Taxonomic status of Aotus hershkovitzi: its relationship to Aotus lemurinus lemurinus
Authors: Defler Thomas R. , Bueno Marta Lucia , Hernández-Camacho Jorge I.
Published: December 2023

We analyze various taxonomic problems of northern Aotus and describe the phenotype and karyotype of specimens, which have been called Aotus hershkovitzi since their discovery. Karyotypes from Panama with a diploid number of 2n = 55–56 had been referred to as Aotus lemurinus lemurinus but actually belong to Aotus lemurinus zonalis, a taxon found throughout the Pacific lowlands of Colombia, extending to Panamá and the Río Sinú on the Caribbean coast of Colombia. Aotus lemurinus zonalis is different phenotypically and karyologically from that of the Colombian Andes population (Aotus lemurinus lemurinus). We correct Hershkovitz’ designation of the Quindío Pass as an amended type locality for Aotus lemurinus. There are no solid grounds to reject the vicinity of Santa Fe de Bogotá as type locality, and this should be listed as the correct type locality. We then point out that as the karyotype of Aotus lemurinus lemurinus has not been described and as the specimens called Aotus hershkovitzi are phenotypically within the range of other Aotus lemurinus lemurinus, that Aotus hershkovitzi is a synonym for A. lemurinus lemurinus, which should now be recognized as having a diploid karyotype of 58 as well as the highest Fundamental Number (76) known for the genus. This interpretation is supported by the discovery of an Aotus (the Murrillo specimen) with 2n = 58 from the Cordillera Central. We suggest further that the karyotypes published for Aotus lemurinus griseimembra need to be confirmed with specimens from known collection sites and that, in fact, Aotus from lowland sites of the Caribbean coast may be another taxon, yet to be described. Furthermore, we clarify the unwarranted assumption that the origin of the “Quindío specimen” described karyologically by Torres et al. (1998) is from this region, but may represent an undescribed species from an as yet unidentified locality. Finally we suggest that in fact the “subspecies” of Aotus lemurinus may in fact be full species in light of their karyological differences. In order to clarify the Aotus species it is important to do specific systematic research, including the collection of specimens from specific localities.

Published: December 2023

Se presenta una sinopsis de las investigaciones con primates silvestres actualmente en desarrollo en México, basada en los resultados del reciente Foro de Primatología celebrado en Los Tuxtlas, Veracruz, México en Noviembre de 2002. Los temas de investigación de los trabajos presentados (N = 49) fueron censos de poblaciones silvestres, estudios ecológicos, estudios de conducta e investigaciones sobre aspectos fisiológicos y genéticos, así como problemas de conservación. A nivel de especies un número sustantivo de investigaciones se concentra sobre Alouatta palliata (43.1%) seguida por Ateles geoffroyi (35.3%) y Alouatta pigra (21.6%). Los estudios de primates en estado silvestre aportaron el 59% de los trabajos presentados, mientras que aquellos hechos en cautiverio contribuyeron al 41% (50% A. palliata y 50% A. geoffroyi). En el caso de los estudios en estado silvestre, aquellos llevados a cabo en paisajes fragmentados contribuyeron al 83% de los estudios reportados, mientras que los realizados en selvas extensas aportaron el 17% restante, señalando la necesidad de contar con más estudios de las tres especies en hábitats extensos. El 60% de los estudios se desarrollan en el estado de Veracruz (Los Tuxtlas) y el resto en distin- tos puntos en la península de Yucatán, Chiapas, Campeche y Tabasco. Estudios de poblaciones de primates en el noreste de México y en los estados de Guerrero y Oaxaca son inexistentes. A pesar de las lagunas de información sobre la distribución actual de las poblaciones de las tres especies de primates que existen en México, las investigaciones y entrenamiento de perso- nal se están intensificando y diversificando en cuanto a las localidades geográficas, especies y temas, aspectos que permitirán que crezca la información sobre la historia natural, ecología y comportamiento de las tres especies primates que existen en México, favoreciendo así su conservación.

