Abstract:
The purpose of this study is to examine the use of an accounting system using Microsoft Excel, the reliability of the accounting system used previously as well as the factors that influence the successful implementation of the Acosys software-based accounting information system at PT Ladfanid Konsultindo Batam. In implementation, in Microsoft Excel presenting financial statements, especially for trading and manufacturing companies in the calculation of cost of goods sold, there must be a classification beforehand because Microsoft Excel does not have a special menu in the presentation of purchases and sales so that there are several classifications in different sheets. The accounting system used today is Acosys, which is an accounting system that is more adequate and reliable than using Microsoft Excel. Acosys can be categorized as a complex system in preparing financial statements because it has features that can be used according to company needs. every transaction that has been inputted automatically all kinds of reports relating to finance can be accessed quickly as needed. What is rarely owned by other software but owned by Acosys is that Acosys software can be used forever without additional costs for updating.

Abstract:
e17501 Background: Coordination of care has grown in importance with the advent of new modalities of treatment requiring specialized expertise. In cancer care, multidisciplinary approaches have shown improvements in quality of care and patient satisfaction. Tumor boards provide a mechanism for improving coordination of care. We evaluated physician and practice characteristics that predict frequency of tumor board attendance. Methods: This cross-sectional study utilizes data obtained by surveying physicians of a population-based sample of women with incident breast cancer. Physicians were queried regarding tumor board attendance, specialty (medical oncologist [MO], radiation oncologist [RO], surgeon indicating that the hospital at which most breast cancer surgeries are performed has an American College of Surgeons accredited program [ACOSSg] and surgeon without such affiliation [non-ACOSSg]), physician characteristics (gender, race, teaching involvement, patient volume, number of offices, ownership interest), and practice setting (practice type, size, reimbursement). Univariate, bivariate, and multivariate analyses were performed for the dependent variable characterizing provider report of frequency of tumor board meeting attendance. Results: Most surveyed physicians (83%) report attending tumor board weekly (58%) or monthly (25%). Weekly participation was reported by 63%, 92%, 47%, and 32% of MOs, ROs, ACOSSgs, and non-ACOSSgs (p < 0.01). Specialty and higher patient volumes are significant predictors of more frequent attendance, after adjustment for practice size and type. In comparison to the most prevalent specialty category (low volume ACOSSgs), high volume MOs attend more (p = 0.01), and low volume non-ACOSSgs attend less frequently (p = 0.00). Conclusions: Tumor board attendance implies increased participation in multidisciplinary care, but specific subsets of providers are less frequent users. This not only has implications for choosing providers, but also for efforts to increase attendance. Tumor board agendas and formalized institution wide policies could be designed to further engage low frequency attendees as a means to promote multidisciplinary care and improve health outcomes.

Abstract:
Abstract Regeneration is rare in mammals, but spiny mice (Acomys spp.) naturally regenerate skin and ear holes. Inflammation is thought to inhibit regeneration during wound healing, but aspects of inflammation contribute to both regeneration and pathogen defense. We compared neutrophil traits among uninjured, regeneration-competent (Acomys: A. cahirinus, A. kempi, A. percivali) and -incompetent (Mus musculus: Swiss Webster, wild-caught strains) murids to test for constitutive differences in neutrophil quantity and function between these groups. Neutrophil quantity differed significantly among species. In blood, Acomys had lower percentages of circulating neutrophils than Mus; and in bone marrow, Acomys had higher percentages of band neutrophils and lower percentages of segmented neutrophils. Functionally, Acomys and Mus neutrophils did not differ in their ability to migrate or produce reactive oxygen species, but Acomys neutrophils phagocytosed more fungal zymosan. Despite this enhanced phagocytosis activity, Acomys neutrophils were not more effective than Mus neutrophils at killing Escherichia coli. Interestingly, whole blood bacteria killing was dominated by serum in Acomys versus neutrophils only or neutrophils and serum in Mus, suggesting that Acomys primarily rely on serum to kill bacteria whereas Mus do not. These subtle differences in neutrophil traits may allow regeneration-competent species to offset damaging effects of inflammation without compromising pathogen defense.

