Although comparative studies of anuran ontogeny have provided new data on heterochrony in the life cycles of frogs, most of them have not included Colombian species. Using different staining techniques, we describe the cranial and poscranial elements development...

Activation of immune response has been long assumed to be an energy-costly process but direct measures of changes in metabolic rate after eliciting immune response disputes the universality of this assertion. The acute phase response (APR) is the first line of...

The extensive coastlines of South Africa and Namibia extends from the Atlantic to the Indian Ocean and encompass several major biogeographic provinces, each characterized by unique faunal and floral assemblages. Recent biogeographic studies have led to competing...

Spinosaurids (Diapsida: Spinosauridae) and sphenacodontids (Synapsida: Sphenacodontidae) share not only a characteristic tall neural spines, but also an atypical – compared to their close respective relatives – ecology, i.e. apparently piscivorous and possibly...

Background. Repetitive species-specific sound enables the identification of the presence and behavior of soniferous species by acoustic means. Passive acoustic monitoring has been widely applied to monitor the spatial and temporal occurrence and behavior of calling...

Freshwater fishes often exhibit high genetic population structure due to the prevalence of dispersal barriers (e.g., waterfalls) whereas population structure in diadromous fishes tends to be weaker and driven by natal homing behaviour and/or isolation by distance....

Corals rely on a symbiosis with dinoflagellate algae (Symbiodinium spp.) to thrive in nutrient poor tropical oceans. However, the coral-algal symbiosis can break down during bleaching events, potentially leading to coral death. While genome-wide expression studies...