Conserving the northern muriqui in Santa Maria de Jetibá, Espírito Santo
Authors: Mendes Sérgio L. , Santos Rogério R. , Carmo Luciano P.
Published: December 2023

The northern muriqui is known to occur in only 12 localities, with small populations restricted to isolated forest fragments. In the state of Espírito Santo the species is currently confirmed in only three localities: in and around the Augusto Ruschi Biological Reserve; the Caparaó National Park (which extends into the state of Minas Gerais); and forests in the municipality of Santa Maria de Jetibá. We are studying the muriquis in these last two areas. Both are in the central-southern montane region of the state. In the Caparaó Natoinal Park the aim is to census the population and to estimate its social and demographic composition. The muriquis have been found in part of the 18,200 ha on the Espírito Santo side of the park, and we believe that this population is the largest in the state. In Santa Maria de Jetibá, we hope to improve the prospects for the survival of the muriquis through the following activities: 1) monitoring and managing the populations; 2) studying genetic variability and endogamy; 3) developing a conservation education program, 4) testing the potential for ecotourism; and 5) promoting actions to improve the conservation and restoration of Atlantic Forest fragments. To date, we have found 84 individuals living in 13 fragments, with subpopulations varying from 1 to about 16 individuals. We have information on their presence in another 11 fragments. We have successfully translocated one young female and are monitoring its behav- ior. The current population and genetic data suggest that we need to improve the forest connectivity in order to reduce the fragmentation and isolation of the muriqui groups. The combined efforts of scientists, government, and the local people will be fundamental to achieve this.
The Caratinga Alliance: community-based conservation efforts to increase forest for the muriquis and water for the farmers
Authors: Pontual Francisco B. , Boubli Jean P.
Published: December 2023

The northern muriqui is Critically Endangered. About 25% of the known population lives in the 1,200 ha of secondary for- ests of the Caratinga Biological Station (EBC) Feliciano Miguel Abdala Private Natural Heritage Reserve (RPPN-FMA) and neighboring farms. Long-term survival of the muriquis there depends on an increase in the availability of suitable habitat. Widespread deforestation has depleted soil fertility and dried up the streams in the region. Community-based conserva- tion actions were carried out: 1) to protect and restore degraded areas to increase the availability of forests for the muriquis, and 2) to implement reforestation to improve the water balance vital for the regional recovery of rural production. Rural extension courses were provided for the local communities, which introduced modern production techniques to increase efficiency while decreasing environmental impacts. A new plant nursery was built and a pilot project to test forest restoration techniques was initiated.
Conservation research on the southern muriqui (Brachyteles arachnoides) in São Paulo state, Brazil
Authors: Talebi Maurício , Soares Pedro
Published: December 2023

In this paper we present an overview of the past and current conservation research on southern muriquis, Brachyteles arachnoides, in the state of São Paulo, most particularly in the forests of the Serra de Paranapiacaba, in four connected protected areas, which comprise the so-called Paranapiacaba Ecological Continuum: the state parks of Carlos Botelho, Intervales, and Alto Ribeira and the Xitué Ecological Station. These areas are the major stronghold for this species, and we discuss particularly the history of research on the muriquis of the Carlos Botelho State Park and the importance of statewide surveys and the establishment of further long term research sites to understand better its status and for the elaboration of management plans for its conservation.
The southern muriqui, Brachyteles arachnoides: ecology of a population in a semideciduous forest fragment
Authors: Martins Milene M.
Published: December 2023

