The revised IUCN protected area management categories: the debate and ways forward
Authors: Dudley Nigel , Parrish Jeffrey D. , Redford Kent H. , Stolton Sue 
Published: August 2010

AbstractThe global protected area estate is the world’s largest ever planned land use. Protected areas are not monolithic and vary in their purpose, designation, management and outcomes. The IUCN protected area category system is a typology based on management objectives. It documents protected area types and is increasingly used in laws, policy and planning. As its role grows, the category system must be reactive to opinions and open to modifications. In response to requests from members IUCN undertook a 4-year consultation and recently published revised guidelines for the categories. These made subtle but important changes to the protected area definition, giving greater emphasis to nature conservation, protection over the long term and management effectiveness. It refined some categories and gave principles for application. Debates during revision were intense and highlighted many of the issues and challenges surrounding protected areas in the early 21st century. There was a consensus on many issues including the suitability of different governance models (such as indigenous and community conserved areas), sacred natural sites, moving the emphasis of Category IV from habitat manipulation towards species and habitat protection, and recognition of legally defined zones within a protected area as different categories. However, there was considerable disagreement about the definition of a protected area, the appropriateness of some categories with extensive human use, the possibility of linking category classification with biodiversity outcomes, and recognition of territories of indigenous peoples. We map these debates and propose actions to resolve these issues: a necessary step if the world’s protected area network is to be representative, secure and well managed.
Is There an Age Pattern in the Treatment of AMI? Evidence from Ontario
Authors: Grignon Michel , Spencer Byron G. , Wang Li 
Published: August 2010

RÉSUMÉDans cet article nous analysons la probabilité pour un patient hospitalisé pour infarctus du myocarde de recevoir des traitements chirurgicaux, puis nous mesurons les changements dans le temps de cette probabilité et cherchons à savoir si l’âge du patient joue sur la probabilité. Nos estimations, fondées sur des données administratives incluant tous les séjours dans les hôpitaux de soins aigus de l’Ontario pour certaines années entre 1995 et 2005, font état d’un profil par âge marqué et stable dans le temps dans la diffusion de la technologie médicale. Nos résultats montrent que ceci est robuste à l’inclusion de contrôles pour la plus forte fréquence de co-morbidités chez les patients âgés ainsi que pour les effets de pratiques propres aux hôpitaux.
THE PBEOBAL CHJAEY ORGAN OF THE ENTEBOPNEUSTA: 11. The Preoral Ciliary Organ of the Enteropneusta: its Occurrence, Structure, and possible Phylogenetic Significance
Authors: Brambell F. W. Rogers , Cole H. A. 
Published: August 2010

SummaryThe preoral ciliary organ on the base of the proboscis of Saccoglosstis cam‐brensis, sp. n., is described in detail. It is in the form of a continuous band of cells bearing long cilia bounding a U‐shaped groove. The surrounding epidermis, and that of the groove itself, is provided with shorter cilia. An account is given of the cytological structure of the component cells. Cells, which from their structure are thought to be sensory, are numerous in the walls of the groove.Similar organs are recorded in Saccoglossus kowaievskyi Agassiz, S. irihacensis Kapelus, Harrimania kupfferi von Willemoes‐Suhm, Olossobalanus minutus Kowalevsky, Balanoglossus carnosus Willey, B. capensis Gilchrist, and Ptychodera flava Eschscholtz. The occurrence, possible function, and homology of this organ are discussed. The evidence available supports the suggestion that the preoral ciliary organ of the Enteropneusta is homologous with the preoral pit and wheel‐organ of Amphioxus and with the hypophysis of the Craniata.We wish to take this opportunity of expressing our thanks to Professor J. P. Hill, F.R.S., Professor C. J. van der Horst, and Professor W. Garstang for advice and criticism. We are indebted also to Professor C. J. van der Horst for the specimens of S. inhacensis, to Professor J. H. Orton for the opportunity of examining specimens of Ptychodera sp. and Olossobalanus minutus, and to the Director of the British Museum (Natural History) and Miss Hastings for access to the collections at South Kensington. The expenses of this research were defrayed by a grant to one of us (F. W. R. B.) from the Government Grant Committee of the Royal Society, for which we wish to express our thanks.
The Systematics of the Crustacean Genus Callianassa.
Authors: Gurney Robert 
Published: August 2010

