Abstract:

AbstractQuantifying interconnected performances of the modules in a colonial organism (feeding, sexual reproduction, rejuvenation, dormancy) into an integral picture enables studying functional dynamics and resource allocation at different levels – from module to population. Testing this approach on the common boreal-Arctic bryozoan Cribrilina annulata in the White Sea, we describe its life history, comparing colonies on two algal substrates with contrasting size and lifespan. Colonies living on kelps were much larger and had a higher proportion of dormant zooids, whereas the percentage of rep

Abstract:

Sexual and asexual reproduction and associated population dynamics were investigated in the colonial ascidian Didemnum rodriguesi Rocha & Monniot, 1993 (Didemnidae) in southern Brazil. Investment in sexual (production of new individuals) and asexual (colony growth) reproduction was compared between seasons. Permanently marked quadrats were repeatedly photographed to measure changes in colonies. Eggs and larvae were counted monthly in collected colonies. This species alternates seasonally between sexual (summer) and asexual (winter) reproduction. In summer, colonies were smaller, brooded eg

Abstract:

(Uploaded by Plazi for the Bat Literature Project) The genetic structure of eight summer and four winter colonies of the migratory bat (Tadarida brasiliensis mexicana) was examined to test the hypotheses that migratory populations are genetically distinct and that maternity colonies are composed of bats from genetically differentiated breeding colonies. Samples from seven of the summer colonies included only lactating females that were resident with their young in maternity roosts. Samples from winter colonies included adult males and adult females. Males and females were analyzed separately.

(Uploaded by Plazi for the Bat Literature Project) Plecotus auritus, a small, gleaning bat species, lives in small, isolated summer colonies in which both males and females show a high degree of natal philopatry.

It has been suggested that inbreeding is avoided because mating occurs during autumnal and spring swarming at hibernation sites.

Whereas many photosymbiotic didemnids are thought to be sexually mature throughout the year in the tropics, sexual reproduction of the same species in subtropical waters may be limited to spring and summer. The subtropical winter may be too cold for gonad formation. A histological study

Held on the encouragement of initiative in African society, the conference devised a policy framework of community development based on a model of mass education long favoured by Arthur Creech Jones, secretary of state for the colonies and former chair of the Fabian Colonial Bureau (FCB).

Abstract:

Abstract Commercial honey bee (Apis mellifera L.) colonies significantly contribute to agricultural productivity through crop pollination. Almond production requires the most colonies because there are more than a million acres of orchards that require cross-pollination for nut set. With the rising costs of managing and transporting colonies to almond orchards combined with the high colony losses beekeepers routinely experience, we asked if renting colonies for almond pollination was profitable. We conducted a longitudinal study on 190 colonies from their establishment in April until they were

Abstract:

The incidence and spatial distribution patterns of Caribbean Yellow Band Disease (CYBD) on the important frame-builder coralMontastraea faveolatawere assessed by counting, tagging, and mapping all diseased and healthy colonies for one year in each of three 100 m2quadrats on two inner, mid-shelf, and shelf-edge reefs off La Parguera, Puerto Rico. Healthy colonies were checked every month from January to December of 2009 to monitor disease spread within each quadrant. Incidence increased significantly from winter (0.7±0.8% SE) to summer (1.5±1.1% SE,n=23, Sign Test;Z=2.40;P=0.01). Mid-shelf reef

Murres and puffins ranged 100 km or farther from all colonies in summer, but most instrumented birds had abandoned breeding attempts and their movements likely differed from those of actively breeding birds.

Abstract:

Pheidole desertorumcolonies are large for the genus; the number of adult workers in established colonies ranges from 2,460–24,814. They are nocturnal during summer and are predators and scavengers on arthropods. Both minor and major workers forage, although foraging by majors appears to occur primarily when food is abundant. Young major workers may function as repletes. The adult major/minor worker ratio varies greatly among colonies; much of that variance appears explained by colony size and marturity of adult colony reproductive broods. Most colonies produce reproductives each year and colon

First-year birds migrate south in autumn earlier than those from gannetries further north, many to waters off northwest Africa and some as far south as Senegal, while others move into Mediterranean Waters, perhaps more readily than juveniles from more northern colon

Abstract:

Honey bees balance colony populations against available food resources by adjusting brood rearing during nutritionally-stressed periods. Workers limit colony populations primarily through brood cannibalism of eggs and young larvae but often resume brood rearing when conditions improve. However, extended brood cannibalism reduces brood and removes brood signals that mediate brood rearing, such as E-β-ocimene, a volatile pheromone produced by eggs, young larvae, prepupae and ovipositing queens. We examined the effects of pollen supplementation on ocimene signaling in nutritionally-stressed colon

Both mono-infection either by N. apis or N. ceranae, and co-infection by both Nosema species, were found. There was a decrease in the percentage of Nosema infected colonies during the four-year study period. There were fewer colonies infected by N. ceranae, whereas the number of colonies with N. apis remained approximately at the same level during the study.

SummaryRecent advances in bird tracking technologies are revealing that migratory birds use temporal staging sites other than breeding and wintering areas, and these areas deserve conservation efforts. Eleonora’s Falcon Falco eleonorae is a long-distance migratory raptor that breeds colonially on islands and is considered a priority species for conservation. Anecdotal observations indicate that during the pre-breeding period, Eleonora’s Falcons stay in inland areas far away from the colonies, but, to date there are no detailed data concerning the connectivity between these areas and breeding c

To investigate this, parasite-free commercial Bombus terrestris audax colonies, which are used commercially for strawberry pollination, were placed into seasonal strawberry crops for either 6- or 8-week blocks across two key time periods, early spring and ear

Selection for three generations resulted in approx. 90% lower Varroa population growth in LVG than in HVG colonies. In addition, late summer Varroa infestation rates of brood and
