Predicting missing field boundaries to increase per-field classification accuracy
No full textWith the emergence of very high spatial resolution satellite images, the spatial resolution gap which existed between satellite images and aerial photographs has decreased. A study of the potential of these images for tree species in" monoculture stands" identification was conducted. Two Ikonos images were acquired, one in June 2000 and the other in October 2000, for an 11- by 11-km area covering the Sonian Forest in the southeastern part of the Brussels-Capital region (Belgium). The two images were orthorectified using a digital elevation model and 1256 geodetic control points. The identification of the tree species was carried out utilizing a supervised maximum-likelihood classification on a pixel-by-pixel basis. Classifications were performed on the orthorectified data, NDVI transformed data, and principal components imagery. In order to decrease the intraclass variance, a mean filter was applied to all the spectral bands and neo-channels used in the classification process. Training and validation areas were selected and digitized using detailed geographical databases of the tree species. The selection of the relevant bands and neo-channels was carried out by successive addition of information in order to improve the classification results. Seven different tree species of one to two different age classes were identified with an overall accuracy of 86 percent. The seven identified tree species or species groups are Oaks (Quercus sp.), Beech (Fagus sylvatica L.), Purple Beech (Fagus sylvatica purpurea), Douglas Fir (Pseudotsuga menziesii (Mirb.) Franco), Scots Pine (Pinus sylvestris L.), Corsican Pine (Pinus nigra Arn. subsp. laricio (Poir.) Maire var. corsican), and Larch (Larix decidua Mill.)

Teale et al., 5 th July 2004. Spirit specimen with liver and heart tissue stored at ‒80 °C at WAM. Etymology. Named in honour of Roy Teale, who has supported the work of the Western Australian Museum over many decades and collected many of the specimens used in this study. Material examined. Refer to Table 1 for a list of all P. tealei specimens examined in this study, labelled as Planigale sp. Mt Tom Price in Table 1. Diagnosis. Planigale tealei is considerably smaller in all external and cranial dimensions than each of P. kendricki, P. maculata, P. novaeguineae and P. gilesi. It further differs from each of these taxa in having a more depressed cranium and differs from P. gilesi in retaining upper and lower third premolars. It is slightly smaller than P. tenuirostris and further differs from this species in having a considerably more depressed cranium with a shorter rostrum. It is most similar in size and craniodental morphology to P. ingrami, but it differs from this taxon in having a longer snout and proportionally larger pes, and in lacking a distinct eye ring. The cranium differs from that of all named forms of P. ingrami in having a broadly rounded rather than square posterior nasal suture, a broader interorbital region, more rounded and elongate alisphenoid tympanic process that makes broad contact with the rostral tympanic process of the petrosal, a less flattened occiput and proportionally larger premolars.Published as part of Umbrello, Linette S., Cooper, Norah K., Adams, Mark, Travouillon, Kenny J., Baker, Andrew M., Westerman, Mike & Aplin, Ken P., 2023, Hiding in plain sight: two new species of diminutive marsupial (Dasyuridae: Planigale) from the Pilbara, Australia, pp. 1-46 in Zootaxa 5330 (1) on page 32, DOI: 10.11646/zootaxa.5330.1.1, http://zenodo.org/record/824888

Named in honour of Dr Peter Kendrick, in recognition of his major contribution to the understanding of the vertebrate fauna of north-western Australia. Material examined. See Table 1 for a list of all Planigale kendricki specimens examined in this study, referred to as Planigale 1 in the table. Diagnosis. Planigale kendricki (Fig. 10) is more rufous than all other members of the genus except perhaps some individuals of P. ingrami. It is substantially larger than each of P. ingrami, P. tenuirostris and P. sp. Mt Tom Price, and smaller than P. novaeguineae and P. gilesi. It is most similar in body size to some populations of P. maculata but differs from all populations of this taxon in its brighter dorsal and facial patterning. Craniodentally, it differs from all other Planigale species except P. tenuirostris in having more elongate nasals that invade deeply between the frontals. It further differs from typical P. maculata, and P. novaeguineae in having a more depressed cranium, a longer and narrower snout, and larger entoconids on M 1–3. It further differs from P. gilesi in having three upper premolars (reduced to two in P. gilesi). It also differs from P. tenuirostris in having less reduced M 1–4 protocones and less reduced entoconids on M 1–3 (usually absent on M 1–2 in P. tenuirostris).Published as part of Umbrello, Linette S., Cooper, Norah K., Adams, Mark, Travouillon, Kenny J., Baker, Andrew M., Westerman, Mike & Aplin, Ken P., 2023, Hiding in plain sight: two new species of diminutive marsupial (Dasyuridae: Planigale) from the Pilbara, Australia, pp. 1-46 in Zootaxa 5330 (1) on pages 24-25, DOI: 10.11646/zootaxa.5330.1.1, http://zenodo.org/record/824888
Phylogenetic relationships of the cuscuses (Diprotodontia: Phalangeridae) of island Southeast Asia and Melanesia based on the mitochondrial ND2 gene
No full textThe species-level systematics of the marsupial family Phalangeridae, particularly Phalanger, are poorly understood, due partly to the family’s wide distribution across Australia, New Guinea, eastern Indonesia, and surrounding islands. In order to refine the species-level systematics of Phalangeridae, and improve our understanding of their evolution, we generated 36 mitochondrial ND2 DNA sequences from multiple species and sample localities. We combined our new data with available sequences and produced the most comprehensive molecular phylogeny for Phalangeridae to date. Our analyses (1) strongly support the monophyly of the three phalangerid subfamilies (Trichosurinae, Ailuropinae, Phalangerinae); (2) reveal the need to re-examine all specimens currently identified as ‘Phalanger orientalis’; and (3) suggest the elevation of the Solomon Island P. orientalis subspecies to species level (P. breviceps Thomas, 1888). In addition, samples of P. orientalis from Timor formed a clade, consistent with an introduction by humans from a single source population. However, further research on east Indonesian P. orientalis populations will be required to test this hypothesis, resolve inconsistencies in divergence time estimates, and locate the source population and taxonomic status of the Timor P. orientalis.Shimona Kealy, Stephen C.
