The definitive version was published in Ecological Applications 15 (2005): 1462–1470, doi:10.1890/03-5354.Leaf area index (LAI) is a powerful diagnostic of plant productivity. Despite the fact that many methods have been developed to quantify LAI, both directly and indirectly, leaf area index remains difficult to quantify accurately, owing to large spatial and temporal variability. The gap-fraction technique is widely used to estimate the LAI indirectly. However, for low-stature vegetation, the gap-fraction sensor either cannot get totally underneath the plant canopy, thereby missing part of the leaf area present, or is too close to the individual leaves of the canopy, which leads to a large distortion of the LAI estimate. We set out to develop a methodology for easy and accurate nondestructive assessment of the variability of LAI in low-stature vegetation. We developed and tested the methodology in an arctic landscape close to Abisko, Sweden.
The LAI of arctic vegetation could be estimated accurately and rapidly by combining field measurements of canopy reflectance (NDVI) and light penetration through the canopy (gap-fraction analysis using a LI-COR LAI-2000). By combining the two methodologies, the limitations of each could be circumvented, and a significantly increased accuracy of the LAI estimates was obtained. The combination of an NDVI sensor for sparser vegetation and a LAI-2000 for denser vegetation could explain 81% of the variance of LAI measured by destructive harvest. We used the method to quantify the spatial variability and the associated uncertainty of leaf area index in a small catchment area.This research was funded by U.S. National Science Foundation

Morphological modelling of Lai Giang Inlet, Vietnam.
No full textThe Lai Giang inlet located in Binh Dinh province incorporates various features of the estuaries in the Central part of Vietnam. Belonging to the micro-tidal and wave-dominant coast and influenced by the monsoon regime, the inlet has a seasonal character. During the dry season, as the river flow diminishes, the wave action causes high level of sedimentation and closes up the inlet eventually. In flood season, as the river discharge is high, the channel is scoured and the inlet begins to migrate. The high sedimentation level and migration of the Lai Giang inlet has been a serious problem of Binh Dinh province for a long time, because it is the only exit for the floodway. It is an anchorage and also the connection between the sea and the aquaculture area of Hoai Nhon district. The high level of sedimentation at the entrance of the inlet prevents river flood from flowing smoothly, thus leading to overflow in lowlands and navigation issues. In recent decades, the exploitation and protection of Lai Giang area have been studied in various forms of scientific researches and projects by different scientists and local professional agencies. However, the studies have only focused on hydraulics, hydrology and on adjusting the flow of Lai Giang river. There are only general and basic studies on the entrance of the inlet. The main objective of this research is to understand the morphological behaviour of Lai Giang inlet. The specific interest is focused on the main factors which are the tidal characteristic, the wave climate and the river flow during the flood season, and the interaction between all these factors that influence the morphological changes. The study starts with the collecting and analysing all the documentations to come up with a conceptual model of the Lai Giang inlet to explain how the sedimentation and the migration processes happen. Then, the Delft3D modelling software, which can model (tidal) flow, waves and sediment transport, has been applied to confirm the hypothesis and gain further knowledge. According to the data analysis, the conceptual model as well as the descriptive and quantitative result of the model, we can make the following main conclusions: 1. The wave climate in this area has seasonal characteristic and is dominated by two main directions; Northeast and Southeast in winter and summer monsoon, respectively. 2. During the summer monsoon, the longshore sediment transport moves towards the north, bypasses the entrance of the inlet and gradually builds up on the down-drift spit due to the Southeast Wave. 3. During winter monsoon, the Northeast wave intensifies the southward longshore sediment transport leading to the large amount of sedimentation in front of the inlet. At the same time, the significant river flow flushes away the sediment deposits at the main ebb channel located nearer to the up-drift spit. Thus the sedimentation could not take place at the up-drift spit. The sediment displacement at the up-drift and down-drift spit made the inlet migrate to the north gradually. Finally, the possibility to stabilize the inlet is discussed to give the optimum solution for this area.CoMEM - Coastal and Marine Engineering and ManagementHydraulic EngineeringCivil Engineering and Geoscience

