This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and an egg or ovum, the female gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. While both the female and male reproductive systems are involved with producing, nourishing and transporting either the egg or sperm, they are different in shape and structure. The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis. The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, ductus deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra. These glands include the seminal vesicles, prostate gland, and bulbourethral glands.

REVIEW Physiological Dependence on Copulation in Parthenogenetic Females Can Reduce the Cost of Sex
ANIMAL BEHAVIOUR, 2004, 67, 811e822 doi:10.1016/j.anbehav.2003.05.014 REVIEW Physiological dependence on copulation in parthenogenetic females can reduce the cost of sex M. NEIMAN Department of Biology, Indiana University, Bloomington (Received 6 December 2002; initial acceptance 10 April 2003; final acceptance 27 May 2003; MS. number: ARV-25) Despite the two-fold reproductive advantage of asexual over sexual reproduction, the majority of eukaryotic species are sexual. Why sex is so widespread is still unknown and remains one of the most important unanswered questions in evolutionary biology. Although there are several hypothesized mechanisms for the maintenance of sex, all require assumptions that may limit their applicability. I suggest that the maintenance of sex may be aided by the detrimental retention of ancestral traits related to sexual reproduction in the asexual descendants of sexual taxa. This reasoning is based on the fact that successful reproduction in many obligately sexual species is dependent upon the behavioural, physical and physiological cues that accompany sperm delivery. More specifically, I suggest that although parthenogenetic (asexual) females have no need for sperm per se, parthenogens descended from sexual ancestors may not be able to reach their full reproductive potential in the absence of the various stimuli provided by copulatory behaviour. This mechanism is novel in assuming no intrinsic advantage to producing genetically variable offspring; rather, sex is maintained simply through phylogenetic constraint. I review and synthesize relevant literature and data showing that access to males and copulation increases reproductive output in both sexual and parthenogenetic females. These findings suggest that the current predominance of sexual reproduction, despite its well-documented drawbacks, could in part be due to the retention of physiological dependence on copulatory stimuli in parthenogenetic females.

MATING SYSTEMS IN THE PLEUROTHALLIDINAE (ORCHIDACEAE): EVOLUTIONARY AND SYSTEMATIC IMPLICATIONS EDUARDO LEITE BORBA*, ARIANE RAQUEL BARBOSA, MARCOS CABRAL DE MELO, SAMUEL LOUREIRO GONTIJO & HENRIQUE ORNELLAS DE OLIVEIRA Departamento de Botânica, Instituto de Ciências Biológicas Universidade Federal de MinasGerais, Belo Horizonte, MG, 31270-901, Brazil * Corresponding author: [email protected] ABSTRACT. We developed a project addressing the determination of the reproductive system through experimental pollinations of species in the major genera representing all major lineages of Pleurothallidinae in order to determine occurrence of self-incompatibility in the subtribe, in which group it has possibly appeared for the first time, and how many times it has evolved. Additionally we surveyed the floral biology of species ofOctomeria , a genus with morphological characters typical of bee-pollinated flowers that was previously regarded as mellitophilous. At the moment, all but one of the species studied in selected large genera of the major lineages (Acianthera, Anathallis, Masdevallia, Octomeria, Specklinia, and Stelis) are self-incompatible. The species studied may possess complete, strong or partial self-incompatibility. We found two different sites where self-incompatibility reactions occur, the stigma and the stylar channel, and both sites were not found in the same genus except for Anathallis. In Anathallis, the two groups that differ morphologically (formerly Pleurothallis subgen. Specklinia sect. Muscosae

Here we report the sequencing and de novo assembly of the genome of the tiger tail seahorse, Hippocampus comes. Comparative genomic analysis identifies higher protein and nucleotide evolutionary rates in H. comes compared with other teleost fish genomes. We identified an astacin metalloprotease gene family that has undergone expansion and is highly expressed in the male brood pouch. We also find that the H. comes genome lacks enamel matrix protein-coding proline/glutamine-rich secretory calcium-binding phosphoprotein genes, which might have led to the loss of mineralized teeth. tbx4, a regulator of hindlimb development, is also not found in H. comes genome. Knockout of tbx4 in zebrafish showed a ‘pelvic fin-loss’ phenotype similar to that of seahorses. Members of the teleost family Syngnathidae (seahorses, pipefishes de novo.

Polygynandry, Extra-Group Paternity and Multiple-Paternity Litters In

DUGDALE,*† DAVID W. MACDONALD,* LISA C. POPE† and TERRY BURKE† *Wildlife Conservation Research Unit, Department of Zoology, University of Oxford, Tubney House, Abingdon Road, Tubney OX13 5QL, UK, †Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK Abstract The costs and benefits of natal philopatry are central to the formation and maintenance of social groups. Badger groups, thought to form passively according to the resource dispersion hypothesis (RDH), are maintained through natal philopatry and delayed dispersal; however, there is minimal evidence for the functional benefits of such grouping. We assigned parentage to 630 badger cubs from a high-density population in Wytham Woods, Oxford, born between 1988 and 2005. Our methodological approach was different to previous studies; we used 22 microsatellite loci to assign parent pairs, which in combination with sibship inference provided a high parentage assignment rate. We assigned both parents to 331 cubs at ≥ 95% confidence, revealing a polygynandrous mating system with up to five mothers and five fathers within a social group. We estimated that only 27% of adult males and 31% of adult females bred each year, suggesting a cost to group living for both sexes. Any strong motivation or selection to disperse, however, may be reduced because just under half of the paternities were gained by extra-group males, mainly from neighbouring groups, with males displaying a mixture of paternity strategies.