Southern muriquis (Brachyteles arachnoides) inhabit evergreen and semideciduous forest fragments in southeastern Brazil. Contrary to the broadleaf evergreen forests, the seasonal mesophytic forests experience a relatively severe dry season, which affects the muriquis’ diet. Through behavioral sampling of feeding activity, I determined the diet of a group of muriquis in a semideciduous forest fragment. Leaves represented 55.3% of feeding records, flowers 16.1%, fruits 12.1%, and seeds 16.5%. Muriquis included 47 plant species in their diet. Leaf consumption was significantly higher in the dry season, but there was no evident difference between seasons in their feeding on either flowers, fruits, or seeds. Muriquis in this study shared only 11 taxa with groups in evergreen forests. The study group made consistent use of immature seeds. Dietary flex- ibility and the consumption of alternative resources may likely be advantageous where there are repeated lean periods and anthropogenic interference.
The southern muriqui, Brachyteles arachnoides, in the state of Paraná: current distribution, ecology, and the basis for a conservation strategy
Authors: Koehler Alexandre B. , Pereira Luiz César M. , Nicola Patrícia A. , Ângelo Alessandro C. , Weber Karla S.
Published: December 2023

Primatologists have suspected the existence of remnant populations of the southern muriqui, Brachyteles arachnoides (É. Geoffroy, 1806), in the state of Paraná since the early 1970s. Only in 2002, however, was this confirmed, with the discovery of a group in the upper Rio Ribeira valley. Here we report on some observations of this group, which totals 23 individuals living in a tiny remnant of the primary dense broadleaf forest that formerly extended in a continuous belt into Paraná’s first planalto along the valleys of the rios Ribeira and Açungui. We also discuss possibilities for the occurrence of muriquis elsewhere, and our ongoing efforts for the conservation of this threatened species in the state of Paraná.
Conservation genetics of the muriqui: past, present and future
Authors: Fagundes Valéria
Published: December 2023

Our understanding of the genetics of the muriqui have increased in recent decades. In the mid 1980’s the first data was obtained from polymorphisms of allozymes of 10 individuals of B. hypoxanthus (northern muriqui) from Minas Gerais, and two individuals of B. arachnoides (southern muriqui) from São Paulo. All specimens were considered to be of a single species. The DNA was extracted from blood samples, which required capture and anesthesia of animals. We can now extract mitochondrial DNA from feces samples. Analyzing more than 120 individuals of the northern muriqui from two populations, we are now able make inferences about genetic variability, population distinctiveness as well as intra- and interpopulation gene flow. DNA sampling through feces is reliable, efficient, and economic, and does not risk the physical integrity of the animals, and furnishes enough DNA that is easily reproducible for PCR amplification. Using this method it is possible to sample a greater number of individuals in nature than would be possible if live capture were necessary. A muriqui feces and DNA bank has been set up, and currently has samples of 230 individuals from seven of the twelve known populations of northern muriqui. The samples resulted from field studies, but more coordinated and systematic efforts among fieldworkers at the different muriqui sites are needed to improve representation across populations and species. Future perspectives include the use of new genetic markers (nuclear and mitochondrial DNA) to identify parents, offspring, and closely related individuals in captive and wild populations; to define units for conservation and the gene flow between them; to quantify genetic variability in the populations; to assess the rate at which genetic variation has been lost over time; to estimate the degree of inbreeding in the population; and to understand better the genetic differentiation of the two species.
Management of muriquis (Brachyteles, Primates) in captivity
Authors: Pissinatti Alcides
Published: December 2023

Muriquis are the largest of the Neotropical primates. Two forms are recognized today — Brachyteles arachnoides (É. Geoffroy, 1806), the southern muriqui with a black face, and Brachyteles hypoxanthus (Kuhl, 1820), the northern muriqui with face and genitalia mottled pink and black. They occur in eastern Brazil from the south of the state of Bahia to northern Paraná. The destruction, degradation and fragmentation of the Atlantic forest, along with hunting, are the reasons for their severely threatened status today. In this article, I briefly describe the history of conservation efforts and research on muriquis. Captive breeding, although still incipient as an effective conservation measure, has been successful at the Rio de Janeiro Primate Center (CPRJ/FEEMA) and the Curitiba Zoological Park, Paraná. I discuss particularly aspects of breeding success, cage design, colony formation, feeding and nutrition, diseases and the prevention and treatment of illnesses.
Age-related differences in palm-fruit handling and feeding durations in Cebus capucinus on the Osa Peninsula, Costa Rica
Authors: Chaney Morgan E.
Published: December 2023