Abstract:
Varios estudios nos muestran diferentes manifestaciones del acoso escolar, desde sus formas visibles como agresiones físicas o verbales a las más psicológicas y sutiles que son más peligrosas, ya que al pasar desapercibidas no pueden ser detenidas por la comunidad educativa. Se ha planteado averiguar cómo acosan los alumnos; si lo hacen de forma visible o directa, psicológica, a través de Internet, y/o utilizan otras formas como la sexual. Para deducirlo, se ha realizado un amplio estudio en La Rioja (España), a través de un cuestionario dirigido a 348 alumnos de la ESO, cuatro grupos de discusión con padres y alumnos de la ESO y entrevistas dirigidas a treinta profesores. Los resultados muestran que la forma más común de acoso entre alumnos riojanos es la psicológica y en concreto, reírse de sus víctimas. Además todos los participantes en las técnicas cualitativas están de acuerdo en que los alumnos riojanos acosan a menudo por Internet. En ambos casos, las chicas tienen más protagonismo, lo que hace plantearnos la necesidad de poner en práctica más programas de igualdad en los centros educativos, además de formar e informar a la comunidad educativa sobre el complejo fenómeno del acoso y en el buen uso de las nuevas tecnologías, entre otros.

Abstract:
ABSTRACTSeven species of rodent, Paraxerus ochraceus, Tatera robusta, Saccostomus meamsi, Praomys (Mastomys) natalensis, Acomys dimidiatus, Thamnomys (Grammomys) dolichurus and Hystrix cristata were recorded in the riverine forests of the Jubba Valley, southern Somalia, in the dry season of 1986. Acomys dimidiatus was the most common of the five species trapped. Overall trap success was low, but increased over successive days. Saccostomus mearnsi, Praomys natalensis, Acomys dimidiatus and Thamnomys dolichurus all showed signs of breeding, and pregnant females of A. dimidiatus and T. dolichurus were trapped until the end of the dry season. Analysis of stomach contents revealed that all five trapped species relied heavily on seeds and, where comparisons could be made, the degree of overlap in diets was high. The findings are discussed in relation to the environmental conditions in the forest and neighbouring habitats.

Abstract:
We revised the taxonomic status of the putative Acomys spinosissimus complex based on the comparative study of specimen collections from Tanzania, Zambia, Zimbabwe, Mozambique, DR Congo and South Africa, by means of analysis of external morphology, craniometry, enzymes, mitochondrial DNA sequences and karyology. Our results confirm that A. spinosissimus represents a complex of species with seemingly non-overlapping distribution ranges. The distribution range of A. spinosissimus appears to be restricted between the Zambesi and Limpopo Rivers, while the reinstated A. selousi (that includes A. transvaalensis) occurs further to the South (i.e. northern limit seemingly just north of the Limpopo River). The investigated populations north of the Zambezi River are morphologically and genetically distinct from A. spinosissimus and A. selousi. Based on this evidence, we described Acomys muzei sp. nov. and Acomys ngurui sp. nov., each one occurring separately along one side of the Eastern Arc Mountains. Finally, we lacked sufficient information to describe a third new species from the area north of the Zambesi River.

Abstract:
The present paper reports sex differences in exploratory behaviour by infant Spiny Mice, Acomys cahirinus, that may, in part, be related to differences in maternal behaviour towards pups; like some other rodents, mother Acomys differentiate behaviourally between male and female pups. In Experiment 1 infant Acomys were allowed to explore a novel arena. This experiment showed that even by Day 3 (the day of birth=Day 1) female Acomys explored a novel environment more than males; they entered the arena sooner than males and spent more time in contact with a novel object. Experiment 2 showed that infant females were more active than males when observed in the home cage in the presence of their parents and made more approaches to the mother. Mothers, on the other hand, directed more licking behaviour towards males. Experiment 3 focused on the exploratory behaviour of individual pups in the presence of the mother. Given access to a large, complex arena, female pups explored more than males. The results also showed that mothers direct more of their social interactions towards sons than daughters, particularly when pups are about a week old. Some mothers appear to “direct” the movement of their offspring, by blocking their forward movement; this was done more often to male than to female pups. The data suggest that the previously observed changes in exploratory behaviour at this time, and the emergence of sex differences in exploration, may in part depend upon the mothers’ reactions to pups by sex.

