Increasing urbanisation is encroaching into natural habitats and sometimes forcing wildlife into urban centres. Whether or not wildlife can thrive in an urban environment is dependent on many factors, one of which is how the species is perceived by local people. This study focuses on the city of Pilar in south-west Paraguay, which is home to a popu...

Pedophilia is a disorder of public concern because of its association with child sexual offense and recidivism. Previous neuro-imaging studies of potential brain abnormalities underlying pedophilic behavior, either in idiopathic or acquired (i.e., emerging following brain damages) pedophilia, led to inconsistent results. This study sought to explor...
Article
Background Social constrictions or the lack of a clear awareness about one's sexual orientation may influence the ability of individuals to explicitly declare their sexual preferences. Thus, the actual prevalence of males’ sexual attraction toward adult males, which is estimated by studies relying only on explicit questionnaires, may be biased. Con...

In Italy, 311,364 cases and 35,851 deaths of people who tested positive for SARS-CoV-2 were registered as of September 29th, 2020. To avoid the spreading of the virus, mathematical models predicting the course of infection’s spread ¹ become the basis to plan stringent countermeasures. We applied a published algorithm to real data up to September 27...

Article
Neurological disorders can be mis-diagnosed as psychiatric ones. This might happen to pedophilia emerging as a symptom of brain insult (i.e. acquired pedophilic behavior). This paper aims to delineate a behavioral profile that might help to identify defendants whose pedophilic behavior is likely to be the consequence of a neurological disorder. Thr...
Article
Full-text available
A growing number of researchers suggest that female homosexuality is at least in part influenced by genetic factors. Unlike for male homosexuality, few familial studies have attempted to explore maintenance of this apparently fitness-detrimental trait in the population. Using multiple recruitment methods, we explored fecundity and sexual orientatio...
Article
Full-text available
Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of...
Article
Full-text available
When a monkey selects a piece of food lying on the ground from among other viable objects in the near vicinity, only the desired item governs the particular pattern and direction of the animal’s reaching action. It would seem then that selection is an important component controlling the animal’s action. But, we may ask, is the selection process in...

Article
Here we respond to Vasey et al.'s critical comments regarding our article, “Societal norms rather than sexual orientation influence kin altruism and avuncularity in tribal Urak-Lawoi, Italian, and Spanish adult males” (Camperio Ciani, Battaglia, & Liotta, 20153. Camperio Ciani, A., Battaglia, U., & Liotta, M. (2015). Societal norms rather than sexu...
Article
Full-text available
The most popular model to explain how prehensile movements are organized assumes that they comprise two "components", the reaching component encoding information regarding the object's spatial location and the grasping component encoding information on the object's intrinsic properties such as size and shape. Comparative kinematic studies on graspi...
Article
Full-text available
Homosexual males could balance their low fitness by increasing benefits to relatives either through kin-directed altruism or by avuncularity (altruistic behavior toward the children of siblings). Evidence in support of kin selection and avuncularity includes the fact that homosexuals seem to be more empathic and altruistic than heterosexuals. Other...
Article
Full-text available
Sexual conflict likely plays a crucial role in the origin and maintenance of homosexuality in our species. Although environmental factors are known to affect human homosexual (HS) preference, sibling concordances and population patterns related to HS indicate that genetic components are also influencing this trait in humans. We argue that multilocu...
Article
Introduction: An unambiguous measurement of the rate of nonheterosexuality in the male population (male bisexuality and homosexuality) is essential to estimate the health risks associated with same-sex sexual behavior and to scale social and health programs for these citizens. However, self-reported questionnaires on explicit measures of sexual or...
Chapter
Sexual orientation, identity and desire is the final product of complex interactions between factors such as genetic influences, epigenetic, developmental pathways, both prenatal such as sex hormones, including the maternal factors acting on the foetus, and postnatal factors including shared environmental influences such as family education, social...
Article
Full-text available
Highly efficient systems are needed to link perception with action in the context of the highly complex environments in which primates move and interact. Another important component is, nonetheless, needed for action: selection. When one piece of fruit from a branch is being chosen by a monkey, many other pieces are within reach and visible: do the...
Article
Full-text available
Although there is a wealth of behavioral data regarding grasping movements in non-human primates, how posture influences the kinematics of prehensile behavior is not yet clearly understood. The purpose of this study was to examine and compare kinematic descriptions of grip behaviors while primates (macaque monkeys) were in a sitting posture or when...
Article
The search for evolutionary forces shaping the diversity of human personality traits encouraged studies that have found that islanders are relatively closed and introverted, with little interest in the external world. The ‘personality gene flow’ hypothesis was proposed to explain the mechanism underlying this difference, suggesting that the frequen...
Article
Full-text available
Humans show a spontaneous tendency to increase the velocity of their movements depending on the linear extent of their trajectory in order to keep execution time approximately constant. Termed the isochrony principle, this compensatory mechanism refers to the observation that the velocity of voluntary movements increases proportionally with their l...
Article
Full-text available
A variety of social, developmental, biological and genetic factors influence sexual orientation in males. Thus, several hypotheses have attempted to explain the sustenance of genetic factors that influence male homosexuality, despite decreased fecundity within the homosexuals. Kin selection, the existence of maternal effects and two forms of balanc...
Article
Full-text available
The prehensile hand is one of the major traits distinguishing primates from other mammal species. All primates, in fact, are able to grasp an object and hold it in part or entirely using a single hand. Although there is a wealth of behavioral data regarding grasping movements in humans and apes, there is relatively little material on macaques, the...

