External and internal shell formation in the ramshorn snail Marisa cornuarietis are extremes in a continuum of gradual variation in development
Conclusion: We could show that the formation of internal, external, and intermediate shells is realized within the continuum of a developmental gradient defined by the degree of differential growth of the embryonic mantle edge and shell gland. The artificially induced internal and intermediate shells are first external and then partly internalized, similar to internal shells found in other molluscan groups.

The C. elegans gene pan-1 encodes novel transmembrane and cytoplasmic leucine-rich repeat proteins and promotes molting and the larva to adult transition
Conclusions: We show that PAN-1 is a critical regulator of larval development. Our data suggests that PAN-1 promotes developmental progression of multiple tissues during the transition from a larva to a reproductive adult. We further demonstrate that the activity of PAN-1 is complex with diverse roles in the regulation of animal development. (Source: BMC Developmental Biology - Latest articles)

Functional modelling of planar cell polarity: an approach for identifying molecular function
Conclusions: We have carried out a systematic comparison of in-silico polarity phenotypes with patterns observed in vivo under different genetic manipulations in the wing. This has allowed us to classify the specific functional roles of proteins involved in generating cell polarity, providing new hypotheses about their specific functions, in particular for Pk and Dsh. The predictions from the model allow direct assignment of functional roles of genes from genetic mosaic analysis of Drosophila wings. (Source: BMC Developmental Biology - Latest articles)

Sexual size dimorphism in ground squirrels (Rodentia: Sciuridae: Marmotini) does not correlate with body size and sociality
Conclusions: We suggest that lack of conformity with Rensch s rule in ground squirrels may be attributed to their low variation in SSD, and briefly discuss three potential causes of small magnitude of SSD in the structural size in rodents: low selection on SSD in structural dimensions, ontogenetic and genetic constraints and the existence of ecological/selection factors preventing the evolution of extensive SSD.

Stopover optimization in a long-distance migrant: the role of fuel load and nocturnal take-off time in Alaskan northern wheatears (Oenanthe oenanthe)
Conclusion: Although birds did not behave like time-minimizers in respect of the optimal migration strategies their surplus of fuel load clearly contradicted an energy saving strategy in terms of the minimization of overall energy cost of transport. The observed low variation in nocturnal take-off time in relation to local night length compared to similar studies in the temperate zone revealed that migrants have an innate ability to respond to changes in the external cue of night length. Likely, birds maximized their potential nightly flight range by taking off early in the night which in turn maximizes their overall migra...

Color plumage polymorphism and predator mimicry in brood parasites
Conclusions: Overall, our data combined with previous results from other localities suggest polymorphism dynamics are not strongly affected by local predator model frequencies. Instead, hosts responses and discrimination abilities are proportional, other things being equal, to the frequency with which hosts encounter various cuckoo morphs near their nests. This suggests that female cuckoo polymorphism is a counter-adaptation to thwart a specific host adaptation, namely an ability to not be fooled by predator mimicry. We hypothesize the dangerousness of a particular model predator (sparrowhawks are more dangerous to adult b...

A pair of Barred Antshrikes (Thamnophilus doliatus) perched near their nest in French Guiana. Pairs of antshrikes perform vocal duets to defend their territories against rivals. Results of a playback experiment reveal that territorial antshrikes respond more aggressively to duets presented through stereo loudspeakers compared to a single loudspeaker, and that both the male and female display equivalent responses to same–sex and opposite–sex rivals.Photo reproduced by permission of Michel Giraud–Audine.

On the Meaning of Alarm Calls: A Review of Functional Reference in Avian Alarm Calling
Abstract A long‐standing question in animal communication is whether signals reveal intrinsic properties of the signaller or extrinsic properties of its environment. Alarm calls, one of the most conspicuous components of antipredator behaviour, intuitively would appear to reflect internal states of the signaller. Pioneering research in primates and fowl, however, demonstrated that signallers may produce unique alarm calls during encounters with different types of predators, suggesting that signallers through selective production of alarm calls provide to conspecific receivers information about predators in the environmen...

Investigating the Effect of Familiarity on Kin Recognition of Three‐Spined Stickleback (Gasterosteus aculeatus)
Abstract The ability to discriminate between related and unrelated individuals has been demonstrated in many species. The mechanisms behind this ability might be manifold and depend on the ecological context in which the species lives. In brood‐caring species, both familiarity and phenotype matching are known to be used in kin recognition. However, results of studies disentangling these two phenomena have proved contradictory. We aimed to broaden our knowledge about the mechanisms of kin recognition using shoaling preferences of three‐spined stickleback (Gasterosteus aculeatus) as a model behavior. In our first experim...

Anatomy of the fully formed chondrocranium of Podocnemis unifilis (Pleurodira: Podocnemididae)
This study describes the anatomy of the chondrocranium of Podocnemis unifilis (Pleurodira, Podocnemididae), based on recently hatched specimens, and cleared and double‐stained specimens. The orbitotemporal region is dramatically different from those observed for other species of turtles in that the: (1) planum supraseptale is greatly reduced and present only as tiny projections on the posterodorsal margin of the interorbital septum, (2) pila metoptica is free from all neighbouring structures and bifurcates distally, (3) pila antotica is greatly reduced, (4) foramina for optic nerve, ophthalmic artery and oculomotor nerve...

The haemocytes of the salp Thalia democratica (Tunicata, Thaliacea): an ultrastructural and histochemical study in the oozoid
In this study, we identified various haemocyte types and their distribution in the common salp Thalia democratica by comparative observations under light and electron microscopy and by histochemical, histoenzymatic and immunohistochemical techniques. By comparing specialisations with those of ascidian haemocytes, we detected an undifferentiated cell type (lymphocyte‐like cell) and three categories with four cell types, that is, (i) phagocytic line (hyaline amoebocyte and amoebocyte with large vacuoles), (ii) mast cell‐like line (granular cell) and (iii) storage cells (nephrocyte). Both phagocytes and granular cells app...
