Resumen
Forensic botany is a science that studies biological traces of plant origin with regard to their practical usefulness as evidence used in judicial proceedings. Among the disciplines of forensic botany, the following have the widest application: palynology, plant anatomy, diatomology, plant ecology and plant molecular biology. It has been shown that the knowledge of plants can be used to determine the connections between the alleged perpetrator, victim and crime scene. In practice, the methods of forensic botany have been used to identify locations where the hostages were held or the sites of concealment of a corpse, distinguish between the place of the incident and that where the victim was abandoned, identify the perpetrator, the cause and time of death, unravel drug distribution networks, clarify the circumstances of plant and animal smuggling as well as war crimes. Despite the fact that the suitability of forensic botany for determining the circumstances of criminal events has been repeatedly confirmed, this science remains largely underestimated and scarcely used. This article presents the current state of knowledge in the field of forensic botany, characterizes its specific disciplines, possibilities and limitations relating to the application of the methods of forensic botany in investigative practice as well as outlines the perspectives of its further development.

Resumen
Would you rather solve a forensics puzzle or take a lab practical? An alternative to the traditional lab practical can be used to assess students' skills and knowledge in plant cell biology and anatomy. This forensics project challenges students to analyze evidence from crime scenarios. The instructor supplies the scenarios, evidence collected at the crime scene, and type specimens. The students prepare the evidence and type specimens for analysis by light and polarized light microscopy and then document and report their findings. Students enjoy this project and are able to demonstrate their skills as well as their knowledge.

Resumen
Recently, Brazilian Federal Police used forensic chemistry and forensic botany techniques on a case. Two packets containing fragmented plant matter were seized and sent for forensic analysis. Forensic chemistry, the gold standard for evaluating plant material suspected to contain illicit substances, did not find illicit materials. Gas chromatography coupled mass spectrometry (GC-MS) identified thujone in the botanical material. Thujone is a chemical compound naturally found in many plant species, notably Artemisia absinthium. Because doubt remained, we next used plant DNA barcoding methods. Total DNA from plant tissue fragments was extracted and five different DNA regions were amplified, sequenced, and analyzed using plant DNA barcoding methods. Genetic analysis yielded 30 good quality sequences representing five taxa. Most specimens were identified as A. absinthium. Few studies focus on practical forensic applications of plant DNA barcoding methods using a case solved in a forensic laboratory with its difficulties and limitations. To the best of our knowledge, this is the first study to report an effective joint effort of forensic chemistry and botany techniques to assess plant material in Brazil. The availability of a new technical approach for the genetic sequencing of plant species will enhance many forensic investigations and inspire similar initiatives.

Resumen
Mammalian scavenging, disarticulating, scattering and removal of human remains can alter and obscure both soft tissue and skeletal remains which are essential to making interpretations and identifications during forensic investigations. The effects of scavenging vary between regions, environments, scavenger species, and crime scene scenarios due to a variety of factors. Nonetheless, there is a gap in the knowledge of scavenger species found within Northwestern Europe. The red fox (Vulpes vulpes) and Eurasian badger (Meles meles) are the largest wild mammalian scavenger species inhabiting peri-urban and rural environments within Northwestern Europe. These mammalian scavengers have dentitions and bite forces capable of heavily modifying and widely transporting human remains yet there are currently no species-typical and region-specific studies of these scavengers and their impacts on forensic investigations and physical searches for human remains. Forensic scientists, investigators and police search officers have been forced to rely on anecdotal evidence and scavenging studies focused on scavengers not found in this region. Scavenging studies have previously concentrated on scavenger species found in North America and Africa, such as coyote (Canis latrans), wolf (Canis lupus), hyena (Crocuta crocuta), lion (Panthera leo) and leopard (Panthera pardus), which have differing species-typical scavenging behaviour and patterns in comparison to foxes and badgers. Likewise, knowledge of the characteristics of the effects on bone surfaces of fox and badger scavenging is lacking, more so for the latter scavenger. The overall aim of this thesis is to aid forensic investigations by filling the gaps in the knowledge and identification of red fox and Eurasian badger species-typical scavenging behaviour and patterns. Avian scavenging can also modify soft tissue and skeletal remains. The buzzard (Buteo buteo) and carrion crow (Corvus corone) are the most common avian scavengers within this region. The scavenging behaviours of these avians modified soft tissue and affected mammalian scavengers’ scavenging behavours. A survey of police search officers within the U. K. indicated that the scavenging of surface deposited human remains within this region is common and that scavenging affects the recovery rates of remains. Despite the impact of scavenging on the recovery of scavenged remains, there is a lack of knowledge and literature available to forensic scientists, investigators, and police search officers to aid in the identification of scavenger species and scavenger species-typical scavenging behaviour and patterns. Thus these forensic professionals have been relying primarily on anecdotal evidence to identify scavengers or have not made efforts to identify scavengers. Experiments, conducted in southern England, using deposited deer (Cervus nippon; Capreolus capreolus) and the observation of captive scavengers found that within a woodland environment common scavengers include wood mouse (Apodemus sylvaticus), grey squirrel (Sciurus carolinensis), carrion crow, buzzard, Eurasian badger, and red fox. Scavenging activities by all scavenger species observed at remains were affected in various ways by seasonality, trophic resources, territoriality, insect activity, carcass size and condition, and decomposition. Of those scavengers, the red fox was the most frequent scavenger of surface deposited remains. The species-typical scavenging behaviour and pattern, as well as bite mark dimensions, of the red fox proved to differ to that of badgers and other canids, such as domestic dogs (Canis familiaris), coyotes and wolves. The benefits of the knowledge of scavenger species-typical scavenging behaviour and pattern to forensic investigations and physical searches were assessed by applying the results gained from the experiments within this research to current forensic investigations and search exercises performed with police search officers. The application of information on species-typical scavenging behaviour and patterns was found to improve police search officers’ search and recovery efforts of scavenged remains.