This research aimed to identify incidents of mothers in Italy killing their own children and to test an adaptive evolutionary hypothesis to explain their occurrence. 110 cases of mothers killing 123 of their own offspring from 1976 to 2010 were analyzed. Each case was classified using 13 dichotomic variables. Descriptive statistics and hierarchical...
Article
Introduction. Recent evidence suggests that sexually antagonistic genetic factors in the maternal line promote homosexuality in men and fecundity in female relatives. However, it is not clear if and how these genetic factors are phenotypically expressed to simultaneously induce homosexuality in men and increased fecundity in their mothers and mater...
Article
Whether personality differences exist between populations is a controversial question. Even though such differences can be measured, it is still not clear whether they are due to individual phenotypic responses to the environment or whether they have a genetic influence. In a population survey we compared the personality traits of inhabitants of an...
Article
Full-text available
This chapter provides empirical evidence bearing on three competing evolutionary genetic scenarios: neutral selection, mutation selection, and balancing selection. Using an innovative research design involving personality assays of inhabitants of three mainland villages and a host of nearby islands, it concludes that the findings support only the b...
Article
Introduction: Debate continues on whether or not male homosexuality (MH) is a result of biological or cultural factors. The debate persists despite the fact that these two sides have different abilities to create a scientific environment to support their cause. Biological theorists produced evidence, however, that these are not always robust. On t...
Article
Recent studies on male homosexuals showed increased fecundity of maternal female relatives of homosexual probands, compared to those of heterosexual controls. We have suggested that these data could be explained by the transmission, in the maternal line, of an X-linked genetic factor that promotes androphilic behavior in females and homosexuality i...
Article
Full-text available
There is a long-standing debate on the role of genetic factors influencing homosexuality because the presence of these factors contradicts the Darwinian prediction according to which natural selection should progressively eliminate the factors that reduce individual fecundity and fitness. Recently, however, Camperio Ciani, Corna, and Capiluppi (Pro...
Article
Full-text available
Several lines of evidence indicate the existence of genetic factors influencing male homosexuality and bisexuality. In spite of its relatively low frequency, the stable permanence in all human populations of this apparently detrimental trait constitutes a puzzling 'Darwinian paradox'. Furthermore, several studies have pointed out relevant asymmetri...
Article
Whether differences in personality among populations really exist and, if so, whether they are only due to cultural and linguistic differences or have a genetically selected adaptive value, is a controversial issue. In this research, we compared three Italian populations living on three small archipelagos in the Tyrrhenian Sea (n = 993), with their...
Article
An eight-year-long census and habitat evaluation of the Macaca sylvanus population was conducted in a 484-km2 area of the central region of the Middle Atlas Mountains in Morocco between June 1994 and October 2002. The authors walked a 93.5-km circuit – divided into 16 transect segments – 30 times with teams of trained research assistant volunteers,...
Article
Full-text available
The Darwinian paradox of male homosexuality in humans is examined, i.e. if male homosexuality has a genetic component and homosexuals reproduce less than heterosexuals, then why is this trait maintained in the population? In a sample of 98 homosexual and 100 heterosexual men and their relatives (a total of over 4600 individuals), we found that fema...
Article
Full-text available
We studiedMacaca sylvanus populations from a) a protected, relatively undamaged climax Cedar forest and b) a degraded, mixed Cedar-Oak forest. Animals exhibit considerable differences in demographic, social and time budget characteristics. In the degraded forest there were fewer social groups of smaller average group size and lower population densi...

