AbstractExplaining why breeding colonies vary in size has been a persistent problem in the study of animal spatial distribution. One hypothesis is that colony size reflects local food availability, which may be affected by the number of conspecifics feeding in a given area. We investigated whether colony size in Cliff Swallows (Petrochelidon pyrrhonota) was influenced by competition for food from birds in nearby colonies. Because we knew where Cliff Swallows foraged in relation to their colonies, we could designate for each colony site which neighboring colonies shared its foraging range. If i

Abstract:
The evolution of modular colonial animals such as reef corals and bryozoans is enigmatic because of the ability for modules to proliferate asexually as whole colonies reproduce sexually. This reproductive duality creates an evolutionary tension between modules and colonies because selection operates at both levels. To understand how this evolutionary conflict is resolved, we compared the evolutionary potential of module- and colony-level traits in two species of the bryozoan Stylopoma, grown and bred in a common garden experiment. We find quantitatively distinct differences in the evolutionary

Abstract:
Colonial breeding is widespread among animals. Some, such as eusocial insects, may use agonistic behavior to partition available foraging habitat into mutually exclusive territories; others, such as breeding seabirds, do not. We found that northern gannets, satellite-tracked from 12 neighboring colonies, nonetheless forage in largely mutually exclusive areas and that these colony-specific home ranges are determined by density-dependent competition. This segregation may be enhanced by individual-level public information transfer, leading to cultural evolution and divergence among colonies.

Abstract Animals have evolved sophisticated immune systems to distinguish self from infectious non-self. In addition, several groups of colonial marine invertebrates—animals such as sponges, corals, and sea squirts—have evolved allorecognition systems that allow them to distinguish between their own tissues and those other members of their species. Allorecognition phenomena occur when these animals, which live as encrustations on marine surfaces, grow into contact with each other. Compatible colonies fuse, while incompatible colonies reject and often compete for space. Although allorecognition

Functional specialization, or division of labour (DOL), of parts within organisms and colonies is common in most multi-cellular, colonial and social organisms, but it is far from ubiquitous. Several mechanisms have been proposed to explain the evolutionary origins of DOL; the basic feature common to all of them is that functional differences can arise easily. These mechanisms cannot explain the many groups of colonial and social animals that exhibit no DOL despite up to 500 million years of evolution.

Our data suggest that bat numbers have declined since the last surveys were made in 1983 and 1984. We located seven colonies, which held approximately 85-92% of the total population.

Abstract:
AbstractAscidians are sessile tunicates, that is, marine animals belonging to the phylum Chordata and considered the sister group of vertebrates. They are widespread in all the seas, constituting abundant communities in various ecosystems. Among chordates, only tunicates are able to reproduce asexually, forming colonies. The high regenerative potentialities enabling tunicates to regenerate damaged body parts, or the whole body, represent a peculiarity of this taxon. Here we review the methodological approaches used in more than a century of biological studies to induce regeneration in both solitary and colonial species. For solitary species, we refer to the regeneration of single organs or body parts (e.g., siphon, brain, gonad, tunic, viscera). For colonial species, we review a plethora of experiments regarding the surgical manipulation of colonies, the regeneration of isolated colonial entities, such as single buds in the tunic, or part of tunic and its circulatory system.

AbstractScleractinians, or stony corals, are colonial animals that possess a high regenerative capacity and a highly diverse innate immune system. As such they present the opportunity to investigate the interconnection between regeneration and immunity in a colonial animal. Understanding the relationship between regeneration and immunity in stony corals is of further interest as it has major implications for coral reef health. One method for understanding the role of innate immunity in scleractinian regeneration is in situ hybridization using RNA probes. Here we describe a protocol for in situ hybridization in adult stony corals using a digoxigenin (DIG)-labeled RNA antisense probe which can be utilized to investigate the spatial expression of immune factors during regeneration.