Sensory papillae not distinguishable from other papillae. Dorsum of posterior sucker with few scattered papillae. Venter smooth.</p> <p> <b>Gonopores:</b> Separated by one annulus; male at XII a1/a2 (26th/27th annulus); female at XII a2/a3 (27th/28 th annulus); both strictly within furrows.</p> <p> <b>Digestive system:</b> Proboscis cylindrical, slender, slightly tapered terminally; in flattened specimens about equal in length to total of 10 annuli. Salivary glands diffuse; gland cells loosely distributed beside the pharynx in XI–XIV. Crop in XIV–XIX; 6 pairs of caeca; first 5 pairs in XIV–XVIII simple, unlobed and unbranched, directed laterally and confined to their respective segments as the first two pairs often indistinct and vague when empty; sixth pair in XIX elongate, deflected posteriorly and lateral to intestine, extended to about XXII obliquely. Four pairs of unlobed intestinal caeca in XX–XXIII. Hind gut saccate, rectum narrow and oblique, tapering towards anus.</p> <p> <b>Male Reproduction System:</b> Four pairs of testisacs intersegmentally arranged at XV/XVI–XVIII/XIX. Vas deferens enters sperm duct in XIII, expands into seminal vesicle with S-shaped loop. Ejaculatory duct almost straight, with the same wide and proceeds obliquely outward and forward up to XI.

However, it can be distinguished from <i>H. stagnalis</i> and other scutiferous species of the genus by the first two pairs of crop caeca being unapparent, and by having only four pairs of testisacs; fewer than six pairs of testisacs in the <i>Helobdella</i> species is unusual.</p> <p> Since <i>H. octatestisaca</i> has a conspicuous scute on the neck region of the middorsum, it is less likely that the species had been incorrectly identified as a nonscutiferous species by former researchers in Taiwan. In addition, the morphological similarity between <i>H. octatestisaca</i> and the well known widespread leech <i>H. stagnalis,</i> recorded for decades in China, India, and Japan, also reduced the possibility of misidentification (Harding & Moore 1985; Uchida 1965; Yang 1996). In our survey, <i>H. octatestisaca</i> was found commonly in easily accessible habitats, such as rice paddies and irrigation ditches where they should have been discovered by past researchers. However, <i>H. octatestisaca</i> or any scutiferous leeches have never been discovered or mentioned in any hirudinea fauna survey in Taiwan (Oka 1910, 1923, 1925, 1928 a– c, 1929 a – c, 1930, 1931, 1934; Takahashi 1931, 1933, 1934 a – b, 1935). Hence, it was inferred that <i>H. octatestisaca</i> is probably a recently invaded species in Taiwan.</p>Published as part of <i>Lai, Yi-Te, Chang, Chih-Han & Chen, Jiun-Hong, 2009, Two new species of Helobdella Blanchard 1896 (Hirudinida: Rhynchobdellida: Glossiphoniidae) from Taiwan, with a checklist of hirudinea fauna of the island, pp. 27-46 in Zootaxa 2068</i> on pages 30-34, DOI: <a href="http://zenodo.org/record/187040">10.5281/zenodo.187040</a>

