Published: November 2022

A parental child-centered feeding approach is likely to keep children’s biological mechanisms activated while eating, protecting them in an obesogenic context. However, few feeding practice measures assess parents’ behaviors to guide and prompt children to identify and respond appropriately to their signs of hunger and satiety. We aimed to develop and study the reliability, validity, and measurement invariance of a new scale to assess parental feeding practices to promote children’s self-regulation of food intake. To pursue this aim, we conducted two descriptive, cross-sectional, online studies in Portugal in an online format; a total of 536 parents of 2- to 6-year-old children completed the evaluation protocol. Factorial analysis findings support the theoretical organization proposed for the scale. The confirmatory factorial analysis supported a first-order factor structure with two subscales, Prompting for eating self-regulation and Teaching about eating consequences, with eight items in total. Both scales presented good internal consistency and adequate temporal stability, with a significant, positive, and moderate relationship. The results showed metric invariance for the child’s sex. Both types of practices were positively correlated with the child’s enjoyment of food. Prompting for eating self-regulation showed negative associations with parents’ emotional lack of control, children’s satiety responsiveness, slowness in eating, and fussiness. Preliminary studies confirmed both the validity and reliability of the instrument and the adequacy of adopting a self-regulatory approach when assessing child-centered feeding practices. Combining this instrument with others that assess coercive practices can be beneficial to capture ineffective parents’ behaviors on children’s eating self-regulation.
Some ecological observations on the Purple Heron in the Camargue
Authors: Williams Graham 
Published: November 2022

L’histoire du Héron pourpré en Camargue, son cycle annuel, sa reproduction, son comportement alimentaire et son alimentation sont étudiés sur la base des observations de l’auteur en 1957 et d’après les données de la bibliographie.
Quoique nichant en Camargue depuis longtemps, le Héron pourpré semble y avoir augmenté depuis vingt ans et le nombre des couples nicheurs doit dépasser largement un millier.
Les Hérons pourprés arrivent en Camargue dès la fin mars, mais surtout en avril. Ils la quittent de juillet à septembre, la plupart en août. Les jeunes de l’année au moins s’envolent dans toutes les directions, mais rejoignent ensuite probablement l’Afrique tropicale, qui doit être le quartier d’hiver des oiseaux camarguais. L’hivernage en Camargue est exceptionnel.
L’espèce niche en petites colonies de moins de dix à plus de cent couples, généralement dans les roselières jeunes, pas trop denses. Le nid est une plateforme en tiges de roseaux d’un diamètre dépassant souvent un mètre et situé généralement de trente à cent vingts centimètres au-dessus du plan d’eau. La construction débute par le tassement des tiges sur place ; des roseaux sont ensuite souvent apportés de loin pour consolider l’édifice. La ponte a lieu dès fin avril, mais elle s’échelonne sur plus d’un mois. Dès l’âge de dix à douze jours, les poussins quittent souvent le nid pour des excursions dans le voisinage. Les fortes pluies semblent être le facteur principal de mortalité parmi les poussins. Le nombre d’œufs par ponte varie selon les endroits et les saisons et semble avoir été particulièrement faible en Camargue en 1957 (Moyennes pour la France (Mayaud) , 5,1 ; pour la Suisse (Manuel), 4,1 ; pour la Camargue 1957 (Williams), 3,3).
Le Héron pourpré chasse à l’affût le long des fossés ou dans la zone de bordure des marais ouverts. Poissons, grenouilles et de grands insectes aquatiques sont les proies principales. Les prairies irriguées attirent les Hérons à la recherche des courtilières, tandis que les rizières ne sont que rarement visitées. Dans les eaux saumâtres la proie principale est l’anguille.
L’analyse des estomacs et pelotes de poussins montre une prépondérance d’insectes (Coléoptères et Courtilières), moins de Poissons et peu de Grenouilles. Il est probable que des poussins plus âgés reçoivent davantage de poissons. Les poussins sont nourris pendant toute la journée, mais surtout le matin et vers le soir.
Un facteur de mortalité mal connu, l’asphyxie par gaz toxiques naturels au parc national Albert, Congo
Authors: Verschuren Jacques 
Published: November 2022