Abstract:
An experiment is described in which the relative distractibility of two species of murid rodent, Acomys cahvrinus and Mus musculus, was compared. On the basis of observations derived from our previous studies of exploratory behaviour in males of these two species, we predicted that Mus would show higher levels of distractibility when presented an unexpected, novel stimulus than would Acomys. Distractibility was measured using a novel stimulus placed on the wall of a runway along which the animals had been trained to run to a food reward. The hypothesis was not supported, at least for males; indeed, male Acomys were more easily distracted from the runway task by introduction of the novel stimulus than male Mus. Among females, however, the species difference was reversed for female Mus were highly responsive to the novel stimulus. The most significant difference shown in this experiment appears, however, to be that between male and female Mus, since male Mus showed relatively little response to the stimulus change. The results are discussed in relation to possible hormone differences and differences between the species, in responses to novelty.

Abstract:
In 2000, we determined levels of damage by acorn weevils (Curculio spp.) and patterns of acorn fall in a northern red oak (Quercus rubra L.) seedling orchard in eastern Tennessee. The mean (±SE) production of acorns among 43 selected trees was 5,930 ± 586 acorns per tree with a maximum production level of 16,969 acorns for one tree. Trees were selected in the spring of 2000 based on abundance of acornets. The mean (±SE) damage level to acorns was 33 (±2) percent (determined by dissection). The floating method for assessing sound acorns overestimated acorn damage by 36 percent overall. Weevils accounted for approximately 66 percent of all damage to acorns. We found that the percentage of weeviled acorns was negatively correlated to total acorn production per tree. The rate of acorn drop was higher in October and November than in September. However, the percentage of acorns damaged by weevils was higher for acorns falling in September than for acorns falling in October or November.

Abstract:
Red oak (Quercusrubra L.) acorns were collected from three trees in September, placed in plastic bags, and held at 2 °C for 150 days. Acorns were given 0-, 10-, or 14-day aerated water soaks before germination tests were conducted. Acorns from two trees, given a 14-day soak, had significantly higher germination capacity and uniformity than untreated acorns. In another test, acorns were given a 10-day aerated water soak treatment and returned to 2 °C for 30 and 60 days. After 30 days, treated acorns had superior germination compared with untreated acorns. After 60 days, there were no significant differences in germination between treated and untreated acorns. In a greenhouse study, acorns given an aerated water soak had higher shoot-emergence capacity than untreated acorns. However, the aerated water soak treatment did not increase seedling efficiency, the ratio between the number of plantable seedlings and the number of seeds sown.

Abstract:
Predation by curculionid larvae, tannic acid content, and germination were measured in acorns from individual trees of Quercusalba and Quercusrubra from two sites at the Meeman Biological Field Station, Shelby County, Tennessee, U.S.A. A crossed and nested analysis of variance design was used, and no significant differences were found among trees or between sites in percentages of acorns that were attacked nor in tannic acid contents. Quercusrubra acorns had significantly less predation and higher amounts of tannic acid than Q. alba acorns. Acorns of both species that were not attacked had significantly higher germination success (82% for Q. alba and 98% for Q. rubra) than acorns that were attacked. There was no significant relationship between amount of predation and tannic acid content for acorns from trees of either species. Tannic acid content appears to have an impact by reducing seed predation and may interact with seed crop size to increase annual germination success of trees.

