proposed, that for the development of the first generation neritic pelagic copepod populations depend on resting eggs hatching in the bottom sediment. Lindley (1986) mentioned T. longicornis nauplii emerging from bottom sedment of the southern North Sea. Since a tenfold multiplication in the first new generation is possible already at a realistic mortality rate of 0.07/day, hatching of resting eggs does not seem to be essential for persistence. |

Table 2: Daily egg production per female required for stable populations of T. longicornis at high food level.
Table 3: Daily egg production per female required for stable populations of at low food level.
Nota: Daily fecundity required for a stable population at different temperatures and mortality suggest taht at 5°C the population can only persist at high food level and a mean mortality below about 0.07/day. Maximum daily fecundity of 30 eggs p.female at high food level and temperature above 10°C enables the population to withstand a mortality rate up to 0.5/day. A low but non-zero fecundity at low food level and high temperature can stabilize the population at a mortality rate of about 0.05/day.

The effect of size and temperature on the frequency of limb beat of Temora longicornis (collected from Menai Strait, Gwynedd, Wales):
Fig.1: The natural log (ln) plot of the limb (A2) beat frequency (Hz) for females recorded at 10°C, against cephalothorax length.
Fig.2: Mean values of limb (A2) beat frequency between 5 and 25°C for the winter population acclimated at 5 and 15°C (range marks indicate SE); mean of 5°C acclimated copepods = 24.74; mean of 15°C acclimated copepods = 22.68; least significant difference (T 5%) = 0.77 (P < 0.005, highly significant).
Nota: The limb (A2) frequency recorded for females with cephalothorax lengths varying from 53.10 to 91. 90 micrometers. The rate of limb beat ranged from 15.0 to 25.3 Hz, and decreased logarithmically with a logarithmic increase in the size of the copepods.
The effect of temperature at different season shows that over the range of temperature studied, the frequency of limb beat varied from 10.6 to 37.8 Hz during the winter, and from 7.9 to 38.0 Hz in the summer. The swimming rate increased with increasing temperature up to the point where damaging or inhibitory effects occurred. T. longicornis was adversely affected at temperatures > 20°C in winter, and stopped swimming altogether at temperatures > 25°C. No difference in rate of limb was found between similar sized males and females. |

Feeding efficiency in percent for Temora longicornis feeding on natural particulate matter from Bedford Basin, Nova Scotia. (Canada).
A: 9 December 1975; B: 31 May 1976.
Nota: At low ambient concentration in the fall large particles are used principally (A), but as the particle concentration was increased artificially (maximum 5.409 ppm) feeding efficiency followed a curve similar to that exhibited by animals grazing at higher ambient levels, particularly of smaller sized particles, in spring (B). Hence, feeding efficiency is clearly influenced by concentration and, though not shown by these figures, by where the concentration is distributed over the particle spectrum.
Perhaps the influence of distribution of particle concentration on feeding performance is better illustrated by figure 63, in which the author has plotted filtering rate, as a means of scaling feeding performance in a series of ''manipulated'' particle spectra, against particle concentration using the same experimental data from which figure 61 (A) was derived.. Here is concentrated or diluted certain portions of the spectrum only. The scal for filtering rate appears on right on the left ordinate and concentration on the left. |

Nota: The bottom graph reprents a relatively flat spectrum, noting that the ordinate has a different scale than in the other four graphs. Feeding, what little occurs, is concentrated in the 5 to 10 µm range. The next graph up depicts feeding at ambient concentration which is concentrated in the 30 to 80 µm range, but note that there is some utilization at the small end of the spectrum. The remaining three graphs show the attempt of the author to increase concentration in the same areas of the spectrum where feeding was occurring at ambient concentration |

Schematic diagram of the behaviour of Temora longicornis grazing on Coscinodiscus wailesii.
After capture of the cell, the copepod was able to fix the position of the diatom relative to itself with considerable accuracy. When a piece of the frustule is bitten off, the protoplasma, i.e; the nutritious content of the diatom, concentrates on the opposite side of the cell which also occurs when a frustule is broken with a needle. During feeding, this happened as soon as the frustule is broken by the mandibles of the copepod (Fig. 3c). T. longicornis then turnede the cell with its feeding and locotory appendages till the concentrated protoplasma was directly adjacent to the mouth (Fig. 3d). The copepod bit again a piece out of the frustule and then could reach and ingest the cell content (Fig. 3e). The empty silica frustule was ultimately rejected. Almost no microscopically visible material digestible for the copepod remained within the diatom shell. The rejected emptied frustules showed a characteristic pattern with mostly two (up to five) parts bitten out of the frustules (Fig. 3f). The handling time ranged from 20 to 259 s (with a mean of 107 s). |