Summary.Beyond the somewhat obvious deduction that the present subdivision of the genus is ill‐founded, it must be admitted that no clear conclusion can be drawn from the facts adduced. All that is claimed is that they justify an appeal to those to whom specimens are available of species not adequately described to re‐examine them and provide the information upon which a revision of the genus may be founded.
On a Plasmodium (Plasmodium relictum var. spheniscidæ, n. var.), observed in four species of Penguins
Authors: Fantham H. B. , Porter Annie 
Published: August 2010

Summary.An illustrated account is given of Plasmodium relictum n. var. spheniscidæ from the King Penguin, Aptenodytes patagonica, from South Georgia, the Black‐footed Penguin, Spheniscus demersus, from Saldanha Bay, South Africa, the Yellow‐crowned Penguin, Eudyptes antipodes, from Foveaux Strait, New Zealand and the Rock‐hopper Penguin, Eudyptes crestatus, from Gough Island.The variations in the morphology and in the range of dimensions of the Plasmodium from each of the hosts are described and illustrated. Detailed comparison shows that the same organism is present hi all of them.The effects of Plasmodium relictum var. spheniscidæ on the hosts are described in some detail, counts of infected erythrocytes and of parasites are given and the effect of alterations induced in organs of one Black‐footed Penguin are discussed. The parasite level in the different hosts is noted.The identity of the Plasmodium from the four species of Penguin is discussed in some detail, especially in view of the wide distribution of Plasmodium relictum Grassi and Feletti both geographically and in the number and variety of its hosts. Various morphological and physiological strains of P. relictum are noted and induced morphological differences by passages to unusual hosts are considered. The conclusion is reached that a strain or morphological variety of P. relictum is present in Penguins, for which the name Plasmodium relictum n. var. spheniscidæ is proposed.The low gametocyte level of P. relictum var. spheniscidæ in all the hosts seems to indicate that it may be approaching natural agametogony, and so may be on the way to self‐extermination.Tolerance and age‐immunity of hosts and possible susceptibility and immunity among Culicine mosquitoes in relation to avian malaria are briefly noted.The economic importance of avian Plasmodium in general, and possibly of Plasmodium relictum var. spheniscidæ is briefly indicated.
Tne Behaviour of Hydra in Response to Gravity.
Authors: Ewer R. F. 
Published: August 2010

Summary.1. Buds of Hydra vulgaris immediately after separation from the parent migrate upwards towards the water surface. This reaction is a negative geotaxis, and not a response to a gradient in oxygen concentration; it takes place in water of any oxygen concéntration.2. Hydra is known to be photopositive. The gravity reaction of buds is much more strongly affected by light coming from below than by light coming from the side. Animals which have been grown for two generations in bottom light behave in the same manner as normal animals from stock cultures. This effect of bottom light is discussed in terms of the known mechanism of the animal's light reaction, and it is concluded that no new complexity in type of response or in neuromuscular organization need be postulated to account for it.3. An increase in carbon dioxide content of the water could not be shown to have any significant effect on the strength of the gravity reaction of buds, but evokes negative geotaxis in adult Hydra. Neither an equal lowering of pH by hydrochloric acid nor a reduction in the oxygen concentration has any affect.4. The gravity response of buds lasts for at least three days after separation from the parent.5. If a freshly separated bud is given food it ceases its upward migration.6. Walking of buds is fastest at about 22°C. Abnormalities in locomotion begin to appear at slightly higher temperatures, and at 26°C. walking stops.7. In upward migration the orientation to gravity is direct, without trial movements.8. The gravity reactions described are of biological significance. That of buds acts as a method of distribution and prevents local overcrowding. The response evoked in adults by carbon dioxide serves to bring them up to the surface when there is likely to be a shortage of oxygen lower down.
Observations on some natural epizootics of the trematode Polystoma integerrimum among tadpoles of Rana temporaria temporaria
Authors: Savage R. Maxwell. 
Published: August 2010