Abstract:
Twenty four Black goat does at 1st week post kidding were adapted to control diet for 2 weeks and then blocked into 4 groups (6 does/group) to be fed on one of the experimental diets (0, 5, 10 and 15% oak acorns) to study the effect of different levels of oak acorns on milk yield, milk composition and some serum biochemical traits. Results revealed that at 10th week of lactation, there was a significant increase in daily milk yield in does fed on 15% oak acorns. In contrast the group fed on 15% oak acorns exhibited a significant decrease in milk protein and solid non-fat contents at 10th week of lactation. The milk lactose yield was significantly higher in group fed on 15% oak acorns at 10th week of lactation. The serum glucose concentration at 8th week of lactation was significantly higher in does fed on 10% oak acorns while at 10th week; it was significantly higher in does fed 5% oak acorns. It could be concluded that feeding does on diets containing 15% oak acorns caused a significant increase in daily milk yield of Black goats and a significant decrease in milk protein content.

Abstract:
Abstract The objective of this study was to examine the relation of dormancy break requirements to winter submergence effects on germination and viability in cherrybark, willow, and Nuttall oak acorns. Acorns were submerged in a greentree reservoir and received 0, 21, 42, 63, or 84 days of winter submergence, followed by 8 weeks of incubation in four temperature regimes (15/6°, 20/10°, 25/15°, and 30/20° C). Winter submergence substituted for cold stratification requirements of cherrybark oak acorns, and dormancy break was achieved with 63 days of submergence. Although winter submergence exerted a positive effect on germination in Nuttall and willow oak acorns, dormancy break was not achieved in acorns of either species. Germination percentages were highest in the 30/20° C incubation temperature—cherrybark oak acorns (75–83 percent), followed by Nuttall oak (33–55 percent) and willow oak (14–52 percent). Among treatment combinations, all willow oak nongerminants were viable. Viability loss in cherrybark and Nuttall oak acorns was greatest in the 63- and 84-day treatments. The dynamics of acorn germination in response to winter hydrologic regime is influenced by submergence duration that may, or may not, satisfy dormancy break requirements in acorns of these red oak species.

Abstract:
Partially stratified (11 days) southern red oak (Quercus falcata Michx.) acorns were placed at three depths in a reconstructed forest floor and subjected to simulated prescribed winter burns. Within the forest floor, acorns were placed within the L layer, at the upper-F/lower-F interface, and at the lower-F/mineral-soil interface. Winds for a backfire and headfire were generated by electric box-fans. After the burns, acorns were transferred to moist sand flats, stratified for an additional 16 days, then assessed for viability during a 45-day germination test. As depth within the forest floor increased, germinative capacity of acorns increased. All acorns placed within the L layer during prescribed burning failed to germinate. Germinative capacity of acorns placed at the upper-F/lower-F interface was lower (P=0.03) in the backfire (8.75%) than in the headfire (55.00%). At the lower-F/mineral-soil interface, there was no difference (P=0.09) in germinative capacity between backfire (92%) and headfire (89%), and their mean was no different (P=0.26) than the 93% achieved by unburned control acorns.

Abstract:
The aim of this study was to assess the effects on root deformations in Mediterranean cork oaks Quercus suber L. of container size and radicle length at the time of sowing. Acorns at five sowing methods – intact acorns, acorns that had germinated during storage, acorns that had germinated after moist stratification and acorns with radicles (R) less than 5 mm in length, 7 mm to 12 mm in length and more than 15 mm length – were planted individually in WM type containers of 400 cm3, 800 cm3 and 1,200 cm3. At the end of the nursery growth period, the roots of the 1,080 sampled seedlings were examined for root deformities. The experiment results showed that root deformation affected almost half (49%) of the container-grown cork oak seedlings and that the germination status of acorns at the time of planting had a significant effect on root deformations, whereas container volume had no clear effect. The largest number of deformed roots (91%) was observed in seedlings grown from germinated acorns, as compared to 9% of seedlings grown from intact acorns. Planting germinated acorns with radicles 15 < R < 20 mm and 7 < R < 12 mm in length produced the highest percentages of detrimental deformations. Irrespective of size, the bottomless WM container type was shown to be highly effective against the root spiralling frequently observed in closed cylindrical polyethylene bags. The results of this study could help to improve cork oak seedling quality for more successful reforestation programs.

