Cynolebias parnaibensis, a new seasonal killifish from the Caatinga, Parnaíba River basin, northeastern Brazil, with notes on sound producing courtship behavior (Cyprinodontiformes: Rivulidae) Neotropical Ichthyology
Costa,Wilson J. E. M.; Ramos,Telton P. A; Alexandre,Luisa C; Ramos,Robson T. C.
Cynolebias parnaibensis from the Canindé River drainage, Parnaíba River basin, northeastern Brazil, is described. It is considered to be a member of a clade endemic to the Caatinga. The clade is diagnosed, e. g., by a series of structural modifications of the pharyngeal jaw apparatus, which is related to the sound production exhibited by males during courtship behavior. The courtship sound of C. parnaibensis consists of a single pulse named as thump (duration 0.031-0.133s; interthump intervals 0.020-8.319s; dominant frequency 70.3-93.8 Hz). The new species is distinguished from all other congeners by a combination of 27-31 neuromasts around eye, 29-33 supraorbital neuromasts, 16-18 dorsal-fin rays and 19 anal-fin rays in males, 28-31 caudal-fin rays, 33-36...

Rodrigues,Sérgio Roberto; Fuhrmann,Juares; Gomes,Elias Soares; Amaro,Ricardo Aparecido.
Abstract Description of immatures and mating behavior of Liogenys bidenticeps Moser, 1919 (Coleoptera: Melolonthidae: Melolonthinae). Some species of Melolonthinae are associated with several species of cropped plants, with larvae consuming roots and, in some cases, are considered as crop pests. In some agricultural regions of Brazil, larvae of L. bidenticeps are found associated with cultivated plants, and little information is available about this taxon. This study, aiming at expanding the knowledge about the morphology and behavior of this species, provides the description of immatures and mating behavior of adults. The studies were conducted at the experimental farm of the Universidade Estadual de Mato Grosso do Sul in Aquidauana, Mato Grosso do Sul...

In order to evaluate the sexual behavior of Toggenburg goats fed with different dietary energy, 32 kids in reproductive age and free of any reproductive pathology were divided in 3 groups according to the dietary treatment. Group 1, maintenance (M) (n=11); Group 2, supplied energy 1.5 times energy maintenance (1.5M) (n=10); and Group 3, supplied energy 2.0 times energy maintenance (2.0M) (n=11). The estrus cycles of all kids were induced and synchronized by insertion of an intravaginal sponge impregnated with 60mg Medroxyprogesterone Acetate. An ultrasound scanner fitted with an 8.0-MHz linear transducer, adapted for small ruminants was used to determine ovulation time and females were tested for estrus twice daily after sponge removal by the use of a male...

Exposure of C57BL/6J Male Mice to an Electric Field Improves Copulation Rates with Superovulated Females OAK
HORI, Takuya; YAMSAARD, Thicomeporn; UETA, Yoshiko Yanagimoto; HARAKAWA, Shinji; KANEKO, Etsushi; MIYAMOTO, Akio; XUAN, Xuenan; TOYODA, Yutaka; SUZUKI, Hiroshi; 宮本, 明夫; 玄, 学南; 鈴木, 宏志.
It is well-known that there are considerable strain differences in the relative copulation rates between male and superovulated female mice. In particular, the C57BL/6J strain of mice has a lower rate of successful copulation. We examined the effect of exposure to an electric field on sexual behavior in C57BL/6J male mice. When C57BL/6J males were exposed to a 50 Hz, 45 kV/m electric field for 30 min per day for 11 days and placed in a cage with a superovulated female of the same strain, the successful copulation rates of males was significantly improved compared with unexposed males (P<0.05). These results suggest that the exposure of C57BL/6J male mice to an electric field improves their sub-fertility activity in mating with superovulated females.

Female calling and male flight orientation and searching behaviors in Callisphyris apicicornis: evidence for a female-produced sex attractant pheromone Ciencia e Investigación Agraria
Curkovic,Tomislav; Ferrera,Catalina.
Callisphyris apicicornis is a fruit pest of increasing concern in Chile. To aid in the identification of its sex pheromone for use in the management of this insect, "calling" (pheromone release) of females and "orientation and searching" behaviors of males to calling females were video recorded. Light intensity, wind speed, temperature, time of the day, and the frequency of individuals performing each step within both behavioral sequences were recorded as well. Drawings of the behavioral steps and ethograms (routes and returns) are also provided, including transition frequencies between behavioral steps. The calling behavior of females included diagnostic movements of the abdomen, legs, elytra, and wings, showing similarities to the descriptions of other...