The numerous instances of the destruction by volcanic gases of large numbers of mammals, birds, reptiles, amphibia and insects in the Albert National Park in the Congo are reviewed by the author on the basis of observations made by him between 1957 and 1961.
Such asphyxiations occur at definite places which are known by the vernacular name of «masukus», meaning places of gas discharge, and the characteristics of these areas and the lists of dead animals found in them are given.
The gas responsible for the killings is carbon dioxide ; and the fact that the discharge is not continuous increases the effectiveness of these «natural gas chambers» as animals would soon learn to avoid a place of continuous discharge. Experiments carried out with domestic animals show that immobilization occurs with great rapidity, and that these CO2 pockets are lethal even to birds and bats which fly into them.
The «masukus» are not completely sterile as some plants manage to thrive in them. They have undoubtedly played a role in the building up of some fossil deposits, and it is interesting to speculate that they may well account for the legend of «elephant cemeteries» which persists in so many parts of Africa.
Les migrateurs paléarctiques au Sénégal. II. Passereaux et synthèse générale
Authors: Morel Gérard J. , Roux Francis 
Published: November 2022

This article reports the results of several years of faunistic and ecological research on palearctic migratory birds in Senegal. Most of the data was collected in the north portion of the country in full Sahelian zone. The major environments studied are described and the representative migratory elements of their avifauna indicated.
Each species is then considered separately under several aspects : systematic, dates of presence, habitat, relative abundance and diet when known. The banding information has been included.
The number of palearctic species «wintering» in Senegal is considerable : 150, or over a third of the total known avifauna of the region. It appears from this fact, that wintering in West Africa is qualitatively comparable to what it is in East Africa, regarded till now as a privileged zone.
Several unknown or rarely mentionned species of tropical Western Africa have been observed and collected. Among them : Porzana porzana, P. pusilla, P. parva, Burhinus oedicnemus, Larus audouinii, Otus scops, Caprimulgus ruficollis, Locust ella tusci-nioides, L. naevia, Acrocephalus schenobaenus, Luscinia svecica, Emberiza hortulana.
Emphasis is placed on the particularly abundant species : Ciconia ciconia, Anas querquedula, Milvus m. migrans, Philomachus pugnax, Limosa limosa, Streptopelia turtur, Motacilla flava, etc., as well as those with a still ambiguous status : Ixobrychus m, minutas, Plegadis falcinellus, Gallinula chl. chloropus, Glareola pratincola, Clamator glandarius, etc. During their migrations, while some species only rapidly cross the region studied : Cuculus canorus, Apus apus, Merops apiaster, Sylvia borin, Phylloscopus trochilus, Muscicapa striata, Ficedula hypoleuca, Saxicola rubetra, etc., others are absent only during a period equal to or under two months, Tringa ssp, Philomachus pugnax, Lanius senator, etc., ; others finally leave representatives all year round : Limosa limosa, Himantopus himantopus, Hippolais pallida, for exemple.
Banding results and morphological examination tend to show that most of the migrants come from northern and western Europe. However the contribution of palearctic Africa is not to be underrated : Falco biarmicus erlangeri, Buteo rufinus cirtensis, Capri-mulgus aegyptus saharae, Oenanthe oe. seebohmi, etc. Some species originate from eastern Europe or Asia : Circus macrourus, Tringa stagnatilis, Oenanthe isabellina, and others come from Greenland : Charadrius h. hiaticula, Oenanthe oe. leucorhoa.
Local banding revealed, on the other hand, that some species regularly return to the same wintering sites. This is the case for Motacilla alba, Hippolais pallida, Sylvia cantillans, Phylloscopus collybita and Phoenicurus phoenicurus.
Etude comparative de la résistance à la chaleur d’Uromastix acanthinurus et de Varanus griseus
Authors: Grenot Claude 
Published: November 2022