Optimal Exploitation of the Sentinel-2 Spectral Capabilities for Crop Leaf Area Index Mapping
No full textThe continuously increasing demand of accurate quantitative high quality information on land surface properties will be faced by a new generation of environmental Earth observation (EO) missions. One current example, associated with a high potential to contribute to those demands, is the multi-spectral ESA Sentinel-2 (S2) system. The present study focuses on the evaluation of spectral information content needed for crop leaf area index (LAI) mapping in view of the future sensors. Data from a field campaign were used to determine the optimal spectral sampling from available S2 bands applying inversion of a radiative transfer model (PROSAIL) with look-up table (LUT) and artificial neural network (ANN) approaches. Overall LAI estimation performance of the proposed LUT approach (LUTN₅₀) was comparable in terms of retrieval performances with a tested and approved ANN method. Employing seven- and eight-band combinations, the LUTN₅₀ approach obtained LAI RMSE of 0.53 and normalized LAI RMSE of 0.12, which was comparable to the results of the ANN. However, the LUTN50 method showed a higher robustness and insensitivity to different band settings. Most frequently selected wavebands were located in near infrared and red edge spectral regions. In conclusion, our results emphasize the potential benefits of the Sentinel-2 mission for agricultural applications
The field measurements and high resolution reference LAI data in Hailun and Honghe, China
No full textThe file includes both field measured and satellite derived high resolution LAI data obtained over the Honghe farm and Hailun site in northeastern China.
The Honghe farm (centered at 47°39′N, 133°31′E) is located in the east of the Heilongjiang province, northeast China. Five plots in 400 m × 600 m were selected in the Honghe farm in 2012 and 2013. Within each plot, about 50 - 60 elementary sampling units (ESUs) about 20 m ×20 m in size were selected in different weeks with a moving sampling strategy to avoid the sampling disturbance. Field LAI measurements were performed weekly from June 11 to September 17, 2012, and from June 22 to August 27, 2013. All ESU measurements made with LAI-2200 within a plot were averaged to represent the plot LAI.
The Hailun site (47°24′- 47°26′N, 126°47′- 126°51′E) is located in the western part of the Heilongjiang province. The main crop types are maize, soybean, and sorghum. Five crop plots in 100 m × 500 m were chosen for continuous LAI measurements. The plots cover an areas of about 30 km2 and an elevation of approximately 200-240 m above sea level with quite homogeneous surroundings. Three representative ESUs of approximately 20 m × 20 m were selected in each plot. Field LAI measurements were continuously carried out with LAI-2200 weekly at each plot from June 20 to September 22, 2016.
The high-resolution LAI data were estimated with a look-up table (LUT) method from the HJ-1, Landsat 7 ETM+, and Sentinel-2A MSI reflectance data. The high resolution LAI data are consistent with the field measured LAI characterized by a slope close to the 1:1 line. The statistical results show R2 of 0.81 and 0.86, and RMSE of 0.62 and 0.70 for paddy rice and broadleaf crops, respectively. The scale factor is 0.01

Underneath stone in Guandu Plain, Taipei, Taiwan, collected by Yi-Te Lai, 01 October 2006.</p> <p> <b>Etymology:</b> The specific name is alluding to the conspicuous black pigmentation around the anus and the gradual increase of black pigmentation on the annuli and papillae of the posterior body.</p> <p> <b>Diagnosis:</b> The body length is less than 10 mm. No scute. On the pale dorsum, the papillae are more and more apparent and pigmented on the posterior annuli. The anus is significantly pigmented. Hence this species can be easily distinguished by the obviously pigmented anus as well as the increasing pigmentation and protrusion of dorsal papillae. Internally, five pairs of crop caeca and four pairs of testisacs are significant characters to be recognized.</p> <p> <b>Form:</b> Body length 4.0–5.5 mm, maximum body width 2.0–2.3 mm, anterior sucker diameter 0.3–0.4 mm, posterior sucker diameter 0.9–1.0 mm.

Cephalic sucker cupuliform with thickened rim; proboscis pore small, in centre of cavity. Posterior sucker circular, diameter almost equal to half to one third of maximum body width, with thick margin and flat venter, broadly attached, directed ventrally or slightly caudalventrally. No nuchal scute present.</p> <p> <b>Color and pattern:</b> When alive, body translucent, color of gray, green, pink, or unpigmented. Dorsum with tiny black or olive dots arranged transversely in every annulus but indistinct in those of one third of anterior body. Pale brown or green chromatophores arranged through the body surface, accumulated more in more posterior annuli. Venter without any chromatophores, with tiny black dots arranged transversely and marginally. Dorsum of posterior sucker with irregularly distributed black spots. Venter without any dots or spots.</p> <p> <b>Eyes:</b> One pair, punctiform to triangular in median field in III (3rd annulus).</p> <p> <b>Annulation:</b> 67 annuli in holotype specimen.

