Fig 6 The minimum age of each embryo from day of oviposition (maximum age indicated by error bar). Embryos that were between two stages (e.g., Stage 6 to 7) were given a value half-way between the two stages (e.g., 6.5). Closed circles: embryos incubated at a daily 12:12 h cycle of 30:15°C; open circles: embryos incubated at 30:15°C for the initial 35 days and then the daily maximum and minimum temperatures were varied each week thereafter. Inset: embryos in various stages of development in week 8.

Figure 5 - Flexible syntax, prepositions, adjectives, verb tenses, and other common elements of grammar, all facilitate the human ability to communicate an infinite number of novel images with the use of a finite number of words. The graph shows the number of distinct images that can be transmitted with high fidelity in a communication system with 1,000 nouns as a function of the number of spatial prepositions. In a communication system with no spatial prepositions and other recursive elements, 1000 nouns can communicate 1000 images to a listener. Adding just one spatial preposition allows for the formation of three-word phrases (such as: 'a bowl behind a cup' or 'a cup behind a bowl') and increases the number of distinct images that can be communicated to a listener from 1000 to one million (1000x1x1000). Adding a second spatial preposition and allowing for five-word sentences of the form object-preposition-object-preposition-object (such as: a bowl on a cup behind a plate) increases the number of distinct images that can be communicated to four billion (1000x2x1000x2x1000). The addition of a third spatial preposition increases the number of distinct images to 27 trillion (1000x3x1000x3x1000x3x1000), and so on. In general, the number of distinct images communicated by three-word sentences of the structure object-preposition-object equals the number of object-words times the number of prepositions times the number of object-words. A typical language with 1000 nouns and 100 spatial prepositions can theoretically communicate 1000101 x 100100 distinct images. This number is significantly greater than the total number of atoms in the universe. For all practical purposes, an infinite number of distinct images can be communicated by a syntactic communication system with just 1000 words and a few prepositions. Prepositions, adjectives, and verb tenses dramatically facilitate the capacity of a syntactic communication system with a finite number of words to communicate an infinite number of distinct images. Linguists refer to this property of human languages as recursion. The "infiniteness" of human language has been explicitly recognized by "Galileo, Descartes, and the 17th-century 'philosophical grammarians' and their successors, notably von Humboldt" (Hauser et al. 2002). The infiniteness of all human languages stand in stark contrast to finite homesign communication systems that are lacking spatial prepositions, syntax, and other recursive elements of a formal sign language.

Figure 4 - Synchronicity has to be understood in terms of synchronicity of the arrival of action potentials to a target neuron rather than absolute equality of action potential conduction times over different paths. Consider the following example: suppose neuron A is receiving excitatory input from neurons B and C via two different pathways (neuron A is the target neuron for both neurons B and C). Suppose that the action potential conduction time is 2ms from neuron B to neuron A and 22ms from neuron C to neuron A (i.e., the axonal pathway B-A has a significantly shorter conduction time than the axonal pathway C-A). Does it mean that the connections B-A and C-A are always asynchronous? No. The answer depends on the predominant neural activity rhythm in this network. At the firing rate of 50Hz (inter-spike interval of 20ms that correspond to Gamma rhythm), neurons B and C can actually be considered synchronous in relationship to neuron A: consider a train of action potentials synchronously fired by neurons B and C. The first action potential from neuron B will reach neuron A in 2ms and the first action potential from neuron C will reach neuron A in 22ms. Obviously, there would be no coincidence in the arrival times of the 1st action potentials from neurons B and C. However the second action potential from neuron B will arrive to neuron A in 22ms, concurrently with the 1st action potential from neuron C. Thus, starting with the second action potential, neuron A will receive synchronous activation from neurons B and C. The synchronous activation has a significantly greater probability of enhancing synaptic connections between neurons A and B, and A and C (Hebbian learning: 'neurons that fire together, wire together' (Hebb 1949). Thus, synchronicity does not need to imply absolute equality in the conduction time over different pathways. Rather synchronicity implies near-zero phase-shift between the two firing trains of action potentials at the postsynaptic cells. This phase-shift depends on conduction times over each pathway and also on the dominant firing frequency in the neural network.

Figure 2 - A typical question testing subject's ability to mentally rotate an object is shown here as a 2x2 matrix with six answer choices displayed below the problem. The top row of the matrix indicates the rule: "the object in the right column is the result of 45° clockwise rotation." Applying this rule to the bottom row, we arrive at the correct answer depicted on the right.

Figure 6 - The German HNV monitoring methodology and results - HNV value decline In Germany, the HNV monitoring methodology has enabled an initial assessment of the trend in HNV value of farmland. Between 2009 and 2013, there was a significant decline of HNV value, in particular in the HNV class III, which represents the lowest value (in terms of species richness and structure). Graph reproduced from (Benzler et al. 2015).

Figure 1 - Visual information processing in the cortex. From the primary visual cortex (V1, shown in yellow), the visual information is passed in two streams. The neurons along the ventral stream also known as the ventral visual cortex (shown in purple) are primarily concerned with what the object is. The ventral visual stream runs into the inferior temporal lobe. The neurons along the dorsal stream also known the dorsal visual cortex (shown in green) are primarily concerned with where the object is. The dorsal visual stream runs into the parietal lobe.

Figure 5 - Opinions of RDP policy evaluators on data availability and bottlenecks. Results reproduced from ENRD 2012. A group of 58 RDP policy evaluators were asked about data availability and bottlenecks to data use for agricultural policy impact evaluation in 2007-2013. In response to the question: "To what extent are sound data available to carry out RDP impact evaluations?" 2% (1) replied 'fully available', 24% (14) replied 'largely available', 72% (42) replied 'partly available', 2% (1) replied 'not available'. The answers to the question "What are the major bottlenecks in providing sound data for the assessment of RDP impact in 2007-2013?" are shown in the graph.