Field experiments have been conducted in the Algerian Sahara to test the ability of two lizards of about the same size Uro-mastix acanthinurus and Varanus griseus, to regulate their body temperature when exposed to sun in conditions preventing any behavioral regulation.
Both species are able, through increased ventilation, to prevent a too rapid increase of body temperature, but physiological regulation is more efficient in Varanus than in Uromastix. The Sand monitor is able, even in the hottest part of the day, to keep its body temperature at a more or less constant level (42° C) for up to 4 hours, in contrast with Uromastix which is not able to do this. Young Uromastix are able to resist heat stress much better than adults.
Notes éthologiques sur quelques Carnivores malgaches : le Galidia elegans I. Geoffroy
Authors: Albignac Roland 
Published: November 2022

In Madagascar, Galidia elegans tills an ecological niche similar to those occupied by the mongooses of the African continent. They have a roughly similar diet and share the same behaviour pattern of hurdling hard objects between their hindlimbs with species of Herpestes, Atilax, Mungos and Helogale.
On the other hand, Galidia elegans appears to be more arboreal and less social than most mongooses. Unlike many Viverrids it has only one young a year.
Observations éco-éthologiques sur les lémuriens malgaches du genre Hapalemur
Authors: Petter J-J , Peyrieras A. 
Published: November 2022

Au cours de deux missions récentes à Madagascar, une étude du genre Hapalémur a pu être entreprise sur le terrain. Elle a été complétée par l’observation d’animaux captifs à Madagascar et au Laboratoire d’Ecologie du Museum National d’Histoire Naturelle à Brunoy.
Deux formes ont été reconnues, dont la répartition géographique, l’habitat et l’alimentation dans la nature diffèrent mais dont la locomotion, les postures, le rythme d’activité, la vie sociale, les moyens d’intercommunications, la reproduction et le comportement en face des prédateurs semblent assez comparables.
Des élevages en captivité d'Hapalémur griseus ont pu montrer les possibilités d’adaptation de ces animaux et ont permis de les comparer à Lemur macaco, d’étudier leurs moyens d’intercommunication et d’observer leur reproduction.
Cette étude permet de mieux différencier les Hapalémur des autres Lémuriens malgaches. Ils en diffèrent principalement par les caractères du milieu qu’ils fréquentent, leur réaction de fuite, leurs postures, leur locomotion, leur régime, leur vie sociale, leurs moyens d’intercommunication et leur reproduction. Ces caractères permettent probablement une meilleure défense contre les prédateurs.
Répartition de la végétation dans la savane pré-forestière
Authors: Duviard Dominique , Dugerdil Marc , Bonvallot Jacques 
Published: November 2022

The vegetation of the Lamto area has been studied along transects linking the gallery forest to the savanna plateau. The counting strips, 20 metres wide and 200 to 460 metres long, were subdivided into a succession of quadrats 20x20 m. In each of these quadrats trees and shrubs were counted and the grass layer sampled. Results are shown on folding pages 1 to 5.
Within the study area four different types of savanna are found, grass savanna, shrub savanna, tree savanna and savanna woodland. The shrub savanna in predominant. The relationships between these vegetation types, topography and soils are discussed.
Le peuplement avien. Essai d’étude quantitative.
Authors: Thiollay Jean-Marc 
Published: November 2022

The avifauna of the Lamto area has been studied during a two year period. 263 species have been recorded and the habitat preferences, diet, breeding periodicity and fecundity of the major species studied. 43 % of the birds are forest species. Only very few of them are abundant, eight species accounting for half of the total numbers of birds counted. Migrants are numerous in the savanna ; one third of them are palearctic passerines, while local migrants are represented mainly by non-passerine families. 90 % of the species are more or less omnivorous, but all migrants show a distinct preference for insect food. Breeding occurs throughout the year : among the 124 commoner species, 62 % breed during the rains and 23 % during the dry season. Fecundity is low and the same female seldom reproduces twice during the year.
Counts have been made regularly on a line-transect 12.5 km long and 40 m wide. Monthly variations of numbers and biomasses are given in tables V and VI. Contrary to the situation further North, seasonal variations are small in the forest-savanna mosaic. There are two peaks : the first one, from February to May, corresponds to an influx of northern migrants ; the second, from July to September, is attributable to the natural increase of sedentary species and an influx of fruit-eaters. Minimum values are found in December, at the beginning of the dry season. The average yearly biomass of birds for the Lamto savanna is in the order of 1 kg/ha (fresh weight).
Introduction
Authors: Bourlière François 
Published: November 2022