Abstract:
Introduction: In Mexico, there is a lack of information on morphological, physical and chemical characteristics of acorns of Quercus, which makes it difficult to make decisions on the use that can be made to the fruits. Objectives: To identify the morphological, physical and chemical characteristics of Quercus rugosaNée, Q. sideroxyla Humb. & Bonpl. and Q. deserticola Trel. acorns. Materials and methods: From each species, 10 trees were selected and 30 acorns per tree were collected. Mature acorns were characterized morphologically (polar and equatorial diameter, shell weight and total weight) and in physicochemical characterization (moisture, dry matter, ash, crude fiber and protein, ethereal extract and tannins) green and mature acorns were used. Differences among species and among maturity stages were determined with an analysis of variance (P ≤ 0.05) and subsequent Tukey’s test. Results and discussion: Morphology varied among species and among trees of the same species (P < 0.05); Q. deserticola had the largest acorn size (15.69 mm) and weight (1.94 g), and Q. sideroxylaproduced the smallest acorns. Maturity stage and species significantly (P < 0.05) influenced chemical composition; mature acorns had higher content of ethereal extract (8.88 %) and protein (8.40 %). Pearson’s correlation indicated that acorn weight was strongly associated with crown diameter and diameter at breast height. Conclusion: Significant differences were found in morphology and chemical composition of acorns of each species, although they inhabit sites with similar characteristics.

Abstract:
Few studies have determined the influence of acorn size on germination and predation percentage at tree level. To evaluate the seed size influence at individual tree level, trees producing two different sizes of acorn were chosen. Our results show that smaller acorns were significantly more infested (49.6–75.3%) than larger ones (11.0–27.33%). About germination, big acorns achieved the best germination percentage compared to the smaller ones (18% in infested and 76% in sound acorns for the small acorn group versus 69.3% in infested and 93.3% in sound acorns belonging to the big acorn group). We also found that there was a difference in behaviour between big and small seeds at tree level. The same size belonging to different functional groups presented a difference at the behavioural level per tree. Infested small acorns from trees 8 and 10 had only 33 and 13% germination, while big acorns from trees 2, 3, and 6 (there was no difference between both sizes) presented 67, 97, and 83%, respectively. These results indicate that the production of acorns with two different sizes could be a strategy for species regeneration, producing each size for a different purpose.

Abstract The aim of the study was to demonstrate the degree of healthiness of the pedunculate oak (Quercus robur) acorns found in the Włoszczowa-Jędrzejów Nature Park (abbreviation: W-JOChK) and in the neighbouring area. It was dealt with by making the analysis of health of the acorns (total 3,600). The research material included the samples of fallen down acorns, collected under the pedunculate oaks in Kurzelów (W-JOChK), as well as Żelisławice. The study was conducted from late September 2014 to early October 2015. The analysis of acorns demonstrated that over 50% of the acorns were damaged by insects. The ‘perpetrators’ of the damage proved to be Curculio glandium (Coleoptera: Curculionidae - acorn weevil) and Cydia splendana (Lepidoptera: Tortricidae - chestnut tortrix). It was stated that acorns from the pedunculate oak trees, which were found on the protected area, were twice less frequently inhabited by Curculio glandium than those originating from the trees in Żelisławice - near the industrial firm. The damages caused by Cydia splendana in both study sites were similar in number. The results indicate that the acorns of oaks in more polluted environment are probably more vulnerable to infestation by insects.

Abstract:
Desiccation of northern red oak (Quercus rubra L.) acorns can impact seed viability. We examined use of X-ray image analysis of cotyledon damage in dried acorns to predict germination capacity and seedling vigor. Acorns collected from five half-sib sources were X-rayed before and after drying to one of four moisture content (MC) levels (30%, 25%, 20%, or 15%) or maintained as nondesiccated controls (35%–38% MC). X-ray images were scored qualitatively according to degree of cotyledon–cotyledon and cotyledon-pericarp separation. Following sowing, acorns were evaluated for number of days to reach each of three developmental stages (emergence of radicle, epicotyl, and first leaf flush) and growth for 80 d. Both MC and family significantly affected all variables. The percentage of acorns to reach each developmental stage, as well as final height and root-collar diameter declined with decreasing MC and dropped most notably between 20% and 15% MC. X-ray separation scores more effectively predicted the percentage of acorns to reach each of the first three developmental stages than MC level (R2 = 0.49–0.63 vs. 0.40–0.59). Our results confirm the recalcitrant nature of northern red oak acorns and demonstrate the potential of X-ray image analysis to provide a rapid and nondestructive means to successful predict acorn viability.

