Sugeak dira narrastien eta anfibioen artetik gehien erakartzen nautenak, eta hauen artean, sugegorriak gero eta interesgarriagoak iruditzen zaizkit. Kolorazio eta patroi aldetik dagoen aniztasuna ikaragarria da gainera. Urtea hasi berri gaudela, aurreko urtean zehar ikusitako sugegorri batzuk erakusteko aprobetxatuko dut. Arrazoi desberdinak medio, sugegorri dezente ikusteko aukera izan nuen 2021ean.

Entre todos los herpetos son las serpientes las que más me atraen, y entre ellas, las víboras me parecen cada vez más interesantes. Además, la diversidad de colores y patrones es enorme. Recién comenzado el año, aprovecharé para mostrar algunas víboras que he visto durante el año pasado. Por diferentes motivos, pude ver bastantes víboras en 2021. Leer más.

ubstantial molecular and morphological character differences lead us to the description of a new species of the genus Pristimantis from the cloud forest of Cerro Chucantí, Maje Mountains, Darien Province, as well as from several other mountain ranges in eastern and central Panama. Pristimantis gretathunbergae sp. nov. is a sister species to the allopatric P. erythropleura-penelopus group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.6% at COI.

Armoured, rigid bodied animals, such as Testudines, must self-right should they find themselves in an inverted position. The ability to self-right is an essential biomechanical and physiological process that influences survival and ultimately fitness. Traits that enhance righting ability may consequently offer an evolutionary advantage. However, the energetic requirements of self-righting are unknown.  Leer más.