Resumen
Forensic Palynology has helped to solve crimes ranging from fraud to murder. Pollen is ubiquitous, almost indestructible and microscopic in size. It is often sticky and easily carried, undetected, from one place to another. As pollen is unique to a plant species, combinations of pollen types (pollen assemblages) present in soil or other samples can identify the type of environment, and often the exact location, from which a sample originated. Although Forensic Palynology has been used routinely in New Zealand for over 25 years, is commonly used in the United Kingdom and has been used in several cases in Australia in the past ten years, little research has been done in this field. In Australia, police require an initial broad palynological analysis of samples from a crime scene prior to approving a more detailed analysis. This project investigates palynological samples from two superficially similar environments that could potentially be a crime scene and alibi location, in order to determine if they can be broadly distinguished from each other. Two Perth metropolitan wetlands, Herdsman Lake and Eric Singleton Bird Sanctuary, were chosen for study as potential sites for assaults and clandestine burials. Four sites within each wetland, with correspondingly similar vegetation communities, were sampled at surface level in different seasons. At three sites, 50 cm cores were taken and sampled at seven levels to simulate shallow grave profiles. Samples were prepared and analysed using standard palynological techniques. Surface and core (grave profile) pollen assemblages were compared site by site within each wetland, and with the corresponding site of the other wetland. The grave profile assemblages for each core were combined and averaged to represent mixed 'burial assemblages', and similarly compared across and within wetlands. Palynological analysis established that the surface soil samples were characteristic of wetland environments. The different vegetation sites in each wetland, and the corresponding vegetation site in the other wetland, were broadly palynologically distinct. The season in which samples were collected was difficult to determine. Grave profile assemblages generally differed from surface samples at each site, and broadly differed across and between the two wetlands, but the differences in the 'burial assemblages' were less marked. The findings of this study confirm that broad palynological analysis can differentiate between two wetlands at surface level and downhole, and that samples at different depths in a grave should be separately analysed. Collection of control samples from similar and possible alibi environments is essential. Caution should be taken when palynologically interpreting the season in which a crime was committed.

Forensic botanical comparison can be hampered by the lack of appropriate DNA databases. In this study, we report on the use of the trnL intron and the trnL-trnF IGS in the chloroplast genome (cpDNA) and establish a DNA sequence database for plant species identification. The database comprises 365 individual sequences representing 79 families, 206 genera and 264 species. These plant species can be grouped to species level using both sequence and length polymorphisms at these loci. In blind trial testing, most of the blind samples matched their respective species from our local DNA database. Cluster analysis with Neighbor joining method of the two DNA regions from 80 samples of this study were constructed and clustered to both family and genus. The sequence database described in this study can be used to identify plant species using DNA sequences of the two loci and illustrates its value in plant species identification. Bidens pilosa L.with barbed fruits is dispersed via animal species resulting in a widespread distribution and therefore frequently collected when attached to evidential samples during criminal investigation. In this study, 161 specimens were used from these varieties comprising 11 different populations and 7 samples of Bidens biternata were included as an out-group control. DNA fragments of all samples at the trnL intron and trnL-trnF IGS loci of cpDNA, ITS1, 5.8S and ITS2 of nrDNA were amplified and sequenced. From the sequence types of the 5 loci, trnL intron, ITS1, ITS2 and 5.8S were found to be useful markers to differentiate Bidens biternata and Bidens pilosa. There were 84 haplotypes at the 5 loci from 161 specimens. Among 84 haplotypes, B. radiata could be almost differentiated from the varieties of Bidens pilosa using these 5 loci. It showed that the genetic diversity of nrDNA sequence was higher than that of cpDNA from the data of the number of polymorphic sites (S), number of haplotypes (H), gene diversity (Hd), nucleotide diversity (π) and genetic diversity (θ). From the results of the analysis of molecular variance (AMOVA), there are more than 50 % variance contributed by the variance of “within populations” in the loci of nrDNA and cpDNA. The gene flow between var. radiata and var. minor or var. pilosa showed lower than those between var. minor and var. pilosa, it indicated the significant hybridization phenomenon between var. minor and var. pilosa which naturalized earlier than var. radiata. In the case report of suspect seed samples, species analysis was performed by DNA analysis using the trnL-trnF IGS of cpDNA, and the ITS1 of nrDNA. Based on these analyses, it was determined that all seeds were from the species Cannabis sativa. The system established in this study provides a robust tool for cannabis seed identification.