Light micoscope micrographs of faecal pellets produced by T. longicornis grazing on a monoculture of Coscinodiscus wailesii from Helgoland Roads (North Sra).
The faecal pellet content consists mainly of brownish unidentifiable matter and only very few pieces of diatom frustules can be identified (arrow in B).
For the author (p.254), analyses of gut or faecal pellet contents can give a qualitative insight in what have been grazed by a copepod, but can rarely provide quantitative results (see Wexels Riser & al., 2003). In cases where copepods do not ingest whole cells, interpretation of stomach or faecal pellet contents may be difficult or even impossible as only a few pieces of evidence of the diatom prey may be found. |

See Table 1: Cell-specific content.
Temora longicornis sampled from the central North Sea and kept in the laboratory for more than 10 generations. Female Individuals isolated, cultured at 14°C in the dark and fed in excess (> 400 µg C /liter)
Nota: Although diatoms were ingested at high rates, they yielded a variable egg production response, ranging from high egg production in four species (Thalassiosira rotula, T. weissflogii, Chaetoceros affinis) to lox egg production in two species (Leptocylindricus danicus, Skeletonema costatum).
Egg hatching rates decreased after 4 days in all diatom treatments, irrespective of the egg production rate and without any relationship to diatom aldehyde production. Similarly, no evidence was found that diatoms are per se nutritionally inferior to nondiatom food.
The authors suggest that hatching^specific nutritional deficiences might be induced by incomplete digestion following from the low gut passage time of diatoms, as indicated by a strong correlation between egg viability and fecal pellet production. |

Habit (after Rose, 1957; modified), range of prosome length in situ (Halsband-Lenk, partly unpublished) and geographical distribution in the Atlantic and adjacent seas of Temora longicornis and Temora stylifera (b).
The target is the temperature impact on reproduction and development of two congener copepod pairs inhabiting different biogeographic regions to their geographic distribution patterns (from two stations in the North Sea, Helgoland Island and the Mediterranean Sea, Villefrance -sur-Mer).
Nota: The differences of thermal tolerance between these congeners confirmed the classification as a cold-temperate (T. longicornis and a warm-temperate species (T. stylifera and hence their geographic distribution.
T longicornis tolerated the whole temperature range found in the North Sea as expected from its perennial occurrence rgere. The fact that it could not withstand temperatures > 22.5°C, expains its absence from warmer environments and its restriction to the northern hemisphere with a southern boundary coinciding with the 20°C isotherm of the Atlantic in summer (Lindau, 2001).
Temora stylifera, in contrast, was the only species that could survive temperaturs > 25°C, at least in the adult stage, and is accordingly distributed in lower latitudes. Limitation to the north corresponded to the 10°C isotherm (Lindau, 2001), representing probably the northern margin of reproductive success, while its occurrence in the English Channel seems more likely a result of advection. However, the thermal optimum of the female thermal tolerance and the reproductive thermal response at 10-15°C (see Table 5) seemed at first sight surprisingly low, since T. stylifera is considered as a warm-temperate species. On the other hand, Abou-Debs & Nival (1983) also found an optimum of the re^productive thermal response at 16°C and declining egg production rates towards the temperature extremes of their Mediterranean habitat (13 and 23°C). In fact, T. stylifera reproduces mainly during autumnal cooling in the western Mediterranean (Halsband-Lenk & al., 2001). Similar to female thermal tolerance and reproductive thermal response, development of some instars was favoured at 15°C. At 10°C, no development was possible in culture. Assuming that population development takes place in autumn following the reproduction peak, the preference of a low autumnal temperature matched the species' life strategy in situ. Although the limits of temperature tolerance would allow survival and development at higher temperatures, T. stylifera tended to prefer intermediate temperatures in the Mediterranean, possibly to avoid resource competition with other copepods (C. Razouls, 1974, up to date mainly with the more abundant species as Centropages typicus, before the climatic change, and the abundance of Clausocalanus spp.), consequently, thermal tolerance was not necessarily correlated with the optimum.
In the aurthors' conclusion, in a given environment, interactions between species lead to extinction of less adapted species and dominance of better adapted ones, resulting in a specific spatial and temporal species composition. A shift in temperature, either latitudinal or a seasonal scale, will modify these interactions and result in a changed combination of species, e.g. as result of climatic changes like global warming. The impact of such long-term changes on the zooplankton communities requires more information on how populations respond to critical temperatures, both from an ecological and physiological approach. [therefore the knowledge of the genome and the variability intraspecific, and probably existence of geographic stairs. CR]. |

