In Central African tropical forests, the western lowland gorilla deposits most of the seeds it disperses in well-lit nesting sites that can favour seedling growth. The faecal matrix surrounding the seeds can act as a fertiliser and further enhance seedling development. This fertilisation effect had never been tested. Our research therefore aimed to determine whether seed deposition by gorillas (i) in faecal matter and (ii) in nest sites is advantageous for seedling development (growth rate and foliation rate) and survival (% of surviving seedlings). To assess the effect of the faecal matrix, seeds of Santiria trimera (Burseraceae), Chrysophyllum lacourtianum (Sapotaceae) and Plagiostyles africana (Euphorbiaceae) collected from gorilla faeces were sown in a nursery with and without a faecal matrix. Seedlings of Santiria trimera and Dacryodes normandii (Burseraceae) were established in nest sites and in closed canopy terra firme forest sites to assess the impact of seed deposition on seedling development and survival. The faecal matrix was observed to positively influence seedling development in the species studied, but showed no effect on survival. Regarding seed deposition sites, the development rates observed were two to ten times higher in the nest sites than in closed-canopy forest. This enhanced seedling development was positively correlated with canopy openness. In situ studies of seed germination, seedling growth and survival are needed to characterise the fate of gorilla-dispersed seeds more precisely. However, our results offer evidence that gorillas provide important directed dispersal services by depositing seeds most frequently in open canopy sites. [less ▲]

The European mink (Mustela lutreola) is one of the most threatened carnivores in Europe, with fragmented populations in Belarus. Russia and Romania, as well in south-western France and northern Spain. Many populations have become extinct recently, or are declining. We investigated mitochondrial DNA variation, using the complete D-loop region, and concentrating oil the west European population. The aim was two-fold: to use the genetic information to advise on the conservation of European mink, and to begin to understand their history through the Pleistocene. Captive breeding and re-introduction programmes are underway, so it is particularly vital to know whether the West European population should be treated separately. We find that European mink probably colonised from a single refugium after the last glaciation. West European populations may be fixed for a single haplotype. also suggesting a common origin. Despite this evidence for gene flow, following the precautionary principle we suggest that mink from the three geographically separate populations (Romania, Eastern and Western Europe) should be managed separately, for the moment.

The objective of this study was to evaluate whether introducing the condensed wheat distillers soluble ProtiWanze® (PW) in diets of beef cattle has an impact on feeding costs, health and production of the animals. PW by-product from a Belgian bio-ethanol plant which utilized only wheat without bran, is an acid (pH=4) liquid feed rich in energy (VEM= 1130) and protein (TP= 282 mg/kg DM). PW supplementation from 9 to 13% on DM basis has been tested in 4 suckler cows’ farms for 4 months in 2011 and 2012. In 2011, 2 BB (H1 and H3) and 1 Blonde d’Aquitaine (H2: 23 cows) herds were evaluated and in 2012, the Blonde d’Aquitaine herd was replaced by a third BBB herd (H4: 42 cows). Every month, animals’ health and production were checked by the mean of Body Condition Score, Ruminal Fill, Fecal Consistency, Undigested Fraction and Locomotion Scores determination, as described by Zaaier et al.(2001) and Sprecher et al.(1997). Ruminal fluid was sampled by a stomach tube (Ruminator®) on 5 cows for pH, redox potential (Methylene blue test) and protozoa assessment (optical microscopy). Reproduction performances of this 2 year’s-period were analyzed. Price of a diet containing the same amount of proteins brought by a mixture of 1/3 soybean and 2/3 canola meal was calculated to verify whether introducing PW reduced feeding costs. Whatever the concentration of PW used, no adverse effect has been observed concerning reproduction, production performance, ruminal pH. Feeding costs were reduced by 0.08 €/cow/day in 2011 and by 0.02 €/cow/day in 2012. This lower spared amount in 2012 is the consequence of the reduction in PW protein concentration while its price increased. Anyway, comparison has to take into account the energy brought by this CDS as it has been suggested by Petersen’s equation, which compares CDS price with soybean meal but also with maize price. Further argument to be considered, especially in BB, is the high PW palatability, its low ruminal filling value and better roughage digestion. [less ▲]

The objective of this study was to evaluate whether introducing the condensed distillers soluble (CDS) ProtiWanze® (PW) in beef cattle diets has an impact on feeding costs, health and production of the animals. PW, a by-product derived from a Belgian bio-ethanol plant which utilizes only branless wheat, is an acid (pH=4) liquid feed rich in energy (VEM= 1130) and protein (TP= 282 mg/kg DM). PW supplementation from 9 to 13% on DM basis was tested in 4 suckler cattle farms for 4 months in 2011 and 2012: In 2011, 2 Belgian Blue (BB) (H1 and H3) and one Blonde d’Aquitaine (H2) herds were evaluated and in 2012, H2 was replaced by a third BB herd (H4). Every month, the animals’ health and production were checked by means of Body Condition Scoring (BCS), Ruminal Fill (RF), Fecal Consistency (FC), Undigested Fraction (UF) and Locomotion Scores (LS). Ruminal fluid was collected with a stomach tube (Ruminator®) on 5 cows for pH, redox potential (Methylene blue test) and protozoa assessment (optical microscopy). Reproduction performances during these 2 years were analyzed. The price of a diet containing the same amount of proteins brought by a mixture of 1/3 soybean and 2/3 canola meal was calculated to verify whether introducing PW reduced feeding costs. [less ▲]

The main purpose of the researchwas to testwhether cumulative effects represent a common pathway to behavioral maladjustment for internationally adopted adolescents and controls. The findings of previous comparison and follow-up studies have been contradictory. The hypothesis was tested in an original multi-informant study with 74 adolescents: 40 adoptees and 34 controls. The analyses of the data provided arguments in favor of the existence of a common pathway for adoptees and controls. The accumulation of risk factors in the current characteristics of the adolescents and their family was significantly associated with behavioral outcomes of both adoptees and controls. Implications for research, policy and practice are discussed. [less ▲]

Previous studies (Lum et al., 2009; Tomblin et al., 2007; Ullman & Pierpont, 2005) have suggested that difficulties in the procedural learning system could contribute, in part, to the language difficulties observed in children with SLI. However, we have recently shown, with an adapted serial reaction time (SRT) task, that children with SLI are able to learn implicitly non-linguistic regularities (Gabriel et al., submitted). In this research, we wanted to determine whether children with SLI are able to learn an 8-elements probabilistic sequence into which irregularities are inserted. Assessing probabilistic sequence learning in children with SLI should help us to better circumscribe the language difficulties of these children [less ▲]

The study of procedural learning abilities in children with Specific Language Impairment (Procedural Deficit Hypothesis, PDH; Ullman & Pierpont, 2005) remains a relatively unexplored field of research. Since most evidence comes from studies using tasks which involve learning of sequenced patterns, research using other procedural learning paradigms (like motor adaptation tasks) is needed to further evaluate the PDH in children with Specific Language Impairment (SLI). Therefore, in this study, we examined the ability of children with and without SLI to learn, consolidate and generalize a mirror-tracing task, a paradigm that does not involve sequence learning and had never been used in SLI. Children with SLI and typical developing (TD) matched children participated in the study. Children with SLI were included if they scored below -1.25 SD of the expected normative performance in at least 2 language areas. Both groups had to trace ten 5-pointed stars seen only in mirror-reversed view in two learning sessions separated by a one-week delay. The transfer phase consisted in tracing a new figure. The time required to complete the tracing, and the number of errors committed were recorded. Full results will be presented and discussed during the presentation of the paper. [less ▲]