Abstract:
Abstract. The impact of altitudinal zone on the nutritional quality of kermes oak (Quercus coccifera L.) acorns was assessed in Xirovouni Mountain shrublands in northwestern Greece. Whole acorns were collected during autumn 2011 from 15 sites located at three altitudinal zones (i.e. lower, middle, upper). Kermes oak acorn samples were manually separated into kernel and hull and analysed for chemical composition (crude protein, CP; neutral detergent fibre, NDF; acid detergent fibre, ADF; lignin), in vitro dry matter (DM) digestibility (IVDMD), in vitro NDF digestibility (IVNDFD), digestible energy (DE), and minerals (i.e. Ca, P, K, Mg, Mn, Fe, Zn, Cu). Altitude had a negative correlation with CP, IVDMD, and IVNDFD and positively correlated to cell wall contents in both kernel and hull. Acorns growing under higher temperatures (at lower altitude) have more digestible cell wall compared to acorns growing under lower temperatures (at higher altitude) due to increased CP content and decreased cell wall content. It seems that environmental factors affect the nutritional value of acorns. Thus, goat farmers should take this into account when collecting acorns to feed their animals.

Abstract:
AbstractSeed hoarding by granivorous animals requires cache-protection strategies which allow to protect hoarded seeds against pilferage. This study reports the first case of acorn hoarding in tree cavities by Eurasian Jays (Garrulus glandarius). Out of 116 removed acorns of both pedunculate oak (Quercus robur) and Northern red oak (Q. rubra), we localized 14 consumed and 102 stored acorns. Five experimental acorns (4.9% of stored acorns) were found stored in tree cavities. The notion that hoarding seeds in tree cavities may constitute a cache-protection behavior of Eurasian Jays represents a working hypothesis that ought to be tested in future studies.

Abstract:
In this study, the impact of wild boar on the natural regeneration of oak and importance of acorns in the wild boar diet were surveyed. The data were collected near Moravian Krumlov (Czech Republic) in three types of oak stands differing in the canopy density: fully-stocked stand (1), open-canopy stand (2) and the forest stand in a conversion to the coppice forest (3). Within each stand 150 m long lines were set out. Seed traps to collect acorn harvest and control plots were installed on these lines. The plots were inspected at weekly intervals. After the end of acorn fall the average amount of fallen acorns was evaluated. The quantity of metabolizable energy in acorns was assessed and daily survival dose of energy for average weight of wild boar was counted. In spring 2014 the number of seedlings was counted at the same plots. Production of acorns per hectare and basic energy needs for one individual wild boar per day were evaluated for each chosen stand type. The found seedling density amounted to 29,600, 32,000 and 14,000 ind./ha in the first, second and third stand under study, respectively. Wild boar is a major consumer of acorns. In the studied area the production of acorns sufficiently supplied the local wild boar population during winter. Necessary amount of acorns remained for the natural regeneration.

Abstract:
This study aimed to examine the response of sheep and goats to dietary effects of feeding different levels of oak (Quercus aegilops) acorns in terms of nutrient digestibility, nitrogen balance, rumen function and some serum metabolites. The study was conducted over 4 periods each of 15 days; in each period, rams and bucks were allocated to one of the dietary treatments (control, 5, 10 and 15% oak acorns). Rams and bucks exhibited different responses to the effects of dietary levels of oak acorns. The digestibility coefficient of DM was reduced in both rams and bucks upon feeding acorns, but this decline was significant (P≤0.05) only in rams fed 10 and 15% acorns as compared to rams fed control. Also, the rams and bucks showed numerical decrease in digestibility coefficients of OM, CP, CF, and NPN. The experimental treatments had no effects on nitrogen balance parameters. Bucks exhibited significantly (P≤0.05) higher concentrations of rumen ammonia-nitrogen before, 4 hours and 6 hours after morning feeding. The rumen pH value was significantly (P≤0.05) by the animal species only at the time before morning feeding. The serum metabolites were not affected by the level of acorns in the diet. The results of this study indicate that goats are superior in digesting diets containing oak acorns up to 15%.

