Imene Chetoui et al.
The genetic structure of Mactra stultorum is inferred from partial sequence of a mitochondrial cox1gene and of the internal transcribed spacer region ITS1. The samples with two colors of shell (white and brown) were collected from three sit...

Albinism is a conspicuous and distinctive phenotype arising from the absence of melanin in the integument that has been documented in all major vertebrate groups. With few exceptions, albinism is rare in natural populations, suggesting that...

The article analyzes the results on the presence and organization of the muscle elements in the visceral organs of parasitic flatworms, trematodes, as well as their innervations. The different regions of the digestive, reproductive and excr...
Parallel shape divergence between ecotypes of the limpet Nacella concinna along the Antarctic Peninsula: a new model species for parallel evolution? [0.03%]
南极半岛纳氏短腹足动物(Nacella concinna)生态型的平行形态分化：一个新的平行进化模式物种？

María Carla de Aranzamendi et al.
Parallel phenotypic divergence is the independent differentiation between phenotypes of the same lineage or species occupying ecologically similar environments in different populations. We tested in the Antarctic limpet Nacella concinna the...
Migratory testis, spermatogenesis and reproductive cycle of the neotropical broad-eared bat Nyctinomops laticaudatus (Molossidae) [0.03%]
热带迁徙睾丸、精子发生和宽尾大嘴鼠蝙(Nicotinomops laticaudatus)( Molossidae)的生殖周期

We describe for the first time the displacement mechanism of migratory testis in Nyctinomops laticaudatus, which is little known in bats, in addition to histological analysis of its gonads. Data on testis anatomy and activity were obtained ...
Comparative study of stress responses, laterality and familiarity recognition between albino and pigmented fish [0.03%]

Oculocutaneous albinism is the result of a combination of homozygous recessive mutations that block the synthesis of the tyrosine and melatonin hormones. This disability is associated with physiological limitations, e.g., visual impairment ...
Fine details of the choanocyte filter apparatus in asconoid calcareous sponges (Porifera: Calcarea) revealed by ruthenium red fixation [0.03%]
ruthenium red 固定技术揭示钙质海绵(asconoid calcarean sponges)的 choanocyte 过滤器装置的细节结构

Andrey I Lavrov et al.
Sponges (phylum Porifera) are highly specialized filter-feeding metazoans, pumping and filtering water with a network of canals and chambers, the aquiferous system. Most sponges have a leuconoid aquiferous system, characterized by choanocyt...

Tissue changes during embryonic and postnatal development are critical for the success of physiological processes later in mammalian life. Dietary transition from milk to a variety of other food items is one of the factors inducing these ch...
Phenotypic variation among silverside populations (Atherinopsidae: Atherinella brasiliensis) from distinct environments in Northeastern Brazil [0.03%]
来自巴西东北部不同环境的银侧鱼群(Atherinopsidae: Atherinella brasiliensis)的表型变异

Ronaldo C Gurgel-Lourenço et al.
The successful adaptation of populations to a wide range of environments is a central topic in ecology. Based on the assumption that body shape may affect survival, we evaluated to what extent biotic and abiotic factors are capable of induc...
