Nichols, Srinivas Vaidyanathan, Beth Gardner, Jagdish Krishnaswamy.Springer Nature eBook.Summary: Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.

Conservation of tropical forest ungulates: the way forward. - ArticleBramis JP, Messer J, Nacchiero M, Dreiling DA.Am J Gastroenterol. 1978 May;69(5):565-71.Immunoglobulins A, M and G in the pancreato-duodenal fluid (PDF) of 35 pancreatic disease-free individuals and 48 patients with chronic pancreatitis (25), hypersecretory disorders (10), renal transplanted (4) and with pancreatic cancer (9), were determined by a single radial immunodiffusion method. Although a trend of immunoglobulin hypersecretion in benign diseases and hyposecretion in malignancies was present, individual levels of Ig-A and Ig-M differed statistically only between cancer and other groups. Calculating the ratios of Ig-A to Ig-M (A/M) and Ig-A to total immunoglobulin contents (A/T) in the PDF of patients with chronic pancreatitis or cancer, however, a significantly higher or lower ratio, respectively, was found compared to control group. Differences in A/M ratios could not be detected between patients with benign diseases, but were constantly present when these patients were compared to pancreatic cancer. The underlying mechanism(s) of the disturbed immunosecretory system in pancreatic diseases remains speculative. Nevertheless, immunoglobulin measurements in the PDF of patients with pancreatic diseases offer a simple diagnostic aid in clinical differentiation of pancreatic pathology.