Stage durations (day) and mortality rates (day-1) of Temora longicornis at different temperatures in the North Sea.
Nota: Stage durations of nauplii were slightly shorter in T. longicornis than in T. stylifera at 15 and 20°C. Development times of T. longicornis decreased from 15 to 20°C, while NIV, NV and CI of T. stylifera developed more quickly at 15°C than at 20°C. At 10°C, no development was observed beyond NI in T. stylifera. Relative development times of both congeners were equiproportional (see in Table 6).
Mortality rates of T. longicornis were 0.150 and 0.172 day-1 for nauplii at 15 and 20°C, respectively, and 0.103 day-1 for copepodites at 20°C. T. stylifera had very high death rates in nauplii at 20°C (0.339 day-1 prior collapse of the culture and were considered as artefact. At 15°C, nauplii mortality was 0.092 day)-1. Negative mortality was observed in copepodites, due to the sampling technique, i.e. a misrepresentation of specimens in the subsamples, which is attributed to inefficient mixing of the culture before sampling. Compare with T. stylifera (Table 3, Ts) for the same authors. |

Temora longicornis and Temora stylifera comparison: Synthesis of results from incubation in a temperature gradient from 0 to 35°C.
FTT = female thermal tolerance. RTR = reproductive thermal response. ETR = embryonic thermal response.
The two Temora, from the North Sea and the Mediterranean Sea considered, showed quite different female thermal tolerance. T. stylifera females stayed alive and maintained reproduction up to 30°C, whereas T. longicornis could not withstand temperatures above 22°5. Optimal survival of T. stylifera occurred at 10 and 15°C, while 2 and 5°C were lethal. The mortality observed at 20°C can be considered as suspect. T. longicornis showed low mortality between 0 and 22°5 without any clear optimum.
The reproductive thermal response (RTR) also differed between the Temora congeners. Egg production of T. longicornis ranged between 5 and 10 eggs female-1 day-1 from 0 to 15°C, peaked at 20°C with 18.8 eggs female-1 day-1 and decreased sharply at 22°5 (see in fig.6c).
In contrast, T. stylifera produced no eggs below 8°C; optimum occurred at 15°C with 25.7 eggs female-1 day-1, at higher temperatures the egg production rates declined (see in fig. 6e).
The embryonic thermal response (ETR) showed different tolerance limits for T. longicornis (0-22°C) and T. stylfera (10-28°C).
The Belehradek function of T. stylifera had a similar curvilinearity as that of T. longicornis in March, but was displaced towards higher temperatures (see in fig. 9, c, e). Cold temperatures inhibited development of T. stylifera embryos. No nauplii hatched below 10°C and the proportion of viable eggs increased with temperature from 10 to 20°C and slightly decreased at 25°C. In contrast, hatching success of T. longicornis was high at all temperatuirs between 2 and 22.5°C, but no eggs developed beyond this limit.
A seasonal comparison of embryonic thermal response was available for T. longicornis (see in fig.9, c). Eggs developed relatively quickly at low temperatures in summer, but slower in winter; In March 1996, embryos needed more time to hatch at a given temperature than in June 1996 (p <0.10001), and than from June to September 1999 (p <0.0001). The difference was less significant between June 1996 and June to September 1999 (p <0.01).
Hatching success was maximum or very high at any temperature situation in T. longicornis. In T. stylifera, survival of eggs increased linearly with temperature from 52 % at 10°C to 90 % at 20 and 25°C.
In the Temora species, naupliar durations were similar to copepodite durations, except when mortality stopped development.
The thermal tolerance ranges were rather similar in all parameters considered. However, in some cases, a slight decrease of tolerance was observed in subsequent life phases, i.e. in T. stylifera whose temperature range was wider for female survival than for reproduction and even narrower for embryonic development.
Heat death occurred in T. longicornis, except T. stylifera, at 30°C or below, indicating that this temperature represents a threshold beyond which a selective measure is necessary to ascertain survival, e.g. the production of heat shock proteins reported for various marine organisms (Hofmann, 1999). Depression of development rate (i.e. increasing development time) as an expression of physiological inefficiency at the upper end of a species' thermal range (repoerted for embryos of Acartia clausi, Temora stylifera, Centropages chierchiae; Bernard, 1971; Landry, 1975). The authors observede prolonged embryonic duration at 25°C or above, both in the North Sea (Centropages hamatus) and in the Mediterranean (Centropages typicus). |