Growing knowledge and understanding of dichromatism and sex reversal in Labridae Naturalis
Roede, Machteld J..
A brief survey is given of current literature in comparison with former studies. Since the 18th century phenotypic diversity of Labridae is a matter of argument. At first in dribs and drabs, yet last decades at a rapid rate, dichromatic adult morphs are synonymized. There are few monochromatic species. Wrasses are protogynous hermaphrodites. Most species are described as monandric, but a minority (of slightly or extremely dichromatic) species is diandric, with both primary and secondary males. Terminal males reproduce with single females, but initial phase males spawn in aggregations. Some species are haremic, and large males are permanently or temporarily territorial. Last decades insight in the various social factors has greatly increased, resulting in...

Marriage Behavior Response to Prime-Age Adult Mortality: Evidence from Malawi AgEcon
Ueyama, Mika; Yamauchi, Futoshi.
This paper examines the effect of AIDS-related mortality of the prime-age adult population on marriage behavior among women in Malawi. A rise in prime-age adult mortality increases risks associated with the search for a marriage partner in the marriage market. A possible behavioral change in the marriage market in response to an increase in prime-age adult mortality is for marriage to occur earlier to avoid women’s exposure to HIV/AIDS risks under the condition that the risks are higher during singlehood. We test this hypothesis using micro data from Malawi, where prime-age adult mortality has drastically increased. In the analysis, we estimate prime-age adult mortality that sample women have observed during the adolescent period by utilizing retrospective...

Mating time of the West Indian fruit fly Anastrepha obliqua (Macquart) (Diptera: Tephritidae) under laboratory conditions Neotropical Entomology
Henning,Frederico; Matioli,Sergio R..
Allochronic reproductive isolation seems to be an important factor in speciation processes in Tephritidae since specific mating times are a widespread feature of its species. The timing of matings of the West Indian fruit fly, Anastrepha obliqua (Macquart) was investigated through group-focal observations, during ten days, under laboratory conditions. The number of observed matings and males exhibiting calling behavior varied significantly according to time of day. Sexual activities seemed to be concentrated in the afternoon period, with the male calling behavior reaching a peak between 3:30p.m. and 4:30p.m., and mating occurred most frequently from 2:00p.m. to 4:30p.m.

Morphology of immature stages and mating behavior in Liogenys fusca (Blanchard) (Coleoptera, Melolonthidae, Melolonthinae) Rev. Bras. entomol.
Rodrigues,Sérgio Roberto; Morón,Miguel Angel; Gomes,Elias Soares; Bento,José Maurício Simões.
ABSTRACT Liogenys fusca is a rizophagous insect pest in various crops of economic importance in Brazil. Here we investigated the morphology of immature stages and mating behavior of this species. The redescription of the 3rd instar larvae of L. fusca in this work allows identification and registration of occurrence independently of adults, which occur sporadically in a certain period of the year. Male and female of L. fusca remained confined in the soil during the day and exited between 19:00 and 23:30 h. The copulations occurred between 19:30 and 21:00 h, and were characterized by a typical behavioral sequence. Copulation durations in L. fusca lasted on average 512.23 s. Adults were observed feeding before the copulations on leaves and inflorescences of...

Observations on the mating behavior of the eastern lowland olingo Bassaricyon alleni (Carnivora: Procyonidae) in the Peruvian Amazon Rev. Bras. Zool.
Williams,Sean M..
ABSTRACT The behavior of wild olingos is poorly known. From May-Jul 2015, I surveyed nocturnal mammals in southeast Peru and recorded the behavior of olingos. Multiple olingos were observed in close proximity on four occasions: two occasions in which multiple olingos were feeding on the inflorescences of a Parkia pendula tree; an adult and immature olingo traveling together; and a pair of olingos copulating. The copulation lasted at least 142 minutes, and was characterized by the male biting the hind neck and back of the female, constant female vocalizations, and rapid head turning by the female toward the male. Olingos and kinkajous were similarly abundant. These observations offer insight into the behavior of the wild olingo.

Prazosin blocks the glutamatergic effects of N-methyl-D-aspartic acid on lordosis behavior and luteinizing hormone secretion in the estrogen-primed female rat BJMBR
Landa,A.I.; Cabrera,R.J.; Gargiulo,P.A..
We have observed that intracerebroventricular (icv) injection of selective N-methyl-D-aspartic acid (NMDA)-type glutamatergic receptor antagonists inhibits lordosis in ovariectomized (OVX), estrogen-primed rats receiving progesterone or luteinizing hormone-releasing hormone (LHRH). When NMDA was injected into OVX estrogen-primed rats, it induced a significant increase in lordosis. The interaction between LHRH and glutamate was previously explored by us and another groups. The noradrenergic systems have a functional role in the regulation of LHRH release. The purpose of the present study was to explore the interaction between glutamatergic and noradrenergic transmission. The action of prazosin, an alpha1- and alpha2b-noradrenergic antagonist, was studied...