Summary.A quantitative study has been made of seven natural epizootics of Polystoma integerrimum in the tadpoles of Rana temporaria. About 4,000 parasites have been counted in about 1,000 tadpoles, in five ponds in one year, and in two in another, besides some additional observations in other ponds.Wide differences exist between the epizootics, but a general plan can be seen in all. The eggs laid by the adult fluke hatch at two main periods—one at the end of April or beginning of May. and the second about a month later. Some of the larvae which hatch from these eggs (the primary larvae) become neotenic larvae. These lay eggs which hatch in July (secondary larvae).In some ponds, all tadpoles metamorphose in June. The neotenic cycle in these ponds is therefore abortive, because by the time the secondary larvae hatch, there are no tadpoles. Infestation is secured in these ponds by the presence of primary larvae, particularly those of the second brood. In other ponds, many tadpoles can be found in July or August, and they become infested with secondary larvae, even if they have been relatively free from the parasites up to this date.There are large losses of parasites throughout the season, and it seems important for the species that some larvae should enter the tadpoles as near to the date of metamorphosis as possible, not only because the gill chamber is not a very safe location, but because there is a high mortality among tadpoles, due to many causes. Late infestation short‐circuits tadpole mortality. It is, indeed, suggested that it is late infestation rather than mere multiplication which is the chief function of the neotenic cycle. The life history of the fluke is so efficient that the parasite maintains its existence even though it lays fewer eggs than the host.The parasites appear to be without deleterious effect on the tadpoles, which are just as large when parasitized as when free from the flukes.At the early stages of infestation, there is a tendency for the larger tadpoles to have more parasites than the smaller ones, which are often free from the larvae.Tadpoles are not, in nature, normally infested until well after the stage when they have external gills. Even the rudiments of these have disappeared before infestation begins. Only one tadpole in all the collections was found to be infested while still bearing external gills.The parasites are not distributed among the tadpoles at random. There is a tendency for a tadpole to be either heavily infested, or else to be without the parasites, intermediate states being relatively rare.
A radiographic study of the passage of the blood through the heart in the frog and the toad.
Authors: FOXON G. E. H. 
Published: August 2010

SUMMARY.This paper is a further contribution to the study of the mode of action of the amphibian heart and gives an account of radiographic studies on the hearts of the frog and toad, Rana temporaria and Bufo bufo in which a radio‐opaque medium (thorotrast) injected through the left pulmonary vein into the left atrium has been followed in its course through the heart by means of rapid serial radiographs (approximately 3 per second).The results show that although blood from the left atrium (represented by the thorotrast) will, at ventricular diastole, come to occupy the left side of the ventricle at systole it is propelled towards the base of the conus where it mingles to a very great extent with the blood from other parts of the ventricle. The radiographs also show that the thorotrast obtains access to both sides of the conus and also to all three arterial roots on both sides.The evidence brought forward supports the earlier results obtained by similar injections of indian ink made by Vandervael (1933) and by Foxon (1948).A brief review of the problem of the mode of action of the heart of the frog is given and it is shown that most recent authors favour the view that there is little, if any, selective distribution of the blood in frogs and toads.
Change in status of the bridled guillemot after ten years*
Authors: SOUTHERN H. N. 
Published: August 2010

SUMMARY.A re‐survey of the distribution of the bridled form of the common guillemot, Uria aalge, during 1948‐50 has shown that in the ten years since the first survey was made, four colonies have decreased significantly in percentage of bridled birds and one has increased. The total number of colonies for which satisfactory comparisons were obtained was only eighteen. Discrepancies between observers made it necessary to accept only those counts which had been checked by other observers. This result is not statistically significant, but various facts suggest that a decrease in bridled birds is in progress and it is certainly worth continuing the investigation at ten year intervals.