Full-text available
We observed a mortal attack against an adult female in a wild population ofMacaca sylvanus in the Middle Atlas Cedar forest ecosystem near the town of Azrou, Morocco. This species is generally believed to be the least aggressive in the whole GenusMacaca. We investigated the possible factors responsible for such an extreme case of increased aggressi...

Full-text available
This brief review of comparative aspects of sexual strategies in animals, will focus on their behavioral flexibility rather than on fixed action patterns. Discussion will be on why sex is so common, but not universal, in animal species, and why males and females differ in their sexual strategies, and how each individual adapts its strategies accord...

We studied proxemic behaviour in an hospital waiting room by recording who chose to stand and who chose to sit and which chair, row and position. We distinguished sex and two categories of age, mature and old. We found that fenales sit together more easily than males and more frequently chose to sit close, especially mature ones. Males tend to keep...

A survey to evaluate the distribution of Procolobus kirkii on Pemba island (Tanzania) was conducted, 20 years after they had been translocated from Zanzibar in the Ngezi forest park. A team of both expert and trained observers, guided by the authors, censused 68.3 linear km of forest, corresponding to an estimated area of 3.5 km2 (63.6%) of the pro...

The cedar oak forest of the Middle Atlas in Morocco is not only the last of the large forests in the southern Mediterranean, but it also contains all the surviving forest biodiversity. This forest has been severely affected by drought, overgrazing by mixed herds of goat and sheep, and excessive logging for timber, firewood, and livestock fodder. Re...

Macaca sylvanus has a diploid chromosome number of 2n = 42. With the exception of chromosome 2 all chromosomes appear to have an identical banding pattern to most other macaque species. This chromosome has a clear band, localized immediately below the centromere; therefore, the karyotype of M. sylvanus more closely resembles that of the African Pap...

This paper presents the results of the Symposium on “Deforestation and reforestation: The Atlas Project”. From the studies presented appeared that at present the causes od deforestation do not arise so much from global climatic causes, but rather from human activity. Both the study conducted on the Nokopo population in Papua New Guinea, by Kocher S...

We investigated longterm socio-spatial relationships between adult males and immatures in a colony of Japanese macaques (Macaca fuscata fuscata), housed in a 1200 m2 indoor-outdoor enclosure at Cavriglia Natural Park (Arezzo, Italy). Using focal animal observations together with scan sampling, we found that the immatures between six months and one...

