“…Some classic examples are colour patterns in fish (Winge, 1927), in poppies (Philp, 1934), in grouse locusts (Nabours, 1929;Nabours et al, 1933), in helicid snails (Cain et al, 1960(Cain et al, , 1968 and in butterflies (Sheppard, 1959;Clarke and Sheppard, 1972). Complex loci are also responsible for the inheritance of the elements of the heterostyle condition in primroses (Mather, 1950;Dowrick, 1956) and of the Rhesus blood groups in man (Fisher, 1953).…”

“…0.07 g), diurnal insects that inhabit biomes ranging from tropical rainforests to arctic regions of Europe, Asia and North to South America (Mexico) [17,18]. Pygmy grasshoppers provide one of the classic examples of colour polymorphism, and intraspecific variation has been documented and analysed for almost a century [19,20]. Colour and pattern in T. subulata are genetically influenced and not affected by developmental plasticity (see Forsman et al [19] and references therein).…”

“…Tetrix subulata has a high reproductive capacity; each female may produce several egg pods per season, consisting up to 35 eggs per pod. They have a polygynandrous mating system and females mated to several males may produce half-sibling offspring that are more colour morph diverse [9,20]. Like many other insects, T. subulata are wing dimorphic [18,20], and macropterous individuals with functional wings are capable of active flights of up to 100 m. However, mark-recapture data of freeranging individuals indicate that T. subulata are sedentary and normally move only a few metres per day [23].…”

Variation in founder groups promotes establishment success in the wild

Environmental changes currently pose severe threats to biodiversity, and reintroductions and translocations are increasingly used to protect declining populations and species from extinction. Theory predicts that establishment success should be higher for more variable groups of dissimilar individuals. To test this 'diversity promotes establishment' hypothesis, we introduced colour polymorphic pygmy grasshoppers (Tetrix subulata) to different sites in the wild. The number of descendants found at the release sites the subsequent year increased with increasing number of colour morphs in the founder group, and variation in founder groups also positively affected colour morph diversity in the established populations. Since colour morphs differ in morphology, physiology, behaviour, reproductive life history and types of niche used, these findings demonstrate that variation among individuals in functionally important traits promotes establishment success under natural conditions, and further indicate that founder diversity may contribute to evolutionary rescue and increased population persistence.

“…A green-brown polymorphism that seems to reflect plasticity in response to humidity or temperature experienced during development is common among certain acridoid grasshoppers (Rowell 1971). At the other end of the spectrum, the family Tetrigidae contains a number of highly color-polymorphic species where the polymorphism appears to be under strong genetic control and color and pattern are little influenced by plasticity in response to environmental conditions (Nabours 1929;Fisher 1930Fisher , 1939. Alternative color variants of Tetrix species are eco-morphs that differ not only in coloration but also in morphology, physiology, behavior, and life-history traits (Forsman 1999(Forsman , 2000Forsman and Appelqvist 1999;Forsman et al 2002;Forsman 2003, 2006).…”

Abstract:Color polymorphisms in animals may result from genetic polymorphisms, developmental plasticity, or a combination where some phenotypic components are under strong genetic control and other aspects are influenced by developmental plasticity. Understanding how color polymorphisms evolve demands knowledge of how genetic and epigenetic environmental cues influence the development and phenotypic expression of organisms. Pygmy grasshoppers (Orthoptera, Tetrigidae) vary in color pattern within and among populations. Color morphs differ in morphology, behavior, and life history, suggesting that they represent alternative ecological strategies. Pygmy grasshoppers also show fire melanism, a rapid increase in the frequency of black and dark-colored phenotypes in populations inhabiting fire-ravaged areas. We examined the influence of plasticity on color polymorphism in the pygmy grasshopper Tetrix subulata (L., 1761) using a split-brood design. Individuals were experimentally raised in solitude on either crushed charcoal or white aquarium gravel. Our analyses uncovered no plasticity of either color pattern or overall darkness of coloration in response to rearing substrate. Instead, we find a strong resemblance between maternal and offspring color patterns. We conclude that pygmy grasshopper color morphs are strongly influenced by genetic cues or maternal effects, and that there is no evidence for developmental plasticity of coloration in response to rearing conditions in these insects.Résumé : Le polymorphisme de la coloration chez les animaux peut résulter de polymorphismes génétiques, de plasticité au cours du développement ou d'une combinaison dans laquelle certaines composantes phénotypiques sont sous un fort contrôle génétique, alors que d'autres aspects sont influencés par la plasticité du développement. Une compréhension du développement des polymorphismes de la coloration exige une connaissance de l'influence des signaux environnementaux génétiques et épigénétiques sur le développement et l'expression phénotypique des organismes. Les tétrix (Orthoptera, Tetrigidae) ont des patrons de coloration qui varient au sein des populations et entre les populations. Les différents morphes de couleur diffèrent par leur morphologie, leur comportement et leur cycle biologique, indiquant qu'il s'agit de stratégies écologiques de rechange. Les tétrix possèdent aussi un mélanisme relié au feu, soit une augmentation rapide de la fré-quence des phénotypes noirs et de couleur foncée dans les populations qui vivent dans des zones ravagées par le feu. Nous examinons l'influence de la plasticité sur le polymorphisme de la coloration chez des criquets granulés, Tetrix subulata (L., 1761), qui utilisent une stratégie de couvain divisé. Nous avons élevé expérimentalement des individus solitaires sur du charbon de bois écrasé ou sur du gravier blanc d'aquarium. Nos analyses ne décèlent aucune plasticité dans le patron de coloration, ni dans la noirceur globale de la coloration en réaction au substrat d'élevage. Nous observons plutôt ...