Capuchin monkeys are well known for their large brains and a protracted juvenile period. According with one formulation of the needing-to-learn hypothesis for the evolution of extended juvenile periods, longer juvenility may be necessary for acquiring behaviors needed to exploit hidden or well-protected foods. I tested predictions of this hypothesis against observational data on the behavior of free-ranging Cebus capucinus at Piro Biological Station on the Osa Peninsula, Costa Rica. Small juveniles (ca. 1-3 years) appeared unable to follow the adult technique for processing the palm fruits of Attalea butyracea (Arecaceae), and large juveniles (ca. 3-5 years) spent significantly more time processing each fruit than did adult males and females. Furthermore, according to a ratio of feeding time to processing time, large juveniles were significantly less efficient than monkeys of both adult sexes in their foraging technique on this substrate. These findings show limited support for a foraging-focused formulation of the needing-to-learn hypothesis because they do not rule out alternative hypotheses, both ultimate and proximate, that would predict the same result.

Da stormfloden ramte
Authors: Andersen Camilla
Published: December 2023

I stigende grad oplever vi oversvømmelser efter massiv nedbør. Åløb, der går over sine bredder, og kyststrækninger, hvor kystprofilen blot rykker tættere og tættere på de danske boligejere. En af de største udfordringer som følge af klimaforandringerne og det stigende havspejl er, at kysterne er tæt bebygget. Vi ser ind i en fremtid, hvor oversvømmelser og stormfloder vil ramme endnu hyppigere og derved forme og forandre vores tilværelse. Men mennesket har i mange århundreder boet tæt ved kysten, og historien rummer en lang menneskelig erfaring med vandet og dets naturlige præmisser. En erfaring, som sjældent inddrages i de langsigtede løsninger i klimahåndteringen. Denne artikel belyser, hvordan stormfloder påvirkede mennesket, familien og samfundet forskelligt i 1800-tallet på Limfjordstangen, der er en fællesbetegnelse for de to kystsogne; Agger og Harboøre. Artiklen diskuterer, hvilken betydning tidligere erfaring havde for tilpasningsmulighederne i et risikoområde.

Hybrid implementation of the fastICA algorithm for high-density EEG using the capabilities of the Intel architecture and CUDA programming
Authors: Gajos-Balińska Anna , Wójcik Grzegorz M. , Stpiczyński Przemysław
Published: December 2023

High-density electroencephalographic (EEG) systems are utilized in the study of the human brain and its underlying behaviors. However, working with EEG data requires a well-cleaned signal, which is often achieved through the use of independent component analysis (ICA) methods. The calculation time for these types of algorithms is the longer the more data we have. This article presents a hybrid implementation of the fastICA algorithm that uses parallel programming techniques (libraries and extensions of the Intel processors and CUDA programming), which results in a significant acceleration of execution time on selected architectures.

Published: December 2023

In this note, based on a certain functional equation of the dilogarithm function, we establish nontrivial lower bounds for the p-adic valuation (where p is a given prime number) of some type of rational numbers involving harmonic numbers. Then we use our estimate to derive the integrality of some sequences of rational numbers, which cannot be seen directly from their definitions.

O capital intelectual é de vital importância para o sucesso da gestão democrática na educação. Partindo desse princípio surge a necessidade da gestão escolar estar atenta a formação e desenvolvimento desse capital intelectual, bem como lhe fornecendo as informações e estrutura necessária para o desenvolvimento do seu trabalho. Partindo dessa premissa nos deparamos diretamente com os fundamentos do capital intelectual e da gestão democrática, que estabelecem uma relação direta com o desenvolvimento da escola. O objetivo geral de pesquisa é analisar as implicações do capital intelectual na gestão democrática na educação. Para o alcance deste objetivo duas metodologias foram utilizadas: o estudo bibliográfico e uma análise qualitativa oriunda de observação realizada do capital intelectual na gestão escolar aliado aos princípios democráticos. A proposição proposta no estudo apresenta ações da gestão democrática nas escolas e no capital intelectual que estão alinhadas ao marco teórico do capital intelectual e da gestão democrática que as escolas devem se atentar.
Neuroendocrine Carcinoma with Bone Marrow Metastasis: A Case Series
Authors: Rajakumar Namrata N , Murthy Teena D , Vijay Raghavendra H , Balikai Girish
Published: December 2023

