I am pretty sure that it is a moldy core rot which would be caused by a fungus that infects the apple during the flowering stage. The fungi is also referred to as "apple fuzz". From SF Gate fungus sometimes does enter apples at the blossom end and damage the core, especially if weather is wet, a condition called "moldy core," From PennStateExtension ...

First off - this is an answer without citations. I looked for them, but couldn't find any. The terminology is undoubtedly described in reputable sources, but it is unlikely a paper is dedicated solely to explain this terminology, making literature searches tricky. Having said that - I discussed this question with an anthropologist and she agrees with my ...

Your question probably arises from a misunderstanding regarding the 'flooding' metaphor. I would not assume that 'flooded Earth's atmosphere with oxygen' means a lot of oxygen in the first place ... the metaphor means that oxygen levels rose from basically absent to noticeable. If you look at the history of oxygen in Earth's atmosphere you see a general ...

I've just recently discovered a range map site for ants: antmaps.org. Image: Interactive range map for L. niger from antmaps.org From the site's about section: antmaps.org is not a database per se, but rather a client-end tool for visualizing and interacting with the GABI database. The Global Ant Biodiversity Informatics (GABI) project (Guénard et al. ...

I think the Global Biodiversity Information Facility (GBIF) may be what you are looking for https://www.gbif.org. It is not limited to plants and insects.

There are no general rules. We have just observed repetitively that organisms living on small pieces of lands tend to be particularly large (insular gigantism) or particularly small (insular dwarfism) compared to the main land counterparts. There are several possible reasons for these changes and those reasons vary among species. Dwarfism is most definitely ...

The question is a bit confusing because it seems to be built on at least 5 misunderstandings. Allopatry and gene flow [..] allopatric speciation seen in the Galapagos finches. Adaptive radiation occurred because the finches flew from island to island, so there is gene flow [..] By definition, an allopatric speciation is a case of speciation where there ...

Whether something is considered a topographic barrier for an organism depends on the species being considered and its ability to traverse the terrain from one side of the barrier to the other. There's no blanket classification of what is considered a topographic barrier and what isn't. For example, a certain mountain range may be a topographic gradient to ...

Now I've found a range map site for lepidopterans of North America: https://www.butterfliesandmoths.org/taxonomy The Butterflies and Moths of North America (BAMONA) project is indebted to thousands of individual citizen scientists who participate in data collection and review. Nearly all of the sighting data and photographs available on the BAMONA ...

A comment on another SE post has made me aware of yet another source for arthropod maps: European Centre for Disease Prevention and Control's Tick Maps: The tick maps are published regularly to provide the ECDC stakeholders, the scientific community and the general public with updated information on tick distribution at ‘regional’ administrative unit ...

According to Yossef Braslevi, "HaYadata Et HaHaretz - Yam HaMelach Saviv Saviv" ("And you shall know the land - The Dead Sea and its Surroundings", 1956, Vol. C, page 199 -- the answer is positive. There were native addaxes in the Land of Israel.

According to these Wikipedia pages - https://en.wikipedia.org/wiki/Geologic_time_scale#Table_of_geologic_time, https://en.wikipedia.org/wiki/Precambrian - the Precambrian is a "supereon" not an "eon". The ICS International Chronostratigraphic Chart, ambiguously, puts "Eonothem/Eon" over both the "Precambrian" column and the "Hadean - Archean - Proterozoic" ...

Topograhpy refers to earth's physical features and a topographic barrier refers to physical features that prevent free movement from one position to another. As GForce pointed out, whether or not something is a barrier can depend heavily on the animal in question. A long, wide canyon can be a barrier for squirrels, but not for birds. Think of topographic ...
