There are concerns that anthropogenic harvesting may cause phenotypic adaptive changes in exploited wild populations, in particular maturation at a smaller size and younger age. In this paper, we study the evolutionarily stable size at maturation of prey subjected to size-selective harvesting in a simple predator-prey model, taking into account three recognized life-history costs of early matur...

In the production of tomatoes in greenhouses, a more or less constant number of tomatoes are ready for picking at each harvest time. In the production of bell peppers, however, large fluctuations exist in number of fruits ready to pick. This major problem in bell pepper production is called ‘flushing’: weeks with high yields are alternated by weeks with low yield. This irregular harvest pattern...

Study the effect of fruit cultivar (intact, early split, irregular crack) on (Akbari, Abbasali, Khanjari) cultivars in Damghan city to Aspergillus Flavus fungus and effect of harvest time in early split pistachio in 1389, sampling from orchards has been performed. Samples after grinding by dilute cultivating in a specific AFPA medium bottles in a completely randomized model were three times rec...

A total of 34 species belonging to 21 genera of fungi were recorded on passion fruits of both pure and hybrid origin in Uganda, however, the pure type exhibited wider spectrum (28 species and 16 genera) than the hybrid type (21 & 15). Also, yeasts (unidentified and Rhodotorula mucilaginosa) were also encountered in high numbers. Moreover, the mean count of all mycobiota obtained from the pure t...

to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...

Recent years have witnessed significant advancement in computer vision research based on deep learning. Success of these tasks largely depends on the availability of a large amount of training samples. Labeling the training samples is an expensive process. In this paper, we present a simulated deep convolutional neural network for yield estimation. Knowing the exact number of fruits, flowers, a...

This study examined how forest edges, fruit display size, and fruit colour influenced rates of seed dispersal in an endemic, bird-dispersed, New Zealand mistletoe species, Alepis flavida. To examine rates of seed dispersal, fruit removal rates were compared between plants growing on forest edges and in forest interior, and also between two morphs of plants with different coloured fruits. Two as...