Neuroendocrine Neoplasms (NENs) account for 0.5% of all malignancies. Skeletal colonisation is often regarded as a rare event, and metastasis to the bone marrow occurs in the advanced stage of the disease, carrying a poor prognosis. In this report, the authors present three rare cases of Neuroendocrine Carcinomas (NEC) of the lung, diagnosed among 6766 bone marrow aspirations and biopsies performed at our institution between January 2019 and December 2022, highlighting the rarity of these cases. All three cases (63 years, 56 years and 73 years old male patients) presented to our institute at an advanced stage of the disease, with bone marrow involvement at the time of presentation. They exhibited nonspecific symptoms and had normal haematological parameters. Bone marrow aspiration and biopsy confirmed metastatic NEC. The aim of this case series was to investigate bone marrow involvement in NECs, along with their clinical and radiographic features, treatment, and follow-up. Bone marrow biopsy plays a crucial role not only in diagnosing haematological diseases but also in diagnosing and staging solid tumours. Future prospectives include adopting a multimodal approach for early diagnosis and treatment of NECs.

Published: December 2023

Rice is one of the foremost and principal food crops in the world, feeding more than four billion people primarily in Asia and India stands second in the production of rice after China with highest production. Even though rice is a staple food of Kerala, it occupies less than 7.7 per cent of the total cropped area. Kerala is known for its cultivation of paddy below the sea level. Salt water intrusion is the major problem in these areas. In this context, the present study aims to examine the efficiency of resource-use in paddy production in the salinity affected and the unaffected areas of Alappuzha District in Kerala. The study was based on the primary data collected from 50 rice farmers, viz 25 from salt water affected and 25 from unaffected areas and Cobb Douglas production function was used to estimate the resource use efficiency. The study revealed that the inputs viz., hired labour, manures and fertilizers, soil ameliorants, plant protection chemicals, machine and bullock labour power had a positive and significant effect on the rice yield in both salinity affected and unaffected areas. The returns to scale worked out for unaffected and affected farmers was 2.24 and 1.31 respectively. Chow test revealed that there is a significant difference in coefficients between the factors affecting yield of paddy among the salt water affected and the unaffected farmers. Marginal productivity analysis revealed that economic efficiency of all the variables except manures and fertilizers was more than one, indicating their sub-optimum usage and there exist the chances of improving the yield by the enhanced application of these inputs.

Published: December 2023

Field survey was conducted to determine the occurrence and damage severity of the citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracilariidae) in major citrus producing regions of Tanzania between December 2011 and September 2012. In total, 14,725 citrus trees and seedlings were assessed to determine the presence or absence of P. citrella as well as its associated damage severity. A total of 10,000 citrus trees (>5 years) were sampled from Morogoro Rural and Muheza Districts, while 4,725 nursery seedlings (<5 years) from Kinondoni District. The damage severity was assessed as described by Horsfall-Barratt scale. Results revealed that leafminers were recorded in nearly all surveyed areas. Kruskal Wallis analysis suggested minimal spatial distribution of the pest incidence among the surveyed locations. Kinondoni district recorded the highest (34.11%) leafminer incidence while Muheza district had the lowest (3.74). However, the damage severity indicated an increasing trend from December 2011 through June 2012 in nursery seedlings at Kinondoni. Weather variables (especially temperature) played an important role to the pest’s development and perpetuation. Further studies need to be conducted to have a wider knowledge of the pest in all the citrus growing regions in the country.