Abstract:
Three separate collections of Ontario sources of northern red oak (Quercus rubra L.) acorns were made to determine the effects of long-term cold storage at +2°C, −1°C, and −2°C on their viability and vigour. We measured acorn moisture content, percent germination during storage, speed of germination and total germination values, root regrowth of seeds that germinated in storage, incidence of fungal contamination, and condition of ungerminated acorns. Viability and vigour peaked six to 12 months after acorns were placed in storage, but decreased with continued storage. After 18 months in storage, ≥60% of the acorns germinated in four of the five seedlots tested and, after 30 months in storage, ≥53% of the acorns germinated in three of the five seedlots tested. Acorn viability was only minimally affected by storage temperature; however, since temperatures above −2°C allowed acorns to germinate during storage, the preferred long-term storage temperature was −2°C. Our results suggest that, assuming proper storage conditions, most red oak seedlots will maintain relatively high germination levels when stored at −2°C for 18 months. Seedlots with particularly high initial germination and vigour may be successfully stored for up to 30 months.

Abstract:
Acorns produced by oak (genus Quercus L.) trees are eaten by numerous wildlife species, many of which may also contribute to oak regeneration by dispersing acorns to favorable microhabitats. According to the directed dispersal hypothesis, seed dispersal agents may preferentially move seeds to locations that favor seedling establishment. As a case study of the directed dispersal hypothesis, we tested the hypothesis that vertebrate scatterhoarders preferentially cache acorns in locations where conditions favor germination. We planted acorns within 0.3 m of known cache sites (cache plots) and at paired random plots that were located at equal distances from the acorn source. We then monitored germination, seedling emergence, and growth over the first year. Acorns near actual cache sites germinated at lower rates than acorns in random sites, the opposite of what would be predicted by the directed dispersal hypothesis, but insufficient seedling survival prevented statistical analysis of survival and growth. These results do not support the directed dispersal hypothesis with regard to the microhabitat at cache plots, and do not address the effects of seed burial or the potential for longer term positive effects on survival of germinated seedlings.

Abstract:
Abstract Red oak Quercus spp., Subgenus Erythrobalanus acorns are forage for mallards Anas platyrhyncos, wood ducks Aix sponsa, and other wildlife that use bottomland hardwood forests in the southeastern United States. However, annual variation in true metabolizable energy from acorns would affect carrying-capacity estimates of bottomland hardwood forests for wintering ducks. Because gross energy and true metabolizable energy are strongly positively correlated and gross energy is easier to measure than true metabolizable energy, we used gross energy as a surrogate for true metabolizable energy. We measured gross energy of six species of red oak acorns in autumns 2008 and 2009. Within species, mean gross energy of these acorns varied less than 2% between years. The small interannual variation in gross energy of red oak acorns found in this study would have negligible effect on estimates of carrying capacity of bottomland hardwood forests for wintering ducks and other wildlife.

Viability of bur oak Quercus macrocarpa Michx. acorns was determined after 6 months storage at − 2°C (28°F), 1°C (34°F) and 5°C (41°F) and moisture contents of either 17%, 27%, 37% or 44%. Viability was significantly affected by moisture content with optimum germination occurring for acorns stored at 44% moisture. Optimum storage temperature was 1°C (34°F) although acorns tolerated subfreezing temperatures to − 2°C (28°F) with little loss in viability. Acorn moisture content had a greater effect on viability than storage temperature. Storage for up to 6 months had no detrimental effects on germination of bur oak acorns.
