Determining the cause and nature of the postmortem processes that living organisms experience is one of the main common issues faced by forensic experts,zooarchaeologists,palaeontologists,and other *** are among the most destructive agents that can interact with a corpse,since their feeding behaviour can lead to very extensive alterations,complicating the diagnostic identification of which carnivore species was responsible for the death of an individual,a livestock unit,or the formation of a fossil *** though some currently available techniques enable forensic experts to undertake a differential diagnosis of carnivore agency from corpse examination.

studies on litterfall and decomposition provide estimations of decomposition rates of different *** is key information to understanding ecosystem dynamics and changes in a scenario of global *** objective of this research was to assess litterfall production,the potential deposition of macro and micronutrients through leaf and twig fall as well as macronutrient—use efficiency in three forest ecosystems at different altitudes: a pine forest mixed with deciduous species(s1); a Quercus ***(s2); and,a Tamaulipan thornscrub forest(s3).Total annual litterfall deposition was 594,742 and 533 g m^(-2) for s1,s2 and *** litter was higher (68%) than twigs(18%),reproductive structures(8%) or miscellaneous material(6%).Micronutrient leaf deposition was higher for Fe followed by Mn,Zn and *** leaf deposition was higher for Ca followed by K,Mg and *** though P deposition in leaves and twigs was lower than other macronutrients,its nutrient use efficiency was higher than Ca,Mg or *** and species composition determine litter and nutrient deposition,with higher values at mid-altitudes(550 m).Altitude is an important factor to consider when analyzing litter production as well as nutrient deposition as shown in this *** production and nutrient deposition are expected to change in a scenario of global warming.
