TL;DR: The regular or obligate aphytophagy of certain lycaenid butterflies (Lepidoptera) is discussed within the framework of the most recent general classification of the family, with emphasis falling on the ecology of myrmecophilous early stages and the significance of their ant-related adaptations.

TL;DR: The temporal distribution of fossil galeomorphs corroborates the hypothesis of relationship suggested by neontological data; there is considerable stratigraphic harmony with Recent phylogenetic data.

TL;DR: A large suite of characters including features of the external shape, mantle glands, gills, foregut, jaw-plates, radula and reproductive system are used to define the genera.

TL;DR: La discussion porte sur la specificite oribate-lichen et l'importance de ces associations pour la fertilite and l'energetique du sol.

TL;DR: The level of endemism in the fiddler crabs is relatively high in comparison with that of other marine groups within the Gulf of Mexico, and the distributional patterns of the endemics could prove useful in reconstructing palaeoecological events of evolutionary significance within the gulf.

TL;DR: The genera discussed are reviewed world-wide and among the non-Australian species: Exosphaeroma papillae Bayliff is transferred to the genus Sphaeromatinae; Dynoides amblysinus Pillai, Dynoide castroi Loyola e Silva and Exoshaeroma globicaudum (Dana) are transferred toThe genus Clianella Boone.

TL;DR: It follows that the Peramura could not lead to the Tribosphenida, which apparently arose from unknown ‘pantotheres’ with not less than nine postcanine teeth.

TL;DR: Etude du crâne et du muscle adducteur de la mandibule dans les familles Gekkonidae, Pygopodidae et Xantusiidae (24 especes)

TL;DR: A new hypothesis of lepidosaurian relationships based on phylogenetic analysis is presented, and a new definition of the Lepidosauria is offered based on derived character states, which suggests squamates, sphenodontids and Gephyrosaurus are lepidosaurs; kuehneosaurs and younginiforms are not.

TL;DR: Large numbers of the tube-building polychaete Diopatra leuckarti Kinberg form extensive mounds of sand on a Hawaiian reef-fiat, providing a stable environment with plentiful resources to support a diverse invertebrate community.

TL;DR: The boundary between reptiles and birds is best placed at a pronounced 'morphological gap', which ensures that most animals conventionally regarded as 'birds' will be retained in the class Aves-though Archaeopteryx would be transferred to the dinosaur suborder Theropoda.

TL;DR: The close similarity of the maternal mouth brooders to each other, and the closer relationship of S. galilaeus to the Oreochromis species than to the Tilapia does not favour the hypothesis of Peters & Berns (1982).

TL;DR: All studied hepialids which have male brush organs exhibit similar flight and mating behaviour: males hover, sit or loop back and forth on the spot in leks; females fly into male aggregations and mate there (although some published observations suggest otherwise).

TL;DR: No single meristic character was found that would adequately separate the seven described species of Liocarcinus and characters that may facilitate separation of later zoeal stages only are listed.

TL;DR: Hyracotherium cuniculus Owen, 1842, from Palaeocene–Eocene boundary strata in NW Europe, was formerly considered to be an equoid, is placed in Cymbalophusgen, in the perissodactyl suborder Ceralomorpha, as one of its most primitive and earliest members.

TL;DR: The structure, site of formation and functions of protochordate blood cells/coelomocytes are considered and the phylogeny and ontogeny of the different cell types in these groups are considered.

TL;DR: Based on protochordates and extant fish, the earliest Palaeozoic vertebrates were microphagous suspension-feeding animals that pumped food-carrying water very slowly and thus required highly concentrated suspensions.

TL;DR: Field and laboratory experiments show that endogenous circatidal rhythms in coastal animals are entrained by exposure to real or simulated tidal cycles of hydrostatic pressure, temperature, salinity, wave agitation, immersion and light, suggesting that tidally rhythmic behaviour is controlled by trulycircatidal oscillators.

TL;DR: It is concluded that the most parsimonious interpretation of the osteology is that the Eichstatt specimen is distinct from the other specimens definitely at the species level and most probably at the generic level.

TL;DR: New prosauropod material from a cave filling of Upper Triassic/Lower Jurassic age in Pant-y-ffynnon Quarry, South Wales, is described and ascribed to Thecodonlosaurus sp.

TL;DR: Possible advantages of didemnid dynamism discussed include maximization of periphery to area (perhaps increasing the efficiency of feeding and/or growth), the exclusion of competitors, and the mingling of clones to facilitate cross-fertilization.

TL;DR: Etude de la morphologie de la poche incubatrice et des pieces buccales des femelles ovigeres de 77 genres de Sphaeromatidae.

TL;DR: Thirty-two species of calcareous tube-dwelling polychaetes (Families Serpulidae and Spirorbidae) are recorded from coral reefs in the Sudanese Red Sea, and post settlement mortality is greater among the SpirOrbidae than the SerPulidae.

TL;DR: This review of the family Loxoconchidae deals principally with six genera that have living representatives in European waters, including the Mediterranean and the Black Sea, and revised diagnoses are given for these genera and their type-species are fully illustrated together for the first time.

TL;DR: The prevalence and seasonal variation in numbers of the two most common parasites are discussed in relation to parasite loads in different ages and sexes of the host fish.

TL;DR: Prcvious uncertainty concerning the numhcr of larval stages in a strepsipteran (Elenchus tenuicornuj) was resolved by transmission and scanning electron microscope observations.

TL;DR: It is proposed to reject the Rhodopidae from the Pulmonata and to include the onchidiids and the Rathouisioidea in the order Archeopulmonata, together with the ellobiids, the otinid slug and the Amphiboloidea.

TL;DR: The ontogeny of the eyes of the common prawn Palaemon serratus is examined using a variety of methods: photography of live specimens, histological sections, SEM and TEM, and the possible phylogenetical significance of superposition, reflecting optics is discussed.

TL;DR: Observation on Cureti3 regulu Evans from Brunei are presented which show that this species may be tended by ants both as larvae and adults, and it is suggested that the Curetinae will be found to be associated with ants when more species have been reared.

TL;DR: Results show that in Lepisosteus ganoine is formed on the inner surface of a cell layer, apparently mesenchymal in origin, proliferating deep to the epidermal basement membrane, and its formation has changed significantly from the pattern in the closely related fossil Semionotidae.
