gibberula is a genus of minute sea snail , a marine gastropod mollusk or micromollusk in the family cystiscidae , previously placed in the family marginellidae , the margin shells or marginellids .

( note : gastropod taxonomy has been in flux for many years . this is especially true currently , because of new research in molecular phylogeny . because of all this ongoing change , different reliable sources can yield very different classifications , especially within certain poorly understood groups . ) the type species of the genus gibberula swainson , 1840 is g. zonata swainson .

other genus-group names are available for small shells resembling gibberula .

these include granula jousseaume , 1875 and kogomea habe , 1951 .

they are distinguished from gibberula only on the basis of smaller size and other rather tenuous conchological differentiations .

taxonomy the separation between the genera persicula and gibberula is not clearcut and currently follows a rather arbitrary criterion where the large species with ( usually with complex colour pattern ) are placed in persicula and the smaller species with a banded or uniform colour pattern in gibberula , leaving in between many ambiguous species . to date ( 2010 ) there is no phylogenetic analysis behind the current generic placements .

students in ecology and systematics of diatoms contribute to the diatoms of the united states . for a final project , students intensively research a single taxon and submit their work to the review board . several taxa from 2015 are completed .
mark edlund and sylvia lee taught the class . students came from university of iowa , university of southern california long beach , university of nevada reno , and mcgill university . nick schulte was awarded the kingston teaching fellowship , and was joined by ian bishop and david burge , bringing together the kingston trio . adam heathcote provided a paleolimnology lesson and lead the class on a coring expedition to east lake okoboji and lake minnewashta . visiting researchers also included lynn brant , evelyn gaiser , and steve main .
students investigated the morphology , allometry , and sexual reproduction of encyonema reimeri from west lake okoboji , iowa . collections made on 18 may 2015 showed a bimodal distribution of cell sizes that extended the upper size range known for this taxon , a positive relationship between valve length and breadth , and no apparent relationship between striae density and cell size . the class returned to collect new material after two weeks and found that the size distribution of cells has shifted downward and that there was evidence that the population was undergoing sexual reproduction . two gametangial cells were paired in a copulation mucilage and each produced two isogametes . pairing and fertilization most like followed geitler ' s normal type 1c reproduction with no apparent relationship between gametangial cells and expanding auxospores .
a second project focused on the seasonal succession of diatom epiphytes on cladophora at triboji beach , west lake okoboji from 13 may , 26 may , and 8 june 2015 . students practiced diatom enumeration methods and were introduced to ordination . they observed a shift in the epiphyte community , with diatoms from the earliest and latest collection dates exhibiting the most dissimilar assemblage composition .

. . . different reproductive aspects , such as gonadal cycle , time of spawning , and spawning behavior , have been extensively studied in a number of limpet species . these gastropods often exhibit external fertilization ( e . g . , southward and dodd 1956 ; picken 1980 ; picken and allan 1983 ; niu and fuji 1989 ; brêthes et al . 1994 ; stanwell - smith and clarke 1998 ; morriconi 1999 ; hodgson and eckelbarger 2000 ; rocha - barreira 2002 ; mccarthy et al . 2008 ; prusina et al . 2014 ) . information on the gonadal histology and gametogenesis of some limpet species is also available ( bernard 1988 , 1989 ; hodgson et al . 1996hodgson et al . , 2007hodgson et al . , 2012hodgson and eckelbarger 2000 ; hodgson 2009 ) . . . .
. . . our observations indicate that the male gonad is organized similarly to that of n . deaurata ( morriconi 1999 ) . the morphology of the spermatogenic cells in n . concinna resembles those of other gastropods ( hodgson and bernard 1988 ; rocha - barreira 2002 ; hodgson et al . 2012 ; prusina et al . 2014 ; chen et al . 2015 ) . there is little information on the morphological types of spermatozoa in members of the family nacellidae , with the nucleus being triangular in cellana radiata capensis and elongated in n . delesserti bernard 1988 , 1989 ) , resembling that of n . concinna . . . .
. . . among the factors that favor the use of limpets in biomonitoring programs are the existence of a vast knowledge about their biology ( e . g . orton et al . , 1956 ; cúrdia et al . , 2005 ; coleman et al . , 2006 ; mccarthy et al . , 2008 ; ribeiro et al . , 2009 ; prusina et al . , 2014 ; fernández et al . , 2015 ; fernández et al . , 2016 ) , their wide distribution ( poppe and goto , 1991 ) , their abundance , and their sedentary lifestyle ( fretter and graham , 1994 ) . in addition , these organisms play a key role in the ecosystem by regulating the degree of algal coverage and , consequently , succession processes in rocky intertidal communities ( coleman et al . , 2006 ) . . . .
a review of the empirical literature on the use of limpets patella spp . ( mollusca : gastropoda ) as bioindicators of environmental quality
. . . the reproductive cycle of p . rustica was described earlier in the basque country [ 23 ] and the portuguese coast of the northeast atlantic [ 24 ] . furthermore , very few studies have been devoted to the reproduction of p . rustica of the mediterranean , with the exception of a first contribution in the algerian coast [ 12 ] and a second in the adriatic sea [ 25 ] . in algeria , the lack of work on the reproduction of p . rustica based on histological analysis , justifies our investigations on oogenesis of the latter . . . .
. . . according to [ 32 ] in their study of spisulasolida , gametogenesis began when the seawater temperature started to decrease , and spawning occurred with low temperature values that increased progressively . indeed , the temperature has often been associated with reproductive cycles of patella species [ 4 , 20 , 25 ] . salinity is an important ecological factor , which itself can be affected by seasonal variation in temperature . in this study , the lowest salinity was recorded during the cold time of year . . . .
. . . the dominance of males is also known in both species p . vulgata and p . ulyssiponensis living on the irish coast [ 29 ] , and p . depressa collected in the portuguese coast by [ 43 ] . unlike our results , [ 25 ] reported that females dominate compared to males in p . rustica of adriatic sea . the gonad index fluctuated widely during the study period with a peak recorded in november . . . .
. . . based on these data , growth line formation was set for may . since the reproductive peak of p . rustica was in november ( see prusina et al . , 2014b ) , the birth date was set as december 1st . consequently , a first growth line represents six months instead of twelve and this calculation was taken into account when estimating the age and growth of p . rustica . . . .
. . . some of the possible reasons for annual growth line formation are food supply , thermal tolerance and ductive processes such as gonad development and spawning . according to the reproductive study from the same location ( prusina et al . , 2014b ) , p . rustica has a prolonged period of gamete development starting from february and extending to september when majority of limpets ( 70 % of females and 100 % of males ) contained gonads in late developmental stages . the spawning peak was in november and december for both sexes , followed by planktotrophic larval stage in december ( prusina et al . , 2014b ) . . . .