The middle row of papillae distinguishable and black-tipped from XVII–XXVII; while the submarginal rows of papillae from XXIII–XXVI. Dorsum of posterior sucker with no distinct papillae. Venter smooth.</p> <p> <b>Gonopores:</b> Separated by one annulus; male at XII a1/a2 (26th/27th annulus); female at XII a2/a3 (27th/28th annulus); both strictly within furrows.</p> <p> <b>Digestive system:</b> Proboscis cylindrical and robust; in flattened specimens, no more in length than 10 annuli. Salivary glands diffuse; gland cells loosely distributed beside the pharynx in XI–XIV. Crop in XV–XIX; 5 pairs of caeca; first 4 pairs in XV–XVIII simple, unlobed and unbranched, directed laterally and confined to their respective segments as the first pair often indistinct and vague when empty; fifth pair in XIX elongate, deflected posteriorly and lateral to intestine, extended to about XXIII obliquely. Four pairs of unlobed intestinal caeca in XX–XXIII. Hind gut saccate, rectum narrow and oblique, tapering towards anus.</p> <p> <b>Male reproduction system:</b> Four pairs of testisacs, intersegmentally arranged at XV/XVI–XVIII/XIX. Vas deferens enters sperm duct in XII/XIII, expands into seminal vesicle with S-shaped loop. Ejaculatory duct straight, uniformly broad and proceeds sometimes obliquely inward and forward up to XI. Terminal end of ejaculatory duct turning smoothly inwards towards atrial cornu at XI/XII, narrows at junction with cornu at XI/XII. Cornua muscular, strongly divergent, ovate in dorsal view. Atrium short and indistinct.</p> <p> <b>Female reproduction system:</b> Ovisacs directed caudally; oviducts joined into short and indistinct atrium in XII.</p> <p> <b>Habitat:</b> Attached on the surface of submerged or semisubmerged stones, woodblocks, artificial trash, and the shell surface of apple snail <i>P. canaliculata</i> and the viviparid snail <i>Sinotaia quadrata</i> Benson in flowing water. Rarely in irrigation ditches, drainage ditches and open sewers in Taipei.</p> <p> <b>Prey or host:</b> Unknown. Tubificid worms and other aquatic oligochaetes may be the host or prey because the leeches exhibit foraging behavior while they are put into the same aquatic tank in lab. Viviparid snails may also be a prey item as <i>H. melananus</i> are usually attached on the shell surface.</p> <p> <b>Remarks:</b> Compared with other <i>Helobdella</i> species, <i>H. melananus</i> is small and thin. The unique arrangement of pigmented papillae and the significantly pigmented anus make this species different from most other known <i>Helobdella</i> species. According to our review, <i>H. conifera</i> from Yeman (Al-Safadi & El- Shimy 1993) is the only described <i>Helobdella</i> species with similar external morphology as <i>H. melananus</i>. The pattern of papillae distribution in these two species looks alike. However, the mature body size of <i>H. conifera</i> (8–15 mm in length, 2–3 mm in width) is much larger than <i>H. melananus</i> (4–5.5 mm in length, 2–2.3 mm in width). The papillae of <i>H. conifera</i> are not pigmented, while the papillae of <i>H. melananus</i> are obviously pigmented. In addition, the black-pigmented anus, which is the significant character on <i>H. melananus</i>, was not noted on <i>H. conifera</i>.</p> <p> Anatomically, <i>H.</i> melananus is different from most other <i>Helobdella</i> species by possessing five pairs of crop caeca and four pairs of testisacs, which is fewer than the number of testisacs in most of other <i>Helobdella</i> species. In addition, although the numbers of crop caeca and testisacs of <i>H. melananus</i> are the same as <i>H. conifera</i> from Yeman, these numbers do not match the original description of <i>H. conifera</i> (Al-Safadi & El- Shimy 1993). Hence, with the external and internal differences, <i>H. melananus</i> should be a new species rather than a described species.</p> <p> Since it has been demonstrated that <i>Helobdella</i> leeches have origins in the Central and South America and dispersed passively from those regions, <i>H. melananus</i> is possibly an invasive species in Taiwan with an unknown origin in the Central and South America.</p>Published as part of <i>Lai, Yi-Te, Chang, Chih-Han & Chen, Jiun-Hong, 2009, Two new species of Helobdella Blanchard 1896 (Hirudinida: Rhynchobdellida: Glossiphoniidae) from Taiwan, with a checklist of hirudinea fauna of the island, pp. 27-46 in Zootaxa 2068</i> on pages 34-37, DOI: <a href="http://zenodo.org/record/187040">10.5281/zenodo.187040</a>