The Sahel (dry thornbush savana) of Africa is one of the simplest tropical ecosystems. Its biotic community comprises a small number of plant and animal species and its climate is characterized by a single and short rainy season followed by a long period of drought. This ecosystem has not been drastically modified by man, except for the replacement in some areas of most large wild ungulates by domestic species.
The «Ferlo septentrional» in Northern Senegal (fig. 1) has been selected as a suitable area for long-term ecological studies, as its vegetation and fauna were reasonably well known and the proximity of the Richard-Toll field station (tig. 2) afforded logistic facilities. Furthermore the region is only partially inhabited by nomadic cattle herders (Fulani), whose herds have an average standing crop biomass of about 30 Kg/ha (fresh weight). This facilitates comparison of «wild » and «managed » components of the same ecosystem type.
A field base has been established at Fété Olé (fig. 3), close to the one square-kilometer reference quadrat, located outside the area regularly visited by fulani cattle herds. All the data presented in this first set of papers have been gathered within this quadrat, or in the 100 Km2 area surrounding it.
The ORSTOM/SAHEL Project forms part of the French contribution to the International Riological Programme (PT Sec¬ tion) and the support given by the ORSTOM (French Overseas Research Organization) is gratefully aknowledged. Investigations will be continued for a further two years, and progress reports
Contamination des milieux aquatiques par les résidus des produits phytosanitaires
Authors: Heurteaux Pierre , Mestres R. , Vaquer André 
Published: November 2022

Results are given of a two year study on the pollution by pesticide-residues of the aquatic environment in the Camargue.
The agricultural techniques employed, notably in rice-growing (intensive and extensive irrigation, chemical control of pests) threaten the whole aquatic environment in the Camargue with pollution, particularly the lakes situated in the «Réserve Natu- relie Zoologique et Botanique ». These pollutants originate from the Rhône river and from agricultural treatments using herbicides and insecticides.
Herbicide studies have proved difficult to conduct and results obtained to date are too fragmentary to allow a clear interpretation.
More detailed results on insecticides show that water pollution is still very low but that the accumulation of organo-chlorides at the different trophic levels of the ecosystem presents a real threat.
The pesticides most frequently recorded are alpha HCH (BHC) (Rhone origin) and gamma HCH (Rhone and agricultural origin). Detectable doses of DDT are less frequently recorded. Other residues are only suspected in water because of their presence in animal tissues (dieldrin). Lastly, others are only revealed during the period when crops are treated (organophosphates and especially parathion) or as a result of very particular circumstances (polychlorocamphene) .
The presence of polychlorobiphenyls in the environment raises a special problem. They probably have a mixed origin (Rhone and commercial types of agricultural pesticides where they serve as an adjuvant). These very stable organochlorides are accumulated at relatively high rates in sediments as well as in aquatic plants and animals, and present a real danger to the conservation of natural habitats.
The conciliation of agriculture and nature conservation in the Camargue is dependent on two conditions : return into the Rhone of all run-off water from crops, at present discharged into the «Etang du Vaccarès », and research into cultural methods which produce less pollution than those in current use.
La nidification des flamants en 1970-1971
Authors: Johnson Alan 
Published: November 2022

En 1970 et 1971, malgré le faible nombre de couples nicheurs, les Flamants ont connu un bon succès de reproduction : 280 jeunes élevés en 1970 et 1 500 environ en 1971. En 1970, il est fort probable qu’une autre colonie plus importante, probablement en Afrique du Nord, ait abouti à une réussite d’élevage puisque un certain nombre de jeunes de l’année ont été observés en Camargue avant le départ de nos jeunes.
L’îlot de nidification choisi durant ces deux années n’a pas été utilisé par les Flamants depuis trente à quarante ans. Nous proposons que cette localité reste anonyme et l’appelons ic,i l’Etang A. Les flamants y ont cohabité avec plusieurs espèces de laro-limicoles, y compris les Goélands. A l’écart des intrusions humaines les colonies ont pu jouir de la tranquillité qui leur est nécessaire et les deux saisons de reproduction se sont déroulées d’une façon régulière.
Aucun baguage n’a été effectué.
Dynamique de certains groupements de collemboles
Authors: Poinsot-Balaguer Nicole 
Published: November 2022