Guidelines for the use and care of nonhuman primates Summary - Recently, animal welfare has become a topic of interest for the scientific community and for laymen. In Italy, nonhuman primates are used for scientific research and for vaccine and drug quality control. The Italian Association of Primatologists has appointed a commission composed of et...
Article
The reproductive strategies of primates are explored from a socioecological and comparative perspective. This study shows that all primates respond to food distribution and predation risk in a predictable manner. Reproductive strategies are often the result of conflicting interess between the two sexes. Human reproductive strategies are then compar...
Chapter
Full-text available
In the present work we suggest that the laryngeal descent in the neck during hominization is not per se evidence of an early specific selective pressure on speech production, but can be explained as a morphofunctional consequence of the various splanchno- and neuro-cranial rearrangements caused by an extreme prefrontal cortex size increase during h...
Article
Full-text available
A hypothesis is presented which may explain within a single framework both the large behavioural differences and the large differences in head morphology between the great apes and humans. All these differences can be parsimoniously explained by a shift of few regulatory genes controlling the onset of the division of late migrating neurons in the h...
Article
A pilot field study was conducted in Sulawesi (Indonesia) to assess the status of macaque populations on the island. Wild and captive animals were sampled, mainly in border areas between presumed different species. The five species investigated were Macaca maurus, M. tonkeana, M. hecki, M. nigrescens, and M. nigra, for which morphological and gene...
Article
The G-banded karyotypes of 20 species of the tribe Papionini are remarkably similar, and the amount of phylogenetic interpretation permitted is limited. The genera Mandrillus and Cercocebus may be linked by a derived chromosome 10. T. gelada may be linked to the macaques by chromosome 2. Chromosome 5, which differs in M. fascicularis, makes this sp...

Field research was conducted in the winter of 1981–1982 on a free ranging population of 235 rhesus macaques (Macaca mulatta Zimmerman, 1788; Primates Cercopithecidae) divided into several troops, all living in a high mountain environment near the town of Simla (Himachal Pradesh), India. The scope of the research was to investigate the ecology and t...

A comparison of the 44-chromosome gibbons (27 animals from the taxa H. agilis, H. lar, H. klossii, H. muelleri, H. moloch and H. pileatus) shows that these species have a nearly identical, if not identical, G-banding pattern. Two chromosomes, No. 8 and the marker chromosome bearing the nucleolar organizing region, show intraspecific polymorphism. T...
Article
The intertroop agonistic behavior of a troop of Macaca mulatta villosa was studied in both forested and urban areas. Intertroop contacts lasted longer and were more likely to involve aggression in the town than in the forest. In particular, adult males and adult females when in urban areas showed a significantly higher rate of the most extreme form...

Full-text available
During field research on winter adaptation to a high mountain environment of the rhesus monkeys (Macaca mulatta), a newly established alpha male killed an infant less than 1 year old. This is the first case of infanticide witnessed in a natural free-ranging population ofM. mulatta. It seems likely that the infanticide was facilitated by the high po...

We aim to identify which are the most significant predictors suggesting acquierd paedophilia, to aid lawer and judges to adequately sentence or assign to rehabilitative programs. Acquired paedophiles misconduct follows organic impairment such as brain tumors, frontotemporal dementia, vascular brain insults, misdosage of parkinson treatment or traumatic lesions. These individuals as a consequenc of impulse control disorder and hyper-sexual confusion might start to abuse children. However their actions and profile follows a different path from other child sexual offenders. If identified these individuals more than other child sexual offenders, feel sense of guilt, comply with pharmacological treatment, and can be surgically or pharmacologically treated to total remission. Some legal sistem are indifferent to the difference between acquired and developmental pedophile, but other legal systems miss the existence of such cases. This work aim to help lawers to suspect acquired paedophilia in presence of certain predictors and request neurological in depth investigation to ascertain the issue. Finally on an humane bases we believe that independently from sentencing for family members one thing is to know that your relative is a child predator, another is to acknowledge that your relative is behaving out of carachter following a neurological impairment. We are currently profiling with multiple regression and cluster analysis around one hundred cases of pedophilia including a number of acquired paedophilia, and a number of undiagnosed suspect acquired pedophilia.