Study of the dynamics of Collembola groups in the Camargue illustrates well the role of abiotic factors (content of water and salt). In the sansouire, the Thero-Brachy podium which has a very low salt content, supports by far the richest association, both in qualitative and quantitative terms. It contains not only exclusively deltaic species, but also so-called «provençales» species. In the more saline Salicornietum, the Collembola populations show only a simple impoverishment compared with the Thero-Brachypodium. All species found in the Salicornietum are also present in the Thero-Brachypodium. Similarly, the Arthrocnemetum supports lower populations that the other two areas. Salt plays a primary role in the distribution of Collembola, though its effect is somewhat counterbalanced by the presence of stretches of water. In fact, the areas of Arthrocnemetum situated at the edge of temporary pools are slightly richer in species than those areas which are never covered by water. Halophilic Collembola are not present but there are eurytopic species which can withstand very high salt concentrations. These observations support those made by Palissa in saline biotopes on the Baltic coast.
The zonation of Collembola populations around the brackish flats in the Camargue may be extended to all inundated and littoral zones. Water surfaces and edges are populated by thalas-sobiontic or hygrophvllic species. As one moves away from these areas, these first species disappear and are replaced by pioneer species, generally ubiquitous in nature, which are characteristic of the neighbouring biotopes which are always present behind the instable zones.
Déplacements saisonniers des Fous de Bassan de l’ile Bonaventure (Canada)
Authors: Moisan Gaston , Scherrer Bruno 
Published: November 2022

Plus de 11000 jeunes Fous de Bassan (Sula bassana) ont été bagués sur l’Ile Bonaventure (48°3’N., 64°1’W., Province Québec) et 417 retours ont été enregistrés et analysés. La distribution géographique des retours indique que la voie de migration des Fous de Bassan est exclusivement côtière. En automne, peu après la fin de la reproduction, juvéniles, sous-adultes et adultes partent ensemble vers les latitudes chaudes, au moment où leurs proies migrent vers le large et avant que les conditions météorologiques soient très défavorables. La migration vers le sud, très régulière et progressive s’effectue à la vitesse de 15 à 20 milles par jour. Les juvéniles et les sous-adultes atteignent généralement le Golfe du Mexique alors que les adultes ne dépassent pas habituellement la côte Est de la Floride. La migration de retour qui s’amorce dès février chez les adultes, près d’un mois plus tard chez les sous-adultes et deux mois chez les juvéniles, est en moyenne plus rapide (35 à 70 milles par jour) que celle d’automne.
Les adultes arrivent sur les sites de nidification dès la mi-avril quand les conditions météorologiques sont encore très sévères et quand les tout premiers bancs de poissons de surface apparaissent au large des côtes. Cette arrivée précoce des adultes s’explique par la durée de l’incubation (44 jours) et par la nécessité d’élever les jeunes quand la nourriture est abondante. Les sous-adultes et surtout les juvéniles arrivent dans les quartiers de reproduction quand le climat s’adoucit et quand le poisson abonde.
Les grands mammifères du Parc National de Taï, Côte d’ivoire
Authors: Monfort Alain , Monfort Nicole 
Published: November 2022

The Taï forest in Western Ivory Coast is the last sizeable refuge of a number of endemic Western African mammals, three of which being on the IUCN list of endangered species.
Ten species of primates have so far been observed in this area : 2 prosimians, 3 species of guenons (Cercopithecus) , 3 species of Colobus monkeys, one mangabey (Cercocebus ) and the Chimpanzee. The Diana monkey is the most frequently observed species of guenons ; it often forms mixed troops with red, and black and white, colobus monkeys.
Fifteen species of ungulates have been recorded, including pigmy hippopotamus, zebra duiker, Jenkink’s duiker and five other species of genus Cephalophus.
